| 摘 要： | 当电力线路或运行设备出现故障时,开关的正确开断是保护电网能够正常运行的重要手段。然而在开关可靠性已经颇高的今天,开关拒动的情况依然频繁出现。电网中运行设备的开关拒动以及保护的多重拒动或误动,都可能引起电网事故,甚至可能迫使电网瓦解并造成大面积的停电事故。就引起变电站开关拒动的几点因素进行探讨,并针对这几点因素提出防范措施。

| Abstract: | When the faults happened in the power circuits or the electrical power units,the correct operation of switchgears is quite important so that it can protect the normal operation of power grid.But sometimes a few of the switchgears don't operate regularly even nowadays.The misoperation of switchgears could cause the accident which would break down the grid.The factors which cause the malfunction of switchgears are analyzed and some countermeasures to improve the existing problems are put forward. |

| Keywords: | switchgear malfunction extra-high current saturation of current transformer |
