Abstract:

Abstract:A higher interlayertemperature fault of stator coil bar of a large turbogenerator was introduced. It was found by analysis that the reason of higher interlayertemperature is the blockage of the stator coil bar. The composition of the blockages and the reason of the blockage were analyzed. The method to clean the stator cooling water system was put forward. After cleaning, the maximum deviation of the interlayertemperature is 2℃, and the fault was eliminated.
