摘要
道岔上方的接触网布置是铁路电气化系统安全运行的重要环节,本文从道岔处接触导线定位入手,针对山区构造物多、桥隧比例大造成的空间有限等外部条件,对高速电气化铁路18号道岔上方接触导线非传统布置方式进行研究;比较分析道岔上方交叉布置方式与无交叉布置方式类型及特点;以道岔区域接触导线布置基本原则为依据,通过接触导线拉出值、跨距、风速等因素逐步分析道岔定位支柱非传统情况下的布置范围,以提供18号道岔处接触网定位多样性方案。
The arrangement of overhead contact system above turnout is an important link in the safe operation of railway electrification system.This paper starts with the positioning of the contact wire at the turnout.For the external environment conditions such as the large number of structures in the mountainous areas and the limited space caused by the large proportion of bridges and tunnels,the non-traditional arrangement of contact wires above the 18 turnout of high-speed electrified railway is studied.The types and characteristics of cross-arrangement and non-intersection modes above the turnout are compared and analyzed.Based on the basic principle of contact wire arrangement in the turnout area,through the contact wire pull-out value,span,wind speed and other factors,the layout range of the ballast positioning struts in the non-traditional situation is gradually analyzed to provide the contact diversity positioning scheme of the 18 turnout.
