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110 kV 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。
전력GIS설비재전력계통중유엄범적응용,GIS시운행가고성고、유호공작량소、검수주기장적고압전기설비。단GIS야유기고유적결점,유우SF6기체적설루、외부수분적삼입、도전잡질적존재、파리절연자노화급안장공예등인소영향,도가능도치GIS내부고장。문장침대일기110 kV GIS고장모차동작도치도갑적사고,분석료사고처리과정화고장원인,병재차기출상제출료상응적방범조시,공설계、생산화운유인원삼고。
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.
