Abstract

a. L'invention concerne un dispositif de dérivation de surtensions à décharge dans un gaz (protecteur de surtension en gaz) comportant un boîtier rempli par un gaz, de préférence un gaz rare, et contenant pour la préionisation de sa charge gazeuse une substance radioactive, ledit boîtier contenant deux électrodes opposées et écartées par un corps isolant tubulaire et recouvertes au moins partiellement avec une masse les activant. b. La substance radioactive contenue dans du verre soluble est déposée sur une partie de la paroi intérieure du corps isolant 1, sur une ou plusieurs électrodes 2, 3 et/ou sous la forme d'une masse d'activation des électrodes ou sous la forme d'un constituant de celle-ci sur les électrodes 2, 3. c. Application à la protection d'appareils d'utilisation contre une surtension.at. The invention relates to a device for bypassing gas discharge overvoltages (gas surge protector) comprising a housing filled with a gas, preferably a rare gas, and containing a radioactive substance for the preionization of its gas charge. housing containing two opposing electrodes spaced apart by a tubular insulating body and covered at least partially with a mass activating them. b. The radioactive substance contained in water glass is deposited on a part of the inner wall of the insulating body 1, on one or more electrodes 2, 3 and / or in the form of an activation mass of the electrodes or in the form of a constituent thereof on the electrodes 2, 3. c. Application to the protection of user appliances against an overvoltage.
