Recently

Many parts of the country have experienced continuous heavy rainfall

The flood prevention situation is severe

Whenever there is a rainstorm

When power failures occur

You can see

A group of people wearing work clothes and insulated boots

Going against the flow in the rain

They are the power repair workers

They race against time to repair damaged lines

Ensuring the power safety of thousands of households

Behind this repair

Is a scientific and efficient “Repair strategy”

Today

Let's reveal

The power repair workers' “Repair secrets”

 

First, we need to clarify

The rainstorm warning signals are based on

The amount of rain, the level of danger, and the development trend are divided into

Blue, yellow, orange, and red

The response measures of the power industry are also different for different warning signals

The response measures of the power industry are also different

In the "Management Measures for Emergency Plans of Power Enterprises"

Specifically, the warnings are divided into four levels

Level Ⅳ/Blue, Level Ⅲ/Yellow, Level Ⅱ/Orange, Level Ⅰ/Red

And linked to the government's warning levels

After receiving the warning information

Immediately initiate the corresponding level of emergency response

Blue warning (Level Ⅳ):

Strengthen monitoring

Check emergency supplies

Notify relevant personnel to stand by

Yellow warning (Level Ⅲ):

Install waterproof facilities and drain water in advance

Organize repair teams to stand by

Orange warning (Level Ⅱ):

Establish a front-line command center

Proactively shut down equipment that may be flooded

Red warning (Level Ⅰ):

All personnel enter emergency status

Coordinate external rescue forces

Implement the highest level of control

Each level of response is progressive

Ensuring timely handling

And maximizing the safety of the power grid operation

 

When a rainstorm comes

Power workers often take the initiative to cut off the power

This is not a "power outage"

But "life saving"!

In the "Regulations on Power Safety Guarantee Work" and "Regulations on Emergency Management of Power Safety Production"

It is mentioned

"Proactive power outage for risk avoidance"

Because this can

Prevent electric shock accidents caused by energized equipment or lines leaking electricity when encountering water

Avoid damage to power equipment due to prolonged immersion in water

Shorten the power restoration time after the water recedes

Power repair is not brute force

But a scientific process

Scientific repair trilogy: "Water recedes, people enter, electricity is on"

It's not necessarily to wait until the water completely recedes before entering the field

When the water recedes to a safe height

Repair workers immediately use professional equipment to detect the "health status" of the lines

Then

The repair team transforms into a "power special team"

Advance team diagnosis → Equipment team spare parts → Operation team repair → Logistics team support

Main lines first, then branches

Careful friends will find

Sometimes the repair is not finished yet

The lights at home are on

Why is that?

This is because the power company has used "all kinds of skills"

✓   Load transfer technique : Connect the power of the power outage area to the good lines

✓   Mobile emergency power supply : Generator cars are driven to the entrance of the community, and helicopters transport power equipment into the disaster area

Why "Restore power first, then repair" ？

It's like a burst water pipe at home:

Turn off the main valve to stop the water (temporary power restoration)

Then slowly repair the pipe (permanent repair)

These policies and principles

Are actually for

Minimize the impact of disasters on power supply

All for the purpose of getting electricity to everyone as soon as possible

Finally

Xiaoye reminds everyone:

Stay away from power poles and transformers on rainy days

Be careful to avoid puddles on the road

Safety first!
