kU0bUd旧nwe一Cho跨步电位差(st印potential differenee)电流自接地电极经周围土壤流散时,会在土壤中产生压降并形成一定的地表电位分布,将地面上水平距为。.sm的两点间的电位差称为跨步电位差。 跨步电位差的最大值出现在电极附近的地面上和地网突出边角外侧的地面上。最大跨步电位差E.m和相应的电极(或地网)电位IR(I为经电极或地网流散的电流,R为电极或地网的接地电阻)的比值称为跨步电位差系数K.,即二,一箫 闭合均压地网的外缘各角应做成圆弧形,以使地网外侧地面的电位比较均匀,达到降低跨步电位差的目的,圆弧的半径可取均压带间距的一半。 均压带为等间距布置时,跨步电位差系数可按下图确定。
