The invention relates to a traction current and traction backflow composite channel which comprises a traction current channel composed of a plurality of metal wires. The traction backflow channel is composed of a plurality of metal wires, the traction backflow channel is evenly arranged on the periphery of the traction current channel, and the current direction of the traction current channel is opposite to that of the traction backflow channel; the insulating layer is arranged between the traction backflow channel and the traction current channel, uniformly coats the outer surface of the traction current channel and is uniformly attached to the inner surface of the traction backflow channel; according to the invention, the positive cable and the negative cable are integrated in the composite channel, and the advantages that the current directions of the positive cable and the negative cable are opposite and the distance is short are utilized, so that the electromagnetic induction of the positive cable and the negative cable can offset each other, and the electromagnetic induction influence range is greatly reduced; and the electromagnetic influence of the traction network on surrounding electrical equipment is fundamentally reduced.
本发明涉及一种牵引电流和牵引回流复合通道,本发明包括牵引电流通道,其由多根金属导线组成;牵引回流通道,其由多根金属导线组成,牵引回流通道均匀设置在牵引电流通道的四周,牵引电流通道和牵引回流通道的电流方向相反;绝缘层,其设置在牵引回流通道与牵引电流通道之间,绝缘层均匀包覆牵引电流通道的外表面,且均匀贴附牵引回流通道的内表面;本发明通过将正极电缆和负极电缆集成在一个复合通道内,利用正极电缆和负极电缆电流方向相反且距离近的优势,正极电缆和负极电缆的电磁感应不仅可以相互抵消,还大大缩小了电磁感应影响范围,从根本上降低了牵引网对周围电气设备的电磁影响。
