Why does one of the lamps in the lamp burn out and knock out the machine?

The machine knocks out when you turn on the light - reasons, what to do

If, when you turn on the light, the circuit breaker suddenly trips, then this indicates only one reason - a short circuit. If the problem does not disappear when replacing the light bulb, then you should look for the problem in the chandelier or lamp where it is installed.

Very often the lamp socket is faulty or the cable insulation is broken. In this article on the site we will look at the most basic reasons why the machine knocks out when the lights are turned on.

I call on the League of Electricians. (Thank you, you can downvote) =)

He turned on the light in the large room. A lamp in the chandelier burst (one of three). At the same time, the machine switched off.

Questions: 1) What is the cause and what is the effect? Did it short out somewhere and that's why the lamp exploded and knocked out the machine? Or did the lamp cause the machine to be knocked out?

2) Where to look for the problem - only in the chandelier and its connections or check all the wiring up to the panel? (The wiring is new, there were no problems before)

Side question. Small splinters on the carpet. 3) Does it make sense to clean and how? Or is it easier to just throw out the carpet?

PS Please don't leave negative comments. As soon as the rating is visible, I don’t ask for more than 5 pluses so that the fresh stuff doesn’t immediately disappear.

Light bulbs tend to _sometimes_ explode. I always turn away from them before turning them on for the first time, because... It is with the first that there is the greatest chance. (older fellow electricians taught me when I was young) There is most likely a metal base left in the socket, turn off the machine and unscrew it with pliers. Shine a flashlight inside and inspect the contacts for carbon deposits. Sometimes a light bulb fails precisely because it is not tightly pressed to the central contact: the light bulb is not screwed in enough (or the spring (they used to be under the central contact) has weakened, loose contact, heating, carbon deposits, which makes the contact even worse, etc.

I advise you to drag the carpet outside and beat it with a beater. (cover your eyes and breathing)

Morning summary. He took out the light bulb base. I did not find any traces of burning in the cartridge. He began to unscrew the second light bulb - the bulb remained in his hand, the base in the socket. (I found the name on the lamp - nifuya not Philipps, as I thought, someone installed Chinese shit)

I didn't find any traces in the cartridge. I have now installed new light bulbs. Good ones for sure. Now the light ticks quietly once every minute or two.

As I understand it, the base is heating up due to poor contact?

The light bulb shouldn't be ticking. Visually inspect the cartridges again. Check the contacts for burns and looseness. There are no miracles. Light bulbs, even branded ones, also have defects - production costs.

Well, as an option, you already have mania. Now you listen to everything and turn on the light.

Well, mania, yes. =)

“Yesterday the lamp broke” effect

+150 to hearing and attention.

It seems to have stopped ticking now. I've already taken it apart several times, sniffed everything, looked around, the contacts are all clean. I checked the connection points of the chandelier to the network. I checked the junction box, sniffed everything and looked through to the shield. Everything is clean everywhere. It seems to me that there were crappy lamps. And with a small jump they both jumped. One exploded. And the second was quietly and noiselessly dismantled onto the flask and base.

Tomorrow morning I’ll go see what’s wrong with the cartridge. Yes, it looks like metal.

We went over it with assembly tape, then with a vacuum cleaner. It’s good that he has a disposable bag, it’s not a shame to throw it away. There seems to be nothing left. But it's a little boring. Glass shards are a nasty thing.

That is, the short one in the socket is enough to screw up the lamp and knock out the shield?

In the wiring along the road from the shield to the chandelier, could there be some reason for the lamp exploding? I looked at the switch now, everything is clean, all connections are normal, there are no scorches anywhere, there is no burnt smell.

I was wrong about Philips. The light bulbs were crap. Now here's another problem(?)

Household appliance malfunction

After inspecting the sockets, it’s time for the distribution boxes. The wire connections in them must be of high quality, there must be no exposed parts, since they are the ones that can short-circuit.

Having finished inspecting the junction boxes, proceed to the lamps. A bad electrician may forget to check the chandelier when conducting such a study, and this can be a serious omission. Chandeliers are checked in the same way as sockets.

After you have inspected the sockets, light switches, distribution boxes and chandeliers, you need to start checking the electrical wiring. In most modern homes, electrical wiring is hidden, that is, hidden in the wall. To check it, you need to use a special device that accurately determines the location of the short circuit. However, only electricians usually have special equipment, and an ordinary person will have to be content with a multimeter. It may happen that with the help of it you will not be able to detect the “X” place, and then you should call a specialist with a thermal imager and other devices.

Saving electricity during a crisis

Entrance areas are being redecorated in apartment buildings. We are in the process of replacing lighting. We replace old lampshades with Chinese LED lamps. Various nuances occur from time to time. There is an example in my previous post. And here, this is how the apartment is powered from a common outlet.

How to clean a room

To eliminate metaphysical phenomena in the house, you will need to contact a person with psychic abilities. You can simply clean the room of accumulated negativity. Before this, you will need to free your thoughts from the bad. If all day long you think only about problems and remember the bad, then a person will emit negative energy, as a result of which people will stop communicating with him, his performance will decrease, and objects around him will begin to break. Using the technique of positive thinking, a person can free himself from bad thoughts, and problems will go away with them.

Aroma oils

Relaxing your whole body will help you get into a good mood:

• light a candle;
• add a couple of drops of soothing aroma oil, lavender or tea tree are perfect;
• turn on relaxing music;
• think about your best memory and try to mentally transport yourself to that moment;

By doing the procedure a couple of times a week, you will see a positive effect.

With candles

Often burning out lamps are a sign of a strong accumulation of negative, mystical energy. A person may enter the house who is jealous of the family and even causes damage.

To cleanse your home of damage and accumulated negative energy, you should perform a ritual with candles. You will need:

• as many candles as there are rooms in the apartment, including the bathroom;
• separate candle;
• Holy water.

Early in the morning you need to get up, wash your face with cold water 3 times and read the prayer: “Our Father.” In each room, in the most visible place, place one candle and light them. Place a container with holy water in a visible place.

With a separately lit candle, you need to go around all the corners in the house 7 times, each time schematically draw a cross, and approach the front door. The entire cleansing ritual is to pronounce the words:

If there is a negative influence in any of the rooms, the candle will go out and smoke heavily. Upon completion, place the candle in the corridor, wait until all the candles burn out, and then throw away the remaining wax. Sprinkle all the corners in your home with holy water, especially carefully in the room where the candle went out.

Immediately after cleaning, you will notice how it becomes easier to breathe in the room. The lights will stop blinking, your affairs will be in order.

Power Supply Polarity Determination

It happens that you have a DC power source (mobile phone charger, power supply, two powered ends on a car) and you don’t know which one is plus and minus, but you need to find out. There is neither a device at hand to find out, nor a diagram.

And here ordinary raw potatoes will help us. We cut the potato in half and stick two powered wires into it next to each other. The wire around which white foam

This is
a minus
, and where around the wiring
turns blue
is
a plus
.

Note:

the lower the voltage, the closer the wiring should be to each other.

How to protect yourself from a second explosion

If you follow the operating conditions, and also know how to correctly select products of the required power, taking into account the lighting scheme, they will rarely burst. Therefore, you won’t have to spend a long time figuring out why the light bulbs in the chandelier explode. But there remains one more reason that is difficult to control. These are voltage drops.

Relay for voltage control.

To protect yourself from such situations, you can purchase a voltage control relay, which is installed in the panel and automatically adjusts the indicator. If there is free space, it can be easily installed on the DIN rail of the indoor switchboard.

Main causes of burnout

The reasons can be different - from power surges, poor-quality contacts in the electrical circuit to frequent switching on/off of devices, high temperatures, and vibrations.

Power surges

The industrial voltage is 220 V. If the actual value exceeds the required value, the tungsten filament overheats significantly, which shortens its service life.

A multimeter is used to check the voltage. Measure the value two to three times a day, since jumps are possible during a certain period. For example, this happens in the evenings, when people return from work or businesses connect to the electrical network at home. Another sign of high voltage is that parallel to the burnout of the light bulbs, the plugs and circuit breakers are knocked out.

If you detect power surges in the network, proceed as follows:

• buy lamps designed for higher voltage - for 230 - 240 V (look for the value on the packaging or on the base of the product);

additionally install protective blocks for incandescent lamps on each switch (protect against overvoltage, ensure smooth switching);

• use a stabilizer installed in the first distribution box of the apartment (protects electrical appliances in the house);
• buy fluorescent lamps that are not affected by power surges;
• use LED products.

Important! Knocking out traffic jams and machines is not always associated with increased voltage. This also happens in cases where the total power of electrical appliances connected to the network exceeds the permissible limit. Don't forget to short circuit the electrical wiring.

Poor quality contacts in the socket

Old domestic lamps used plastic sockets, and the cheaper the product, the lower the quality of the material itself. Ceramic cartridges are better, but are used less often. These lamps are designed for light bulbs up to 40 W. If you take a 60 W lamp, over time the socket will begin to crack. This will lead to oxidation and burning of the contacts. Poor contacts are another reason for the lamp to overheat and burn out.

If the light bulbs constantly burn out in one lighting fixture, and when the light is on, you hear extraneous sounds with a change in brightness, look for the cause in poor-quality contacts on the sockets. Clean them, replace burnt cartridges or the entire lamp. Avoid using devices with lamps of higher power than indicated in the lamp data sheet.

If the conditions are met, there is not enough light, switch to using luminescent products. Most modern lighting devices set an important requirement on the sockets - the power of the lamps used is not higher than 40 V. There is no need to limit the luminous flux and illumination of the room - it is possible to use fluorescent lamps.

Correct wire connection

The next reason is a wiring fault. Check the connections inside the electrical panel and tighten the screws that are responsible for securely fastening the cables.

If plugs and circuit breakers are knocked out when a light bulb burns out, be sure to check the compliance of the power of electrical appliances in the house with the electricity consumed. If a malfunction or insufficient power parameters are detected, the identified products must be replaced.

Examine the connections in each junction box of the apartment (private house). Pay attention to blackened wires and melted areas. Clean such contacts and tighten loose connections. Be sure to replace twisted wires with high-quality connectors.

Avoid galvanic pairs, when two or more cables of different metals are connected by twisting. In such areas, severe overheating occurs. If such cases cannot be avoided, use pads.

Problem switch

The next step is to check the switches. If such an element does not work correctly, incandescent lamps may also burn out. Disassemble and inspect the condition of the contact elements. If you notice sparks, carbon deposits on the contacts, or traces of blackness on the wires clamped with screws, get rid of the switch and install a new one.

If light bulbs turned on by one button burn out, do not disassemble the switch. Replace with a new one, additionally install a dimmer that provides smooth switching and the ability to change brightness.

Switches vary in terms of service life - replace the electrical product in a timely manner.

Poor quality lamp

Incandescent lamps from domestic manufacturers are significantly inferior in quality to their foreign counterparts. Lamps with a power of up to 60 W, most often used in everyday life, burn out. If previously domestic products were better in price, now their cost is comparable to devices from Osram and Philips factories. In this case, give preference to the latter group.

There are various recommendations for choosing lamps, but before you run to the store for foreign analogues, make sure that they are the problem.

Frequent activation

When turned off, the tungsten filament is cold, which is why its resistance is lower than that of the lamp when it is on (with a heated filament). When switched on, the current flowing through the electrical product is significantly higher. If frequent switching on/off occurs, the starting current will lead to rapid evaporation and breaking of the filament.

Vibration and mechanical stress

Constant vibrations, shocks and other mechanical impacts lead to rapid burnout of incandescent lamps. The way out of the situation is to replace conventional products with LED or compact fluorescent ones.

How does a light bulb work?

First of all, you need to understand how light bulbs function. You can consider their operating principle using the example of an incandescent lamp. The current passes through a thin spiral made of tungsten. The melting point of this metal is quite high. Tungsten filament can heat up to 2500°. When the coil gets hot, it emits light.

Inside the flask is filled with gas, such as argon or a mixture of gases. Under its pressure, the rate of destruction of the tungsten filament decreases. But still, over time, it breaks down into small particles. Then weak spots appear on the conductor where it can break.

In gas-discharge lamps, the gas inside the bulb glows. The glow occurs under the influence of an electric charge.

Why do halogen lamps burn out?

Halogen lamps are rarely used in household appliances. These are mainly spotlights, less often chandeliers. One of the main reasons for failure is contact with bare hands, which leads to grease stains on the surface. The products overheat significantly, which causes the flask to collapse.

Use clean gloves during installation. If dirt is found, remove it with an alcohol-soaked cloth. Halogen lamps can burn out due to technically incorrect installation of electrical wiring going to the place where the spotlight is used.

Features of the circuit breaker

To understand the reasons for the operation of a circuit breaker, you must first answer the question of what this device is for and what functions it performs. Features of AV operation are as follows:

• The main task of the device is to protect electrical wiring and household appliances connected to it from too powerful a current that occurs for various reasons.
• The device is mounted on a phase circuit, the rupture of which occurs when the packager is disconnected. If the machine has two or more poles, then when it is triggered, the zero circuit will also open.

• The AV can de-energize the network both when switched off manually and when an emergency occurs, which can lead to damage to circuit elements.

Recommendations for extending the life of incandescent lamps

The service life of light bulbs depends on the correct construction of the electrical wiring, the device used, power surges, mechanical shocks, temperature and the switch.

Prolonged operation of the product leads to overheating of the tungsten filament and its gradual evaporation. Because of this, the diameter decreases and the thread sooner or later burns out (breaks). The higher the heating temperature of the tungsten filament, the brighter the glow will be, characterized by a faster evaporation process and a shorter service life.

On average, the lamp is designed to operate for 1000 hours. After approximately 750 hours, the luminous flux decreases by 15%.

A slight increase in network voltage (about 5%) reduces the service life by half. This can be verified by observing lighting products installed on staircase landings, which constantly operate at night, when there is minimal load on the electrical network, which leads to an increase in voltage.

Since the tungsten filament is very cool when turned off, it is advisable to warm it up with a lower current before turning on the incandescent lamp at full power. To do this, install dimmers.

Rated voltage

Modern products do not indicate a specific voltage, but a certain range - from 215 to 225, 230 to 240 V. If the lamp is operated within this range, good luminous flux and durability are ensured.

This approach of manufacturers is associated with the difference in operating voltage of the network in its different sections. Near the source (substation) it will be higher than far from it. For this reason, you need to select light bulbs in accordance with the apartment’s network voltage. Measure it with a multimeter and if it turns out that the parameter is 230 V, buy incandescent lamps with a range from 30 to 240 V.

Checking the cartridge

If lamps in the same socket burn out frequently, check its operating temperature. If it is hot, disassemble the product, clean and bend the central and side contacts, and then tighten the wires going to the cartridge. If light bulbs in a chandelier often burn out, try using products of the same power.

Application of a protective diode

Recently, electricians have been using diodes installed in front of incandescent lamps on staircase landings. The quality of the voltage does not decrease, and the service life increases. If you connect a resistor in series with the diode, the light bulb will last for many years.

Warning!

But let us remember firmly: without the qualifications and skills of an electrician, without special tools and protective equipment, it is impossible to carry out work on ANY electrical equipment, including household electrical appliances! You can only use the standard controls without disassembling anything.

Electric shock will not warn you in advance, and its consequences are unpredictable and can be long-lasting. Especially if you have been drinking alcohol. Already from a shot of vodka, a person’s electrical resistance drops 1000 times, and an otherwise harmless pinch can turn out to be a fatal blow.

How to get rid of negativity

Periodically, every home requires cleaning for the following reasons:

• too much human energy accumulates;
• negative thoughts of family members;
• frequent quarrels;
• the negativity accumulated over the years does not allow you to advance in your career or studies;
• the family’s financial situation suffers;
• Frequent illnesses due to problems with electricity may indicate a magical influence on your family.

Loneliness and an urgent need for communication, melancholy can affect the general atmosphere of the house, which is why light bulbs can often burn out. To stop suffering from loneliness, you can get yourself a pet.
