摘要:
为解决川中浅丘地形高速铁路引入枢纽（地区）时电分相合理设置的难题，本文以成达万铁路引入资阳西站为例，针对电分相涉及上下游多专业的特点，构建了“多因素分步研究、多维度综合比选、多工况行车验证”的研究方法，对电分相缓坡设置方案进行研究，得到了满足功能需求、技术可靠、经济合理的技术方案。研究结果表明：（1）新线合场引入车站时，通常由同一相电源对车场内多线供电，末端分区所（电分相）应尽量靠近车站，减小牵引负荷；（2）分相区反向断电标边界里程=车站最外侧信号机里程-(一离去区段长度+三接近区段长度)-0.2km-0.5km；（3）列车限速40km/h通过六跨短分相的最大上坡度为5‰；（4）川中浅丘地形下，分区所选址不作为控制电分相设置的主要因素；（5）枢纽（地区）内，电分相设置应统筹考虑规划线路的引入，避免规划线路实施时对既有铁路相关工程造成严重影响。研究成果可为类似工程提供借鉴和指导。
Abstract:
To address the challenge of rational setting of phase break when leading high-speed railways into terminals（areas）in shallow hilly terrain in central Sichuan，this paper took leading Chengdu-Dazhou-Wanzhou Railway into Ziyang West Station as the case for study，constructed a method of“multi-factor step-by-step study，multi-dimensional comprehensive comparison and selection，and verification by train operation under multiple working conditions”according to the characteristics of phase break involving upstream and downstream disciplines. It also studied the setting scheme of phase break gentle slope，and obtains a technical scheme that meets functional requirements，is technically reliable and economically reasonable. Key findings include：（1）When a new railway line is led into a station，the same phase of power supply usually supplies power to multiple lines in the yard. The end section post（phase break）shall be as close as possible to the station to reduce the traction load. （2） Boundary chainage of reverse power-off sign in neutral section= chainage of outermost signal at the station - length of first departure and third approach sections - 0. 2 km - 0. 5 km. （3）The train passes through the six-span short neutral section at a speed limit of 40 km/h，and the maximum up gradient is 5‰. （4）Under the shallow hill topography in central Sichuan，zoning site selection is not the main factor controlling the setting of phase breaks. （5）In the terminal（area），leading planned lines shall be considered as a whole for the setting of phase breaks，so as to avoid serious impact on related works of existing lines during the construction of planned lines. These findings can provide reference and guidance for similar projects.
