Abstract

L'invention concerne un ensemble de commutation (20, 40) pourvu d'un relais électromagnétique (21, 41) qui comporte une bobine de relais (21a, 41a) et des contacts de commutation (21c, 41c), d'une source de tension (43) reliée à la bobine de relais (21a, 41a) et d'un circuit de commande (23, 44) conçu pour commander la bobine de relais (21a, 41a) au moyen d'une tension fournie par la source de tension (43). L'invention vise à configurer un tel dispositif de commutation (20, 40) de telle manière que, pour une structure simple, le temps de commutation puisse être rendu le plus court possible. A cet effet, le circuit de commande (23, 44) est conçu pour appliquer à la bobine de relais (21a, 41a), pour l'excitation du relais (21, 41), une tension d'excitation élevée, supérieure à la tension nominale du relais (21, 41) et, pendant le processus d'excitation du relais (21, 41), au lieu de la tension d'excitation, une tension normale inférieure à la tension d'excitation et fournie par la source de tension (43). Un courant de bobine s'écoulant à travers la bobine du relais (21a, 41a) est utilisé pour la détermination d'un instant de commutation auquel s'effectue la commutation à la tension normale. L'invention concerne également un procédé correspondant pour la commande d'un relais (21, 41).
