That is, when the line failure, the relay circuit breaker tripping, the device auto-reclosing after a short time interval, so that a re-breaker.
即当线路出现故障，继电保护使断路器跳闸后，自动重合闸装置经短时间间隔后使断路器重新合上。
Through analyzing the reclosing of circuit breaker in middle of line-transformer strings, the existing problems were figured out and the modification measures were put forward.
通过对线-变串中开关重合闸问题的分析，找出了存在的问题，提出了改进意见。
This requirement has brought about the development of breaker operating mechanisms that are not only high-speed opening, but are also high-speed reclosing.
这种要求已促使研制出具有不仅能快速分闸而且也能快速重合闸的断路器操动机构。
For LW14 and LW15 SF6 circuit breaker, the reason of reclosing block after opening operation has been analyzed in the paper.
对部分LW14,LW15型SF 6断路器分闸操作后重合闸闭锁的原因进行了分析，提出了改造方案，并在实践中取得了良好效果。
HV and EHV transmission lines are equipped with split-phase breaker. If a longer reclosing time is setting in a heavy load line, the system may swing after the trip without fault of remote breaker.
高压、超高压输电线路的开关为分相开关，当对侧开关单相偷跳后，在线路负荷比较重、同时重合闸动作时间比较长的情况下可能引发系统振荡。
