摘要
通过一起220 kV断路器分闸后发生分闸线圈烧毁的故障案例,对断路器本体三相不一致保护回路、分合闸控制回路以及分合闸线圈烧毁故障原因进行了分析和讨论,并提出了相应的防范措施与改进方案,进一步保障设备安全可靠运行。
Based on a fault case that the opening coil burned out after a 220 kV circuit breaker was opened,the causes of the three-phase inconsistent protection circuit,the opening and closing control circuit and the burning out of the opening and closing coil of the circuit breaker are analyzed and studied,and the corresponding preventive measures and improvement schemes are proposed to further ensure the safe and reliable operation of the equipment.
