　　Masking, stripping, crimping... Under the high temperature of 40 degrees Celsius, the "post-95" little girl Lu Tingyu stood "fully armed" on a 10-meter-high insulated bucket truck to carry out non-stop operations, and the sweat was dripping. Rolled down, soaked all over.

　　Lu Tingyu is an employee of Nanjing Yuanneng Electric Power Engineering Co., Ltd.'s R&D and Application Branch of Intelligent Uninterrupted Operation.

The company is responsible for the city's uninterrupted operations.

"Recently, Nanjing has continued to be hot, and some people joked that 'life depends on the air conditioner'. If we have a power outage, it will have a great impact on people's lives." said Chen Zhong, general manager of the branch.

　　The project of this operation is to connect power to the Changtangxu Pumping Station in Lukou Street, Jiangning District, Nanjing.

"If there is a power outage, nearly 1,000 households and business users in the surrounding Genfang Village and Changtang Village will need to be out of power for about 3 hours," said Xing Yibin, head of relevant business of the State Grid Jiangning District Power Supply Company in Nanjing.

　　Uninterrupted power operation is convenient for users, but it is a challenge for power workers.

"The main thing is to ensure safety, and live work means risks." Wang Xinyue, the person in charge of the project site, said that the staff must be well insulated throughout the process. "There are three layers of optical insulating gloves, the inner layer is cotton gauze gloves, and the middle layer is rubber. The outer layer is puncture-resistant sheepskin gloves, and an insulating helmet, heavy insulating clothing, and impermeable insulating shoes are required.”

　　The reporter weighed it, and the full set of equipment weighed six or seven pounds, and the electro-hydraulic pliers operated by the staff weighed more than 10 pounds.

"The temperature in the car body is almost 50 degrees Celsius. The working time is nearly one hour short and two or three hours long. After each operation, the clothes can be squeezed out of water." Lu Tingyu said.

　　Faced with a high-voltage current of 10 kV, the staff had to overcome their inner fears.

"When stripping and crimping, the current will discharge the metal and make a squeaking sound." Lu Tingyu said, "It took a while to get used to it."

　　"Summer is the peak period for electricity consumption, and the uninterrupted operation can make the surrounding residents and enterprises almost feel no impact." Chen Bingbing, director of the equipment department of the State Grid Nanjing Power Supply Company, said that from the elimination of distribution network line defects to the installation and operation of new equipment, From the replacement of old equipment and the emergency repair of faults, the scope of non-power-off operations is becoming more and more extensive.
