Abstract: A gas-insulated high or medium voltage circuit breaker (100) comprising: a first arcing contact (101) and a second arcing contact (102), wherein at least one of the two arcing contact is axially movable along a switching axis (110), wherein during a breaking operation, an arc (120) between the first arcing contact (101) and the second arcing contact (102) is formed in a arcing region (125); a buffer housing (130) defining a pressurizing volume (140); a nozzle (150) arranged at a nozzle side (152) of the pressurizing volume (140), the nozzle (150) defining a channel (153) connected to the pressurizing volume (140) and directed to the arcing region (125), for blowing an arc extinguishing gas towards the arcing region (125) during the breaking operation, the nozzle (150) comprising a nozzle front face (160) facing towards the interior (180) of the pressurizing volume (140).

Abstract: An electric switching device (1) filled with a dielectric insulating medium comprises first and second arcing contact (3, 4), first exhaust volume (7) downstream of first arcing contact (3) and second exhaust volume (8) downstream of second arcing contact (4). The exhaust volumes (7, 8) comprise several first openings (14) in their walls (17), through which the insulating medium exits into third volume (9). The third volume (9) is arranged around the first or second exhaust volume (7, 8) and is radially delimited by the wall (17) of the exhaust volumes (7, 8) and by an exterior wall (11) having second openings (10) through which the insulating medium exits the third volume (9). One baffle device (2) is provided inside third volume (9) such that vortex flow of the insulating medium is generated when it passes the baffle device (2) on its way towards the second openings (10).

Abstract: An electric switching device filled with a dielectric insulating medium includes first and second arcing contact, first exhaust volume downstream of first arcing contact and second exhaust volume downstream of second arcing contact. The exhaust volumes includes several first openings in their walls, through which the insulating medium exits into third volume. The third volume is arranged around the first or second exhaust volume and is radially delimited by the wall of the exhaust volumes and by an exterior wall having second openings through which the insulating medium exits the third volume. One baffle device is provided inside third volume such that vortex flow of the insulating medium is generated when it passes the baffle device on its way towards the second openings. Turbulent flow conditions are chosen such that gravitational force allows to trap or contributes to trap particles in the baffle device. The baffle device comprises baffle plates or fins, that are arranged to form cavities for capturing the particles by gravitational force.
