摘    要:本文在介绍直流接地产生的原因及危害基础上,利用直流接地检测仪与万用表分段电压测量法,结合某变电站一起直流接地典型缺陷的处理案例,重点分析变电站直流接地故障的查找步骤和处理方法.实践表明,该方法能够有效解决站内直流系统间歇性出现的直流接地现象,提高系统运行的可靠性.

关 键 词:变电站  直流接地  缺陷处理

Finding and treating method of DC grounding fault in Substation
Abstract:This paper introduces the reasons and harms of DC grounding generated on the grounding detector and the multimeter block by DC voltage measurement method,combined with a substation DC grounding of typical defect cases,focuses on the analysis of search steps and processing method of substation DC grounding fault.The practice shows that this method can effectively solve the DC grounding phenomenon in the station DC system,and improve the reliability of the system.
Keywords:substation  grounding  defect treatment
