【摘要】 基于场路结合的思想,提供了一种分析地网性能的方法,用节点电压法分析接地网,考虑导体的自感、导体间的互感。暂态响应可以通过傅里叶变换而得到。此方法对任意层土壤下的接地网都适用,可容易地求出接地阻抗、最大跨步和接触电势系数,提供了实际应用的例子。更多还原

【Abstract】 Based on the field-circuit coupling theory, the paper analyses grounding grids performance by node method. This method takes into account the self-inducatance of conductors and mutual-inducatance among conductances. A transient response may be obtained by means of Fourier Transform. It can be used in layered soils. Grounding grids, maximal step and touch voltage coefficient can be computed easily. Practical applications are presented.更多还原
