| 摘 要： | 本文提出了一种计算任意形状接地网接地电阻的新模型。它以电路的观点为基础,通过构建一个电阻网络来等效实际接地网,将接地网接地电阻的复杂计算转化为求解一个电阻网络的简单问题。用此方法计算了几种典型形状接地网的接地电阻通过与其他近似计算和数值计算结果进行比较,验证了本模型的正确性。

| Abstract: | A new model for computation on resistance to ground of arbitrary grid is put forward in this paper, which is named 3 -dimensional unit net model. This model is formulated on the viewpoint of network. By analyzing the current flowing process through the earth, a resistor network is used to represent the resistance to ground of a grid. By this model, the complicated computation of the resistance to ground of a grid becomes a simple problem to solve a resistor network. Some types of grids are simulated by this model, and the results are compared with other simulations. The utility of this model is demonstrated by comparing. |
