既有线接触网八跨锚段关节电分相改造研究

摘要

随着我国电气化铁路的发展，越来越多的铁路规划、行车速度等不断出现新要求，既有线接触网电分相改造尤为重要，改造后的电分相必须确保没有安全隐患，确保列车的正常运行。本文重点介绍了接触网八跨关节式电分相改造特点，并对既有线接触网八跨锚段关节电分相改造施工工艺进行浅析，对今后的施工有一定的借鉴作用及参考价值。%With the development of electrified railway in our country,more and more railway planning,driving speed ap-pear new demands constantly,such as electrical sectioning device of the existing railway catenary system is particularly im-portant,the transformed electrical sectioning device must be ensured that there is no hidden danger and train can work as u-sual.This paper mainly introduces the transformation characteristics of the eight-span overlapping electrical sectioning de-vice,and analyzes the renovation construction technology of the eight-span overlapping electrical sectioning device of the ex-isting railway catenary system.It has some reference values for the construction in the future.
