摘　　要：通过分析HX_D1C型电力机车辅助变流器接地检测原理,说明了辅助变流器接地保护产生的机理和原因,对辅助变流器接地产生的因素进行了分类。通过辅助变流器接地故障因素分类,理清了产生辅助变流器接地涉及到的部件,理顺了接地故障排查的步骤和顺序。通过下载机车严重故障数据和机车事件记录数据,结合经验判断和故障现场实际,阐明了从经验分析、初步检查、三相负载、辅助绕组次边等7个步骤对辅助变流器接地故障检查,逐一排查,形成了辅助变流器接地故障处理思路。According to analysis the principle of auxiliary converter grounding detection HXD1C electric locomotive, it was explained that the auxiliary converter grounding protection of the principle and cause, and the factors of auxiliary converter grounding are also classified here in this article. By the classification of auxiliary converter grounding fault factors, it was sorted out the components in volved in generating auxiliary converter grounding and the steps and sequence of grounding fault rectification are straightened out. Ac cording to download data and analysis the fault data of locomotives and locomotive incident records, in combined with the experience and the actual situation of the fault, expatiated the seven steps from the experience analysis, preliminary review, three--phase load, auxil iary current transformer winding side to auxiliary converter grounding fault inspection in details, every piece of investigation and formed a more detailed and complete auxiliary converter grounding fault processing ideas.
