GASOUS-DISCHARGE DEVICE WITH COLD CATHODE Russian patent published in 1997 - IPC

FIELD: electronics, gaseous-discharge devices with cold nonincandescent cathode called "pseudospark" commutators. SUBSTANCE: device comprises high-voltage electrodes - anode with or without hollow chamber and first cathode located in gas-tight and gas filled shell limited by metal walls with holes forming high-voltage discharge gap, auxiliary anode and second cathode located opposite to main anode part of device - control unit used to control moment of initiation of discharge and communicating with high-voltage gap through holes in electrodes and tank with reserve of working gas. First cathode is made near second cathode and auxiliary cathode is put inside second cathode made in the form of one or several closed spaces having one or several holes. Second cathode is made in the form of ring-like closed space which axis coincides with axis of device which has holes in face and internal cylindrical wall facing auxiliary anode. EFFECT: higher functional reliability and efficiency. 12 cl, 9 dwg
