高速公路系统中电子设备的雷电过电压保护

Lightning Surge Protection for Expressway Electronic Equipment

目前 ,尚无有关于以电磁兼容原理将不同的过电压保护器用于高速公路系统的标准规范 ,解决这一问题需要引入一个雷电保护区的概念。高速公路的监控、收费和通信 3个系统的雷电保护区按照需保护的区域不同 ,将高速公路的 3个系统划为几个保护区域 ,并按电磁兼容的要求确定过电压保护器的安装位置。

At present there is no standard specification for electromagnetic compatibility based over-voltage protection system used for expressway. To deal with this issue, it is necessary to introduce a concept of lightning protection area. The lightning protection area for the traffic surveillance and control system, toll collection system and communication system for the expressway shall be different in terms of different needs of the three systems, and it is necessary to define the location of the over - voltage protection system based on the requirement of electromagnetic compatibility.
