What is the reason for the sudden power failure at home?

1. The power supply line suddenly lost power.

The power generated by power plants reaches many links in users' homes through transmission lines, power conversion and distribution stations. Any link that breaks down, is damaged by external forces, or encounters irresistible natural disasters will cause power outages. If there is a large-scale power outage suddenly, it is likely that the power outage is caused by a sudden line failure. Customers can inquire through the "95598" automatic inquiry function.

2. Arrears and power outages

If the customer fails to pay in time within the prescribed payment period, the relevant departments will take power-off measures according to relevant basis. The customer needs to go to the bank to settle the electricity bill and ask for it in time, and then notify the contact person according to the contact number provided on the arrears notice, and the power supply can be resumed after completing the relevant procedures.

3. Low-voltage fault power failure

Some people increase electrical equipment privately, and use excess capacity to cause electrical components such as transformers, switches and watt-hour meters to burn out. The failure of internal equipment such as master brake and switch brake, the disconnection of internal lines in the building and the tripping of air switch will all cause power failure.

What if the power goes out?

The first step is to observe whether there is a power failure in the neighboring houses. (1) If it is completely black, the power is out. You just need to find a candle or flashlight, play with your mobile phone and wait for the call. (2) If it is a family problem, it is a family problem. )

Step two, find the flashlight, turn it on and go to the distribution box at home. (Every household has its own distribution box. (1) In rural areas, it should be fuses and small air switch, also called protectors. At the entrance of every household, there is a white plastic box. ② Small thermal protection circuit breakers used in cities are mostly installed near the entrance. It is a rectangular plastic panel with many small switches inside. )

Step 3, observe whether the switch is tripped or disconnected. (1) In rural areas, we should first observe whether the fuse is blown, and never touch it with your hands. If it doesn't blow, observe whether the small wrench on the protective sleeve next to it is facing up. If it is in the middle, it means it has tripped. Let's pull the small wrench to the bottom first. (2) In the city, because it is observed whether the small circuit breaker is on or not, the wrench is open down, and it may jump up, so it should be pulled down)

Step 4: Don't switch on in a hurry, first check what caused the trip, eliminate the reason, turn off all electrical appliances and disconnect the power supply. If you really don't know how to do it, please contact me. I'm Lei Feng! ! )

Step 5, after eliminating the cause, go back to the distribution box and turn on the switch, then wait for one minute, pay attention to see, listen and smell (see: whether the fuse is red or not, whether there is a spark at the switch. Listen: Is there a buzz or buzz? Smell: Does it smell of burning? )
