Abstract

L'invention a trait au domaine des éclateurs pour surtensions électriques. L'éclateur selon l'invention comprend deux électrodes 6 et 7 dont un tronçon de chacune est recouvert d'un revêtement isolant 16. Ces électrodes sont disposées dans une enceinte et la tension continue d'amorçage de l'intervalle séparant les électrodes de l'élément central 3 de l'enceinte est inférieure à la tension de rupture dans tout intervalle compris entre un point des électrodes et un revêtement conducteur formé par pulvérisation de matière sur la surface intérieure des tronçons isolants 4 et 5 de l'enceinte. Domaine d'application : éclateurs électriques.
