孔缝腔体对雷电波屏蔽效能的特性研究

Dianci bileiqi, 2017
针对雷电波通过传输线在不同孔缝屏蔽腔内对电子设备造成损坏等问题,通过对孔缝屏蔽腔体屏蔽效能的理论分析,并采用（impulse current generated system,ICGS）雷电冲击平台模拟8/20μs波形的雷电流,对不同孔径的屏蔽腔体进行试验分析。试验表明:金属屏蔽腔体对1.75 GHz雷电电磁信号的屏蔽效能与2.5 GHz的雷电电磁波相比,其屏蔽效果更好;当屏蔽腔体表面的孔缝直径为30 mm时,腔体对雷电电磁波的屏蔽效果最好,范围为16.5 dB18 dB ...

屏蔽体孔缝对雷电流屏蔽效能的影响

Dianci bileiqi, 2017
针对孔缝屏蔽腔内传输线上耦合雷电波的特性研究问题,对孔缝金属腔体屏蔽效能的理论分析,利用雷电试验冲击平台（ICGS）模拟产生雷电注入金属杆后模拟辐射雷电电磁波进行孔缝金属腔体屏蔽效能的实验。在孔缝数量一定时改变孔缝直径分析雷电电磁波进入金属腔体的特性。实验表明:金属腔体内部的天线接收到的电磁波信号基本上都是小于腔体外部的天线接收到的电磁波信号,即金属腔体对于雷电波产生的电磁波有屏蔽作用;改变孔径的大小,得出腔体的孔缝直径越小,雷电电磁信号对腔体的屏蔽效果越好范围为16.5dB-18dB之间 ...
