| 摘 要： | 由于设置在建筑物天面或者建筑物附近的独立接闪杆在引雷入地过程中将产生瞬态高电位,电磁感应经传导、耦合可能致损电气或电子设备,造成跨步电压可能危害路经行人。根据电磁场理论、借鉴建筑物引下线分流技术等,给出跨步电压的计算公式和安全门限、为了降低独立接闪杆负面效应,提出了在独立接闪杆空心钢管内使用多股阻燃铜缆的多路分流技术,并在文物防雷工程中实施应用。

| Abstract: | Independent lightning rods on building roofs or nearby areas will produce transient high potential, which may damage electric and electronic equipment through electromagnetic induction and couple, and step voltage may harm pedestrians. Based on electromagnetic theory, by means of the building down lead current splitting technique, the calculation formula and security thresholds of step voltage are given. In order to relieve the adverse effects of independent lightning rods, the current splitting technique, in which the multi channel several anti fire copper lines are used in the hollow steel pipes of the lightning rods, is proposed, and it has been applied in the lightning protection of cultural relics. |
