Abstract: An interrupter unit (1) for gas blast circuit breakers has a central axis A and comprises a first contact portion (10) with arcing contact (12), a second contact portion (20) comprising a cylinder shaft (22) and a pin contact (25), an insulating nozzle (30) fixed to the first contact portion (10) and having a first section (32) surrounding the arcing contact (12), an intermediate cylindrical section (34) and a divergent section (36). A heating channel (40) with circumferential opening (42) leading into the nozzle (30) guides compressed gas into an arcing zone (50) during opening operation of the interrupter unit (1). At the circumferential opening (42) of the heating channel (40), a circumferential edge region (46) between a first side wall (60) of the heating channel (40) and a wall of the cylindrical nozzle section (34) comprises at least one edge (47) with an enveloping radius of at most 2 mm.

Abstract: 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.
