摘　　要：文献 [1]提出部分感应电压系数概念 ,将AT供电系统在通信线上产生的感应电压分解为分别与正馈线位置、AT漏抗 (与间距 )和钢轨漏泄阻抗相关联的相对独立的组成部分。其中 ,决定于AT网络结构和通信线位置的三个关联参数被定义为AT系统的部分感应电压系数。该理论为AT供电系统的防护特性分析提供了便捷而有效的手段。文献 [1]分析了并联复线AT系统的部分感应电压系数 ,现在再分析其处理难度更大的不并联复线AT系统的部分感应电压系数。稍微牺牲一点计算精度 。The inductive voltage on communication wire can be divided into three relatively indepent parts corresponding to the position of positive feeder,the leakage inductance of AT and the leakage resistance between railway and earth respectively [1]. A new concept of componental induction factor [1] is also proposed. And the three corelative parameters determined by the structure of AT network and the position of communication wire are defined as the componental induction factor. This theory gives a convenient methed for analysis of the protect characteristic of AT traction power supply system. The componental induction factor of parallel connection dubleline of AT traction power supply system has been discussed [1]. Unparallel connection doubleline which is more difficult to deal with is discussed in this paper. Though the calculation accuracy is reduced a little,the calculation procedure becomes as easy and simple as the case of parallel connection doubleline.
