Abstract (en)
The invention relates to a high voltage disconnector switch comprising a fixed first main contact (1) comprising at least one first contact element (4a), a fixed second main contact (2) comprising at least one second contact element (4b) and axially extending in extension of the fixed first main contact (1), a movable main contact (3) comprising an axially extending opening, arranged movably between an open position and a closed position and axially in parallel to the fixed first main contact (1) and the second main contact (2), whereby the movable main contact (3) is electrically connected in both positions via the at least one second contact element (4b) with the fixed second main contact (2) and only in the closed position via the at least one first contact element (4a) with the fixed first main contact (1), a fixed arcing contact (5) connected with a first end to the fixed first main contact (1), extending axially parallel to the movable main contact (3) and arranged for being encompassed on a second opposite end by the opening of the movable main contact (3), a movable arcing contact (6) movably arranged within the opening of the movable main contact (3), electrically connected via at least one third contact element (4c) to the movable main contact (3) and comprising a spring (8) arranged within the opening of the movable main contact (3) and configured for pushing, in the closed position, the movable arcing contact (6) onto and thereby electrically contacting the fixed arcing contact (5), and a power diode (7) arranged between the fixed first main contact (1) and the fixed arcing contact (5) and/or between the fixed arcing contact (5) and the movable arcing contact (6).
