摘要
本文介绍了一起GIS设备支撑绝缘子故障的案例,内容包括现场试验分析过程、解体检查、事故原因分析。此次故障的原因是由于支撑绝缘子沿面放电导致的开关跳闸,文中也给出了下一步工作建议,供同类电厂借鉴。
This paper makes an introduction to a fault caused by GIS supporting insulators,including on-site experiment analysis,dismantling inspection and cause analysis.Having made clear the fault was caused by the switch tripping due to the surface discharge of supporting insulators,this paper puts forward suggestions for power plants of the same type.
