摘要
本文分析了导体间距从地网边缘到中心逐渐增加的布置方式,不等间距接地网的优越性;给出了不等间距接地网均压导体的布置规律。按此规律布置的不等间距接地网,网孔电位波动值不超过2%,并能节约地网耗费30%以上。
This paper analyses the superiority of arranging voltage-sharing conductors with une- qual spacing that increases from the edge to the centre of a grounding grid.and the law for arranging conductors with unequal spacing is presented.When the grounding grids are arranged by this law,the relative differences among mesh Potentials are less than 2 percent,and more than 30 Percent of grid expend can be saved.
