摘　　要：阐述发电机变压器组单元接线方式的案例分析,当主变低压侧出现永久故障,而主变低压侧接地保护未配置跳闸功能,无法快速切除主变低压侧接地故障时的问题与影响、应对措施。This paper describes the case analysis of unit wiring mode of generator transformer unit. When permanent fault occurs on the low voltage side of the main transformer, and the grounding protection on the low voltage side of the main transformer is not configured with tripping function, the problem, impact and countermeasures cannot be taken to quickly remove the grounding fault on the low voltage side of the main transformer.

关 键 词：单元接线 接地保护 案例分析
