丹江水电厂3号发电机通风系统改造

Reformation of the ventilation system for No. 3 generator in Danjiangkou Hydraulic Power Plant

温度是发电机安全运行最主要的技术指标之一,它的高低将直接影响发电机绝缘及其寿命,现在许多电厂都普遍存在发电机温度过高(特别在夏季)的问题。为了保证发电机安全运行,发挥最大效益,对发电机通风系统进行改造势在必行。丹江电厂对其3号发电机原有通风系统进行的改造,从改造后的效果看,降温十分明显。

Temperature is one of the main technical indices for generator safe operation. The temperature directly influences the insulation and the life of generator. At present, the occurrence of high generator temperature exists popularly in many power plants particularly in summer. In order to ensure the safe operation, the reformation is extremely necessary. In this article, the reformation of the old ventilation system for No. 3 generators in Danjiangkou Hydraulic Power Plant was mainly introduced. The effect had shown that the temperature was decreased significantly.
