建筑物防雷系统电气参数的计算

Calculation of the Electrical Parameters of Building Lightning Protection Systems

介绍建筑物避雷系统中钢结构体电气参数计算的 1种有效方法。它用平均电位法 ,计算钢筋分支导体的电容参数 ,用牛依曼公式计算其电感参数 ,对各钢筋分支间存在的电磁耦合 ,分别以参数的矩阵形式描述。将计算结果和实验结果进行了比较 ,两者能够较好地吻合 。

An efficient method is proposed in this paper to calculate the electrical parameters of conducting branches in the building lightning protection system. The capacitance matrix of conducting branches is determined in terms of the average potential method. Moreover the impedance(inductance) matrix of conducting branches is calculated by Neumaan' s formula. In order to check the validity of the proposed method, a comparison is made between calculated and experimental results. A better agreement in shown between them.
