S11-5000/35型箱变相间短路事故分析

Analysis of Inter-phase Short-circuit Accident of S11-5000/35 Box-type Transformer

以某风电场S11-5000/35型箱变发生的相间短路故障为例,对事故原因进行分析与排查,最终确定为相间短路放电,进而提出相应的处理方案和防范措施。

This paper is focused on an exemplary case of inter-phase short-circuit fault encountered by a S11-5000/35 box-type transformer in an actual wind farm,it analyzes and investigates the cause of the accident,and ultimately determines the fault type as inter-phase short-circuit discharge.It then proposes corresponding solutions and preventive measures.
