What's with the sudden power failure?

The reasons for the sudden power failure are as follows:

1, only my own home is out of power.

It may be that the power of household appliances is too large, which exceeds the carrying capacity of household lines, causing tripping; It may also be a short circuit of household appliances, such as aging lines and water ingress. There may also be arrears, as long as you pay, you can make a phone call. By the way, you can also use the reverse card to prepay the electricity bill for 10 yuan. Tips: After the power is cut off due to arrears, you should plug it back into the power supply before recharging, so as to avoid charging failure.

2, neighbors, or community power failure.

This reason is generally the failure of line equipment in the cell. At this time, the property electrician needs to focus on the inspection of key equipment such as distribution room, transformer and cable connector.

3, multiple communities or large-scale power outages

Regular physical examination of power grid equipment leads to power failure. According to the operation cycle and state evaluation results of power grid equipment, the power supply company carries out planned maintenance and overhaul of power outage equipment.

This kind of power outage will be reviewed and optimized in advance to reduce the power outage time and inform in advance. Power supply companies will also choose residents to go to work for maintenance, or choose ones with low electricity consumption, such as starting work in the early hours of the morning, so as to avoid affecting residents' electricity consumption.

Other circumstances of power failure.

Temporary shutdown: in case of line disconnection and other accidents, it is necessary to immediately cut off the power supply or cooperate with the government to carry out emergency rescue and other unforeseen projects; Power supply is "stuck in the neck" during peak hours, and an emergency power outage may occur.

Fault trip: if the rod is hit, disconnected, rod falls, tower falls, etc. due to bad weather, it needs urgent treatment; Or in the process of power generation and transmission, equipment failure may lead to unplanned failures and power outages.
