复线AT牵引网上下行反相供电新方式

我国常规的复线AT牵引网结线方式为上下行并联供电。所谓上下行反相供电，是指上下行线馈线供电电压有180。相位差，即上行T线与下行F线并联，而上行F线则与下行T线并联。这种供电方式对AT牵引网技术经济指标可产生重大影响。本文对反相供电的特性进行了全面分析，对其可行性进行了评估.

A New Method of Reverse Phase Power Supply System on Up and Down Lines in Double Line at Traction Network

In standard scheme of double line AT feeder system, the feeders of two tracks are connected parallelly at each AT post. In this paper a new method of opposite phase connection of feeders in up and down traction network is suggested, and a technical analysis and feasibility study is carried out.
