摘　　要：本文结合工程实际，对大型水轮发电机转子三维温度场求解进行了研究，包括求解区域的确 定、剖分及计算中应考虑的实际问题、边界条件的确定及计算数据的前后处理，并以漫湾电 站SF250-48/12200型水轮发电机为例进行了试算，与实测数据对比表明，计算结果符合工 程实际。Solving 3D temperature field for the rotor of a large hydrogenerator is c oncerned in the paper,including determining the evaluating area,the practical p roblems in the meshing and the calculation,the boundary conditions,pre and post pr ocessing for the calculating data.The hydrogenerator SF250-48/12200 in M anwan Power Station is taken as an example to make the calculation.The contrast of the values between the calculation and the experiment shows the calculating r esults are suitable to the engineering practice.
