摘要
为保证直流系统的正常运行,查找直流接地故障的时间应尽可能缩短。分析了查找直流接地的方法并形成流程图,从而使查找过程规范化、合理化;并提出直流系统应尽量按分段直流母线进行配置,从而使查找环境得到优化。这两方面都对缩短查找直流接地故障的时间有很大帮助而且具有较强的可行性。
To ensure normal operation of the substation, the DC system grounding fault should be detected as quickly as possible. Fault detect methods are analyzed. And the flow chart is drawn out, which makes the detection procedure orderly and rational. It also suggests that the DC feeders apart connecting to detached bus should better for detection condition. Both of those are practical and helpful to shorten the detection time.
