铜街子水电站发电机定子铁芯电腐蚀处理

Treatment on electric erosion of generator stator core in Tongjiezi Hydropower Station

阐述了铜街子水电站发电机定子压指脱焊、铁心波浪度增大、铁芯电腐蚀产生的原因,以及处理措施和处理效果。

The mechanical vibration caused the pressure finger of the generator stator core off-welded and the stator core unfastened.Thus,the stator core was spoiled by electric erosion and its waviness increased noticeably.The treatment measures and practical result for these faults are described.
