摘要
国家电力行业标准 DL/ T6 2 1- 1997《交流电气装置的接地》给出的方孔接地网的最大接触电位差计算公式 ,从原理上看 ,它只适用于计算正方形接地网的最大接触电位差。为此 ,用该公式作基本数学模型 ,以文献 [1]提出的等效矩形接地网的变换公式为依据 ,引入多变量的修正函数 ,并通过计算机数值模拟 。
Judging by its philosophy, the calculation formula for the max contact potential difference of grounding network with square holes, given in the national electric power industrial standard 《Earthing of AC Electrical Apparatus》DL/T621 1997,is only applicable to the calculation of max contact potential difference of square shaped grounding network Therefore, multivariable correction function is introduced, using this formula as a basic mathematical model and on the basis of the conversion formula of equivalent square grounding network put forward by Document [1],to induce the calculation formulas of max contact potential differencefor grounding network of arbitrary shape through computer numerical simulation
