摘　　要：本文依据阻抗匹配平衡变压器的电磁变换关系，论证了三相变换为两相的等值电路，并利用该等值电路，讨论了该变压器的短路电流和压降计算以及无功补偿的分析，所得结果与模型试验以及样机测试对比一致。与传统的星三角接线牵引变压器的相应数据对比，进一步证实了本新型平衡变压器的技术经济优越性。Based on the electromagnetic transformation relationship of impedancema ngbalance transformer,this paper has expounded the three-phase to two-phase transformationequivalent circuit.Using the equivalent circuit,the paper has also discussed the calculation of short circuit current,voltage drop,and analysis of reactive compensation,The results hecalculation are consistent with the test results of the model and the sample transformer.When compared with the relevant datum of traditional Y/△ connection traction transformer,the technical and economical advantage of the new type balance tranformer can be furtherconfirmed。
