Abstract

L'invention concerne un module coupe-circuit (100) pour courant continu (CC). Le module comprend un circuit(101) de courant continu (CC), un interrupteur sous vide commandé mécaniquement (104) destiné à interrompre le circuit de courant continu (CC), un actionneur à force de répulsion destiné à ouvrir l'interrupteur en réponse à la réception d'un signal de déclenchement (111), un circuit résonant actif (105) monté en parallèle avec l'interrupteur et un parafoudre (106) connecté en parallèle avec l'interrupteur. De préférence, l'actionneur est situé à l'intérieur de la chambre à vide de l'interrupteur. L'invention concerne en outre un coupe-circuit pour courant continu (CC), comprenant une pluralité de modules coupe-circuit montés en série. Par le montage en série d'une pluralité de modules coupe-circuit, il est possible de construire un coupe-circuit ayant une tension de fonctionnement voulue, qui est supérieure à la tension de fonctionnement d'un unique module coupe-circuit.
