Analysis and Treatment Measures for Accident Caused by Internal Discharge of 220kV GIS CHEN Yi,WANG Lin,RAN Yue

针对一起220 kV GIS内部放电故障进行分析,从事故前运行方式、一次设备、保护配置等基本情况入手,按二次设备检查、一次设备检查、气体分析的流程展开最终故障定位,然而通过解体检查找到具体故障原因,并对此类放电故障提出了反事故措施建议。最后从运行操作和检修工作两个方面进行事故处理,使设备恢复正常运行。

An internal discharge fault of 220 kV GIS equipment is analyzed in this paper.First,the operation mode before the accident,the primary equipment and protection configuration are introduced.The final fault location is carried out,according to the process of secondary equipment inspection,primary equipment inspection and gas analysis.Then,the specific cause of the failure was found through the disassembly inspection.The anti-accident measures and suggestions are put forward for this kind of discharge fault.Finally,the accident treatment is carried out from two aspects of operation and maintenance to make the equipment return to normal operation.
