灯泡贯流水轮发电机二次循环冷却技术的探讨

Inquiry into Twice Cycle Cooling Technique for Bulb Hydrogenerator

国外一些水电设备制造厂采用二次循环冷却技术对大型灯泡贯流水轮发电机进行冷却,获得了良好的效果。二次循环冷却在国内尚在应用和探索中,本文对二次循环冷却技术中的通风散热结构、计算以及如何利用冷却套进行热变换一系列技术问题作了详细的介绍。

Some hydroelectric equipment works abroad, cooling large bulb hydrogenerator by use of twice cycle cooling technique, got a good result. The technique is being applied and studied at home now. A series of technical questions, such as construction of ventilation and heat-dissipating heat elements, their calculation as well as how to do heat exchange by using cooling jacket, are introduced in detail in this paper.
