摘要
研究了五强溪水轮发电机通风系统的设计方案,通风及温升计算方法,转子支架入口尺寸的选择和转子磁轭环形风沟的选择。通风及温升试验结果表明,该通风系统选择合理,通风和温升计算方法实用准确,可大大提高利用系数。
The paper maily studies the two ventilation structures, the calculating method for ventilation and temperature rise, the choice of inlet dimension of rotor frame and the choice of the annular duct on rotor magnetc joke. It is proved by ventilation and temperatane rise tests that the ventilation system option is reasonable and the calculation method for ventilation and temperature rise is practical and exact. The availability factor can be increased.
