既有线电气化铁路接触网改造技术

Catenary Transformation Technology of Existing Electrified Railway

随着铁路线路里程不断增加,现有铁路干线由于坡度大、曲线半径小、安全性能无保障等因素,已不能满足高速行驶与大吨位荷载机车牵引的现实需求。为此,必须要改造既有线电气化铁路接触网,以提高现有铁路运输能力;与此同时,还要采用电气化铁路系统装置来代替老旧化铁路系统装置,从而不断完善电气化铁路运营技术。系统研讨和分析现有铁路接触网的改建技术要求,旨在为类似项目提供参考。

With the continuous increase of railway mileage, the existing railway trunk can no longer meet the practical needs of high-speed driving and locomotive traction with large tonnage load due to the factors such as large slope, small curve radius and no guarantee of safety performance. Therefore, it is necessary to transform the existing electrified railway catenary to improve the transport capacity of the existing railway. At the same time, electrified railway system devices should be used to replace the old railway system devices, so as to continuously improve the electrified railway operation technology. This paper systematically discusses and analyzes the technical requirements for the reconstruction of the existing railway catenary in order to provide reference for similar projects.
