| 摘 要： | 输电线路杆塔接地设计中,通常应用经验公式计算杆塔接地电阻,计算精度有限.为此,考虑到接地导体扩散电流的不均匀性,对接地导体进行分段处理,计算各分段导体的自电阻系数和互电阻系数,进而求得接地导体的接地电阻.可根据精度要求确定分段数量,分段数量越多,计算精度越高.最后分析了输电线路杆塔常用的射线接地体、双环形接地体分别在不...

| Abstract: | In the grounding design of high voltage transmission line the empirical formula is often used to calculate the grounding resistance of transmission tower,so the calculation accuracy is just passable.Considering the non-uniformity of the current dispersed from the grounding electrode,a grounding electrode is divided into sections to calculate their self-resistance coefficients and mutual resistance coefficients,thus the grounding resistance of grounding electrode is solved.The number of conductor sections is... |
