| 摘 要： | 探讨雷电电涌对计算机系统的危害,提出了对电源系统电涌保护器SPD(限压型SPD、开关型SPD、复合型SPD)的选择,及信号系统电涌保护器(双绞线通信线路SPD、网络数据线路SPD、高频天馈线SPD)的选择。应综合考虑被保护对象的地理环境,根据保护对象的气象条件作合理的雷电风险分析,实行计算机系统的SPD多级保护。

| Abstract: | This article discusses the damage of computer system due to lightning surge,and introduces the choice of surge protective device SPD(voltage limiting type SPD,switching type SPD,combination type SPD)for power system as well as signal system surge protective device(twisted-pair communicating circuitry SPD,network data circuitry SPD,high frequency air feedback circuitry SPD). Considering the geographical situation and reasonably analyzing the lightning strike risk according to the weather conditions of the protective target,multi-level SPD protection may be adopted for computer system. |
