摘　　要：针对1/4短路线对于雷电波能量的抑制性能,利用8/20μs实验平台,对不同频段下1/4波长SPD进行冲击测试,研究其对雷电波的抑制作用。研究表明:随着冲击电流的增大,1.8 GHZ和2.1 GHz频段下1/4波长SPD的电压值均呈先增大然后迅速变小的变化趋势;1.8 GHZ和2.1 GHz频段的插入损耗值均在-10 db以下,表明了传输线路中接入1/4波长短路线型SPD对信号传输不产生影响,可以确保通讯线路中信号的有效传输。In order to study the suppression performance of short-circuit line on the energy of lightning wave, the 8/20 p,s experimental platform is used to test the 1/4 wavelength SPD in different frequency bands, and the suppression effect on the lightning wave is studied. The results show that with the increase of impulse current, the voltage values of 1/4 wavelength SPD in 1.8 GHz and 2.1 GHz frequency bands are increasing first and then decreasing quickly. The insertion loss of the 1.8 GHz and 2.1 GHz frequency bands both below -10db, that means the transmission line access to 1/4 wavelength short-circuit type SPD does not affect the signal transmission, to ensure the effective transmission of signals in the communication line.
