1, overload, air switch tripped.
If the indoor power supply is restored after closing the brake, but it trips again after a few minutes, you can turn off some high-power appliances and see if it will trip. If there is no trip, it means that the indoor load has exceeded the threshold range. When this happens, it is necessary to replace the high-current idle switch.
2. The zero line is burnt out
If the indoor lamp has electricity, the socket has no electricity and the leakage protector has not tripped, it is likely that the indoor neutral bar has failed. In this case, just replace it with a new one.
3. Circuit problems
If the home can't be pushed up after tripping, you need to unplug all the sockets in the room and check which electrical appliance is short-circuited one by one. First, turn off all air switches and push them up one by one in sequence. If any air switch trips immediately after being pushed up, it means that the electrical appliance is short-circuited and can be repaired.
You can choose to replace the air switch or repair the power cord. Because the local power failure at home is caused by the damage or tripping of a branch switch, it is necessary to check whether the switch of each branch has the above two phenomena and repair it in time.
Emergency measures for power failure:
1. In case of power failure, lighting tools such as flashlights should be used. First, check whether the internal distribution switch and leakage protector trip.
2. If there is burning smell, smoke and discharge in the room, all power supplies should be cut off immediately to avoid fire.
3, fuse blown, should be replaced in time, but can't use copper, iron, aluminum wire instead.
4. Emergency lighting sources, such as candles and flashlights, should be provided indoors and placed in a fixed position.
5, wire aging is easy to cause power outages, should report to the relevant departments as soon as possible to replace.
6. If it is found that the power outage is not caused by indoor reasons, contact the property management personnel in time.
