牵引变电所直流系统接地危害分析及应对措施探究

摘要

The railway has brought great convenience to many travelers and the safety of railway is related to the safety of thousands of passengers.In order to ensure the safety of the railway, the power supply system support is needed.This article studied the associated ground hazards which appeared in traction substation DC system as the core of study.It also analyzed the DC grounding connotation and the type and the corresponding causes.The harm caused by DC grounding was studied and the DC ground faults were found and excluded.Some preventive measures were put forward.This provided a reference for the follow-up of the railway DC system and the research of variable electric traction.%铁路为众多旅客出行带来较大便利,可以说铁路的安全关系到万千旅客的出行安全.而要想确保铁路实现良好安全运行就需要牵引供电方面系统的支持.文章以牵引变电中直流系统出现的相应接地危害作为研究核心,分析直流接地内涵以及类型和相应的产生原因,对直流接地引发危害进行研究,查找排除直流接地故障,并且提出防范措施,为后续铁路直流系统以及变电牵引方面的研究提供参考依据.
