摘要
为解决现代城市建筑防雷问题,应用物理学的基础原理,对建筑防雷接地的概念进行批判。采用绝缘地基的中国古代建筑不仅经济,而且历千年不遭雷击;近年来众多现代建筑采用接地方式防雷,不仅耗资巨大,而且使室内信息设备频频招致雷灾。分析认为:在闪电过程中,似稳电路的概念和定律全失效了,应采用M axw e ll电磁场理论,阐明闪电的规律,接地的概念违反科学基本准则。事实证明:F rank lin避雷思维不适用于现代建筑防雷。“等离子避雷技术”是一种有效而经济的建筑防雷高新技术。
The use of grounding to protect structures against lightning is shown to he inconsistent with fundamental physical principles. Many information technology (IT) systems in building with grounded structures have been damaged by lightning strikes, while ancient Chinese structures without grounding have remained undamaged through thunderstorm for over a thousand years. The Franklin lightning protection theory is actually harmful for buildings with IT systems, especially the idea of the lightning protection grounds. Only Maxwell's electromagnetic theory can be used to design lightning protection systems, The results show that the plasma lightning protection technique is more effective.
