【摘要】：为提高雷击过电压出现时智能建筑用电设备的安全性,本文根据行波理论确定了浪涌保护器的保护范围,通过建立两级浪涌保护器集中参数的π型电路等效分布参数电路模型,研究了保护级间的导通次序和配合机制,并分析了负荷大小和线路长度等因素对有效保护的影响,通过电磁暂态软件ATP-EMTP进行仿真,验证了结果的正确性,提出保护级间配合的最优距离范围.
[Abstract]:In order to improve the safety of electrical equipment for intelligent building when lightning overvoltage occurs, the protection range of surge protector is determined according to the traveling wave theory, and the equivalent distribution parameter circuit model of 蟺 type circuit with concentrated parameters of two-stage surge protector is established. The conduction sequence and coordination mechanism between protection stages are studied, and the influence of load size and line length on the effective protection is analyzed. The simulation results of electromagnetic transient software ATP-EMTP are used to verify the correctness of the results. The optimal distance range of cooperation between protection levels is proposed.
