摘　　要：针对阻抗匹配平衡变压器结构因与电力系统传统使用的三相变压器结构不同而导致的对匝数比取值问题的误解,通过对阻抗匹配平衡变压器接线方式、绕阻布置、阻抗设计等方面的分析,得出其匝数比应取槡8,并分析了匝数比取值缪误对牵引变电站接入电网的电能质量评估的影响。Aiming at misconception of turn ratio value caused by structural difference between impedance-matching balance transformer and conventional three phase transformer, the paper analyzes wiring mode, winding configuration, impedance design of impedance-matching balance transformer. It is concluded that the turn ratio should be √8 rather than 4, and the paper also analyzes impact of wrong value of turn ratio on assessment of power quality of gird-connected traction substation.
