摘要
为了解决1 000kW轨道车接地故障问题,提出一种接地保护电路,可以根据接地电压判定接地故障。通过仿真建模的方式进一步验证了诊断分析的正确性,为轨道车接地故障诊断提供了技术支持和经验积累。
In order to solve the problem of grounding fault of 1 000 kW railcar, a grounding protection circuit is proposed, which can determine grounding fault according to the grounding voltage. The correctness of the diagnosis analysis is verified by simulation modeling, which provides technical support and experience accumulation for track vehicle grounding fault diagnosis.
