摘要
无论建筑物还是电子设备,防直击雷均采用接闪带。事实上,接闪带并没有消除雷电流,而是将雷电流向下引导,在向下引导过程中会产生很强电磁场,对数量和功能不断增加的电子设备来说,增大了电子设备损坏几率。以接闪带为研究对象,以有限元分析法为理论基础,创建了实体模型,通过网络划分、施加载荷、计算与后处理等步骤,对接闪带接闪瞬间电位和电场进行了细致的有限元分析,为内部防雷即防感应雷做了必要准备,可以更好地保护由接闪带接闪瞬间所引起的电磁脉冲对人们生产生活带来的二次伤害。
Lightning strip does not eliminate lightning current, but guiding lightning current down,strong electromagnetic fields are generated during the downward guidance, the rapid development ofscience and technology, as for the increasing number and function of electronic equipment, such as ＂lead the wolf into the house＂ , increases the probability of electronic equipment damage. Take lightingstrip as the object of study, based on the finite element analysis method as the theoretical basis, theentity model is created, by mesh, apply load, calculation and postprocessing and the other steps, adetailed and meticulous finite element analysis of the electric potential and electric field at the instant oflightning strip lightning is made, for the internal lightning protection, that is, induced lightningprotection made the necessary preparation, it can better protect the secondary damage caused by the e-lectromagnetic pulse caused by the instant of the lightning strip lightning to the people＇s production andlife.
