摘要
阐述了避雷针的引雷原理。指出避雷针良好的避雷效果除了与其自身的性能有关,还与避雷针的保护范围、高层建筑物高度、接地电阻等有关。计算结果表明,雷电流在避雷针处泄放,可对保护范围内保护对象起到保护作用,避免了在避雷针附近其他物体发生闪络。
The leading thunder principle of lightning rod were elaborated.It was pointed out that the good lightning protection effect of lightning rod depended on the performance and protection range of the lightning rod,height of high-rise building,and the grounding resistance.The calculation results show that the lightning current is discharged at the lightning protection,which protects the objects within the scope of protection,to avoid the flashover of other objects near the lightning rod.
