Patent number: 10062526Abstract: Exemplary embodiments relate to a medium voltage switchgear with interlocking device associated with an actuator drive, which operates a switching element via a mechanical coupling element. The switching drive is movable in two end positions until which the interlocking is active between a freely selectable middle position and a specified end position. In order to keep the interlocking active over a certain range of the actuator travel, the mechanical coupling element includes a force flux element that is rotatable during operation of the drive from OFF to ON. In this way, the region where the interlocking shifts from unlocked to locked can freely be chosen by the shape of the force flux element.Type: GrantFiled: June 19, 2015Date of Patent: August 28, 2018Assignee: ABB Schweiz AGInventors: Christian Reuber, Philipp Masmeier

Patent number: 9478342Abstract: An actuator for a switchgear is disclosed, which can include a core having a package of core element layers made of magnetic material, and permanent magnets between the core elements, fixed with screws with screwheads. A movable plate is configured to open or close a magnetic circuit to the core, and an electromagnetic coil is surrounded by the core elements. To avoid mechanical infringement of the environment of the actuator by prominent screwheads, without weakening the magnetic force, screws for mechanical connection of the core element layers and the permanent magnets can be oriented perpendicular to the plane of stacking of the core element layers, and screw-holes for the screws can be implemented through the core element layers and the permanent magnets, and the screw-holes can end in diameter extended openings, so that the screwheads and/or the screwnuts are recessed into the diameter extended openings.Type: GrantFiled: November 18, 2014Date of Patent: October 25, 2016Assignee: ABB Schweiz AGInventor: Christian Reuber
