摘要
为彻底解决郑许市域铁路直流牵引供电系统杂散电流对沿线重大敏感设施造成的安全隐患,首次在城际轨道交通项目中采用专用轨回流的方式。由此带来的场段检修库牵引网方案有别于传统的走行轨回流模式,对检修库的牵引网提出新的要求。该文结合工程实际,对检修库内回流轨设置及静调电源取流和回流方案进行深入研究,首次提出满足工艺检修要求和牵引供电系统要求的专用轨回流模式下的检修库牵引网方案,全面总结在项目中积累的经验,为今后类似项目起到了指导和借鉴的作用。
In order to completely solve the safety hazards caused by stray current of DC traction power supply system in Zhengzhou-Xuchang Urban Railway to the important sensitive facilities along the line,a special track return method was adopted for the first time in the intercity rail transit project.The traction network scheme of the maintenance depot is different from the traditional running rail return mode,which poses new requirements for the traction network of the maintenance depot.Based on the engineering practice,this paper makes an in-depth study on the return rail arrangement in the maintenance depot and the scheme of taking current and returning current of the static regulating power supply,the traction network scheme of maintenance depot under the special rail reflow mode to meet the requirements of process maintenance and traction power supply system is put forward for the first time,and the experience accumulated in the project is comprehensively summarized,which plays a guiding and reference significancefor the future of similar projects.
