    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.

    Abstract: The load break switch (1) comprises a housing (2) defining a housing volume for holding an insulation gas; a movable contact (20) and a fixed contact (10) arranged within the housing volume, the movable contact (20) being movable in relation to the fixed contact (10) along an arcuate trajectory (A) of movement and defining an arcing region (52) in which an arc is formed during an opening operation of the switch (1); a pressurizing system (40, 41), actuated by a movement of the movable contact (20) during opening of the switch (1), for pressurizing the insulation gas; a nozzle (30), the nozzle being arranged within the housing volume and being fixed to the movable contact (20) and/or defining a contacting part (20, 24) of the movable contact (20), wherein the nozzle (30) is adapted to blow the pressurized insulation gas into the arcing region (52) substantially tangentially to the arcuate trajectory (A).

    Abstract: Gas-insulated high voltage puffer breaker comprising a puffer unit with a movable piston running in a puffer cylinder and delimiting a puffer volume. A piston and a first contact member are attached to a piston stem. A piston and a first contact member are attached to a piston stem. An electric arc is extinguishable in an arcing zone when the first contact member moves from a first position to a second position. The puffer volume is fluidly connected to a gas nozzle by a gas channel such that the puffer volume comprises the gas channel as well as a portion of the puffer cylinder. The gas channel is provided radially outside of the puffer cylinder between a puffer cylinder wall delimiting the puffer cylinder and a wall structure of the puffer unit.
