摘　　要：我国大部分的配电线路都是在户外,容易受到雷电等恶劣天气的影响,增加线路出现故障的概率。配电网出现故障将会出现停电的情况,会对人们的日常生活带来影响,并且也会对部分企业的生产产生干扰。为了降低配电网的故障概率,实现配电自动化势在必行。应用故障指示器能够准确地对故障进行判断与定位,为日常维修与保养提供参考。基于此,阐述以故障指示器为基础对配电网接地故障进行定位的原理与方法。Most of the distribution lines in China are outdoors,which is easy to be affected by lightning and other bad weather,increasing the probability of line failure.Power failure will occur in the distribution network,which will not only affect people’s daily life,but also interfere with the production of some enterprises.In order to reduce the fault probability of distribution network and realize distribution automation,the application of fault indicator can accurately judge and locate the fault,and provide reference for daily maintenance and repair.Based on this,this paper will describe the principle and method of grounding fault location in distribution network based on fault indicator.
