摘要
用三维有限元方法讨论了汽轮发电机定子线圈和铁芯的温升分布,计算了损耗、通风和表面散热系数,并给出了计算区域内的三维温度分布图。
The temperature rise distribution problem in stator winding and core of turbine- generator are discussed by the use of three-dimensional finite element method in this paper. The losses, ventilation and surface heat-dissipation coefficient are calculated. Three-dimensional temperature distribution plots in calculated area are given.
