高层建筑中降低共用接地电阻值的方法

Method in reducing the shared grounding resistance value in the tall building

建筑防雷工程是一个系统工程,在高层建筑的实际施工中从基础开始,如何降低接地装置的接地电阻就显得十分重要。从高层建筑物的特点出发,介绍实际施工中的两例既经济又简便的方法,一般共用接地电阻值都小于1Ω,对于降低高层建筑中共用接地电阻值具有很好的效果。

Building the lightning protection project is a systematic engineering. It is very importantto reduce the grounding resistance of the grounding device from the foundation in the actual construction of the high-rise building. Based on the characteristics of high-rise buildings, the paper introduces two economical and simple methods. Generally the shared grounding resistance values should be less than 1 Ohm , and they are very good for lowering the highrise building shared grounding resistance values.
