铁路新型接地材料性能分析和应用

随着铁路建设和运营水平不断的提高,特别是客运专线和高铁线路的大量投产,使得原有接地系统在实际运用过程中逐渐暴露出如接地材料、电气指标发生严重劣化的问题,由此影响到铁路运输的正常秩序。将以上问题进行分析,并介绍镀铜护套材料在京沪高铁通信铁塔防雷接地中的成功应用。

Performance Analysis and Application of New Type Railway Earthing Materials

The stability and reliability of railway earthing system will directly affect the safety of railway communication, signalling, electricity, locomotive, human, etc. With the continuous improvement of railway construction and operation level, especially more and more DPLs and hish-speed railways are under construction, problems of exiting earthing system are exposed gradually during actual application, such as serious degradation of earthing material and electric indices. As a result, normal order of railway transportation is influenced. So, this article will analyze above problems, and introduce the successful application of protection jacket material of copper plating in lighming protection and earthing system of communication tower in Beijing-Shanghai high-speed railway line.
