摘　　要：新时代背景下,我国经济水平逐步提高,电力企业的发展得到了人们普遍的关注。对于我国农村,10kV配电线路是一类应用率最高的线路,但其经常会发生接地故障。一般最常见的因素是导线断线、绝缘子击穿以及导线和树木短接等。因此,相关工作人员必须做好研究工作,以提升线路运行的效率,并确保其安全性达到要求。主要描述了单相接地出现故障的具体原因,探讨了单相接地故障的危害,分析了接地故障的处理方式。Under the background of the new era,China's economic level has gradually improved,and the development of power enterprises has received widespread attention.For rural areas in China,10 kV distribution lines are the most widely used lines,but it should be noted that they often have grounding faults.Generally speaking,the most common factors are wire breakdown,insulator breakdown and short connection between wires and trees.To this end,the relevant staff must do a good job of research,in order to improve the efficiency of line operation and ensure its safety to meet the requirements. Mainly describes the specific causes of single-phase grounding fault,discusses the harm of single-phase grounding fault, analyses the treatment methods of grounding fault,and expresses some personal views and views on the application of new technology and equipment.
