1.前言由于接触网是露天设置,没有备用,使用条件恶劣,所以其安全性对行车而言就显得举足轻重。而最常见的接触线的偏移值在运营维修中成了保证运输安全的首要条件。《铁路电力牵引供电设计规范》第4.4.5条规定:“在最大计算风速条件下,接触线距受电弓中心的最大水平偏斜值,一般地区不得大于500mm,与大风方向一致的山口、谷口和高架桥、特殊重要桥以及安装支柱极困难的桥范围内,不得大于450mm。” 2.影响接触线偏移的因素在运行可能的情况下,接触线在水平面
1. Introduction Since the catenary is an open-air setting, there is no backup, the use of harsh conditions, so its safety is very important for traffic. The most common line of contact offset value in the operation and maintenance has become the primary condition to ensure the safety of transport. Article 4.4.5 of “Code for Design of Railway Electric Traction Power Supply” stipulates: “Under the conditions of maximum wind speed calculation, the maximum horizontal deviation of the contact pantograph center from the pantograph center shall not exceed 500mm in general and shall be consistent with the direction of high winds , Taniguchi and viaducts, special important bridges and bridges with extremely difficult installation pillars shall not be more than 450mm. ”2. Factors Affecting the Contact Line Offset When possible, the contact line is in the horizontal plane
