中德两国高铁接触网设计主要参数对比研究

Comparative Research on Main Design Parameters of High-speed Railway OCS between China and Germany

德国是高铁技术原创国之一,承担了铁路国际标准大量的编制工作,通过对中德两国高铁接触悬挂类型,承力索、接触线及其工作张力,最短吊弦与结构高度,跨距,受电弓宽度与接触线允许风偏,受电弓动态包络线等11大项接触网设计主要参数的对比研究发现,接触网参数之间有着密切的联系,仅从某项参数的数量大小比较得出结论是不客观、不全面的;中德两国之间大部分设计参数取值相当;中国接触网标准承力索、接触线截面尺寸和工作张力较大,受电弓动态包络线范围较大,与《跨国境行驶列车的动态包络线》UIC 505-1不一致,应结合技术标准的制修订工作对此进行专题研究试验。

Germany is one of the original countries of high-speed railway technology, and has undertaken a lot of work in the preparation of international railway standards. Through the comparative study of 11 main parameters of catenary design, such as contact suspension type, catenary, contact line and its working tension, shortest suspension string and structure height, span, pantograph width and allowable wind deflection of contact line, dynamic envelope line of pantograph between China and Germany, it is found that, there is a close relationship between catenary parameters. It is not objective and comprehensive to draw a conclusion only from the comparison of the number of certain parameters;Most of the design parameters between China and Germany are equivalent;The section size and working tension of catenary and contact wire in China are large, and the dynamic envelope range of pantograph is large, which is inconsistent with UIC 505-1, DYNAMIC ENVELOPE OF CROSS BORDER TRAINS. Therefore, special research and test should be carried out in combination with the formulation and revision of technical standards.
