| 摘 要： | 本文根据阻抗匹配平衡变压器ＡＢＣ三相结构不对称的特点，采用相分量法推导了当牵引负荷母线侧出现各种短种故障时，三相侧与二相侧的短路电流计算公式，实测结果证明了计算公式的正确性，这对阻抗匹配平衡变压器的设计，运行过程中的故障分析以及继电保护动作参数的整定具有一定的理论意义与实用价值。

| Abstract: | Considering the unsymmetrical characteristic of the ABC threephase constructure of the impedance-matching balance transformer and adopting the phase components method, the short-circuit calculation formulae of three-phase and two-phase sidesare deduced in the paper when all kinds of practical short-circuit failure appear at thetraction busbar side. The correctness of the formulae is verified by test results. Theconclusions of the paper have theoretical significance and practical value in the design,the failure analysis during operation and the setting of relay protection of the impedance-matching balance transformer. |
