摘要
研究了ENT800、R10K、QP160共3种铁氧体磁环在高空核电磁脉冲(high-altitude electromagnetic pulse,HEMP)传导防护中的应用性能,分析了磁环HEMP传导特性与磁环本身特性的关系。通过分析HEMP传导电流的能量谱与传导电流脉冲前沿的主要能量集中频段对应的磁环复相对磁导率,得出磁环相对磁导率对HEMP传导电流峰值的抑制规律以及相对磁导率的实部随HEMP传导电流脉冲前沿的变化规律。
Based on studying the properties of three ferrite magnetic rings like ENT800, R10K, and QP160 under high-altitude electromagnetic pulse （HEMP） conductive environ- ment, we analyzed the relationship between the HEMP conduction properties and the intrin- sic characteristics of magnetic rings. By analyzing the complex relative permeability of mag netic rings corresponding to the energy spectrum of HEMP conductive current and the main energy spectrum of the conductive current impulse front, we obtained the influence of the magnetic ring＇s complex relative permeability to the amplitude of the HEMP conductive current and the rise time of the HEMP conductive current.
