《中国消防》1987年第4期中刊登的黄士荣同志《感应雷击与防雷》一文,详述了感应雷击的原理及其预防措施,读后深受教益。但对文中“一般避雷装置(避雷针、避雷带、避雷网等)是不能防止感应雷击的”观点不太理解,觉得还应对具体情况作具体分析。一、笼式避雷网能够预防感应雷击。笼式避雷网防雷的主要依据是利用古典电学中的法拉第笼原理。对雷电来说,它起到两种作用:一是均压作用,二是屏蔽作
The article entitled “Induction Lightning and Lightning Protection” by Huang Shirong published in “China Fire Protection” No. 4, 1987, described in detail the principle of induction lightning stroke and its preventive measures, and was widely learned after reading. However, the article “General lightning protection devices (lightning rods, lightning protection, lightning protection network, etc.) can not prevent the induction of lightning” point of view do not quite understand, I think we should also make specific analysis of the specific circumstances. First, the cage lightning network to prevent induced lightning. Cage lightning protection network lightning is the main basis for the use of classical Faraday cage principle. For lightning, it plays two roles: one is equalizing, and the other is shielding
