摘要
华东瓶窑变电站为适应500 kV电网短路电流的增长,对500 kV母线作分段运行改造。介绍了改造中选择应用气体绝缘金属封闭输电线路装置(G IL)的考虑,详细论述了对G IL的技术要求,总结了设备制造、施工和运行相关问题的处理经验,还对其应用前景作了探讨。
To deal with the increased short-circuit current in the 500 kV power grid, the Pingyao Substation was retrofitted, with its 500 kV busbar sectionalized. After careful consideration, the gas-insulated transmission lines (GIL) was used in the retrofit. The technical requirements for the GIL are analyzed, and problems occurred in equipment manufacture, construction, and operation as well as the solutions are summarized, and the application prospects of GIL is also discussed.
