摘要
对一起因220kV一次设备在倒闸操作过程中,电动机电源开关突然跳闸,致使隔离开关动、静触头之间产生电弧,危及电网和设备安全的这一危险情况进行了分析,找出危险根源,强调执行反事故措施的重要性。
In the process of switching operation of 220kV primary equipment, the switch of motor power source tripped suddenly, and then electric are occurred between the moving contact and stationary contact of disconnecting switch. Therefore, the safety of power grid and equipment were threatened. After analyzing the situation, the cause is found out that is electromagnetic interference, and the importance of carrying out the anti- accident measures is emphasized.
