ABSTRACT:
A hybrid high-voltage or medium-voltage breaker device includes an enclosure filled with a dielectric gas, a vacuum switch, a gas switch and an operating rod. The vacuum switch includes a fixed first arc contact and a second arc contact which can move in translation in an axial direction of the enclosure. The gas switch includes a fixed or quasi-fixed third arc contact and a fourth arc contact which can move in translation. The operating rod is connected to the fourth contact. The device also includes a connection arrangement for electrically connecting the second and third contacts and a displacement arrangement connected to the connection arrangement and to the rod which separates the second and fourth contacts from the first and third contacts, respectively.
