摘　　要：结合线路重合闸方式和不同类型断路器机构闭锁条件,讨论分析断路器机构闭锁后发生线路故障时保护装置可能出现的各种动作情况,提出了保护中"低气压闭锁重合闸"接取外部闭锁信号的问题,并给出各电压等级线路断路器机构闭锁的实现方式。By line reclosing mode and different blocking conditions of circuit breaker,the paper expounds various actions of the protection device that may occur when the circuit breaker is locked and presents a problem that"low-pressure block reclosing"receives external blocking signal in the protection;besides,it suggests the implementation of the circuit breaker mechanism block at each voltage level.

关 键 词：断路器 线路保护 低气压 重合闸
