避雷针安装高度及保护范围设计计算

On installation height of lightning rod and design calculation of protection scope

基于滚球法确定避雷针保护范围的基本方法,推导了单支独立避雷针和双支等高独立避雷针的安装高度和保护范围计算公式,算例表明,避雷针设计时,首先计算避雷针的安装高度和保护范围,然后再用作图法进行检验,这种设计过程符合一般的设计程序,为防雷设计提供了便利。

Based on the rolling sphere method, the paper indicates the basic methods for identifying the protection scope of the lighming rod, illustrates the installation height and the calculation formula of the protection scope of the single lightning rod and the double equal-height lightning rod, and proves by the calculation cases that the installation height and the protection scope of the lightning rod can be calculated in the first place, and what follows is to test with the mapping method, so the design process adheres to the general design procedure, and provides convenience for the lightning protection design.
