At night, the State Grid State Grid Huzhou Power Supply Company carried out the "zero repair" to protect the high -voltage "great arteries"

"Now I will explain today's work tasks, 1,000 kV Antang Ⅰ line 18#Tower right line blue ground line hanging work ... I hope everyone will perform their duties and pay attention to their personal safety when working on the tower. Starting now. "At 1 am on July 14th, near Fangjiazhuang Village, Heping Town, Changxing County, Huzhou, Liu Pingping, deputy squad leader of the transmission inspection and maintenance of the power supply and transportation inspection center of State Grid, is arranging the task of" zero -point repair ".

At the work site, the operators on the nine towers boarded a 50 -meter -high work site, and they were with 1 on -site person in charge, 2 safety guardians, 1 technical part -time inspection, and 16 ground cooperative personnel with high temperature and mosquito bites. Complete the replacement of the jump compound insulator, and from the tower to the tower to return to the ground. At 3 o'clock in the morning, after two hours of continuous fighting, State Grid Huzhou Power Supply Company, Provincial Ultra -high -voltage Company, and Provincial Provincial Transfer Company made full cooperation and closely completed at 50 meters of high -voltage 1,000 kV Antang I. 17 Tower jumping line composite insulators break the emergency repair task, and the clothes and pants of the repair personnel have long been soaked by sweat.

It is understood that on the morning of July 13th, Huang Songlin, Miao Zheng, and Xu Guohua, the operation and maintenance center of the State Grid Huzhou Power Supply Company, discovered 1,000 kV Antang Ⅰ#17 towers in the daily inspection of the transmission line. Small -side composite insulators are broken. If the hidden dangers are not eliminated in time, a wire drop may occur at any time, resulting in the lines of the line, which will affect the safe and stable line of the line, leading to the interruption of the power supply of UHV lines.

1,000 kV Ansang I starts at Anji Station in Zhejiang Province, ends at Liantang Station in Shanghai, with a total length of 162.9 kilometers and a rated transport capacity of 6 million kilowatt hours. The channel is of great practical significance to alleviate the tension of Shanghai's electricity consumption, promote economic and social development, and ensure safe electricity.

"At present, the hottest time in the summer, the electric load is heavier during the day, so we chose the time of the night's electricity trough to carry out maintenance to reduce the impact of power outages on residents." Liu Pingping said. At the current high temperature and heat, the load of electricity in the summer is continuously rising. In order to minimize the risk of the power grid operation, to ensure the smooth development of this night repair, the company strengthens the communication and connection with the provincial ultra -high -voltage company and the provincial -provincial transformation company. Carry out on -site surveys, carefully compile the "1000KV Ansang Ⅰ line 17#tower, jump string of broken emergency and emergency and coolery operation guidance", secretly deploy on -site repair safety, technical and organizational measures, strictly implement on -site operational risk control and on -the -job place to place in place Make sure that the process is foolproof. This time it eliminated the critical defects of UHV lines, effectively guaranteed the safe and stable operation of 1,000 kV Antang Ⅰ line large grids, ensured the continuous transportation of large power artery power, and provided strong and reliable power protection for the peak summer.
