At present,the stator temperature rise,iron core loose and other abnormal problems of the domestic bulb tubular turbine generator stator are common,which seriously affect the normal operation of the turbine generator set,but also greatly increase the daily operation and maintenance workload and maintenance costs.This paper analyzes the problems of stator temperature rise,iron core loosening and silicon steel segment teeth before stator reconstruction of 4MW bulb tubular turbine generator set in Yuejiang Hydropower Station,and describes and summarizes the measures of stator reconstruction in detail.The results show that the transformation has remarkable effect and can effectively solve the above problems.
