| Abstract: | A three dimensional temperature field model of hydroelectric generator stator is established in this paper. Through taking the half gear and the half groove as calculation area, the temperature field of hydroelectric generator stator of bulb tubular turbine of 5500 kW and 6471 kVA is calculated by using the finite element method. The temperature field of the stator is obtained, and the points and the distribution of the highest temperature of the components are found. The average temperatures of the stator pedestal and yoke are calculated to provide references for the generator design. |
