京九线孔垄牵引变电所电分相改造方案研究

Research on Upgrading of Phase Splitting of Konglong Traction Substation of Beijing-Kowloon Railway

京九线既有孔垄牵引变电所电分相为六跨关节式电分相,由于安庆至九江高速铁路孔垄联络线引入既有孔垄站,为满足开行动车组列车运行的技术条件需求,需对既有孔垄牵引变电所电分相进行改造。以对既有运营干扰最小以及改造工程量最小为原则,经过方案比选,推荐采用上下行电分相对齐及移动距离最短的方案,实现满足开行动车组运行的技术条件,并给出了可行的改造方案,为安九高速铁路引入既有京九线动车组的开行提供了技术保证。

The phase splitting of Konglong traction substation in Beijing-Kowloon Railway is 6-span catenary.Due to the Anqing-Jiujiang high-speed railway is connected to the Konglong station,and in order to meet the technical requirements of EMUs operation,it is necessary to transform the phase splitting of Konglong traction substation.To reduce the interference on the transportation and the work volume,it is recommended to adopt the scheme of the phase splittings at the same mileage and the shortest moving distance from the existing mileage.The scheme satisfies the technical requirements of EMUs operation,and gives the feasible reconstruction plan,which provides the maintenance logistics for running EMUs on Beijing-Kowloon Railway.
