摘要
提高移动通信基站雷电防护能力,有效降低因雷灾造成的设备损伤和影响,是移动通信行业一直研究的重要课题。基于传统并联式技术防雷的不足,全面分析雷电入侵移动通信基站的途径、造成的问题与影响,提出改进的措施。采用串联式防雷技术方式,也是现代雷电防护技术发展的方向,在现有接地防雷基础上,引入相应的设备保护装置,并降低对接地网中接地电阻的要求,有利于实施移动通信基站系统全程防护,确保网络正常运行,节省建设投资和维护成本。
Improving the lightning-protection capacity of mobile base stations and effectively reducing th damage caused by lightning,are always the important research topics in mobile communication field.Due to th insufficient lightning-protection of traditional parallel connection technology,this paper gives comprehensive analysis on intusion path and influence of the lightning,including the improvement strategies.Tandem connection is the development direction of modern lightning-protection.Based on the existent grounding system,PROT i introduced.Tandem mode in lightning protection could reduce the requirement of grounding resistance and facilitate the implementation of whole-process protection.Thus it is possible to ensure normal operation of the mobile networ and save the construction investment and maintenance costs.
