摘要
架空刚性接触网作为传输列车牵引电能的载体及受电弓滑动取电的机械滑道,是市域快线供电系统的重要组成部分.为保证其能够持续、稳定、可靠地向列车传输电能,文章以国内第一条采用架空刚性接触网授流、速度高达160 km/h的全地下市域快线——广州地铁18号线为例,在分析其架空刚性接触网设计要求的基础上,采用理论计算、有限元仿真等技术手段对架空刚性接触网设计方案进行全方位研究,确定悬挂方式、导高、标准跨距、锚段长度、拉出值布置方案,以及分段绝缘器、膨胀元件及弹性线夹等关键设备的选型要求,并通过仿真及工程实例验证设计方案的有效性,以期为类似工程提供参考和借鉴.
Abstract
As a carrier for transmitting traction power and a mechanical slide for train pantograph power collection sliding,the rigid overhead contact system(rigid OCS)is an important part of the power supply system for urban express lines.In order to ensure the continuous transmittance of electric power to trains,both stably and reliably,this article explores the first fully underground urban express line with a 160 km/h operating speed in China that adopted rigid OCS to transmit electric power,Guangzhou metro line 18.Based on the analysis of the design requirements of rigid OCS,a comprehensive study of the design scheme of rigid OCS is conducted by using theoretical calculations,finite element simulations,and other technical means.This allows the determination of the suspension mode,height of the conductor,the suspension span,the tensioning section length,the stagger layout,as well as the selection requirements for key components,such as section insulators,expansion-elements,and cable-cleats.In addition,the availability of the design scheme is verified through simulation and engineering cases,with the goal of guiding similar cases.
