Chongqing: A variety of means to strengthen important line equipment inspections

Early in the morning on August 18th, under the No. 3 Tower 3 Tower of Mushan 220 Kicheshan Caojiang West Line at the Grasshill Street Office of Hechuan District, Chongqing, Zhang Zhengping, an employee of Hechuan Power Supply Company's transmission and maintenance class, and colleagues operated a white drone to quickly quickly quickly Lift off, prepare for the comprehensive "consultation pulse" of gold gear, insulation, wires, etc., and timely discover and eliminate hidden dangers affecting the safe operation of the line.

"This line connects two 220 kV substation and a 110 kV substation, which is very important to ensure power supply in the area." Zhang Zhengping said that the West West Line of Caojiang is located between the mountains and hills. After turning over the mountains, it took more than half an hour to inspect a base tower. In the hot summer, this inspector is a great physical and mental test. After the application of drone inspection, it only takes about 10 minutes to pass the inspection of the tower and line, and the inspection efficiency and quality are greatly improved.

Dangerous situations such as mountain fire.

Since the summer, Chongqing has released eight high -temperature red warnings. On August 18, the temperature of the national station in Beixi District reached 45 degrees Celsius, which once again broke the highest temperature since Chongqing's weather record. Continuous high temperature and drought weather brings great tests to the safe operation of the power grid. While the State Grid Chongqing Electric Power Company, while carefully doing foreign purchases, power grid operations, etc., use intelligent inspection equipment such as drones, transmission panoramic monitoring platforms, inspection robots, etc., and strengthen dense channels, important lines, and important substations Inspection and maintenance, make every effort to prevent mountain fires and ensure the safe operation of line equipment.

From June 15th to August 18th, more than 6,000 front -line operation and maintenance personnel and more than 2,000 vehicles were dispatched to the State Grid Chongqing Electric Power. At the same time, the 77 -seater substation was resumed. Someone was on duty. It took auxiliary cooling measures for 255 main transformers to eliminate 868 main network defects, and implemented 145 distribution network reinforcement projects; set up 56 fire -fire squatting points, successfully dealt with 36 mountain fire incidents incidents It has effectively guaranteed the safe operation of Chongqing Power Grid. Anhui: Scientific scheduling to ensure that the power supply is smooth and orderly
