摘要
唐山 110 k V古冶变电站的地质结构 ,土壤电阻率从上到下逐渐增大可分为 3层 ,针对其具体地质和地形条件进行设计时将接地系统在水平方向适当外延 ,结合深井爆破和压灌低电阻率材料方法对该变电站接地系统进行施工。测量结果表明 ,该接地系统的实测接地电阻与设计值非常接近 ,做到了精确设计。随着计算机技术和数值分析技术的发展 。
The design and construction of 110kV Guye substation is implemented by explosion grounding technology. The geological structure of this substation can be divided into three layers according to the measured results. The grounding system include extensive horizontal grounding grid, and vertical grounding electrodes constructed by making cracks in the soil and filling low\|resistivity\|material into cracks. The measured grounding resistance of this substation after construction is close to its design value. With the development of computer and numerical analysis technologies, the design of grounding system should be changed from traditional simple design method to precise design by use of computer.
