摘要
文章对500kV线路单相接地故障重合闸不成功的原因进行分析,并提出调整两侧重合闸的定值时限的方法,使两侧的断路器保护能在故障的情况下进行有序配合,提高了断路器重合闸的正确动作率。
This paper analyzes the reasons for the single-phase grounding reclosing fault of 500 kV line,and proposes a method to adjust the setting time of the reclosing on both sides of the line to ensure that the circuit breaker protections on both sides can coordinate orderly under the fault condition,which improves the correct action rate of circuit breaker reclosing.
