【Abstract】 In this paper, the three dimensional temperature field of the hottest region in the stator of hydroelectric generator is calculated by means of finite element method, in which the wire insulation on the stator winding is considered or not considered. The calculated results of 320MW and 150MW hydroelectric generator are given, and the effect of wire insulation on the stator winding is analysed.更多还原
