摘要
介绍了一起核电站备用电源220kVGIS故障查找及处理过程,通过历史试验、维护记录、故障元件检测等方面综合分析,查到故障是由微小颗粒在高电场强区域导致气体绝缘失效引起。最后对GIS设备施工过程中的清洁度控制提出建议。
A 220 kV GIS fault finding and handling process of nuclear power station standby power supply was introduced,Through comprehensive analysis of historical test, maintenance record, failure component detection, etc., The fault reason was caused by tiny particles in the high intensity electric field which caused the gas insulation to fail, and this was relatively rare. Some suggestions of the cleanliness control of GIS overhaul work was proposed.
