  • Gas blast interrupter
    Patent number: 9035211
    Abstract: A gas-insulated circuit interrupter is disclosed, the interrupter having an improved design for quenching electrical arcs. The interrupter includes a first contact and a second contact configured to alternatively connect to and disconnect from the first contact. One or both of the contacts are at least partially contained in an arcing chamber. The arcing chamber includes the point at which the contacts connect during current-carrying operation of the interrupter. The arcing chamber is at least partially surrounded by a heating chamber for accommodating a quenching gas. A channel connects the heating chamber and the arcing chamber and is positioned to direct the quenching gas toward the first contact and the second contact arcing area. One or more valves direct gas from the arcing chamber to the heating chamber when the interrupter is operated to interrupt a current.
