摘要
在发变电站中 ,通常铺设一层厚为 5～ 2 0cm的砾石或沥青混凝土 (以下简称砾石 )路面。给出了考虑这一高土壤电阻率路面层后 ,计算人体允许的接触电位差和跨步电位差的公式 。
The paper presents an accurate method to calculate tolerable touch and step voltage after taking into account the gravel layer which is popular in substation yard.The errors of current evaluate method are discussed in detail.
