摘　　要：本文中作者针对一台50MVA/110k V电力变压器产品,设计了四种绕组冷却结构,基于有限体积法对其流场和温度场进行了计算,通过场协同理论对这四种冷却结构的散热特性进行了分析,研究了提高绕组区域散热性能的机理。Four different winding cooling structures for a 50MVA/110kV power transformer products are designed. The flow field and temperature field are calculated based on the finite volume method. The heat dissipation characteristics of the four cooling structures based on the field synergy theory are calculated and analyzed. Ihe mechanism of the heat dissipation in the winding area is studied.
