| Abstract: | A method, finding the steady three dimensional temperature field in rotor slot region for turbogenerator by finite elements is presented, and the rotor slot region temperature of 300MW turbogenerator with rotor hydrogen cooling is calculated in this paper. The analysis calculation indicates, that axial temperature in slot region of rotor, using axial-radial ventilation and subslots, for turbogenerator with rotor hydrogen cooling can be divided and stepped. A radial ventilation hole section as element is calculated and investigated. The highest temperature distribution in the rotor slot section of 300MW turbogenerator is taken as example to be calculated in this article. |
