500 kV GIS及罐式断路器分合闸时间测试结果探讨

Discussion of Mechanical Characteristic Test of the Breaker of GIS and T-GCB of 500 Kilo-voltage

对于目前500 kV GIS及罐式双断口断路器分合闸时间测试方法只能得出一个断口时间结果的实际情况,指出并不能完全反映断路器整个机构的工作状态,并提出比较多次断路器分合闸时间的方法,通过历史数据的变化来考察断路器两个断口的实际工作状态。

There is a situation that the close and open time test of the breaker of GIS and T-GCB of 500 kV that only one test result can be seen from double breaks.This article points that it can not reflect the whole working state of the,and gives a solution from comparison of many test results,which reviews the real operation of the two parts through the change of history data.
