摘　　要：常规电涌保护器(SPD)的后备保护装置存在严重的保护盲区。通过研究雷电流和工频电流的幅度频率的特性,采用两条平行通路的方式对各种电流实现选择性通过和分断,并将其有机整合,应用到产品中。The conventional surge protection device(SPD)backup protection device has the serious protection blind area.Through the study of lightning current and power frequency current amplitude frequency characteristics,two parallel channels are used to selectively pass and cut off various currents,which are organically integrated and applied to products.

关 键 词：电涌保护器 后备保护装置 雷电流 工频电流
