| 雷电侵害网络设备的几种途径 Lightning infringes several ways of network equipment 雷电侵害计算机网络有两种方式：直击雷侵害和感应雷侵害.雷电直接击中设备所在建筑物或设备连接线路并经过网络设备入地的雷击过电流称为直击雷;由雷电电流产生的强大电磁场经导体感应出的过电压，过电流所形成的雷击称为感应雷.直击雷击中建筑物，会产生强大的雷电流，如果电压分布不均会产生局部高电位，对周围电子设备形成高电位反击，击毁建筑物，损坏设备，甚至造成人员伤亡.感应雷一般由电磁感应产生，通过电力线路，信号馈线感应雷电压入侵计算机网络系统，从而造成网络系统设备的大面积损坏.因而雷电对计算机网系统的入侵主要有三个途径。 Lightning violations of the computer network has two ways: direct lightning and induction lightning. Thunder and lightning hit directly equipment in buildings, or equipment through the network connection lines and equipment into the lightning current is called direct lightning; Strong electromagnetic fields produced by lightning current through the conductor induced over-voltage, over current of lightning is called induction lightning. Hit by lightning in buildings, produce powerful lightning current, if the voltage distribution can produce local high potential, on the surrounding electronic equipment to form high potential, destroy buildings, damage to equipment, and even cause casualties. Induction lightning usually generated by electromagnetic induction, through the power line, signal feeder induction lightning invasion of computer network system voltage, thus cause massive damage. In the network system equipment and the invasion of the computer network system of the thunder and lightning there are three main ways. |
