摘　　要：分析了Scott结线形式的平衡牵引变压器的电磁结构,建立了变压器的三维有限元模型,求解出了变压器短路阻抗。通过对比变压器短路阻抗理论计算值、仿真值和试验值,验证了变压器理论设计的正确性。The electromagnetic structure of balance traction transformer with Scott connection is analyzed. The three-dimensional finite element model of the transformer is established. The short-circuit impedance of transformer is solved. By comparing the theoretical calculation value, simulation value and test value of transformer short-circuit impedance, the correctness of transformer theoretical design is proved.
