To evaluate the protection performance of SPD (surge protective device) against electromagnetic pulse, the response ability of several typical surge protective devices to wide and narrow electromagnetic pulses was tested by using a SPD response ability test system. The results showed that SPD commonly used in lightning surge protection had certain ability to suppress electromagnetic pulse conduction disturbance. Gas discharge tubes presented typical clamping characteristics for wide pulses. MOV and TVS had obvious clamping effect on wide pulses, while had no clamping effect on narrow pulses, but could obviously reduce its peak value. Zener diodes had obvious clamping effect on narrow pulses, and the clamping voltage control accuracy was high.
为评估浪涌保护装置(SPD)对电磁脉冲的防护性能,利用SPD响应能力测试系统,测试了几种典型浪涌保护装置对宽、窄电磁脉冲的响应能力。结果表明,常用于雷电浪涌保护的SPD对电磁脉冲传导干扰具有一定的抑制能力。气体放电管对宽脉冲呈现典型的箝位特性。金属氧化物压敏电阻(MOV)和瞬态抑制二极管(TVS)对宽脉冲有明显的箝位效果,而对窄脉冲无箝位效果,但能明显降低其峰值。齐纳二极管对窄脉冲有明显的箝位效果,且箝位电压控制精度高。
