250MW发电机定子线棒接头缺陷处理方式探讨

Discussion on Defect Treatment of Stator Bar Joints of a 250 MW Generator

针对日立250MW发电机定子线棒的焊接缺陷,采用红外技术检测对接头进行过热处理,取得了显著效果,该工艺为今后同类型发电机组出现类似缺陷提供借鉴。

After the over temperature problem of stator winding soldered joints in a 250 MW HITACHI made generator found by using infrared technology, the treatment of the joints is very successful. This can be used as an example for the similar problem of the same type generators.
