Sichuan Electric Power for 14 consecutive days, day and night, 500 kV as Yanmus transformation station

"The report scheduling, the 500 kV shoemon power station 5043 disconnecting the gate was successful." At 22:41 on September 20th, the duty member of the station reported to the State Grid Sichuan Electric Power Company Regulatory Center. It marks that more than 120 employees in Sichuan Electric Power fought after 14 consecutive days and nights, and the main change of 500 kV as Shimoto Power Station at the Luding earthquake resumed operation, which greatly alleviated the pressure of clean energy such as hydropower and other hydropower areas in the asbestos. Reconstruction of the earthquake -stricken area provides strong power protection.

The 500 kV as Shimota substation is located in Meiluo Township, Ya'an City. There are 500 kV of 7 times and 220 kV out 8 times. An important hub transformation station of the Sichuan -Tibet connected project. This earthquake caused a total of 9 high -voltage side tubes at the 500 kV of the station, and the main degree of oil leakage and the main change of the main change of the middle pressure side sleeve, which affected the dragon, Lizi Ping, Tianwan, Tianwan Hydropower and electricity stations such as river and other water and electricity stations access the Internet.

After the dangerous situation, relying on the advantages of the Group's group group of the State Grid Corporation, the State Grid Sichuan Electric Power News moved and responded quickly, and quickly approved the parameters of the damaged equipment of the asbestos station. Spare parts provide strong material guarantee for the station's repair work.

"In this repair work, every main change must go through more than a dozen procedures such as oil discharge, replacement of tube, vacuum, thermal oil circulation, pressure resistance, and bureau release tests. . The repair personnel need to discharge a main transformer for 180 tons of transformer oil like hemodialysis to the oil can for 48 hours, and then inject the thermal oil cycle of the body for 72 hours. 2.2 tons, 8.3 -meter -long sleeves should accurately insert transformers to increase seats according to the standard of 3 degrees ... "On September 19, according to the" 9.5 "earthquake repair deputy commander Wang Jin, the" 9.5 "earthquake in Sichuan Sichuan Introduction, "In order to accelerate the restoration of the station, Sichuan Sichuan Electric Power mobilizes 4 power supply companies in Leshan, Ya'an, Liangshan, and Mianyang to participate in the use of electricity protection. , Guide the optimization strategy. It provides a strong technical and reliable guarantee for the station's repair work. "

Faced with the large -scale operation site with 3 main changes and 10 sets of tubes hanging, State Grid Sichuan Electric Power held up the pressure, calmly faced the risks such as frequent excess and limited space operations, and coordinated on -site personnel arrangements, special vehicles and equipment scheduling Effectively control the safety risk of on -site operations.

In addition, the State Grid Sichuan Electric Power Arrangement on -site repair personnel were repaired for 24 hours, and the process and process of optimizing the process combined with weather changes at any time to ensure that the overall construction period was not affected. In the key procedures, the demolition and installation of 10 suite pipes are all implemented by employees of Sichuan ultra -high companies to ensure safety and quality. In just 14 days, the old sleeve removal, new sleeve installation, thermal oil circulation and post -repair test series were completed.

The Lord No. 3 of Ashami Station has become successful, restored the connection between 220 kV power grids and Sichuan main networks in the asparagal area, effectively alleviating the pressure of clean energy such as hydropower in the asbestos area, and providing a strong power guarantee for the rebuilding after the asbestos. And development motivation.

At present, the main change of the main part of the station 1 and 2 is undergoing tightness. It is expected to complete all the repair work in early October. (State Grid Sichuan ultra -high -pressure company Wang Zhiqi Chen Xingwang)
