胶济客运专线分区所改造设计

Design for Transformation of Section Posts of Qingdao-Jinan Railway Passenger Dedicated Line

以胶济客运专线分区所改造为例,介绍既有柱上开关式分区所改造为箱式分区所的设计,分析既有牵引供电设备情况,结合既有柱上开关式分区所设备分析研究,提出胶济客运专线箱式分区所布置、远动系统接入、供电线设计方案,提高了供电设备的可靠性和方便维护管理,为类似电气化铁路分区所改造提供参考。

This paper, taking the transformation project of section posts of Qingdao-Jinan railway passenger dedicated line as an example, introduced the design of how to transform the existing switching-type section posts into the box-type section posts, and analyzed the situation of the existing traction power supply equipment. Further on, in combination with the analysis and research on the existing equipment of switching-type section posts, this paper suggested the design scheme of the box-type section posts of Qingdao-Jinan railway passenger dedicated line, including how to arrange the box-type section posts, how to connect them to the supervisory control and data acquisition system, and how to configure the power feeders. This design scheme can improve the reliability of power supply equipment and can be convenient for its maintenance and management, serving as reference for the transformation of section posts of similar electrified railways.
