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。
2
Therefore the research on new principle of protection and adaptive auto-reclosing technique for UHV transmission line is of great practical significance.
因此研究特高压输电线路的继电保护新原理及自适应重合闸技术具有重要的现实意义。
3
The protective speedy act is combined with auto-reclosing mode to greatly enhance the reliability of power supply.
