摘　　要：由于不对称接线平衡变压器绕组结构较为特殊,其短路阻抗需要满足特定约束条件,设计时短路阻抗参数尤为重要.利用有限元软件对不对称接线变压器进行有限元分析,进行三维静磁场仿真.将电磁仿真结果与电磁计算结果进行比较,验证了变压器电磁设计的正确性,为变压器的设计制造提供了理论依据.The structure of unbalanced connection transformer is special,and its short-circuit impedance needs to meet the particular constraint condition.The design of short-circuit impedance parameter is especially important.In this paper,the finite element analysis of the asymmetrical connection transformer is carried out to simulate the three-dimensional static magnetic field.By comparing the electromagnetic simulation results with the electromagnetic calculation results,the correctness of the electromagnetic design of the transformer is verified and the basis for the design and manufacture of the transformer is provided.
