西北干旱土壤环境对接地技术影响的研究

Study of the influences of arid soil conditions on earthing technology in Northwest China

为了研究西北干旱土壤对防雷接地技术的影响,在宁夏境内选择2种不同的土壤环境,分别设置了3种不同结构的防雷接地体.经过1 a的对比观测,分析了平均气温和土壤湿度2个因素的变化对不同土壤电阻率和不同结构接地电阻的影响,说明了不同土质结构在不同时间(或季节)内、不同的温湿度条件下,不同结构防雷接地体的变化特点和影响规律,提出了防雷接地体的敷设和结构性能最优要求.

By two different soil conditions selected and three types laying of lightning grounding body setup for each in the arid area of northwest of Ningxia, and according to one year＇s observation comparison and regression analysis, the influence of average temperature and soil humidity on soil resistivity and earthing resistances with different structures is used to show the variation characteristics and changing regulation about the objects of grounding for lighting under the different soll conditions of various time （seasons）, humidity and different structures. Furthermore, optimization of structure and performance and laying of lightning grounding body were put forward.
