摘要： A switch-fuse module and a ring main unit. The switch-fuse module includes: at least one fuse; and at least one fuse canister having the fuse inside; the security device including: at least one slider configured to linearly move between an open slider position and a closed slider position; at least one earthing switch that i) is galvanically connected to an end of the fuse, ii) is operable between an open and a closed state, iii) is designed to earth the end of the fuse in the closed state, and iv) is coupled to the slider in such a manner that the open slider position effects the open state of the earthing switch and the closed slider position effects the closed state of the earthing switch; an energy-storing propulsion element configured to move the earthing switch from the open to the closed state when discharging; and a locking mechanism adapted for blocking access to the fuse in a locked state and for releasing access to the fuse in an unlocked state, wherein the slider is coupled to the locking mechanism in such a manner that the slider is in the closed slider position while the locking mechanism is in the unlocked state, so that the fuse may only be accessed if it is ensured that the fuse is earthed.

摘要： A load-break switch has a housing holding insulation gas at ambient pressure; a first main contact and a second main contact being movable relative to each other in an axial direction of the switch; a first arcing contact and a second arcing contact being movable relative to each other in the axial direction and defining an arcing region where an arc is formed during a current breaking operation, wherein the arcing region is located radially inward from the first main contact; a pressurizing system pressurizing a quenching gas during the current breaking operation; and a nozzle system arranged to blow the pressurized quenching gas onto the arc. The first main contact includes at least one pressure release opening to allow gas flow in a radial outward direction. A total area of the pressure release opening suppresses a reduction of gas flow out of the pressure release opening.
