| 摘 要： | 电力GIS设备在电力系统中有广泛的应用,GIS是运行可靠性高、维护工作量少、检修周期长的高压电气设备。但GIS也有其固有的缺点,由于SF6气体的泄漏、外部水分的渗入、导电杂质的存在、玻璃绝缘子老化及安装工艺等因素影响,都可能导致GIS内部故障。文章针对一起110k V GIS故障母差动作导致跳闸的事故,分析了事故处理过程和故障原因,并在此基础上提出了相应的防范措施,供设计、生产和运维人员参考。

| Abstract: | Electric power GIS equipment has been widely used in electric power system, GIS is the high voltage electrical equipment with high reliability, easy maintenance, less maintenance cycle. But GIS has its inherent shortcomings, as a result of SF6 gas leakage, external water infiltration, the existence of con-ductive impurity, glass insulator aging and installation technology, may result in the GIS internal fault. Aiming at the tripping accident caused by the bus protection action of 110kV GIS fault, the process and the cause of the accident are analyzed, and on this basis, the corresponding prevention measures are put forward, to provide the reference for the design, production and operation staff. |
