探讨普速铁路、高速铁路及地铁三者牵引供电系统的联系与区别。首先从供电方式、变压器、牵引变电所接线及保护配置4个方面介绍普速铁路、高速铁路和地铁的牵引供电系统,然后综述其关键技术发展历程,并在此基础上分析总结三者牵引供电系统的联系与区别。最后指出牵引供电技术未来发展方向。
This paper discussed the connections and distinctions of three kinds of traction power supply systems of universal speed railway, high - speed railway and metro. First, these three kinds of traction power supply systems were analyzed from the perspectives of power supply, transformers, traction substation connection and protective configuration. And then, key technology developments of traction power supply systems were summarized as well as the connections and distinctions among the three kinds of traction power supply systems. Finally, the trend of traction power supply technology was presented.
