| Abstract: | The excessive temperature difference of generator stator bar seriously affects the safe operation of the generator.Through the cause analysis on the excessive interlayer and effluent temperature difference for the 600 MW generator in Lanxi Power Plant,the treatment measures are adopted such as generator bar pipe cutting for inspection,generator stator bar pickling,stator cooling water pH value improvement,sealing transformation of stator cooling water tank etc.to solve the problems of excessive generator temperature difference and stator cooling water flow decrease.It can serve as a reference for other power plants with similar problems. |
