农村配电网 10 kV 线路重合闸成功率的影响因素研究

Ｒesearch on Factors Influencing Ｒeclosing Success Ｒate of 10 kV Lines in Ｒural Distribution Network

摘要:

重合闸是电力系统中提高供电可靠性的一种有效手段。目前，大部分的农村配电网 10 kV 线路都装设有重合 闸装置，然而实际运行时重合闸成功率普遍不高。针对此问题，首先总结了重合闸时间整定原则，然后对影响农村配 电网 10 kV 线路重合闸成功率的相关因素进行了详细的分析，最后依据短时停电的定义和要求，梳理了几点建议，为 电力企业在提高农村配电网 10 kV 线路重合闸成功率方面提供参考。

Abstract:

Ｒeclosing is the effective way to improve the reliability of power supply in power system． At present，most of 10 kV lines in rural distribution network are equipped with reclosing devices，but the success rate of reclosing is generally not high in actual operation． Aiming at this problem，firstly the reclosing time setting principle is summarized，and then the related factors influencing the success rate of 10 kV line reclosing in rural distribution network are analyzed in detail． Finally based on the definition and requirements of short － time power outages，some suggestions are put forward，which provides a reference for improving the success rate of 10 kV line reclosing in rural distribution network．
