What is the cause of the tripping of the leakage switch?

Four reasons. 1. Poor installation of leakage protector If the terminal connection of the leakage protector is not firm during installation, the terminal will heat up and oxidize over time, and the wire insulation layer will be burned out, accompanied by the smell of ignition and rubber and plastic burning, which will cause the circuit to undervoltage and trip the leakage protector. Second, there is a problem with the leakage protector itself.

When purchasing leakage protectors, users should try to buy them from reputable designated manufacturers or stores. Don't buy some self-employed "three no" leakage protectors, often the gains outweigh the losses. Three.

With the popularity of household appliances, the load current of many families has far exceeded the rated current of the leakage protector on the line, resulting in the tripping of the leakage protector. This usually happens in the use of high-power household appliances such as air conditioners, electric kettles, etc. Generally, only a matching leakage protector can solve the problem.

4.If the leakage protector trips due to leakage or short circuit of the load such as household appliances, as long as the faulty household appliances are unplugged, the power can be re-transmitted; If the line leaks or short-circuits, it is more difficult. You can solve some simple faults first, so that some lines can temporarily resume power transmission.

Leakage switch tripping generally has the following reasons: 1It is best to find an expert to check the leakage switch, if there is a fault, it must be replaced with a new one, which is the most important protection for residential electricity, do not be careless; 2.

If there is no problem with the leakage switch after inspection, and it always trips, it means that there is a grounding point in your electrical circuit or electrical appliance in your home, and it has nothing to do with electricity consumption; 3.If it trips as soon as the light is turned on, my personal analysis is that if it is not a leakage switch, it is very likely that the neutral line in your home circuit is damaged or other reasons cause a grounding point. It is advisable to find an electrician to check the neutral line.

It is recommended to find a professional master to take a look, if you are not an expert, it will not be safe.

Hello. Schneider leakage switch selection FAQ:

1. After tripping, first remove the power cord of the air conditioner from the leakage protection switch, test the power supply voltage of the input leakage protection switch, if it is normal, close the reset switch, and still trip in the case of no load, it is the internal fault of the leakage protection switch, if it does not look at the switch, it is a problem with the electrical appliance.

2. The leakage protection switch trips due to the small switching capacity, the wires are not connected, the electrical appliances are overloaded, and the ambient temperature is too high.

3. The principle of replacing the leakage protection switch after the fault is not less than the original parameter, and the leakage current cannot be greater than the original parameter. 4.The fastening screws of the secondary lead-out line of the zero sequence transformer are loose or desoldered.

5.The manifold SF is damaged internally. 6.

The printed circuit board has false soldering or poor contact with the connecting plugs. Hope it helps.

1. What is the reason for the tripping of the leakage switch?

1.Circuit breaker overload: This problem occurs when the circuit fails to match the circuit breaker after the circuit is replaced.

2.Installation of circuit breakers: When installing circuit breakers, loose connection points or poor contact will lead to tripping.

3.Leakage electrical equipment: If the electrical products used in the home have leakage, the leakage switch will trip.

In addition to the above possibilities, there are other factors that can also cause the leakage switch to trip. For example, in the process of wiring, if the line is connected incorrectly, the leakage switch will trip. When the product is short-circuited, it is likely to generate heat, burn out or melt the power connection, and also cause the leakage switch to trip.

Another possibility is that the current voltage situation is not particularly stable. For example, if the voltage is too low or too high, it may also cause the leakage switch to form a protective function, so it will trip.

Leakage switch is an indispensable electrical component in the family, which provides a guarantee for people's safety, but sometimes frequent tripping brings a lot of trouble to people. So, what are the reasons for the tripping of leakage switches? Let's take a look.

Leakage switch is an indispensable electrical component in the family, which provides a guarantee for people's safety, but sometimes frequent tripping brings a lot of trouble to people. So, what are the reasons for the tripping of leakage switches? Let's take a look.

1. Poor installation: The lead wire of each pile head is not firmly connected and loosened for a long time, which will cause the pile hair to heat and oxidize, burn out the insulation outside the wire, and emit sparks and burnt smell, resulting in undervoltage of the line and air switch action.

2. The leakage switch does not match the load: the actual electrical load of the household is greater than the rated current of the low-voltage circuit breaker on the line. It generally occurs after the installation or addition of high-power household appliances such as air conditioners and electric water heaters. The matching air switch must be replaced.

3. Leakage and short circuit of electrical appliances or lines: When it is found that the electrical appliances used are leaking, as long as you unplug the electrical appliances with leakage faults, and then close the low-voltage circuit breaker again, you can send power. If a leakage or short circuit is found in the line, an electrician must be called to deal with it.

4. The incoming voltage of the power supply is too high: this is dangerous, and it generally occurs in residential buildings with three-phase four-wire power supply. Do not forcibly close the low-voltage circuit breaker, otherwise it will burn out the electrical appliances at least and cause a fire at worst.

5. There is a problem with the quality of the leakage circuit breaker: check the quality of the leakage circuit breaker first. One is to check the leakage tripper, generally with the test button to test, when pressing the test button, because of the I1 shunt, so that I1 and I2 are not equal, that is, the phasor sum is not zero, therefore, the leakage circuit breaker should act, requiring the trip sensitive; The second is to check whether the leakage circuit breaker can be closed in the no-load state, if it cannot be closed, the leakage circuit breaker is faulty, can not be used, and should be replaced (self-repair is not recommended).

6. Leakage circuit breaker wiring error: check whether the phase wire of a certain electrical equipment is connected to the front of the leakage circuit breaker, so that part of the load does not pass through the leakage circuit breaker, so that the N line current of the leakage circuit breaker is greater than the phase current, so that it trips, or even cannot close the switch.

7. Leakage of electrical equipment: At this time, the metal shell of the equipment is live, and the electric tester can be used to check and find out the fault.

8. The N line and PE line on the socket are reversed: if they are reversed, a zero sequence current will be formed, which will cause the action of the leakage circuit breaker.

9. The n line of a certain lamp in the lighting circuit is taken from the socket circuit: modern housing has been multi-circuit power supply, lighting and socket power supply are separated, the lighting circuit is controlled by a circuit breaker, and the socket is controlled by a leakage circuit breaker.

10. The line trips due to leakage caused by moisture: check the junction box in the kitchen and bathroom lines. Open the damp junction box, the street inside is wet, there are water droplets covering it, and individual nozzles are dripping, which is caused by the damage of the upper waterproof layer and water seeping into the pipeline.

The above is the relevant knowledge of the reasons for the tripping of leakage switches. With the above knowledge, some small problems can be eliminated by yourself, and some necessary troubles can be saved.

Hello. Dear, this simple is caused by leakage caused by the line The main switch of the distribution box is a 250A leakage switch.

The following are the total open leakage switch of the machine room, the total open air of the LED screen, the total leakage of the air conditioner, and the total open of the lighting leakage. The problem is that the switch in the computer room sometimes trips when the LED screen is turned on, and there is no problem with other switches. When the LED screen switch is turned off, the switch in the computer room will not trip.

There is only a network cable between the computer room and the LED screen.

Hello. Dear, the LED screen line is short-circuited.

The LED screen and the machine room are two switches respectively.

If there is a problem with the LED screen, it should also be a total open 250A total trip, not a computer room trip.

Hello. Dear, you said that the power of the LED screen will not trip

Electric era so far, electricity to help people is obvious to all, people's production and life in all aspects need to use electricity, electricity to provide us with convenience at the same time, there are also certain safety hazards, I believe that we have more or less experienced some electrical accidents, light damage to the circuit, heavy disaster accidents, etc., so in the family, a variety of industrial circuits will be equipped with leakage protection switches, so what are the reasons for the tripping of leakage switches? Let's take a look with Qeeka Home experts.

1. What are the reasons for the tripping of the leakage switch?

The reason for the tripping of the leakage switch is that the circuit breaker model is not properly selected, the circuit is overloaded, the wiring is wrong, the voltage is too low or too high, no matter which reason is worth paying attention to, the leakage switch tripping indicates that there are certain safety hazards in the use of electricity, and it is very likely that there will be electric shock, electrical burning, fire and other problems, which need to be dealt with and repaired in time. Traces of acres.

2. Household electricity safety precautions.

1. Avoid turning on electrical appliances for a long time.

It is best not to turn on the electrical appliances in the home for a long time, because after a long period of use, the electrical appliances will be heated, which will burn out the electrical appliances, or cause the aging of the electrical circuits, which will cause potential safety hazards, etc., except for special appliances such as refrigerators, other TVs, air conditioners and other electrical appliances can not be turned on for a long time.

2. Timely maintenance.

Once the household appliance or circuit fails, you must find a professional to repair, and the maintenance should be timely, so as to avoid greater hidden dangers if you delay the time.

3. Do not touch the power supply when your hands are wet.

If you have just washed your hands, you must not touch the power supply, including plugging and unplugging, turning on or off electrical switches, etc., because wet hands are easy to get electrocuted, especially when using electrical appliances in the kitchen and bathroom.
