When it rains, there is always a power outage. Will it thunder and rain?

The high-voltage line was struck by lightning protection.

About lightning protection tripping of high-voltage transmission lines: when high-voltage transmission lines are struck by lightning, overvoltage will occur, which will lead to insulation flashover. Although lightning rods are installed in substations and towers, lightning arresters and lightning wires are also installed on lines, lightning may still cause protective tripping of power equipment protection devices.

The high-voltage line was struck by lightning protection.

It is more common that the high-voltage line loses voltage instantly when it thunders, and the power supply is restored after the lines overlap. We often see lights flashing or computers suddenly restarting, which are all caused by the above reasons. There are also cases where insulators and other devices are damaged by lightning and must be replaced before power transmission is resumed, which requires a long repair process.

Protection of residents' low-voltage electrical equipment

When the peak current or voltage is suddenly generated in the electric circuit or communication circuit due to external interference, the surge protector can shunt in a very short time, thus avoiding the damage of surge to other devices in the circuit. At the same time, for the safety of people and household appliances, it is recommended to turn off the power supply and appliances when it thunders.

Emergency repair of power supply in lightning disaster weather

Power supply emergency repair in lightning disaster weather: In thunderstorm and windy weather, some trees, billboards and other sundries are easily blown down (lifted away) by strong winds, damaging or winding power equipment, resulting in short circuit tripping of lines, and power supply dispatching in Huazhou is also needed ... Don't panic when power is cut off. Calmly inform the exact location, fault phenomenon, contact number and wait for the call.

How to avoid being injured by Lei Gong Dian Mu! Lightning disaster has been listed as one of the "Top Ten Serious Natural Disasters" by the United Nations and called "a major public hazard in the electronic age" by the relevant departments of China. According to the statistics of China International Lightning Protection Forum, there are 3,000 to 4,000 casualties caused by lightning strikes in China every year. The secret of lightning protection and electric injury: three customs and three avoidance. (Turn off the electricity, windows and mobile phones; Avoid water, heights and metals)

Lightning disaster weather

What are the electric workers doing?

As a state-owned public service enterprise, electric power companies not only provide goods-electric energy like department stores, but also bear social responsibilities. Whether it's thunder, rain, strong wind, or "knives" falling from the sky, electric power employees are sticking to their posts. In order to reduce the impact of severe weather, some employees plan and give orders in the dispatching control center, some employees closely monitor and prepare for switching operation in the substation, some employees are responsible for answering emergency calls until their ears are hot, and some employees troubleshoot in mountains, trees and back streets. This is also the hardest power repair, brother.

Why is there a power outage in thunderstorm weather?

In the past few days, Huazhou has fully launched the summer mode of "high temperature+thunderstorm". Some friends want to ask, why is there a power outage when it is windy and rainy?

I can only stay at home in rainy days, and the power failure, especially at night, is really inconvenient and a little scary. This small series is particularly understandable. However, don't get angry in a hurry. Bian Xiao also wants to tell you why it's easy to lose power in rainy days.

In the storm, branches and large pieces of plastic sheets are flying all over the sky, which are easy to hang on the wires, resulting in line tripping and power failure. Trees may be blown off or blown down in bad weather, and trees that are usually at peace with wires will also become "killers" of the power grid, leading to power outages, disconnection and even broken poles.

When can my family make a phone call in the storm?

Due to force majeure, the power outage may be a bit long, but please understand that the emergency repair work must also be carried out in accordance with the specified weather conditions. Once the weather conditions permit, the power supply personnel will rush to the scene as soon as possible to repair.

Restoring power supply is not a simple action. Power supply millet should go through a whole set of processes, such as draining water, removing foreign bodies, drying equipment with high-power thermal light source or blower, checking the situation of circuits and cables, testing equipment, grading trial power transmission, complete power transmission, etc., to ensure the safety of power supply recovery.
