Abstract

The invention relates to a disconnector switch for a high voltage direct current, HVDC, breaker, comprising a contact device (1) comprising a plurality of fixed contacts (6) arranged in a row defining at least one insulating gap (7) between each two fixed contacts (6) and a plurality of moving contacts (5) arranged in another row and each configured for electrically bridging a respective insulating gap (7) in a closed position, an actuating device (2) comprising an axially extending drive rod (8) fixing the plurality of moving contacts (5) and configured for axially moving the another row of the plurality of moving contacts (5) between an open position and the closed position, and an enclosure (3) comprising the contact device (1) and the actuating device (2) arranged therein and filled with a pressurized insulating gas, whereby a radially extending width (9) of at least one of the plurality of fixed contacts (6) is at least eight times greater than an axial gap extension (10) of the least one insulating gap (7).
