架空接触网与三轨不停车切换过渡的技术探讨

广州地铁四号线正线采用DC1500V三轨受流制式,车辆段采用架空柔性悬挂接触网受流制式,架空接触网与三轨并行运营,对于架空接触网与三轨之间切换提出了较高的技术要求,本文通过研究我国广深线高速铁路自动过分相方式,对不停车切换方式进行技术分析,为四号线的建设提供参考。

The main line of Guangzhou Metro No. 4 Line adopts the third rail fed by DC 1 500 V power supply system and the depot adopts flexible suspension OCS current collecting mode. Because OCS and the third rail are operated cooperatively, the requirements of switching between OCS and third rail will be much higher. This article studies automatically passing neutral section mode of Guangzhou-Shenzhen high speed railway line and analyses non-stopping switching technology, settling a foundation for the reference of building No. 4 line.
