摘　　要：定义了损耗值和热阻值,建立了一个简化的热路模型,利用该模型,构建了变压器顶层、底层油温模型,并在这两种油温模型基础上,建立了绕组热点温度模型,并用模型进行了对比计算。The loss and thermal resistance values are defined. The simplified thermal circuit model is estabilished. The top and bottom oil temperature models are constructed with the thermal circuit model. Based on two types of oil temperature models, the hot spot temperature model of winding is estabilished. They are compared and calculated with the models.

关 键 词：油浸式变压器 热路模型 换热
