Abstract: The disclosure relates to a gas-insulated load break switch (1) and a gas-insulated switchgear (100) comprising a gas-insulated load break switch (1).
The gas-insulated load-break switch (1) has a housing (2) defining a housing volume for holding an insulation gas at an ambient pressure; a first main contact (80) and a second main contact (90), the first and second main contacts (80, 90) being movable in relation to each other in the axial direction (A) of the load break switch (1); a first arcing contact (10) and a second arcing contact (20), the first and second arcing contacts (10, 20) being movable in relation to each other in an axial direction (A) of the load break switch (1) and defining an arcing region in which an arc is formed during a current breaking operation, wherein the arcing region is located, at least partially, radially inward from the first main contact; a pressurizing system (40) having a pressurizing chamber (42) for pressurizing a quenching gas during the current breaking operation; and a nozzle system (30) arranged and configured to blow the pressurized quenching gas onto the arc formed in the quenching region during the current breaking operation, the nozzle system (30) having a nozzle supply channel for supplying at least one nozzle (33) with the pressurized quenching gas.
The first main contact (80) comprises at least one pressure release opening (85) formed such as to allow a flow of gas substantially in a radial outward direction, wherein the total area of the at least one pressure release opening (85) is configured such that during a supply of the pressurized quenching gas, a reduction of the flow of gas out of the pressure release opening (85) is suppressed.

Abstract: A gas-insulated low- or medium-voltage load break switch (1) comprises: a housing (2) defining a housing volume for holding an insulation gas at an ambient pressure; a first arcing contact (10) and a second arcing contact (20) arranged within the housing volume, the first and second arcing contacts (10, 20) being movable in relation to each other along an axis (12) of the load break switch (1) and defining a quenching region (52) in which an arc (50) is formed during a current breaking operation; a pressurizing system (40) having a pressurizing chamber (42) arranged within the housing volume for pressurizing a quenching gas from an ambient pressure p 0 to a quenching pressure p quench during the current breaking operation; and a nozzle system (30) arranged within the housing volume for blowing the pressurized quenching gas in a subsonic flow pattern from the pressurization chamber (42) onto the arc (50) formed in the quenching region (52) during the current breaking operation. The nozzle system (30) comprises at least one nozzle (33) arranged for blowing the quenching gas from an off-axis position predominantly radially inwardly onto the quenching region (52).

Abstract: The present invention relates to a device for interrupting non-short circuit currents only, and in particular relates to a disconnector, more particularly high voltage disconnector, or to an earthing switch, more particularly make-proof earthing switch, and further relates to a low voltage circuit breaker. The device comprises at least two contacts movable in relation to each other between a closed state and an open state and defining an arcing region, in which an arc is generated during a current interrupting operation and in which an arc-quenching medium comprising an organofluorine compound is present. According to the application, a counter-arcing component is allocated to the arcing region, the counter-arcing component being designed for counteracting the generation of an arc and/or being designed for supporting the extinction of an arc.
