摘　　要：提出了一种可以明显降低接地电阻的新型接地装置,文章从理论上分析了该接地装置的降阻机理及其在复合地网中的降阻效果,给出了应用该新型接地装置的工程设计方法和计算公式,并通过模拟试验和实际工程应用验证了理论分析所得的结论。模拟试验和工程应用结果均表明,新型接地装置在土壤电阻率较高或地网占地面积较小的接地工程中,具有散流特性好、降阻效果好等优点,能较好地适用于高土壤电阻率和占地面积较小的接地工程。A new type of grounding device, by which the grounding resistance can be considerably reduced is presented. Here, the mechanism of resistance reduction of this device and its resistance reduction effect in a compound grounding mesh are theoretically analyzed, the engineering design of this device and corresponding calculation formulae are given. The results from simulation and engineering applications of this device show that for the construction sites with higher soil resistivity or smaller area for grounidng mesh, the presented grounding device is good in current diffusion and resistance reduction, so it is suitable to the grounding grid in high resistivity zones or the grounding grid with scanty area.
