Formula of going forward one by one is discharge device step by step

The utility model discloses a formula of going forward one by one is discharge device step by step. Formula of going forward one by one is discharge device step by step is during with supporting use of lightning -proof insulator or lightning -proof insulator strain clamp cluster of taking discharge gap, can go out power frequency arc, the protection circuit that the thunder and lightning causes fast and not receive the thunderbolt to damage, stop or reduce thunderbolt tripping operation number of times when receiving the thunderbolt. The storehouse of discharging that formula of going forwardone by one is discharge device step by step comprises a solid insulating material, two metal central electrodes, N (N >= 2) individual metal transition electrode constitution. The transition electrodeis in discharge and arrange along the inner wall in the storehouse. Any two adjacent the interval of electrode (including central electrode and transition electrode) is not more than all the time anyone electrode is to removi
