On May 19th, before the start of electrified work at the UHV test site of the Chinese Academy of Electric Power, the staff under the tower were nervously preparing. The images in this article are from Xinhua.com.
The reporter learned from Anhui Transmission and Distribution Engineering Co., Ltd. that on May 19th, the company’s personnel in the live-in class successfully completed the ±1100 kV high-voltage line on the 88-meter analog line tower of the UHV Experimental Base of the China Electric Power Research Institute. Job simulation test.
On May 19, on the UHV test site of the Chinese Academy of Electric Power, live workers used the 'horizontal swing from the bottom to the top of the tower' to enter power.
'This is the first time that the live work enters the ±1100 kV UHV field. 'According to the person in charge of Anhui Transmission and Distribution Engineering Co., Ltd., this simulation test is to guarantee that the transmission of ±1100 kV from the West Power Station will be 'Xinjiang Changji-Anhui Ancient Spring' Research projects for the operation and maintenance of UHV DC projects. The project runs through Xinjiang, Gansu, Ningxia, Shaanxi, Henan and Anhui provinces (districts). It is the highest voltage level in the world, with the largest transmission capacity and the longest transmission distance. High-voltage transmission project, there is no operation and maintenance experience at home and abroad for reference.
According to reports, the line has high voltage levels, high parameters, long distances, large cross-sections of wires, and complicated geo-environmental environments along the line. The reliability of the safe operation is demanding. When encountering unexpected situations such as external breaks, lightning strikes, and pollution flashes, , Can not be on-site power failure at any time on-site processing. Live working in the high-voltage electrical equipment without power failure for maintenance, testing, to avoid maintenance blackouts, ensure reliable power supply. The success of this simulation will effectively enhance the ability of O&M units to ensure the safe operation of UHV power grids. , To reduce the economic loss caused by the blackout of the line.
