Power supply unit for the monitor in the Chizhevsky chandelier. Power supplies for the "Chizhevsky chandelier"

In today's article, we will learn with you how you can make the “Chizhevsky Chandelier” at home with your own hands. So...

Most of us pay a lot of attention to what we eat and drink, what kind of lifestyle we lead, and at the same time we show absolutely insignificant interest in what we breathe.

“By building a home for himself,” said Professor A.L. Chizhevsky, “man deprived himself of normal ionized air, he distorted his natural environment and came into conflict with the nature of his body.”

In fact, numerous electrometric measurements have shown that the air of forests and meadows contains from 700 to 1500, and sometimes up to 15,000 negative air ions per cubic centimeter. The more air ions contained in the air, the more beneficial it is. In residential premises, their number drops to 25 per cubic centimeter. This amount is barely enough to maintain the life process. In turn, this contributes to rapid fatigue, ailments and even diseases.

You can increase the saturation of indoor air with negative air ions using a special device - an air ionizer, or ionizer. Already in the 20s, Professor A.L. Chizhevsky developed the principle of artificial air ionization and created the first design, which later became known as the “Chizhevsky Chandelier”. Over the course of many decades, Chizhevsky’s aeroionizers have undergone comprehensive testing in laboratories, medical institutions, schools and kindergartens, and at home and have shown the high effectiveness of aeroionization as a preventive and therapeutic agent.

Since 1963, after meeting A.L. Chizhevsky, the author of these lines has been introducing aeroionization into everyday life, since the scientist believed that the aeroionizer should enter our home in the same way as gas, water supply and electric light. Thanks to the active promotion of aeroionification, today “Chizhevsky Chandeliers” are manufactured by some enterprises. Unfortunately, their high cost sometimes prevents them from purchasing such devices for home use. It is no coincidence that many radio amateurs dream of building an air ionizer on their own. Therefore, the story will be about the simplest design, which even a novice radio amateur can assemble.

The main components of the air ionizer are an electroeffluvial “chandelier” and a voltage converter. An electroeffluvial “chandelier” (Fig. 1) is a generator of negative air ions. "Effluvium" means "flow" in Greek. This expression characterizes the working process of the formation of air ions: electrons flow from the pointed parts of the “chandelier” at high speed (due to high voltage), which then “stick” to oxygen molecules. The air ions generated in this way also acquire greater speed. The latter determines the “survivability” of air ions.

The efficiency of the air ionizer largely depends on the design of the “chandelier”. Therefore, special attention should be paid to its manufacture.

The basis of the “chandelier” is a light metal rim (for example, a standard gymnastic ring “hula hoop”) with a diameter of 750-1000 mm, on which bare or tinned copper wires with a diameter of 0.6-1 are pulled along mutually perpendicular axes with a pitch of 35-45 mm .0 mm. They form part of the sphere - a mesh that sags downwards. Needles no more than 50 mm long and 0.25-0.5 mm thick are soldered into the mesh nodes. It is desirable that they be sharpened as much as possible, since the current coming from the tip increases, and the possibility of the formation of a harmful by-product - ozone - decreases. It is convenient to use pins with a ring, which are usually sold in office supply stores (all-metal single-rod pin type 1-30 - this is the name of the product of the Kuntsevo Needle and Platinum Plant).

Three copper wires with a diameter of 0.8-1 mm are attached to the rim of the “chandelier” at 120° intervals, which are soldered together above the center of the rim. High voltage is applied to this point. At the same point, the “chandelier” is attached using a fishing line with a diameter of 0.5-0.8 mm to the ceiling or bracket at a distance of at least 150 mm.

A voltage converter is needed to obtain a high voltage of negative polarity that powers the “chandelier”. The absolute value of the voltage must be at least 25 kV. Only at such a voltage is sufficient “survivability” of air ions ensured, allowing them to penetrate into the human lungs.

For a room such as a classroom or school gym, the optimal voltage is 40-50 kV. It is not difficult to obtain this or that voltage by increasing the number of multiplying cascades, but you should not get too carried away with high voltage, since there is a danger of a corona discharge, accompanied by the smell of ozone and a sharp decrease in the efficiency of the installation.

The circuit of the simplest voltage converter, which has literally passed twenty years of repeatability testing, is shown in Fig. 2, a. Its special feature is direct power supply from the network.

Operating principle of the Chizhevsky Chandelier

During the positive half-cycle of the mains voltage, capacitor C1 is charged through resistor R1, diode VD1 and the primary winding of transformer T1. The thyristor VS1 is closed in this case, since there is no current through its control electrode (the voltage drop across the diode VD2 in the forward direction is small compared to the voltage required to open the thyristor).

During a negative half-cycle, diodes VD1 and VD2 close. A voltage drop is formed at the cathode of the trinistor relative to the control electrode (minus - at the cathode, plus - at the control electrode), a current appears in the control electrode circuit and the trinistor opens. At this moment, capacitor C1 is discharged through the primary winding of the transformer. A high voltage pulse appears in the secondary winding (step-up transformer). And so - every period of mains voltage.

High voltage pulses (they are double-sided, since when the capacitor is discharged, damped oscillations occur in the primary winding circuit) are rectified by a rectifier assembled using a voltage multiplication circuit using diodes VD3-VD6. The constant voltage from the output of the rectifier is supplied (through limiting resistor R3) to the electroeffluvial “chandelier”.

Resistor R1 can be made up of three parallel-connected MLT-2 with a resistance of 3 kOhm, and R3 - from three or four series-connected MLT-2 with a total resistance of 10...20 MOhm. Resistor R2 - MLT-2. Diodes VD1 and VD2 - any others for a current of at least 300 mA and a reverse voltage of at least 400 V (VD1) and 100 V (VD2). Diodes VD3-VD6 can be, in addition to those indicated in the diagram, KTs201G-KTs201E. Capacitor C 1 -MBM for a voltage not lower than 250 V, C2-C5 - POV for a voltage not lower than 10 kV (C2 - not lower than 15 kV). Of course, other high-voltage capacitors for voltages of 15 kV or more are also applicable. SCR VS1 - KU201K, KU201L, KU202K-KU202N. Transformer T1 is a B2B ignition coil (6 V) from a motorcycle, but you can use another one, for example from a car.

It is very attractive to use a TVS-110L6 horizontal scanning television transformer in the air ionizer, pin 3 of which is connected to capacitor C1, pins 2 and 4 to the “common” wire (the control electrode of the SCR and other parts), and the high-voltage wire to capacitor C3 and diode VD3 (Fig. 2.6). In this option, as practice has shown, it is desirable to use high-voltage diodes 7GE350AF or KTs105G and other diodes with a reverse voltage of at least 8 kV.

The aeroionizer parts should be mounted in a housing of appropriate dimensions so that there is sufficient distance between the terminals of high-voltage diodes and capacitors (Fig. 3). It is even better to cover these terminals with molten paraffin after installation - then you will be able to avoid the appearance of a corona discharge and the smell of ozone.

The aerial ionizer does not require adjustment and starts working immediately after being connected to the network. You can change the constant voltage at the output of the aeroionizer by selecting resistor R1 or capacitor C1. For some types of thyristors, sometimes it is necessary to select resistor R2 based on the moment the thyristor opens at the minimum mains voltage.

How to make sure that the air ionizer is working properly?

The simplest indicator is cotton wool. A small piece of it is attracted to the “chandelier” from a distance of 50-60 cm. By bringing (carefully!) your hand to the tips of the needles, already at a distance of 7-10 cm you will feel a chill - an electronic breeze - “effluvium”. This will indicate that the air ionizer is working properly. But to be more convincing, it is advisable to check its output voltage with a static voltmeter - it should be at least 25 kV (for household “Chizhevsky Chandeliers” a voltage of 30-35 kV is recommended). If you do not have the necessary measuring device, you can use the simplest method for determining high voltage. In a U-shaped plate made of organic glass, holes are drilled in the centers of the bends, an M4 thread is cut and screws are screwed in with the pointed ends of the heads facing outwards. By connecting one screw to the output terminal of the aeroionizer, and the other to the common wire, change the distance between the screws (of course, with the device disconnected from the network) so that an intense glow begins between their ends or a breakdown spark jumps. The distance in millimeters between the ends of the screws can be considered the value of the high voltage of the aeroionizer in kilovolts.

There should be no odors when the air ionizer is operating. This was especially stipulated by Professor A.L. Chizhevsky. Odors are a sign of harmful gases (ozone or nitrogen oxides), which should not be formed in a normally operating (properly designed) “chandelier”. When they appear, you need to once again inspect the installation of the structure and the connection of the converter to the “chandelier”.

Safety precautions

The aerial ionizer is a high-voltage installation, so precautions must be taken when setting up and operating it. High voltage in itself is not dangerous. The current strength is decisive. As is known, a current in excess of 0.03 A (30 mA) is life-threatening, especially if it flows through the heart area (left arm - right arm). In our aeroionizer, the maximum current strength is hundreds of times less than the permissible one. But this does not mean at all that touching high-voltage parts of the installation is safe - you will receive a noticeable and unpleasant sting from the discharge spark of the multiplier capacitors. Therefore, whenever you resolder parts or wires in a structure, turn it off from the network and short-circuit the high-voltage wire of the multiplier to the grounded (connected to the common wire) terminal of winding II (lower in the diagram).

About air ionization sessions

During the session you should be no closer than 1-1.5 m from the “chandelier”. A sufficient duration of a daily session in a regular room is 30-50 minutes. Sessions before bedtime have a particularly beneficial effect.

Remember that the aeroionizer does not exclude ventilation of the room - full air (i.e., normal percentage composition) should be aeroionized. In a room with poor ventilation, the air ionizer should be turned on periodically throughout the day at certain intervals. The electric field of the air ionizer cleans the air of dust. By the way, you can also use an air purifier for the same purposes.

Of course, the proposed voltage converter design is not the only one intended for repetition in amateur or industrial settings. There are many other devices, the choice of each of them is determined depending on the availability of parts. Any design that provides a DC output voltage of at least 25 kV is suitable. All designers trying to create and implement aeroionizers with low-voltage (up to 5 kV!) power supply should remember this. There was no benefit from such devices and cannot be. They create a fairly high concentration of air ions (measuring instruments record this), but the air ions are “stillborn”, unable to reach the human lungs. True, the air in the room is cleared of dust, but this is not enough for the life support of the human body.

There is no need to change the design of the “chandelier” - deviations from the design proposed by Professor A.L. Chizhevsky can lead to the appearance of foreign odors, the production of various oxides, which will ultimately reduce the effectiveness of the air ionizer. And it is no longer possible to call the different design the “Chizhevsky Chandelier”, since the scientist did not develop or recommend such devices. But profanation of a great invention is unacceptable.

This article discusses the assembly DIY Chizhevsky chandelier, which produces negatively charged air ions, it is also called an air ionizer.

A large number of measurements indicate that in one cubic centimeter of forest air there are from 600 to 1400, and sometimes up to 14,000 negatively charged air ions. The air will be more useful if there are a large number of these air ions. Unfortunately, in city apartments their content drops to 25 per cubic centimeter, which can result in significant fatigue and tiredness.

You can raise the level of air ions in the air of city apartments using a special device - the Chizhevsky ionizer. In the 20s of the last century, Professor Chizhevsky A.L. created the first such installation.

DIY Chizhevsky chandelier

This article will discuss a simple ionizer design that can be assembled do it yourself at home.

Chizhevsky chandelier consists of two parts - the chandelier itself and the high voltage converter circuit.

Chizhevsky's chandelier is an aluminum hoop with a diameter of up to 1 meter. Serviced copper wires with a diameter of up to 1 mm and with a pitch of 35 - 45 mm are attached to it, mutually perpendicular. The resulting mesh should sag at a distance of 60 - 90 mm. At the intersection of the wires, metal needles up to 40 mm long are soldered.

It is desirable that they be as sharp as possible, since the efficiency of the entire structure depends on this. It is necessary to attach three copper wires with a diameter of up to 1 mm to the hoop at an equal distance (every 120 degrees), which are soldered together at the other ends above the hoop. The high voltage generator itself is then connected to this point.

For effective operation of the Chizhevsky chandelier, a high-voltage voltage of at least 25 kV is required. For a room of approximately 50 sq. m requires about 30 kV to 40 kV. This can be achieved by adding to ionizer circuit the required number of multiplier stages. Below is a simple electrical circuit diagram of a high voltage generator for an ionizer, which has been tested for almost thirty-five years and has proven its effectiveness.

Description of the operation of an air ionizer for a Chizhevsky chandelier

At the moment of the positive half-cycle of the power supply, the capacitor C1 is charged through the chain of elements R1, VD1 and the winding of the transformer Tr1. Thyristor VS1 is locked at this moment. When a negative half-cycle arrives, diodes VD1, VD2 are in a locked state. A voltage drop is created at the thyristor cathode relative to the control electrode. An electric current appears in the electrical circuit of the thyristor control electrode and it opens. After this, capacitor C1 is discharged through the primary winding of transformer T1.

A high potential pulse appears in the secondary winding of the transformer and this is repeated every period. Electrical pulses of increased voltage pass through a rectifier assembled on diodes VD3...VD6 according to a voltage multiplier circuit. The rectified voltage from the output of this rectifier goes through the current-limiting resistance R3 to the chandelier.

Details and design of a homemade air ionizer

Transformer Tr1 - ignition coil B2B (6 V) from a motorcycle, but can also be used from a car. Resistor R1 can be assembled from three with a power of 2 W and a resistance of 3 kOhm, and resistor R3 from three or four for a total resistance of 10-20 MOhm.

Diodes VD3-VD6 high-voltage type KTs201G-E. Paper capacitor C1 is at least 250 V, C2-C5 are POV type capacitors for a voltage of at least 10 kV, and C2 is at least 15 kV. Thyristor VS1 KU202 K-N, KU201K. Any diodes VD1 and VD2 not lower than 400 V.

The ionizer parts must be installed in a housing of suitable dimensions so that there is a large distance between the terminals of the capacitors and high-voltage diodes. To prevent the occurrence of corona discharges in the ionizer, it is advisable to cover these terminals with molten paraffin after installation. When installed correctly, the Chizhevsky chandelier begins to work immediately.

There should be no odors during operation of the ionizer. The smell indicates the presence of harmful gases (nitrogen oxides or ozone). They should not appear near a properly working chandelier. If they appear, you need to inspect the device again and connect the ionizer to the Chizhevsky chandelier.

The output voltage can be changed by selecting resistance R1 or capacitance C1. You can verify the functionality of the ionizer by placing (carefully!) a piece of cotton wool near a working Chizhevsky chandelier. At about a distance of 50 mm it will be attracted to the chandelier. Also, at a distance of about 10 cm, a light breeze of air ions is felt.

Attention! Since the circuit elements are energized, electrical safety measures should be observed when setting up the ionizer.

Today, only the lazy don’t talk about health and a healthy lifestyle. People also do a lot to improve the health of their environment; they try to choose only those foods that cannot harm their body.

It is quite natural that everyone began to remember those methods of healing that were widely widespread back in the days of our parents. For example, today Chizhevsky’s chandelier has become relevant again. It’s not so easy to do it yourself, but all the effort is worth it!

What kind of chandelier is this?

Here we should make a small digression, talking about what kind of chandelier this is. What are its benefits? Well, let's look at this issue in more detail.

Professor A.L. Chizhevsky, whose works are now practically forgotten, at one time spoke about human stupidity in that part in which it concerned the completely careless attitude of people to the air. To the air that each of us breathes at every second of our existence.

He especially emphasized the role of negatively charged ions in shaping the health of the human respiratory system. The scientist cited as an example the fact that the air of an average-sized forest meadow or clearing contains up to 15,000 negatively charged ions per cubic centimeter! For comparison, a similar volume of air in an average city apartment contains no more than 15-50 ions!

Why is it needed, practical effect

The difference is visible to the naked eye. Unfortunately, people tend to underestimate dry facts, and therefore we will provide more specific information. The fact is that a low content of ions in the air contributes to the development of diseases of the respiratory system, leads to rapid fatigue and low performance.

Have you ever noticed that when you work outdoors you are much less tired? In particular, when working in an apartment, sometimes it’s enough to do a couple of small jobs around the house to feel completely overwhelmed. These are the negative consequences of a low content of negative ions in the air.

Chizhevsky’s chandelier helps combat this. We will try to make it with our own hands. This is what this article is about.

Main nodes

The most important element of the device is the electroeffluvial “chandelier”, as well as the transformer that converts the voltage. Actually, the negative ion generator itself is called a “chandelier” in this case. Negatively charged ions flow from its blades, which then simply stick to oxygen molecules. Due to this, the latter receive not only a negative charge, but also a high speed of movement.

Mechanical basis

For the base, a metal rim is taken, the diameter of which must be at least a meter. Every four centimeters, copper wires with a diameter of approximately 1 mm are pulled on it. They should form a kind of hemisphere that will sag slightly downwards.

Needles should be soldered into the corners of this sphere, the length of which is five centimeters and the thickness does not exceed 0.5 mm. Important! Needles should be sharpened to the highest possible quality, since in this case the likelihood of ozone formation, which is extremely harmful at home, is reduced.

By the way, this is why Chizhevsky’s chandelier should be made with your own hands as responsibly as possible, with strict adherence to all assembly diagrams. Otherwise, you may end up with equipment that does nothing to improve your health.

Mounting Notes

Three copper wires are attached to the rim, at 120° to each other. The diameter is at least 1 mm; they are soldered together exactly in the center of the chandelier. It is to this point that you should apply

Important! A fastening must be attached to the same point, which will be located at a distance of at least one and a half meters from the ceiling or ceiling beam. The voltage must be at least 25 kV. Only with such a value is sufficient vitality of ions ensured, allowing them to perform their health-improving functions.

Electrical circuits and operating principles

But the most important thing in our story is the diagram of the Chizhevsky chandelier, without which you are unlikely to be able to assemble anything useful. Let us immediately note that in an ordinary apartment you are unlikely to find everything you need for assembly, so you will have to drop into a radio equipment store.

When the positive half-cycle occurs, thanks to resistor R1, diode VD1 and transformer T1, capacitor C1 is fully charged. SCR VS1 in this case is necessarily blocked, since no current passes through its control electrode at this moment.

If the half-cycle is negative, diodes VD1 and VD2 are blocked. The voltage drops significantly at the trinistor cathode compared to the control electrode. Thus, a minus is formed at the cathode, and a plus is obtained at the control electrode. Accordingly, a current is generated, as a result of which the thyristor opens. At the same moment, capacitor C1 is completely discharged, which passes through the primary winding of the transformer.

Since a step-up transformer is used, a high voltage pulse appears in the secondary winding. The above process occurs during each tension period. Please note that high voltage pulses must be rectified, since when discharging through the primary winding,

For this purpose, a rectifier is used, which is assembled on diodes VD3-VD6. It is from its output that the voltage comes (don’t forget to install resistor R3) to the “chandelier” itself.

The Chizhevsky chandelier circuit we described can also be found in any Soviet magazine for radio engineering enthusiasts, but in any case it is useful to describe its operating principle. Without this, it will be more difficult to understand some of the nuances of the assembly.

Some important information

Resistor R1 can be made up of three MLT-2 connected in parallel. The resistance of each is at least 3 kOhm. We also make up resistor R3 from the same ones, but here MLT-2 you can take four of them, and their total resistance should be about 10...20 MOhm.

On R2 we take one MLT-2. You should not take cheap varieties of all of the above components: such a power supply for a Chizhevsky chandelier may well cause a fire, simply not being able to withstand the voltage.

You can take almost any diodes VD1 and VD2, but the current must be at least 300 mA, and the reverse voltage must be at least 400 V (on diode VD1) and 100 V (VD2). If we talk about VD3-VD6, then for them you can take KTs201G-KTs201E.

We take capacitor C1 MBM, which can withstand a voltage of no less than 250 V, C2 and C5 we take POV, designed for a voltage of no less than 10 kV. In addition, C2 must withstand at least 15 kV. Of course, it is quite acceptable to take any other capacitors that can withstand a current of 15 kV or more. In this case, Chizhevsky will cost less. As a rule, many of the necessary components can be pulled out of old radio equipment.

SCRs and transformer

SCR VS1 can be selected from KU201K, KU201L or KU202K-KU202N. The T1 transformer may well be made from the classic B2B (6 V) from any Soviet motorcycle.

However, no one forbids taking a similar part from a car for this purpose. If you have an old television set TVS-110L6, then this is very good. Its third terminal must be connected to capacitor C1, the second and fourth terminals are connected to the common wire. The high-voltage wire must be connected to the capacitor SZ and diode VD3.

This is roughly how a Chizhevsky chandelier is made with your own hands. As you can see, you need to have at least basic knowledge of electronics. Do not believe those charlatans on the Internet who talk about the possibility of assembling such a “chandelier” from scrap materials, since this is virtually unrealistic.

How to check the functionality of the design

How can you be sure that the structure assembled with such labor works normally? We suggest using the most reliable and primitive tool for this - a small piece of cotton wool. Even the simplest Chizhevsky chandelier, a photo of which is in the article, will definitely react to it.

It is known that even a small bundle of cotton fibers will begin to be attracted to the chandelier from a distance of about half a meter. If you simply bring your hand to the needles of the chandelier, then already at a distance of 10-15 cm you will feel a distinct chill, which will indicate that the equipment is in full working order.

By the way, if you decide to make a compact version of the ionizer, the needles can be replaced with one metal plate with teeth. Of course, the efficiency of such a device will be much lower, but it is quite suitable for improving the air quality around the workplace.

Some information about the correct conduct of ionotherapy sessions

Remember that Chizhevsky’s chandelier, reviews of which in most cases indicate its beneficial effects on the body, must be located at a distance of at least one and a half meters from a person. Sessions should be conducted for a maximum of 45-50 minutes. It is best to do this before bed, when fresh ionized air will help relieve stress and recharge your batteries for the next working day.

Secondly, you should remember that it is useless to ionize stuffy and stale air. If there is only carbon dioxide in the room, then there will be absolutely no benefit from this event.

By the way, the ionizer can be used effectively in the southern regions, where heavy air dust is a big problem. In this regard, the Chizhevsky chandelier, reviews of which confirm this, is capable of depositing dust even under conditions of low humidity.

Where can it be used?

Of course, we told you only about one ionizer design, which is quite suitable for use not only at home, but also in industrial conditions. In principle, you can upgrade the circuit yourself. It should only be taken into account that the output voltage must be no less than 25 kV. By the way, we remind you once again that on the Internet you can often find a diagram (do-it-yourself Chizhevsky chandelier), in which the output voltage on the rectifier is even less than 5 kV!

We assure you that such a device does not bring any practical benefit. Yes, a “budget chandelier” will create a certain concentration of negatively charged ions, but in their mass they will be too heavy and therefore unable to circulate in the air flow of the room.

However, such devices can be successfully used as a room purifier from dust in the air, which will simply settle. After all, Chizhevsky’s chandelier is not his advanced purifier. For this, it is much better to use a regular air conditioner.

But! Remember also the fact that any fundamental changes to the design, which was proposed by Chizhevsky himself, are strictly contraindicated. If you do not understand electrical engineering and physiology, then experiments will only lead to a decrease in the efficiency of the device, as well as to the production of an insufficient number of ions. You will only waste electricity in vain, getting absolutely nothing in return.

In general, a DIY Chizhevsky chandelier (a photo of which is in the article) will provide an excellent opportunity to save money on expensive medical equipment and make your life healthier.

Content

A device designed to ionize the air in the house is called a Chizhevsky lamp or chandelier. For modern people, such a device allows them to feel like they are in the forest and smell the smell after a thunderstorm in their own apartment. The ionizer helps improve conditions in many diseases and normalizes the body's metabolic processes. A chandelier cannot replace walks in the fresh air, but it can maintain the tone of a city person who has not yet been able to get out into nature.

What is a Chizhevsky chandelier

The human body cannot exist without air. Our health and well-being depend on its quality and composition. One of the components of air is ions, which carry a positive or negative charge, which is determined by the number of electrons. To change the number of electrons in the air, a Chizhevsky lamp is used - the first ionizer invented.

What is an air ionizer for?

A modern apartment or house has a lot of equipment that brings comfort to residents, but saturates the air with positive oxygen ions. The result is a deficiency of negative charges. The design of the Chizhevsky lamp, which can have different designs, is based on an electrode. When the chandelier is turned on, it produces electrons, which give the flow of particles in the air a negative charge. The development is designed to neutralize the effects of technology and give the air space a sufficient amount of negative ions, similar to forest ones.

Benefits and harms

Air ionization using a chandelier is a process whose benefits scientists have not stopped arguing for more than half a century. With the necessary negative charges of oxygen ions, the air masses are cleansed and disinfected from bacteria, but an excess of particles can cause harm to living organisms. Achieving an optimal balance is extremely difficult, so the question of the benefits and harms of a lamp is ambiguous. It has been established that air purification with the Chizhevsky device leads to the possibility of improving the condition of patients with certain diseases, including:

  • bronchitis, rhinitis, laryngitis;
  • asthma;
  • tuberculosis (initial stage);
  • allergy;
  • hypertension;
  • neurosis;
  • whooping cough.

The device has a positive effect on the healing process of wounds and burns. Air ionization will be useful for various infectious diseases. The device helps with general poor health, fatigue, and weakness. Other positive effects of the chandelier on the body are also noted:

  • increased performance and the ability to withstand heavy loads;
  • reducing the risk of heart attack and stroke;
  • normalization of respiratory exchange;
  • strengthening the immune system;
  • reducing the risk of spreading infections;
  • improved mood.

The numerous cases in which a chandelier can be beneficial do not in any way reduce the potential harm to the body from its use. Studies have shown that the Chizhevsky device can cause the following conditions:

  • wheezing when breathing or other problems with lung function;
  • violation of the heart rhythm;
  • the appearance of headaches;
  • deterioration in general well-being due to additional stress on the body.

How does an air ionizer work?

The operating principle of the Chizhevsky air ionizer is simple. The main element of the chandelier is the electrode. It is supplied with high voltage (20-30 kilovolts), generated in a system of two electrodes. They have different radii, the smaller one has a needle installed. The second electrode is the wire through which voltage is transmitted. Electrons are released from the surface of the needle, which collide with air molecules and form a negatively charged ion. When a person inhales air ions, they will transfer their charges to red blood cells, which will affect metabolic processes.

Instructions for using the Chizhevsky chandelier

In order for the Chizhevsky air ionizer to benefit residents, the device should be used carefully. The first session should not exceed 30 minutes. Gradually, the operating time of the chandelier increases to 3-4 hours a day. It is considered normal for city residents if headaches and dizziness occur during the first sessions. Such sensations can be caused by unusually clean air. Reduce the operating time of the chandelier to avoid negative consequences. There are a number of rules for installing a lamp:

  • ceiling height – at least 2.5 m;
  • indoor air humidity – up to 80%;
  • there should be no toxic substances in the air;
  • the distance from the chandelier to equipment and television equipment is at least 2.5 m;
  • There should be a space of 0.5 m between objects in the room and the ionizer.

DIY air ionizer

You can make Chizhevsky’s device yourself. To do this, you will need a metal hoop, the diameter of which does not exceed one meter. Copper wires (diameter up to 1 mm, tin-plated) should be secured to it with a slack. They need to be placed mutually perpendicular at a distance of 35-45 mm from each other. Sharp metal needles are soldered to the intersection of the wires. You will also need to solder three copper wires with one end at an equal distance to the hoop, and connect the other ends together above it. The generator is connected to this connection.

Scheme

There are several circuits for high-voltage power supplies for a Chizhevsky lamp, using which even a novice radio enthusiast can assemble the device. For example, a chandelier circuit for ionization may consist of the following elements:

  • fuse (low resistance resistor);
  • voltage divider (two resistors);
  • diode bridge;
  • timing chain;
  • capacitor;
  • two dinistres;
  • diode;
  • outputs to the transformer winding.

Contraindications of the Chizhevsky chandelier

Manufacturers of ionization chandeliers claim that there are no direct contraindications to the use of the equipment. All prohibitions are established for reasons of safety and caution when using devices, and not because of the research being conducted. There are theories according to which it is better not to carry out recovery with the help of Chizhevsky’s scientific development for the following problems:

  • atherosclerosis grade 3;
  • tuberculosis stages 2 and 3;
  • oncology;
  • renal hypertension;
  • heart failure of 1 and 2 degrees;
  • severe vascular sclerosis;
  • conditions after myocardial infarction, cerebral hemorrhage.

What to consider when purchasing

Before purchasing a chandelier for air ionization, be sure to read the technical data sheet of the device. The manufacturer must indicate the area for which the device is designed, operating voltage, power consumption, and specific ionization. The parameters for choosing the area and power of the chandelier are simple and clear. You need to know the size of your premises and network performance. The operating voltage should vary between 20 and 30 kW. Specific ionization is a parameter that determines the operating time of the Chizhevsky device required to purify the air.

Price

In online stores in Moscow, St. Petersburg and other cities of Russia, various Chizhevsky devices are sold, differing in ion concentration, radiation voltage, design and the presence of additional options. Depending on the specified features, chandeliers may have different prices. You can buy a Chizhevsky device for ionization cheap or expensive, choose according to parameters, look at its appearance from the photo, study the manufacturer’s description, and then order delivery by mail.

It is well known that the air in our residential and industrial premises differs from the natural air environment. But not only pollution. Measurements have shown that if the air of forests and meadows contains from 700 to 1500 negative aerons per cubic centimeter (sometimes up to 5000 ions / cm 3), then in residential premises their concentration sometimes decreases to 25 ions / cm 3. What, how It turns out that it is not at all indifferent to human health - a number of our ailments are associated precisely with this deficiency. In the 1920s, Alexander Leonidovich Chizhevsky (1897-1964) drew attention to the importance of the air ion composition, who also proposed a method for its normalization. The author of this work, Boris Sergeevich Ivanov, has been introducing aeroion technology into our everyday life for many years. We introduce the reader to the “Chizhevsky chandelier” of his design. The main components of the air ionizer are an electroeffluvial “chandelier” and a voltage converter. The name “chandelier” reflects the process of formation of air ions (effluvium - outflow): electrons flow from the pointed parts of the chandelier at high speed due to high voltage. By “sticking” to oxygen molecules, they move away from the place of their formation, thereby influencing the aeroionic composition of the air environment of the entire room. The efficiency of the air ionizer depends on the design of the “chandelier” and the dimensions of certain of its parts. It is, of course, possible to make it “better”, but it is unlikely that it will be possible to evaluate the result - the aeroionic composition of the emitted substance, its energy. The basis of the “chandelier” is a light metal rim (for example, an ordinary gymnastic ring “hula hoop”) with a diameter of 750...1000 mm, on which bare or tinned copper wires with a diameter of 0.6 are pulled mutually perpendicular with a step of 35...45 mm ... 1.0 mm. This checkered mesh, sagging, forms part of a spherical surface (see Fig. 139). Needles no more than 50 mm long and 0.25...0.5 mm thick, for example, pins with a ring at the end, are soldered to the mesh nodes. The sharply sharpened tip of the needle increases the operating current of the “chandelier” and reduces the release of ozone and nitrogen oxides that are undesirable here. At an angle of 120°, three copper wires with a diameter of 0.8...1.0 mm are attached to the rim of the chandelier, which are soldered together above the center of the rim. High voltage will be supplied to this point; it, connected through an insulator to the ceiling or a special bracket, will also be the suspension point of the “chandelier”. As a suspension-insulator, you can take a fishing line with a diameter of 0.5...0.8 mm. Its length must be at least 150 mm. A power source with a voltage of at least 25 kV is connected to the “chandelier”. Only at such a voltage is sufficient “survivability” of air ions ensured and their ability to penetrate into the human lungs is preserved. For large premises, for example, gyms, the voltage on the “chandelier” can reach 40...50 kV (a prerequisite is the absence of a corona discharge, which is easy to detect by the smell of ozone).

During the positive half-cycle of the mains voltage, capacitor C 1 is charged through resistor R 1, diode VD 1 and the primary winding of transformer T 1. Thyristor VS 1 is closed, since there is no current through its control electrode (voltage drop across diode VD 2 in this mode small compared to the opening voltage of the thyristor).

During a negative half-cycle, the diodes VD1 and VD2 close and a voltage sufficient to open it arises between the cathode and the control electrode of the thyristor. This leads to the fact that capacitor C1 is discharged through the primary winding of transformer T1 and a “pack” of bipolar pulses, rapidly decreasing in amplitude, appears on its step-up winding (the oscillatory process is due to low losses). This process is repeated in each period of the mains voltage. The voltage multiplier - diodes VD3-VD6, capacitors C2-C5 - is made here according to the classical scheme. Resistor R1 can be composed of three parallel-connected MLT-2 3 kOhm resistors, and R3 - of three or four series-connected MLT-2 resistors with a total resistance of 10...20 MOhm*. Resistor R2 - MLT-2. Diodes VD1, VD2 can be different - with a current of at least 300 mA and a reverse voltage of at least 400 V (VD1) and 100 V (VD2). Diodes VD3-VD6 can be replaced with KTs201G(D, E). Capacitor C1-type MBM for a voltage of 250 V, SZ-S5-POV for a voltage of at least 10 kV, S2-POV for a voltage of at least 15 kV. Thyristor VS1 - KU201K(L), KU202K(N). Transformer T1 - ignition coil B2B (6 V) from a motorcycle. The air ionizer is mounted as is customary in high-voltage devices - on insulators with good surfaces, with sufficiently large distances between the poles, smooth soldering and so on.

The aerial ionizer does not require adjustment. You can change the voltage at its output by selecting resistor R1 or capacitor C1. The simplest indicator of the normal operation of an aeroionizer is cotton wool: a small piece of it should be attracted to the “chandelier” from a distance of 50...60 cm. To check the voltage on the “chandelier”, you can, of course, use an electrostatic voltmeter. In household “chandeliers” it is recommended to set the voltage within 30...35 kV. When the air ionizer is operating, there should be no foreign odors (signs of the appearance of ozone and nitrogen oxides), this was especially stipulated by Chizhevsky.

About safety precautions. Although the current generated by accidentally touching the “chandelier” is very small and does not in itself pose a danger, such a discharge, of course, will not bring much pleasure. And falling from a height after being hit can have very real consequences. Therefore, when doing any work with the “chandelier”, it is necessary not only to disconnect it from the network (both wires), but, by closing the high-voltage output of the converter to the common wire, to discharge all capacitors. The author recommends “taking ions” as follows: distance from the “chandelier” -1 ... 1.5 m, time 30 ... 50 minutes. And so - every day, better - before bed.

When the “chandelier” is closed, the full output voltage of the converter will be applied to resistor R3 and its constituent resistors can be broken (the maximum permissible voltage for the MLT-2 resistor is 750 V). Here a high-voltage resistor would be preferable - for example, KEV-5.
