无线通信车的防雷技术

针对机动通信防雷的应用需求,以无线通信车为例,对无线通信车载设备遭雷击破坏的原因进行了分析,对空中防雷基本原理进行描述。提出以LPI主动式防雷器、专用引下线和泄流地网组成防雷设备,利用防雷设备LPI主动式引雷器的电极提前放电,使得空中下行雷电轨迹发生变化,将上行电极和下行电极在空中相遇,主动引入防雷器,经专用引下线(低阻抗的软铜带线)接入泄流地网,从而达到防雷保护的要求,从工程应用上提供了具体的实现途径及方法。

Lightning protection technology for radio communication vehicle

This article takes radio communication vehicle as an example,in view of the demand of lightning protection in mobile communication,analyzes the destruction reason of radio communication vehicular equipments by lightning,describes the basic principle of lightning protection in air,puts forward the lightning protection equipment composed by using LPI active form lightning protection unit,special down-lead and the effusion ground network.It uses discharging of the LPI electrode ahead of time,changes the lightning track,so the lightning will take place between two electrodes,the lightning protection equipment will effuse the lightning current via down-lead(low impedance soft-copper stripline) to ground network.In this way,the lightning protection is functioned.This paper has provided the realization way from the project application.
