【摘要】 针对城市轨道交通牵引供电系统利用走行轨回流而产生杂散电流的问题,结合DC 1500V供电制式供电距离长、电压损失小的优点,提出采用DC 1500V四轨技术来彻底解决杂散电流产生的问题。对DC 1500V系统的技术方案、工程应用可行性和投资影响等进行了深入研究,并得出DC 1500V四轨系统在城市轨道交通工程中的应用是完全可行的结论。更多还原

【Abstract】 Tows the power supply system in view of the URT transportation to use the rails backflow to have the stray currents question,unifies the DC 1500V power supply service pattern power supply to be away from long,the voltage drop small merit,proposed uses the DC 1500V fourth rail technologies to come the question which the thorough settlement stray currents produces. To the DC 1500V system technical plan,the project application feasibility and the investment influence and so on have conducted the thorough research,and obtains the conclusion DC 1500V fourth rail systems in URT engineering application is completely feasible,the application prospect is broad.更多还原
