拉西瓦水电站地处黄河上游龙-青河段,具有装机容量大、电压等级高、地形复杂、海拔高等特点。电站800kV GIL的设备安装海拔为2460米,超高电压的GIL在国内暂无可靠的运行和设计经验,而800kV GIL在高寒、高海拔地区的安装方法及工艺也尚属空白。介绍了800kV GIL的特点,基本结构,安装方法和工艺,对于GIL在国内的安装和广范推广提供相关的参考。
Laxiwa Hydropower Station is located in the upper reaches of the Yellow River Dragon - Green River, with installed capacity, high voltage levels, complex terrain, high altitude and so on. Installation of 800kV GIL at power plant is 2460m above sea level. Ultra-high voltage GIL has no reliable operation and design experience in China. However, the installation method and technology of 800kV GIL at high altitude and high altitude are still blank. The characteristics, basic structure, installation method and process of 800kV GIL are introduced. It provides relevant references for the installation and promotion of GIL in China.
