  • Gas-blast circuit breaker with a radial flow opening
    Patent number: 8546716
    Abstract: A gas-blast circuit breaker is disclosed which includes a first contact and a second contact which can move relative to one another along a longitudinal axis. A blowout volume is arranged around the first contact. The blowout volume can be connected via a gas channel to an arc zone, in order to blow out an arc which is struck when the first contact is disconnected from the second contact. The blowout volume can be bounded radially on an outside by a separating element which separates the blowout volume from a low-pressure area. A flow opening, which allows a gas exchange, can lead in a radial direction from the low-pressure area into the blowout volume.
