Abstract

a. Dispositif de protection pour protéger contre des tensions anormales. b. Il comprend une gaine métallique cylindrique de mise à la terre; une électrode ou substrat conducteur disposé dans la direction axiale de la gaine métallique; un tube isolant de forme évasée qui est disposé entre la gaine métallique et l'électrode ou le substrat conducteur; et plusieurs résistances non-linéaires disposées dans le tube isolant, les résistances non-linéaires étant connectées respectivement pour que la distribution de potentiel de ces résistances soit sensiblement similaire à la distribution de potentiel de ladite gaine métallique. c. Application pour parafoudre.
