摘要
根据恒定电流场理论,应用三维积分法将均匀土壤接地网的计算离散为以导体流散电流为变量的线性方程组,从而计算出从接地网流散出的总电流,进而计算接地电阻。该方法简单,但仅适用于均匀土壤模型。
Based on the theory of constant current field, a three-dimensional integral equation method is applied to scatter the caculation of grounding grids into a linear equation set, which used to obtain the dispersed current and the grounding resistance. The validity of the model is approved. The method is simple, but it is only applicable to u-niform soil.
