摘要：

介绍了VX接线牵引变压器的接线特点;推导了二次绕组容量不相等情况下的VX牵引变压器的节点导纳阵;分析计算了当二次绕组容量的比值发生变化时负序分别对系统的影响,并对结果进行分析总结得到了一般性规律。

关键词: VX接线, 不等容, 节点导纳阵, 负序

Abstract:

The design characteristics of VX connection traction transformer are introduced.The Node admittance matrix of the VX connection traction transformer with the capacity of the Secondary side different are deduced.The influence of negative sequence of the system with the ratio of secondary side capacity change are analyzed and calculated separately and the general rules are Summed up by analyzing and summarizing the results.

Key words: VX connection, unequal capacity, node admittance matrix, negative sequence
