城市轨道车辆供电制式的分析研究

摘要

At present, China's urban rail transit system has three kinds of power supply pattern. They are DC 750 V contact rail pattern, DC 1 500 V overhead catenary pattern and DC 1 500 V contact rail pattern. In this paper, comparison has been made between the contact rail pattern and the overhead catenary pattern, the result shows that the DC 1 500 V overhead catenary power supply patten is better and therefore should be developed in the future.%目前,我国城市轨道交通系统的供电制式包括DC750 V接触轨供电、DC 1 500V接触网供电和DC 1 500 V接触轨供电等3种方式.就接触轨和接触网两种供电方式涉及的若干问题进行分析比较,认为DC 1 500 V接触网方式才是真正的发展方向.
