智能建筑弱电系统的雷电防护设计

本文针对建筑物内弱电系统的特点,结合工程设计的实际,从直击雷防护、弱电系统雷电防护、共用接地系统、屏蔽、等电位连接、合理布线、电涌保护器的设计原则等方面入手,总结了电子设备针对雷电感应的各类防护措施,对"如何使建筑物内弱电设备的雷击损害降到最低程度"这个问题进行了深入探讨,其中重点论述了浪涌对弱电设备的危害及其预防措施。

Lightning Protection of Week Current System for Intelligent Buildings

In combination with the engineering design and contraposing the characteristic of the weak current system in buildings, the paper summarizes various types of protective measure against lightning for electric equipments, from the design principle of direct lightning, lightning-protection of weak current system, common earthing system, shielding, equipotential bonding, rational cabling and SPD. It discusses the problem of ＂how to reduce the lightning damage of the weak current equipments＂ and puts the emphasis on the imperilment and prevention of surge.
