【摘要】 通过火箭引雷试验记录了避雷针和半导体消雷器两种防雷装置在雷电下接闪 (包括回击 )的图像、地面场强、回击次数及最大雷电流幅值数据 ,试验及分析表明 :避雷针对雷电闪络的通道有吸引作用但其保护角 <4 8°;消雷器的半导体长针在接闪过程中可自动并联放电和沿面闪络。更多还原

【Abstract】 The picture of lightning stroke and restroke, electric field on ground, restroke number and maximum current amplitude for lightning rod and semiconductor lightning eliminator are recorded by the rocket lightning attracting test. The protection effect of these two lightning protection devices are studied.更多还原
