影响10kV配电线路故障的几个关键问题探讨

10kV线路故障以中压线路故障率为衡量标准,中压线路故障率=中压线路开关跳闸次数/统计的中压线路百公里年数。本文从分析影响10kV配网线路故障的几个关键因素入手,以佛山市高明区10kV配网线路运行维护实际经验为例,从分析传统降低10kV线路故障率的手段,导出利弊,提出有效措施,进而降低10kV线路故障率。

Discussion on Key Factors of Affecting 10KV Distribution Line Fault

The standard of measurement in 10kV line fault is based on medium pressure line failure rate.The medium pressure line failure rate is specific value between numbers of switch trips of medium voltage line and number of years of one hundred kilometers of statistical medium-voltage line.From the analysis of key factors affecting 10kV distribution network line fault,based on the case of practical experience of operation and maintenance of 10kV distribution network lines in Gaoming district of Foshan,this paper analyzed the traditional means to reduce the failure rate of 10kV line,so as to derive advantages and disadvantages,come up with effective measures and then reduce the failure rate of 10kV line.
