一起10kV配电线路单相接地故障分析与思考

One analysis and consideration of single-phase grounding fault on distribution line

配电网单相接地故障是长期困扰配网运维人员的一个难题。本文针对一起具体的10kV配电线路单相接地故障,指出目前运维人员处理配网接地故障具体流程,分析停电时户数和计算方法,从配电网单相接地的预防和发生单相接地后如何更快查找故障点两方面提出几点具体思考。

Single-phase grounding fault on distribution network is a difficult problem to electricity workers.In view of a specific 10kV distribution network single-phase grounding fault,this paper points out the specific process of single-phase grounding fault at present,analyzes the number of households and calculation methods during power outage,and puts forward several specific thoughts on how to prevent single-phase grounding faults and how to find fault points faster when single-phase grounding.
