| 摘要: |
| 电网中运行的线路保护装置的重合闸误动作,将会引起人身以及电网事故。结合整组试验,WXH-800系列线路保护装置的重合闸原理和电气设计图进行综合分析,发现WXH-800系列线路保护装置存在重合闸误动作的原因,提出了3种解决问题的方法,即控制回路断线时使重合闸放电、SPT把手就地时使重合闸放电、给KTP正名,并对每种方法的利弊进行了比较。 |

| Abstract: |
| The incorrect reclose of line protective devices in electric power system will result in personal injuries and system accidents. The principle and electrical design of WXH - 800 series line protective device are analyzed combined with tests . Causes of incorrect reclose are concluded. Three countermeasures are brought forward:discharge the recloser when the control loop appears broken line or the handle SPT is set local,make KTP reflect the actual state of circuit breaker. The advantages and disadvantages are compared . |
