How can the leakage protector leakage not trip?

The following reasons will make:Leakage protectorNo tripping:

1. The neutral wire produces repeated grounding.

, it will cause the leakage protector to cause shunt rejection, and the neutral repeat grounding point is difficult to find.

2. When the power supply is out of phase, and the missing phase happens to be the working power supply of the leakage protector, there will be rejection.

From the above analysis, it can be seen that the frequency and rejection problems of the leakage protector in actual use are not only due to the objective environment and management, but also the technical misunderstanding of the leakage protector itself.

The leakage protector can be used to protect the equipment from electric shock in the event of leakage failure and the fatal danger of personal shock, with overload and short-circuit protection functions, which can be used to protect the overload and short circuit of the line or motor, and can also be used as an infrequent conversion and start of the line under normal circumstances.

Leakage protector can be classified according to its protection function, structural characteristics, installation mode, operation mode, number of poles and wires, action sensitivity, etc., here it is mainly described according to its protection function and use, and can generally be divided into leakage protection relay and leakage protection switch.

and leakage protection sockets.

Open the leakage protector and cut any of the leakage current detection coil or tripping coil wires of the leakage protector.

That is to say, there are two coils inside, and you can cut any one of the wires at will).

It's easy to destroy a leakage protector, but if you think it's worth it, do you think it's worth it?

On the surface, you seem to have solved the problem of leakage switch not tripping, but in fact, the consequences are endless, once an electric shock accident occurs, you will regret it, the fundamental solution is to seek the help of an electrician to thoroughly find out the cause of the leakage protector malfunction and repair it.

Only with the safe use of electricity can life be guaranteed.

If the leakage does not jump, then there is no need for the leakage switch, and it is directly connected to the knife switch, so that the leakage does not jump.

Summary. The main reasons are as follows:

1. The switch is overloaded, and the rated current of the switch is not matched.

2. The fire wire on the load side of the switch is grounded, and the neutral line on the load side of the leakage switch is grounded, which will also cause tripping.

3. The switch is damaged or the electrical grounding is short-circuited, whether the neutral line on the load side is mixed with the neutral line of other circuits, and the line insulation is too low.

When the leakage protector uses electricity, it does not trip, but when it does not use electricity, it trips.

The main reasons are as follows: 1. The switch is overloaded, and the switch rating is mismatched in the selection of the fiber current. 2. The live wire on the load side of the switch is grounded, and the zero wire on the load side of the switch is grounded in the leakage cavity, which will also cause tripping.

3. The switch is damaged or the electrical grounding is short-circuited, whether the zero line on the load side is mixed with the zero line of other circuits, and the line insulation is too low.

The leakage switch cannot be closed normally Check the method: 1. Check whether the reset difference button of the leakage switch is reset. After pressing the reset button, it can be closed normally.

2. Check whether the wiring of the leakage switch is correct. incorrect and rewired. 3. Check the insulation of the line on the load side of the leakage switch, if the short circuit refers to the grounding, it is necessary to eliminate the fault before it can be closed normally.

The use of the hair dryer for cooking and boiling water is normal, and it trips after turning on the light for a while at night.

Is your lamp burning?

The circuit breaker (air Jingda ridge switch) is used for a period of time to trip, and it is generally considered that the power of electricity is greater than the rated power of the circuit breaker and the overload causes bright seepage, but the circuit breaker does not trip, it should be that the circuit breaker itself is faulty. 2. Solution to overload 1. Confirm whether it is caused by the failure of the circuit breaker, which cannot be operated and the power supply is disconnected, and consider replacing the circuit breaker; 1. Purchase reliable quality switches, sockets, circuit breaker light switchgear; 2. Select a circuit breaker or related equipment with sufficient rated power in combination with the wires deployed; 3. Rational use of household appliances, try to avoid high-power electrical appliances running at the same time; 4. If necessary, the existing lines can be optimized and household appliances can be reasonably allocated.

There was a light tube that really didn't come on, and then it didn't work and didn't repair.

That's the problem with the tube.

Kiss. <>

I need to fix it.

The lamp has been removed.

It won't trip for no reason.

You can call the master to repair it.

Oh. <>

Summary. Hello, you can't do it that way.

Reason: Let the experimental button be used normally, then it must be tripped, if it is not tripped, then the leakage switch will be replaced, this is the role of the button.

There is also a way to make the button invalid, open the circuit breaker, and remove the transformer, so that the button will not trip when pressed, but also in the future.

Never have to trip again.

Note: Please refer to the operation according to the actual situation, absolutely do not approve of this operation, if the lower equipment does not allow short current, then it is necessary to coordinate with the user unit to carry out regular inspections, and there is no problem with the regular inspection of electrical equipment.

You are only good, you can't operate like this reason: let the experimental button use normally, then it must trip, if it does not trip, then the leakage switch will be replaced, this is the role of the button. There is also a way to make the button fail, open the circuit breaker and remove the transformer, so that the button will not trip when pressed, but it will never trip in the future.

Note: Please refer to the empty operation of the stool according to the actual situation, absolutely do not approve of this operation, if the lower mouth equipment does not allow short electricity, then it is necessary to coordinate with the user unit to conduct regular inspections, and the regular inspection of electrical equipment is no problem.

Several situations in which the "leakage protection switch" does not trip when the human body is electrocuted:

1. The person stood on an insulated wooden bench and touched the fire wire with one hand and the zero line with the other. In this case, there will definitely be an electric shock, but the leakage protector will not trip, because the human body does not touch the earth and does not produce leakage.

2. If a person stands on the ground and one hand touches the line of fire, the person will be electrocuted. If the leakage current does not reach 30 mA, the leakage protection will not trip, and the minimum leakage protection starting current in our household is 30 mA. Because most shoes are insulated, but the insulation effect is not very good, so the hand touches the fire wire and has the feeling of electric shock, but the leakage current does not reach the jumping standard, in this case people can break free.

3. If the wiring at the upper end of this 1P+N leakage guarantee is wrong, the leakage guarantee will not trip. Because the n position of this leakage is not on/off, it is also open even if it trips up and down n points.

4. The leakage warranty will definitely not trip if it fails or is broken, and the quality of the leakage warranty can be judged by a simple test. In the case of power-on, press the yellow test button, if it trips, it means that the leakage is intact, if it does not trip, it must be replaced even if it is replaced, so it is very necessary to press it once a month.

Hello, the installation of the leakage protector does not trip if it is electrocuted, first, the leakage protector is damaged.

Second, the resistance of the human body is relatively large, and the leakage current cannot reach the action value of the leakage protector.

The leakage current of the household leakage protector is 30mA. As long as the leakage current reaches 30mA, the leakage switch will operate immediately.

30ma=。

When an electric shock occurs, how many ohms does the resistance exceed the leakage switch will not trip, the calculation is:

30mA = ohms.

The above calculation is the maximum value, beyond this resistance, the leakage protector will not trip in the event of an electric shock.

A leakage protector is installed at home, why people will not trip if they are electrocuted, these 3 points can not be sloppy!

It's broken, or it doesn't exceed the rating.

Or maybe it's too damp in a certain location.

Hello, dear <>

Leakage protector is used to protect personal safety of electrical appliances, if the leakage protector leakage does not trip, there may be the following situations: leakage protector is not properly set: the leakage protector of the rated orange blind current, rated voltage and sensitivity and other parameters need to be set correctly, if set improperly, may lead to leakage not tripped.

You can check if the settings of the leakage protector are correct. The leakage current is too small: the rated current of the leakage protector needs to match the rated current of the equipment that is blind to electricity, if the leakage current is too small, it may cause the leakage to not trip.

You can try replacing the leakage protector with a higher current rating. Leakage of electricity in the electrical equipment itself: If there is leakage in the electrical equipment itself, the leakage protector may not be able to detect the leakage current in time.

It is recommended that you check whether there is leakage of electrical equipment, and repair or replace it in time. Leakage protector failure: If none of the above problems exist, the leakage protector itself may be faulty, and it is necessary to replace the leakage protector or contact professional maintenance personnel for maintenance.
