地铁延长线机电系统接入方案探讨

Discussion on connection of electromechanical system on metro extension line

以珠江三角洲城际快速轨道交通广州至佛山段二期工程为例,针对地铁延长线接入既有线路涉及到的轨道、供电、通信、信号、隧道通风、综合监控、自动售检票等方面,对其机电系统的接入方案进行探讨。为确保系统接入对既有线路运营影响最小,轨道以冻结接头形式接入,供电环网电缆在预留的中压出线柜内接入,接触网以非绝缘锚段关节的形式接入,通信传输系统以割接形式接入单环传输网,电话和无线通信系统通过软件扩容形式接入,信号系统采用独立联锁区的形式接入,隧道通风系统通过修改系统运行模式接入,综合监控和自动售检票系统通过中央级软件扩容升级接入。

Taking the second phase project of Guangzhou to Foshan intercity transit as an example,this paper describes the access connection of electromechanical system on the metro extension line with the track,power supply system,communication,signaling,tunnel ventilation,integrated supervisory control system,automatic fare collection etc.In order to minimize the impact on the operation of existing lines,all the mechanical and electrical system adopts the optimal access plan.
