摘要
针对VD4断路器传动机构闭锁导致断路器无法合闸,从而使合闸线圈烧毁的事件,通过分析断路器拒动及合闸线圈烧毁的原因,提出了完善断路器控制回路的方案,提高了设备的可靠性。
An event in which the circuit breaker cannot be closed due to the blocking of the VD4 circuit breaker transmission mechanism,so that the closing coil burns out.By analyzing the reasons for circuit breaker rejection and closing coil burnout,a scheme to improve the circuit breaker control loop is proposed,which improves the reliability of the equipment.
