大型水轮发电机通风发热综合计算

以大型水轮发电机热变形及冷却技术研究为背景，进行了大型水轮发电机转子三维温度场及电机通风系统的综合计算研究，以往在进行大型水轮发电机发热分析时，都是孤立地球解温度场，而很少考虑热源及通风结构与温度及其分布之间的相互影响，文中采用一种综合算法，将电机通风发热联系起来，该研究工作对于提高电机设计制造中材料利用率以及电机运行中的可靠性，具有重要意义。

SYNTHETIC CALCULATION FOR THE VENTILATION AND HEATING OF LARGE WATER WHEEL GENERATOR

This paper takes the thermal deformation research and cooling technology of a large water wheel generator as background, and makes a synthetical calculation of the three dimensional temperature field and the ventilation system of the rotor of an electric machine. In the past, when the heating problem of a large water wheel generator was concerned, the temperature field was individually solved regardless of the interactions among thermal source, ventilation structure, temperature and its distribution. In this paper, a synthetical algorithm related to the ventilation and heat of an electric machine is adopted. The research work in this paper is very important to raise material utilization during the machine design and manufacture and reliability during the operation of the machine.
