摘　　要：以一台高阻抗变压器为研究对象,通过理论计算及三维有限元法分析了两种磁分路的磁密分布,研究了两种磁分路对油箱温升的影响,并将有限元计算结果与试验值进行了对比分析。Taking a high impedance transformer as the research object, the magnetic density distribution of two kinds of magnetic shunt is analyzed by theoretical calculation and 3 D finite element method, and the influence of two kinds of magnetic shunt on the temperature rise of oil tank is studied. The results of finite element calculation are compared and analysed with the experimental values.
