Application of Traction Unit with Non-polar Rope in Gaocheng Colliery

无极绳牵引车在告成矿的应用

DC-01 direct current locomotives of Shanghai Metro line one were imported from Germany. The driver locomotives were drove by direct current motors with the speed regulation method of chopper. TCUs ( Traction Control Unit) and choppers are the main controllers of the driver locomotives.

上海地铁一号线DC-01型直流机车系德国进口，其中动车采用直流电机驱动，利用斩波器进行调速，其主控器为TCU（牵引控制单元）和斩波器。

the resistance braking energy of simulative traction unit is recycled and used effectively using this system.

利用此系统可以对城市轨道车辆模拟牵引单元电阻制动能量进行有效回收，并加以合理利用。

The main contents of the paper include next parts, as following: (1) Explored the whole program of gearless traction oil pumping unit.

本文主要内容包括以下几点：（1）探究了无齿轮曳引式抽油机的整体方案。
