定子铁心松动问题的分析及处理

Analyses and Treatment for Stator Iron Core Looseness

主要介绍大型水轮发电机组定子铁心产生振动的原因,并通过实例进行分析,确定是由于定子铁心的振动致使定子铁心松动。同时提出解决措施,对于铁心各部位松动进行相应的处理。

This paper mainly introduced causes of vibration of stator iron core in large hy- droelectric generator set, and analyzed by some examples, then it can be conformed that loose- ness of the iron core is caused by vibration of the stator iron core. Solution is proposed at the same time, proper treatment is processed to loosened parts of the iron core, then the vibration problem is solved.
