[Abstract]Its application is becoming more and more extensive and the scope of application is becoming larger and larger. At the same time, the requirements of the pantograph catenary system are constantly improving, and the influence of the pantograph catenary system on the electric locomotive in China has also been widely valued. Therefore, it is of great significance to improve the quality of electrified railway catenary and create a good environment for pantograph catenary system to ensure the safe and stable operation of electric locomotive. Based on this, this paper first analyzes the factors and influence of electrified railway contact hard point, and puts forward effective improvement measures on this premise, hoping to improve the overall quality of electrified railway contact hard point.

对电气化铁路来说,其运行质量和效率同弓网系统关系密切,为了能够提高电气化铁路运行的稳定性和安全性,加强对弓网的重视十分必要,通常情况下始终保持弓网接触压力不变,这样才能确保其为电动机车提供有效的电能,然而在实际运行环节,接触网形成的压力并不是一成不变的,极易受到其他的因素影响发生变化,其中硬点便是一大影响因素。硬点问题的出现对电气化铁路接触网运行的安全性和稳定性造成严重的影响,同时对电气机车的平稳运行有较大的影响,所以为了提高运行整体质量,则需要对电气化铁路接触网硬点问题进行全面分析,进而采取有效的改进措施。
1 电气化铁路接触网硬点概述
对电气化铁路来说,接触网是指一种被广泛应用于受电弓稳定取流的高压供电线,具有一定的特殊性和复杂性,其主要作用是保障对电力机车的供电功能。……
