随着社会的不断发展,安防监控在社会中的应用越来越广泛。这些监控设备由于其自身特殊的敏感性,于是对雷电过电压的侵入还是很难达到抑制的,雷击直接或者间接到达监控系统的每个部位,直接可以导致该系统的损坏,从而经济和人员的财产安全方面都受到了严重的威胁。本文从监控系统的结构出发,最终通过分析雷击的主要途径,采取了一定的雷电防护措施。 With the continuous development of society, security monitoring is more and more widely used in society. Due to their special sensitivity, these monitoring equipments are still difficult to suppress the lightning overvoltage. The lightning strike directly or indirectly reaches every part of the monitoring system, which can directly cause the damage of the system, so that the economic and personnel Property safety has been a serious threat. In this paper, starting from the structure of the monitoring system, the lightning protection measures are taken by analyzing the main ways of lightning strikes.
