Description
technical field [0001] The invention relates to the technical field of lightning protection, in particular to a lightning protection device. Background technique [0002] Lightning disaster is one of the ten most serious natural disasters announced internationally. Every year, lightning disasters occur frequently and involve a wide range of areas, posing a serious threat to the lives and property of the general public. Especially in today's rapid development of microelectronics technology, lightning discharge not only damages buildings and equipment at the lightning strike point, but also spreads rapidly in all directions due to the lightning strike energy traveling in the form of electromagnetic wave radiation and line transmission, which can make many nearby electronic equipment or power transmission Lines are destroyed at the same time, therefore, reducing lightning disasters is the primary goal of modern lightning protection technology. [0003] In related technologies...
