摘要
利用复合接地网接地电阻的三维单元网络模型,研究了几种接地网的接地电阻值。在消耗同样的工程用料情况下,比较了各种接地体的优劣,并对影响接地电阻大小的参数(如主框和侧边辐射线长度、接地网埋深、接地导体直径等因素)作了对比。计算结果可以用来指导接地网的设计。
By using a3-dimensional unit net model,the grounding resistances of different combined grounding systems are obtained.Under the condition of same consumption of ma-terial,the merits and the demerits of various grounding grids are compared.The influence factors of embedding depth,di-ameter of grounding conductors and the length of the main-frame on the grounding resistance are investigated deeply.
