电力变压器温升与冷却装置改造的技术经济分析

The Economic and Technical Analysis of Amelioration in Power Transformer Temperature Rising and Cooling Device

通过分析电力变压器对散热和温升的控制要求,结合一台变压器的冷却装置更换改造实例,对新旧冷却装置降低电力变压器温升,提高负载能力,节约电能损耗等进行技术经济的对比分析。

In this paper, the requirements of power transformer to cooling and temperature rising are analyzed. As a practical example, the cooling device of a power transformer is updated. The new and old cooling devices are analyzed comparatively in reducing the transformer temperature rise, increasing the power loading and reducing the power loss.
