摘要
通过对地网垂直接地极的敷设方式、数量等进行简要的理论分析和初步计算,并结合地网的降阻问题进行论述,得出通过改变短垂直接地极的参数来降低地网接地电阻值的效果是不明显的,对以后中小型地网接地电阻值的设计以及该项目的审核提供参考依据。
Combined with the question of the resistance reducing in earthing grid, the laying way and number of vertical earthing electrode in the earthing grid were theoretical analyzed and preliminary calculated. The results showed ： it was not very obvious for reducing the grounding resistance of grounding grid by changing the parameters of vertical earthing electrode. The paper provided references for the design and verification of the future grounding resistance for the middle and small earthing grid.
