【Abstract】 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 presented in order to make further improvement of the ventilation system.更多还原
