空冷式汽轮发电机并网时的应急干燥方法

Emergency Dry Method of Air Cooling-type Turbo Generator in Incorporating in Power Network

汽轮发电机在开机并网时,经常由于定、转子绕组轻度受潮而导致绝缘不合格,延误开机并网的正常进行。探讨了一种应急干燥方法,解决闭式循环空冷汽轮发电机在开机并网时因绕组干燥问题而导致的绝缘不合格,实现顺利开机并网。

Start-up and incorporating in power network of the turbo generator is delayed owing to slight wetting of the stator and the rotor winding,leading to insulation not qualified.An emergency dry method is discussed.This method can solve the above problem of the closed cycle air cooling turbine generator and make the turbine generator start up smoothly and incorporate in power network.
