  • Interrupting chamber of a circuit-breaker having two compression volumes
    Patent number: 8044318
    Abstract: A current interrupting chamber comprising a moving assembly movable axially between a start position and an end position of an operation of opening the circuit-breaker. The current interrupting chamber includes a first compression chamber; a hollow drive tube having ports for bringing the interior of the drive tube into communication with the outside of the current interrupting chamber; a second compression chamber; and a structure for obstructing the ports of the drive tube from the start position of an operation of opening the circuit-breaker and up to an intermediate position which is reached between the position of separation of two arcing contacts from each other and the end position of an operation of opening the circuit-breaker.

  • High-voltage or medium-voltage switch device with combined vacuum and gas breaking
    Patent number: 6849819
    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.
