摘要
直流系统是变电站的保障性系统,发生故障时会影响变电站的安全可靠运行,其中直流系统接地占直流系统故障的比例最高.针对直流系统接地故障实例进行分析研究,并结合工作实践经验,探讨了查找和排除直流接地故障的技术方法.
Abstract
The DC system serves as the guarantee system for substations,and any faults within it can signifi-cantly impact the safe and reliable operation of the substation.Among all potential issues,grounding faults in the DC system account for the highest proportion.This paper aims to discuss technical methods for detecting and eliminating such grounding faults based on case analysis,research,and practical experience.
