Introduction to railway GSM - R base station lightning protection Liu Hui-qiong CR11G Electric Engineering Co.,LTD,
Abstract:Nowadays, with the increasing speeding up of urbanization process, the development of the high speed railway attracts the world’s attention. The GSM-munication system as the main means munication used in passenger dedicated line, its application is more and more popularity. But considering the issues of the land resources conservation and maintenance considerations In the practical application, the GSM - R base station has often been affected by a lightning strike. The problem that how to make the anti-lighting reliably is worthy of railway builders’attention and care. This article gives the detailed analysis and solutions to solve the above problems.
Keywords:high speed railway; GSM - R; anti-lighting
随着我国铁路大建设的兴起,GSM-R系统逐渐覆盖了整个国内铁路市场。青藏铁路、胶济铁路、郑西铁路、武广铁路等多条铁路通信系统中均引入了GSM-R系统。与此同时,GSM-R系统逐渐成为了铁路通信工程的重中之重。随着该系统的应用普及,我们发现其基站频频受到雷击影响,对铁路的安全运行极为不利。
一、铁路GSM-R基站雷灾原因
铁路GSM-R基站与电信部门的通信基站不同,它们只需要对铁路通过的地方全方位覆盖即可。目前,由于考虑到征地及维护等因素,基站的选址大多选在线路附近,因此局限性较强。甚至有些基站建在了雷击频发区,从而使雷击事故多有发生。
部分铁路项目盲目赶工期,在GSM-R基站建设完成后未能够做好相应的防雷设施便直接投入运行。同时,这部分GSM
