"Dancer" on the high-voltage line
Remember the live operation class of Xuanhua District Power Supply Center.
Zhangjiakou in winter, the cold wind is bleak. At 9 o'clock in the morning, when the reporter drove to the operation site of the Xuanhua District Power Supply Center, Yan Bin, the squad leader, had been working with his colleagues for more than an hour at a low temperature of more than ten degrees below zero.
When I first saw Yan Bin, he was in his early 40s, his complexion was dark, his square-framed glasses were a bit bookish, but his eyes behind the lenses were serious and firm.
Yan Bin carefully inspected the on-site safety precautions, emphasized the operation risk points and safety precautions, and then the live workers in the bucket wore insulated protective clothing and insulating gloves and boarded the insulated bucket arm car. The insulating protective clothing is yellow, made of special materials, airtight, nearly one centimeter thick, and weighs up to 4-5 kilograms, just like armor.
As the insulated bucket boom truck rises to the high altitude and enters the operation area, the high-altitude and ground personnel are highly coordinated and closely cooperated, and the work is carried out in strict accordance with the standardized operation requirements.
The cold wind in the field penetrated the thick coat like a knife, and the reporters on the ground shivered with cold, and couldn't help but hide in the direction of the shelter from the operation vehicle, while the staff in the bucket more than ten meters high could not avoid it.
We're used to it!Yan Bin said, "The weather is not bad, if it is summer, the temperature is scorching, after wearing live work clothes and insulating boots, it is airtight, and the whole person is like just 'fishing' out of the water after working in the bucket arm truck." ”
It is understood that Yan Bin and his colleagues are completing the regular inspection and maintenance of the 10,000-volt 537 Zhunong line, and the main operation is to carry out insulated packages.
Although it is a regular inspection and maintenance of the line, the significance is not trivial. As the temperature plummets and the peak period of electricity consumption ushers in, this inspection is particularly important to ensure the safe, reliable and stable operation of the local power grid during the peak winter.
The traditional practice is to operate after the power failure of the line, but the power outage will affect the normal electricity consumption of residents and surrounding enterprises, in order to achieve the user's 'zero perception', it is necessary to use professional technology to carry out low-voltage uninterrupted power operation. Yan Bin explained.
This would have been unthinkable 15 years ago. He said that at that time, there was no live operation in our city, and most people did not dare to imagine how to contact the live high-voltage line, and most of the electricians who often climbed up and down on the pole had seen the birds that were burned into charcoal on the high-voltage line, and the danger of live work can be seen.
In 2004, 23-year-old Yan Bin went to other places to learn professional knowledge of live work and obtained relevant certificates. In 2008, he and his colleagues set up the live operation class of the Xuanhua District Power Supply Center.
At first, Yan Bin was afraid that his family would be worried, so he didn't dare to tell his family that he was participating in live operations. When his mother asked, he pretended to be relaxed and said, "There is no danger at all if you tighten the screws and replace the parts." He has been working with live work for 15 years now, but one of the times he carried out live work is still fresh in his memory.
One afternoon in June 2014, next to a transformer near Mawangmiao in Xuanhua District, the live work team was making serious preparations.
At 14 o'clock, the operation officially began. "It was summer, it was very hot, and when the insulating bucket was raised, I counted one or two meters ...... in my heartThe moment the bucket stopped in the air, my mind went blank. Yan Bin recalled, "The insulating suit was very hot and not breathable, and the overalls inside were soaked all at once." I could only try to calm myself down and start doing it step by step. ”
10 minutes, 20 minutes, 30 minutes ......2 hours passed, and the live replacement of the transformer drop-out fuse was successful. At that time, in our city, there was no mature case to learn from the live operation technology of replacing transformer drop-out fuses, and there were no ready-made operating tools to use, and there was not even an industry standard for on-site operation. With experience and courage, Yan Bin completed this important task of special significance.
It has to be said that this is an unusual feat. The power people led by Yan Bin are a group of "dancers on the high-voltage line" who are highly skilled and dare to be the first. In the next 10 years, Yan Bin and his live operation class have created a number of good achievements in many fields of live operation in the city.
Since 2008, under the leadership of the General Party Branch of Xuanhua District Power Supply Center, as a demonstration post of Party members of Xuanhua District Power Supply Center, Yan Bin has led the live operation team to safely carry out more than 1,000 live operations and reduce the power outage time by more than 10,000 hours.
Labor is intense and dangerous, what makes you persevere?Someone asked Yan Bin. He said: "Someone must do the work, we are learning electricity, who will do it if we don't do it?"(Heshan News reporter Ma Mingming, Liu Fang, correspondent Jia Shuwen).
