| Abstract: | In this paper,the thermal conduction equation and functional equation of a large hydrogenerator under the cartesian coordinate system are presented.The 3D isoparameteric element method is applied to computer the stator temperature fields with interturn insulations considered.And the stator temperature field is analyzed by numerical simulation method and some useful conclusions are drawn when the hydrogenerator running long time and the influences of one of up and down layer interturn insulations aging is considered. |
