| 摘 要： | 本文主要对某500kV变电站在进行500kV线路停电倒闸操作中,500kV母线侧刀闸多次出现分闸异常事件进行分析,得出主要原因以及提出发生类似事件应该如何正确处置.该事件主要是因为500kV母线侧垂直伸缩式刀闸因动静触头无法正常分开而导致分闸异常,进一步可能发生母线扯落事故.总结经验,提出正确的应急处置方法,减少刀闸操作异常时间,对保证电网稳定安全运行有重大意义.

| Abstract: | This paper mainly in a 500kV substation were 500kV power switching operation,500kV busbar side switches appeared several times tripping incident analysis, it is concluded that the main reason and put forward the occurrence of similar incidents should how to correct disposal. The event is mainly because the 500kV bus side vertical telescopic knife for contact to separate normal tripping caused abnormal,further possible off bus accident.Sum up the experience, put forward the correct emergency handling method, reduce the abnormal operation time,to ensure the safe operation of the power grid is of great significance. |
