500kV变电站主变压器风冷装置跳闸的原因分析及处理

Cause Analysis and Treatment on 500kV Substation Main Transformer Air-cooled Device Tripping

对一起500kV变电站主变压器风冷装置跳闸故障进行分析,认为控制回路绝缘降低是风冷装置跳闸的主要原因,提出相关的处理措施及防范建议。

This paper introduces a 500kV substation main transformer air cooling device failure,analyzes and considers that the main reason of the air-cooled unit tripped is the reduced control loop insulation,and proposes measures to deal with failure and prevention recommendations.
