GAS-FILLED DISCHARGER Russian patent published in 1994 - IPC

FIELD: gas-discharge engineering. SUBSTANCE: gas-filled discharger has dielectric casing 1 in the form of a sleeve hermetically connected to electrodes 2 and 3 located inside the sleeve. Electrode 2 uses core-type current lead 14, passed through a hole in bottom 5 of casing 1, and inactive end face tightened to the bottom internal surface, and electrode 3 uses flange 6 tightened to end face 7 of casing 1. The casing has annular bulges 8 and 9. Bulge 8 is at the end of the casing side wall, and bulge 9 - on the internal surface of the casing bottom. Gaskets 10 and 11 made of plastometering thermoplastic material are placed between the end faces of bulge 8 and flange 6, as well as of bulge 9 and electrode 2 facing each other. EFFECT: enhanced reliability due to increase of electric strength over the casing surface. 1 dwg
