摘要
介绍了深溪沟水电站500 kV GIS隔离开关分合闸故障的状况,分析了故障产生的原因,提出了故障处理及预防措施,并指出,在设备检修维护时,应特别注意检查能量输出及传递的关键连接部位;应建立合理有效的检测手段,以避免设备发生非正常分合故障。
A switching fault of the isolation switch is observed in the 500 kV gas insulated switchgear（ GIS） in Shenxigou Hydropower Station. Possible reasons of this fault are analyzed. Corresponding treatment and prevention measures are proposed. It is demonstrated that the critical connecting positions for the energy output and transmission should be carefully inspected during the device overhaul and maintenance. Effective fault inspection procedures should also be adopted to avoid such switching fault.
