Oil-immersed forced oil circulation with natural cooling 自然冷却油浸式强制油循环
This paper sets up the mathematic model of heat transfer and oil flow, and finishes the calculation of oil flow distribution and temperature field of winding in large natural oil circulation power transformer with oriented cooling structure. 本文建立了传热与流动数学模型,完成了大型自然油循环导向冷却方式变压器的油流分布和绕组温度场计算。
The Calculation Research of Temperature Rise of Large Natural Oil Circulation Power Transformer with Directed Structure with the Means of Natural Air Cooling and Forced Air Cooling 大型自然油循环导向结构变压器自然风冷却和强风冷却温升计算研究
The direct consequence of adopting oil natural oil circulation cooling is increase of temperature between copper and oil, so transformer cooling problems become more and more prominent. 采用自然油循环冷却方式的直接后果是铜油温差加大,变压器的散热问题更加突出。
