一起GIS隔刀传动失效导致的绝缘故障及分析
|
摘要
GIS隔离开关分合闸操作一般是通过安装在边相或者中间相上的操作机构带动相间连杆运动来实现的,相间传动机构一旦发生异常,会影响到其它相隔离开关本体的分合闸操作,甚至引起GIS的绝缘故障。笔者结合一起GIS隔离开关因传动机构失效引起GIS绝缘故障的案例,分析故障的根本原因,并提出了解决措施,提高了该GIS及电网的安全运行水平,具有良好的应用价值。
GIS disconnector closing operation is generally achieved through the installation in the side or middlephase of the operation mechanism driven inter phase connecting rod movement,alternating transmission mechanismonce an exception occurs,affect other apart from the switch body switching operations,and even cause GIS insula-tion fault. According to together GIS disconnector cause of insulation defects in GIS case because of the failure of thetransmission mechanism,root cause failure analysis,and puts forward the solving measures,and improve the levelof safe operation of the GIS and grid,and has good application value.
