大型双水内冷汽轮发电机定子铁心通风方式

Ventilation Way of the Stator Core of Large-size Double-water Inner-cooled Turbine Generators

以大型双水内冷汽轮发电机为研究对象,对发电机定子铁心采用全出风、抽风式、两进三出和五进六出等四种通风方式的通风特性、铁心温升进行比较,为新产品设计和开发提供参考。

Taking the large-size double-water inner- cooled turbine generator as an example, the ventilation feature and core temperature-rise of four types of ventilation way, single discharge zone, single intake zone, two intakes/three discharge and five intakes/six discharge, were compared, to provide the reference for the design of new products.
