随着交通事业和电子科技的发展,监控设备被广泛地应用于高速公路中,但由于高速公路监控系统的电磁兼容能力低下,抗雷电电磁脉冲过电压的能力十分脆弱,在闪电环境下易损性较高,雷击伤害已成为高速公路监控系统的一大危害,引起了高速公路运维企业的普遍关注。本文通过对雷电危害的讨论,结合高速公路机电系统监控设备的实际情况,分析了防雷接地技术,并提出了有效的防雷措施。
With the development of transportation and electronic technology, monitoring equipment is widely used in expressways. However, due to the low electromagnetic compatibility of expressway monitoring and control systems, the capability of anti-lightning electromagnetic pulse overvoltage is very fragile and vulnerable in the lightning environment Higher sex, lightning damage has become a major hazard monitoring system of the highway, causing the highway operation and maintenance of the general concern. Based on the discussion of the lightning hazard and the actual situation of the monitoring equipment of the highway electromechanical system, this paper analyzes the lightning protection grounding technology and puts forward the effective lightning protection measures.
