FIELD: electricity. ^ SUBSTANCE: discharger comprises two metal electrodes with coaxial holes and a plate arranged between them and made of a hard dielectric, which a hole (a channel) coaxial with holes in electrodes, on an inner wall of which there is a groove. Arrangement of a solid dielectric material between electrodes and selection of geometric shape of electrodes and a dielectric ensure reduced intensity of an electric field near dielectric walls of a discharger channel, its enlargement in the channel centre, deflection of electric charges from discharger channel walls and distribution of discharge along an edge of holes in the cathode and anode. ^ EFFECT: production of a volume discharge in a discharger, which ensures switching time of 5 ns, reduced inductance and resistance of a discharge, reduced thermal and chemical effect of discharge plasma at structure parts, autonomous removal of ionised gas from an interelectrode gap and reduced dimensions of the discharger. ^ 1 dwg |
