摘　　要：神华广东国华粤电台山发电有限公司(以下简称:国华台电)自2002年投产以来,输煤电气设备运行稳定,从未发生过整段母线失电故障。但2013年7月开始,输煤6k V开关柜2BCB段码头电源开关2BCB10连续多次报‘接地’故障跳闸,导致码头6k V二段母线失电。文章主要对故障处理过程、故障分析方法进行总结,找出导致故障发生的根本原因,为后续故障快速处理提供良好的参与依据。Shenhua Guangdong Guohua Yuedian Taishan Power Generation Co., Ltd.（Guohua Taidian for short） produced eleetrieity since 2002. The electric equipments for coal transportation ran stably, and there was no power failure in the whole bus before July 2013. After that time, 2BCBIO power switch had some grounding failures in 2BCB stage in 6kV switch cabinet, that caused 6kV two-stage bus lost power al the wharf. The paper summarized the failure working process and the failure analyse methods, and found the ultinmte reason caused the failings, that provided the good reference for the failures processing for the future.
