Abstract
This paper begins with the analysis of the protection range of lightning rod and lightning current, focusing on the discussion of the metal wire frame around the down lead,formed with wires of communica-tion stations and the grounding system.The calculating result shows that the greater the lightning peak value,the shorter the wave front time,the nearer the metal wire frame with the lightning spot and the more likely the electrical device is compromised.If the metal wire frame works as the common ground of the lightning proof,the protection,working circuit,and the ground potential of the common ground fail to be equal everywhere due to the high voltage induction such as lightning with the fluctuations of voltage ranging from hundreds to thousands of volts,undermining electrical devices in the communication stations, especially the disruption of logic integrated circuit,the crash of CPU and hardware damage.The conclu-sion shows that the quantitative analysis of the paper provides a reference basis for the design of the thun-der prevention of communication stations.关键词
