平衡变压器阻抗匹配系数与产品性能关系研究

Study of Relations Between Performances of Products and Impedance-Mathching Coefficient of Balance Transformers

阻抗匹配系数是平衡变压器的一个重要参数,它的不同取值与产品性能有直接关系.本文对比分析了阻抗匹配系数分别为2.732,1.0和0.2128时,平衡变压器产品的材料利用率、副方三角形绕组阻抗压降以及副方两相电压降落等性能指标,指出平衡变压器性能最佳时的阻抗匹配系数是2.732.

The ImpedanceMatching Coefficient (IMC),concerned with the performances of products,is the important parameter for balance transformers. Such performances as the utilized efficiency of materials,secondary impedance voltage drops of deltoidal windings,and secondary twophase voltage drops for balance transformers were analysed when the IMC is 2.732,1.0 or 0.2128 respectively.The study result indicates that the IMC is 2.732 when performances are the most optimal.
