视频监控系统的雷电防护研究

如今计算机和自动控制系统的成熟运用和大范围推广,更加高效全面的监控系统在各行各业当中得到广泛运用。因为监控系统拥有低电压、微电流的特点,同时自身的抗干扰能力较弱,并且每套监控系统所覆盖和包含的范围与场景较为复杂,因此走线和布线通常都是非常凌乱,这就导致监控系统设备遭受雷击的可能性大幅增加。视频监控系统是安全体系构建当中的重要组成部分,为确保能够平稳运行,做到正确雷电防护是十分重要的。该文针对视频监控系统雷电入侵渠道及生成原因进行深入分析,并以实际案例为切入点简单介绍电涌保护器的性能参数、线缆屏蔽、系统接地等电位连接的现代化防雷理念。

Nowadays,with the mature application and large-scale promotion of computers and automatic control systems,more efficient and comprehensive monitoring systems have been widely used in a variety of industries.Because the monitoring system has the characteristics of low voltage and micro-current,and its own anti-interference ability is weak,and the scope and scene covered by each monitoring system is more complex,the wiring and wiring are usually very messy.This leads to a great increase in the possibility of lightning strikes on the monitoring system equipment.Video surveillance system is an important part of the construction of security system,in order to ensure smooth operation,so it is very important to achieve correct lightning protection.This paper makes an in-depth analysis of the lightning intrusion channel and the generation reasons of the video surveillance system,and briefly introduces the concept of modern lightning protection in potential connection,such as the performance parameters,cable shielding,system grounding of surge protector.
