摘要
本文叙述了灯泡式水轮发电机通风系统的特点,探讨了如何通过调整通风系统结构来保证风量沿轴的均匀分配,介绍了计算电机风量的网络法及计算定、转子各部分温度分布的有限元法,以便在此基础上进行通风系统进一步改进。
The features of ventilation system in bulb hydrogenerators are described in the paper. The approach to adjust the structure of ventilation system to ensure the uniform distribution of the air flow in axial direction, as well as network method in ventilation calculation and finite element method in the calculation of temperature distribution in different parts of the stator and rotor of electric machines are oresented in order to make further imorovement of the ventilation svstem.
