摘要
1000kV特高压长治站是我国首个特高压工程的起点站,连接华北与华中两大电网,特高压长治站500kV侧HGIS设备漏气较为频繁,给系统安全运行造成不小压力。主要介绍一起典型的500kV新型高压开关设备HGIS(Hybird Gas Insulated Switchgear)漏气缺陷的分析与处理,通过对漏气原因的分析,根据现场实践经验,制定了相应的预防、解决措施,具有较强的应用价值。
1000 kV UHV Changzhi substation is the initial station of the first UHV transmission project in China. The UHV transmission line links North China Power Grid and Central China Power Grid. However, gas leakage occurs frequently at 500 kV side of Changzhi substation, which poses a big threat to the safe operation of the system. This article is focused on the analysis and treatment of a typical gas leakage accident of a 500 kV HGIS. According to the analysis on the causes of leakage, corresponding measures are put forward for prevention and solution, which has great value in application.
