建筑物弱电设备防雷设计

Lightning Protection Design of Weak Current Equipment in Buildings

针对建筑物和电子信息系统的雷电灾害防护现状,从雷电入侵的途径来划分建筑物防雷区域,介绍了电涌保护器和等电位联结在弱电设备防雷中的应用。指出弱电设备防雷设计时要合理地选择电涌保护器,使电子设备免受电涌过电压的破坏,实现有效地雷电电磁脉冲防护。

Aiming at the lightning protection status of building and the electronic information system, the lightning protection areas were divided from the lightning invasion way. The application of surge protective device （SPD） and the and equipotential bonding were introduced in the weak current equipment. It is pointed out that the SPD is reasonably selected to protect the electronic equipment from the destruction of the surge overvoltage and realize the effective protection of lightning electromagnetic pulse.
