I used a hair dryer at home, and suddenly it tripped all the way, and after the leakage switch was c

If there is no power. First, use the elimination method to rule out whether the household appliances are leaking, that is, unplug all the plugs and try to send the power once.

If the leakage can only be checked by an electrician instrument, first determine which line is leaking, or which two wires are short-circuited. The method is as follows, and the only way to check leakage is to use a resistance meter or a multimeter. The following tests are done.

Check the short-circuit live wire and neutral wire to measure the insulation resistance, check the grounding live wire to the ground wire insulation resistance, and check the neutral wire to the ground wire insulation resistance.

Knowing which line is leaking, we are using the segmented search method to gradually reduce the scope of the fault.

The fire wire or neutral wire of the hair dryer is poorly insulated to the ground (shell, ground wire) and leaks.

Summary. It's because one of the appliances you're using leaked electricity, so it tripped. The electrical appliance stops working, and the electric switch is pulled up to continue to be used.

It's because one of the appliances you're using leaked electricity, so it tripped. The electrical appliance stops working, and the electric switch is pulled up to continue to be used.

It's the switch of the light, and the appliances at home haven't been plugged in yet.

Xiaomi double-open single-control Zhi Li Zhongneng switch tripped and broke after about a month, and it was replaced with a new source oak that was tripped and broken in less than a month, and it was the same, controlling the kitchen and balcony, today I changed the ordinary bull, I tried it after I was safe, the total gate tripped, and it returned to normal after the hail disturbance, which is ** Something went wrong?

You try the appliances one by one.

What is the reason why my leakage switch tripped after a few minutes of pushing?

Hello explains that the circuit is faulty, and the common reasons are as follows: 1. It may be that the capacity of the total empty opening is too small, and the electrical current used has exceeded the rated current of the total empty opening, so it will trip, and the unnecessary electrical power supply will be unplugged. 2. If there is no load in the circuit, check the leakage protection switch, it is best to replace it with a new leakage protection switch, and then see if it is still tripped.

3. If the leakage protection switch is replaced or tripped, it means that it is a problem with the line, and it may be that the wire load of the circuit is too low, resulting in the instability of the circuit and has been tripping, and it is necessary to contact the electrician to overhaul the friendly circuit to see if there is a leakage problem. 4. Generally speaking, a small electric switch is a separate control of a room or a line, it is recommended to open the main gate to destroy, leave a road to open the switch, check in turn, and eliminate the fault.

The reasons for tripping can be the following:

1.The socket is incorrectly wired, which may cause tripping when used. This is usually the case when a newly installed socket, such as the neutral and ground wires are reversed. If the upper circuit breaker is a leakage protector, it will be judged as leakage tripping when it is used.

2.If there is a short circuit or leakage fault inside the electrical appliance, it will also trip when plugged into the outlet. The leakage protector plays the function of overload, short circuit and leakage protection. If the electrical appliance used has a short circuit or leakage fault, it will cause the circuit breaker to trip when it is used.

3.Overload tripping. For example, the circuit breaker of the branch is a 10A air switch, if the power of the electrical appliances on this branch exceeds it, the empty opening will overload and trip when it is used.

4.Leakage of power from the line of the socket branch. If there is leakage of the wire of the socket branch, the leakage protector does not trip because the leakage current of 30 mA is not reached, but after plugging in the electrical appliance, the current will change and trip immediately.

You can try it with a hair dryer with a little less power, and don't use electricity during the evening rush hour. If the line of the socket branch is leaking, use the shake meter to find the leakage line If the wire of the socket is too thin, and the power of the electrical appliance is too large, although it will not trip immediately, the wire will heat up and aggravate the aging of the insulation layer, which will cause a serious disaster.

1. The power of the line is not enough. Solution: Redesign the route.

2. Hair dryer circuit breaking. Method: Overhaul the hair dryer.

The power is not enough, is it in the student dormitory? If so, there is no way, power rationing; You can buy a smaller power one to try. If you are at home, the power of this socket is not enough, and you can replace it with another socket; It's also possible that your hair dryer has been short-circuited.

Hello, your problem is likely to be caused by the low insulation of the neutral line on the load side of the leakage protector.

If the live wire is grounded, it cannot be closed normally at all.

It is recommended to choose whether the switch is damaged, and connect the tripped route to other circuits to determine whether it is tripped caused by the unstable performance of the leakage protector itself. If it still trips, check the line insulation.

If it is leakage, it will trip immediately, which may be the cause of overload or aging of the protector. Generally, the current of the protector configuration is small.

If each lead is not firmly connected when you install the circuit, it will loosen after a long time of use, and eventually trip.

2. Load leakage.

The load leakage is similar to the above, but the load leakage will generally trip when the leakage is over. If the PZ30 distribution box is installed, there will be leakage inside, and the circuit will immediately cut off the power supply when leakage occurs.

3. The problem of empty opening.

When the air switch is working, if the current exceeds the range it can bear, the whole circuit will generally trip within a few minutes.

4. Short circuit of load line.

If the trip is caused by a short circuit in the overloaded line, then this phenomenon will generally trip within a few seconds after turning on the machine, and no power will be sent anyway.

5. Caused by large household appliances.

Due to the high power of large household appliances, the circuit tripping phenomenon occurs. In such a situation, it is necessary to re-transform the circuit, so that large household appliances can be routed separately and cannot be shared with other household appliances, so as to solve the phenomenon of circuit tripping.
