Abstract
The present disclosure provides a gas-insulated high or medium voltage circuit breaker including a first arcing contact and a second arcing contact, wherein at least one of the two arcing contacts is axially movable including a first and a second state of motion along a switching axis, wherein during a breaking operation, an arc between the first arcing contact and the second arcing contact is formed in an arcing region; a nozzle including a channel directed to the arcing region, for blowing an arc-extinguishing gas to the arcing region during the breaking operation; a diffuser adjacent to the nozzle, for transporting the gas from the arcing region to a region downstream of the diffuser; a buffer volume directly downstream of the diffuser, and an enclosure substantially surrounding the buffer volume circumferentially.
