【摘要】:為提高雷擊過電壓出現(xiàn)時(shí)智能建筑用電設(shè)備的安全性,本文根據(jù)行波理論確定了浪涌保護(hù)器的保護(hù)范圍,通過建立兩級浪涌保護(hù)器集中參數(shù)的π型電路等效分布參數(shù)電路模型,研究了保護(hù)級間的導(dǎo)通次序和配合機(jī)制,并分析了負(fù)荷大小和線路長度等因素對有效保護(hù)的影響,通過電磁暫態(tài)軟件ATP-EMTP進(jìn)行仿真,驗(yàn)證了結(jié)果的正確性,提出保護(hù)級間配合的最優(yōu)距離范圍.
[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.
