中型高速水轮发电机设计中的几个问题

Medium High-speed Hydro-generator's Design Practice and Prospect

列出了国内有代表性的8个规格的中型高速水轮发电机的主要数据,指出了宜利用该类发电机通风良好的特点而在电磁设计时选用较大的定子线负荷和槽电流,绘出了这类发电机的电机利用系数、定子极距、定子线负荷和定子槽电流的选择范围,以及介绍了转子结构与推力轴承的性能数据。

The paper presents main datas of domestic typical medium high-speed hydrogenerator, and suggests selecting large line load and slot current of stator, so that the good ventilating feature of this kind of generator can be applied. The paper also gives out the selecting scope of this generator's utilization factor, stator pole distance, stator line load and stator slot current, as well as performance data of runner structure and thrust bearing.
