摘要： The present disclosure provides a gas-insulated high or medium voltage circuit breaker (100) including a first arcing contact (101) and a second arcing contact (103), 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 (140), 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 (110) including a channel (112) 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 (170) directly downstream of the diffuser, and an enclosure (120) substantially surrounding the buffer volume (170) circumferentially, wherein the enclosure includes an inner enclosure portion (123) and a coaxially arranged outer enclosure portion (121), wherein at least one of the inner portion and the outer portion is movable relative to the other one; and a first aperture (127) provided on a surface of the inner enclosure portion and a second aperture (125) provided on a surface of the outer enclosure portion, such that a through opening is providable through the enclosure (120), wherein in the first state of motion during a breaking operation the through opening is blocked, as to prevent the gas from being released from the buffer volume (170) to a volume outside (180) of the enclosure (120); and in the second state of motion, the first aperture (127) and the second aperture (125) overlap, such that the overlap of the first aperture and the second aperture provides the through opening for the gas to be partially released from the buffer volume (170) to the volume outside (180) of the enclosure.

摘要： A gas-insulated high-voltage switching device (1) is provided, which includes an arcing contact arrangement (5) having a first arcing zone member (30) and a second arcing zone member (20) that are movable relative to one another along an axis (B). An auxiliary nozzle (40) surrounds at least a part of a second arcing contact unit (21) and has an auxiliary nozzle throat (42) having an axial extension and allowing passage at least of an end of the first arcing contact unit (31). A main nozzle throat (52) has an axial extension sideways of the auxiliary nozzle throat (42) and allows passage at least of the end of the first arcing contact unit (31). A cross-sectional area of the main nozzle throat (52) is substantially decreasing in the direction away from the auxiliary nozzle throat (42) so as to form a substantially converging duct for the flow of an arc-extinguishing gas.
