Advances in modern science and technology , human exposure to the era of network , communication , on the one hand to improve the efficiency of communication exchanges and office , the other hand, the increasing dependence on communication equipment . Information devices dielectric strength and low tolerance of over-voltage and over-current sensitive to electromagnetic interference weaknesses , they are vulnerable to lightning over- voltage and other operating voltage surge damage . Therefore, the study of lightning hazards and protection of communication system is to improve the communication technology issues need to be resolved . The lightning hazards information system can be caused huge economic losses , the paper analyzes the law of lightning damage information systems , through the generation of lightning and the lightning hazard analysis , the overall planning of the proposed communication system lightning protection , and described in detail in the information equipotential bonding system lightning protection , lightning directly stroke protection lightning rod protection range calculation , design and ground connections ; lightning in the division of lightning protection , lightning protection zone , SPD protection and power filter design.
