摘　　要：现代的建筑物大多数采用钢筋混凝土结构,其防直击雷能力已经大大提高。但是在信息产业的飞速发展下,建筑物内部的微电子元件、电子设备、计算机设备越来越多,它们对雷电的耐受能力十分脆弱,导致雷击后造成的经济损失很大。通过对防雷接地系统中等电位连接、接地体、降阻三个方面的介绍、分析,提出自己的一些观点,供初学者参考。Most modern buildings use reinforced concrete structures,and their ability to prevent direct lightning has been greatly improved.However,with the rapid development of the information industry,there are more and more microelectronic components,electronic equipment and computer equipment inside buildings.They are very vulnerable to lightning,but the economic losses caused by lightning are very large.This article introduces and analyzes the three aspects of the equipotential bonding,grounding body,and resistance reduction of the lightning protection grounding system,and puts forward some views for the reference of beginners.

关 键 词：防雷 接地 等电位连接 接地体 降阻 低电阻率
