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。

The operating logics and processes of the automatic transfer of the incoming linebreaker and the bus-tie switch are presented.
给出了进线断路器备自投和母联开关备自投的工作逻辑和投切过程。

With an example of two lines short and grounding fault, and one side of breaker of grounding fault line being cut off, the paper illustrates the principle of this calculation method.
