同步电机励磁机高温解决方案研究

Research on High Temperature Solution of Synchronous Motor Exciter

摘要: 同步电机及其励磁机的冷却降温是确保设备正常运转的重要保障。从改造成本、改造难度及温降效果3个方面对增加电机内、外部换热器的换热面积、增加正压通风的通风量、改善励磁机的通风环境3种方案进行了对比，得出改善励磁机的通风环境是最为可行的解决方案，并在实际改造中得以应用，且取得了良好效果。

Abstract: Cooling and temperature reduction of synchronous motor and its exciter were an important guarantee to ensure the normal operation of the equipment. The paper compared three solutions of increasing heat exchange area of internal and external heat exchangers, increasing positive pressure ventilation and improving ventilation environment of exciter. The result indicates that improving the ventilation environment of exciter is a feasible solution and it is used in its actual reconstruction, good result is obtained in application.
