Abstract

a. Installation électrique asservie de commutation à haute tension. b. Installation caractérisée en ce qu'au moins l'une des électrodes principales, dans la zone du jaillissement d'étincelles, est constituée, pour plus de 90 % en poids, de préférence par un nitrure de l'un des métaux suivants : Al, Ce, Hf, La, Nb, Ta, Ti, V et Zr, ou bien par un mélange de nitrures de ces métaux avec une teneur en oxyde ou en oxynitrure correspondant à une teneur en oxygène de moins de 25 % en poids atomique du composé, la pression de gaz se situe de préférence entre 2 et 15 bars, une valeur de tension comprise entre 3 et 32 kV est prévue pour la tension d'allumage et la zone d'action de l'électrode de commande englobe au moins l'une des électrodes principales. c. L'invention s'applique notamment aux distributeurs d'allumage des moteurs à combustion interne.at. High voltage servo-controlled switching electrical installation. b. Installation characterized in that at least one of the main electrodes, in the area of the sparking, consists, for more than 90% by weight, preferably of a nitride of one of the following metals: Al, Ce, Hf, La, Nb, Ta, Ti, V and Zr, or else by a mixture of nitrides of these metals with an oxide or oxynitride content corresponding to an oxygen content of less than 25% by atomic weight of the compound , the gas pressure is preferably between 2 and 15 bars, a voltage value between 3 and 32 kV is provided for the ignition voltage and the zone of action of the control electrode includes at least the one of the main electrodes. vs. The invention applies in particular to the ignition distributors of internal combustion engines.
