Abstract
A hybrid interrupter device includes a casing filled with a dielectric gas; a vacuum interrupter having a first arcing contact which is fixed and a second arcing contact which moves in translation in the axial direction of the casing; a force exertion device for exerting a force on the second contact while the vacuum interrupter is allowing current to pass; a gas interrupter having a third arcing contact which is fixed and a fourth arcing contact which moves in translation; and a drive rod connected to the fourth contact. The device further includes a connection device electrically interconnecting the second and third contacts, and capable of being moved in translation together with the second contact; and a displacement mechanism connected to the connection device and to the rod for displacing them so as to separate the second and fourth contacts from the first and third contacts, respectively.
