What is the price of a fluorescent lamp? (Schemes on the wire)

Title: Luminescent

Droselt (ballast) is an essential attribute for almost any fluorescent lamp. In the article below, we will see how the device looks like, how it works and why it is necessary to use a fluorescent lamp inductor.

For what kind of ballast equipment?

Before, let’s remember and speak for the throttle, we’ll figure out some how to represent the ballast and how to serve. For yes, dissuade me from theses, ask, and it is necessary to understand how a fluorescent lamp (LDS) works. Some and razgledame schematically presented.

Diagram explaining the LDS device

In front of us is a glass flask under the format for a tube, two tungsten spirals - an anode and a cathode - are placed on the edges of the flask. Samata requires an inert gas with little addition to the livestock. If the work voltage is applied to the anode and cathode, the lamp is not so bright - the resistance to the inert gas is high and not so strong between the electrode.

In order to start the device, it is necessary to heat up the coil. Vednaga trace kato se will be flooded, still more thermionically izlchvane, kato kato in a conventional electronic vacuum tube for radio receivers. Between the electrodes, there is still a back and a current flowing and a livelihood, the soaring is back and there is an ultraviolet light.Kogato strike phosphorus, ultraviolet light cara and shine brightly. The UV treatment of this absorber is almost equal to glass and phosphorus.

Startiraneto on the DLS is osiguryava from a special device - a starter, which for briefly applying voltage to the coil (for the circuit for switching on, we speak in a clear way). Tova e started partly on the device for control.

Starter for starter on DLS

You can, yes, sing the lamp and work (somehow se kazva "starter") at the beginning, for a short time, apply a high voltage to the electrode. Electronic ballasts work in exactly the same way, for which we speak in a casual way.

But the trace of the launcher on the LDS raises new problems: they light up the discharge in the crankcase, turning it into a discharge and instantly lead to a connection. For yes, to prevent this, tokt prez lampata in time for neinat, the work of the tryabva is limited. Tazi plays the role of this from another device - an electromagnetic ballast. The same regulatory part for the control device.

Electronic ballast for LDS with power 36 W

Taka without a starter lampata yama and a starter, burn out without a ballast. The complex from these two devices is a senarich ballast. Now, think, sort out what is necessary for ballast equipment and what you cannot do without it.

Important! The power to the throttle is a treb and the response to the power to the lamp. On the other hand, the case of lampata is disgusting, or it is already extinguished, or it is generally no more so, or it is still burnt out.

Scheme for connection to a fluorescent lamp

Now, in time, you will figure out how to svrzhete LDS kam throttle and starter.

Schematic connected to a single fluorescent lamp

How to work? Whenever you apply a voltage to the lamp, almost completely, it condescendingly, then apply the starter, ty katonyama current pres samata lamp.For the sake of the shining discharge, the bimetalate was in the starter, heating up and shutting down the verigata, giving a whole lot of tension to the coil of the coil. They shine a discharge into the starter from the gas, the bimetalate is cooling down and decoction of the verigata, but at the same time, heat up the spiral on the lampata. For the sake of reverse self-induction, the droselt forms a discharge with a high voltage (about 1 kV) and the fuse of the lamp.

Important! But the start did not happen, but the process was repeated on the starter. Probably, they were waiting for the old LDS, which “flashed” from the clock and could not fire it up.

Now the pressure on the starter is not enough, for yes, the light is on him and not participating in the work on the lampat. The ballast is included in the work, somehow limiting the current before the gas discharge device is given. Depend on the strength of the silat for the throttle. This is why it’s worse than the power on the throttle and the response to the power on the LDS. On the contrary, the case of current is more solid low or solid temple.

Clear illustration of working on a fluorescent lamp with a starter and an electromagnetic throttle

Nyakolko think about the capacitor at the entrance to the verigata. Imaiki golyama inductance, the consumer's ballast is not self-active, but also reactive energy, and the last one is ruined - for heating up the samiya drosel. The condenser, which is a kind of compensation for the capacitor, paints the consummation for reactive energy, increases the efficiency of the design and the boosters work on the throttle itself.

Is it possible for them to wield two LDS cams with a single throttle? Here, everything depends on the working voltage on the lamp itself. Ako sa projecting for a voltage of 220 V, then more shaking and bending the chain with two throttles, for sure, and bending two chains, which dadogh in a mountain.But if the lamp is designed for a voltage of 110 V, then it is completely possible.

The scheme is connected to two fluorescent lamps and a single throttle

The principle of working on a tazi veriga will remove any of the above, of course, the starter is dissuaded for a starter on its own LDS.

You can see the abbreviation EMPRA for throttling for home production. Such is the correct se naricha of electromagnet throttling - electromagnet ballast.

Zascho imate need from drosel vjv verigata

According to the principle of protection, we need from the chokes behind the lamps, open them: for yes, we will limit the current for work. Nie we know how everything is included. Let’s take a look at how and with how the means of limiting the current are, so we’ll talk about the device for the throttle and the principle of work is not enough.

The inductor in the electrical equipment of the se- richa winding wound on the core from one or another type. But so drosel with a frequency of 50 Hz and a relatively low inductance. For yes, increase the inductance by the inductors for fluorescent lamps, without yes, increase the size, behold, the magnetic chain is opened from the crawl, leaving small gaps between the planes on the plane.

Throttle for LDS - remove the inductor, but with the magnetic chain open

Protecting the throttle for current? Preminatively pres inductive winding, change the current of the magnetizir sartsevinat, storing magnetic energy in it. Pri tova with a single semi-full tya e is divided with a single sign, from a friend - from a friend. But for yes, save the energy with a different sign, first tryabva and “destroy” the previous ones: re-magnetize on the sartsevinata, for some reason, sort it out, “resist it” and not allowing it to direct the barzo. Poraditova is constantly converted to magnetization current is limited.

It is quite obvious that the chedrocell performs the same function in the AC of the verigata.

Advantages and disadvantages of electromagnetic throttles

Now we’ll talk for a while about predimstvata and lack. Offers for electromagnetic throttles include:

1. Relatively low price.
2. Simplicity in design.
3. Irritable.

Lack of equipment for this device, you see, a little more. That:

1. Golyamo warm and size.
2. A flashing lamp with a double light on the guard of the gate.
3. Bramchen.
4. Low efficiency due to high inductive resistance.
5. If the voltage is negative, the lamp may not be a starter.
6. Long starter (from 1 to 3 sec.).
7. When the lamp starts, it may take a “blink” for a long time, for some reason the spiral will burn out.

Is it possible without it

Poorly written, the drocelle is inseparable from the control device, which means that you cannot live without it. But the throttle is strangled. The name of the device, which limits the current on each other, is an electronic method. Those se call electronic ballast - Electronic Ballast.

ECG for fluorescent lamps

Somehow, from the diagram, printed on the housings on the device, it can also serve 4 LDS navigation, for starters they do not need a starter. Is it justified to change electronic ballast with electronic ballast? Parse it, a trace of electronic ballast:

1. Ima a little warm and size.
2. Don't bang.
3. Not predizvikva treptene to lampata from chestotata to mrejata.
4. Toy ima high efficiency (30-50% higher than tasi on EMPRA).
5. Starter LDS almost instantly.

Elektronniyat drosele is more complicated and more complex from electromagnetism, but the price is fully compensated for by negotiation.

Typical malfunctions - koso connection, pregryavane, open connection

And now we’ll look at the possible malfunctions on the electromagnetic throttles and we’ll also teach you how to check them (throttles). Nai-faults on the ECM:

1. Pregryavane. It is usually caused by incorrect operation (lighting is not ventilated or it is in a burning room), damage is in the distance from normal and a manufacturing defect (veryga from zavoi to zavoy).
2. Stupen winding… You may have been caused by overheating, mechanical damage or simply a manufacturing defect.
3. Zakrivane. You can be somewhere between the zava, so and pulna. Cause sa eat: marriage, pregryavane, mechanical damage.

How to check the electromagnetic throttle

Tova e forest yes be direct and not sa necessary measuring uredi. Sufficiently yes, just bend a simple chain exactly on the knee of the si, which will cut off the lamp from the pressurized chick, it is supported on the starter and is protected from the exhaustion of the pre-throttle:

Veriga for testvane on drosel

Important! The power for the lampate for feeding the trebva is approximately even equal to the power for feeding the throttles (ballast).

And so, sbiram verigata, including me. As a result, on Tova Vizhdame:

1. The lamp is off. Ima prekskvane on ballast.
2. Light with full brightness. Zakrivane.
3. Flash or burn. Ballast can even be worn.

Now leave the verigata and work for half an hour. Ako ballast se heating over 70 degrees Celsius, togawa nai -probably ima interobratno koso connection. Such is the device just yama yes starter LDS and which direction, then soon get out of it.

Such a conversation for electromagnetic throttles is an adventure. Now you know how you can thin and dory on your own and test it simply, but you need a smart device.
