摘要
瞬时性故障重合闸不正确动作将降低供电可靠性,增加线路停电时间,给客户和供电公司带来不必要的损失。对某35 k V变电站内一起电磁式断路器重合闸失败的原因进行分析,发现蓄电池老化引起合闸电流不足是导致事故发生的根本原因,并就该情况对相关变电站提出了相应的处理措施和注意事项,以杜绝类似故障的再次发生。
Reclosing failure on transient fault could reduce the reliability of power supply, prolong outage time ,and bring about unnecessary losses to customers and supply company.Battery deterioration is found to be the cause of an electromagnetic breaker reelosing failure occurred in a 35 kV transformer substation.In order to prevent the similar failure,anti-accident measures and precautions are proposed.
