Patent number: 11887793Abstract: A three-position disconnector switch includes a platform, a power in contact, a power out contact, an earthing contact, and a piston. In a first position, the piston contacts the power out contact and the power in contact. In a second position, the piston contacts the power out contact. In a third position, the piston contacts the power out contact and the earthing contact. The piston moves along an axis to transition between the different switch positions. The power in contact is mounted to the platform, the power out contact is mounted to the platform, and the earthing contact is mounted to the platform.Type: GrantFiled: May 13, 2022Date of Patent: January 30, 2024Assignee: ABB Schweiz AGInventors: Michal Skuci, Josef Cernohous, Radek Javora, Tomas Kozel, Dietmar Gentsch

Patent number: 11795729Abstract: A handle for a compartment of a low, medium or high voltage switchgear includes: a body part; a hand grasping part; and a lock. The handle is movable from a closed position to an open position. When the handle is in the closed position, the handle is not useable to open a door of a compartment of the switchgear. When the handle is in the open position, the handle is useable to open the door of the compartment of the switchgear. In the open position, the hand grasping part is positioned so as to be graspable by a human user. In the closed position, a transition of an active element in the compartment of the switchgear from a quiescent state to an active or potentially active state activates the lock. Activation of the lock stops the handle from moving from the closed position to the open position.Type: GrantFiled: July 29, 2021Date of Patent: October 24, 2023Assignee: ABB Schweiz AGInventors: Michal Skuci, Josef Cernohous

Patent number: 11791109Abstract: A three-position disconnector switch includes an earthing contact, a power out contact, a power in contact, and a piston. The power out contact comprises first and second parts connected by a leg portion. In a first position, the piston contacts the first part of the power out contact. In a second position, the piston contacts the first part of the power out contact and makes electrical contact with the second part. In a third position, the piston contacts the second part and makes electrical contact with the earthing contact. The piston is configured to move along an axis of the three-position disconnector switch to transition the three-position disconnector switch between the different switch positions.Type: GrantFiled: May 11, 2022Date of Patent: October 17, 2023Assignee: ABB Schweiz AGInventors: Michal Skuci, Josef Cernohous, Radek Javora, Tomas Kozel

Patent number: 11688569Abstract: A switch includes a power in contact, a piston, a power out contact, a plurality of flexible locking elements, an earthing contact, and a threaded rod. In a first position, the piston contacts the power in contact and the power out contact. In a second position, the piston contacts the power out contact. In a third position, the piston contacts the earthing contact and the power out contact. The piston comprises an inner threaded section that engages the threaded rod. Rotation of the threaded rod moves the piston along an axis of the switch between the different switch positions. The piston comprises a groove extending in a direction parallel to the axis. Each of the flexible locking elements is configured such that a part of each of the flexible locking elements moves into and out of the groove as the piston is moved along the axis of the switch.Type: GrantFiled: May 10, 2022Date of Patent: June 27, 2023Assignee: ABB Schweiz AGInventors: Michal Skuci, Josef Cernohous, Radek Javora, Tomas Kozel

Publication number: 20230029540Abstract: A medium voltage switchgear or control gear includes at least one first compartment; a cable compartment; a plurality of main components; and a plurality of auxiliary components. The plurality of main components is housed in at least one part of the at least one first compartment. The plurality of auxiliary components is housed in the cable compartment. The second connector is configured to connect to the first connector to connect a cable in the cable compartment to a component of the plurality of main components. The cable compartment is configured to be disconnected from the at least one first compartment and wherein the cable compartment is configured to be spatially separated from the at least one first compartment.Type: ApplicationFiled: October 13, 2022Publication date: February 2, 2023Applicant: ABB Schweiz AGInventors: Radek Javora, Tomas Kozel, Josef Cernohous, Michal Skuci

Publication number: 20220115195Abstract: A three-position disconnector switch includes an earthing contact, a power out contact, a power in contact, a piston, and a threaded rod. A length of the piston is such that in a first switch position an outer surface of a wall of the piston makes an electrical contact between the power out contact and the power in contact. The length of the piston is such that in a second switch position the outer surface of the wall of the piston does not make an electrical contact with either the earthing contact or the power in contact. The length of the piston is such that in a third switch position the outer surface of wall of the piston makes an electrical contact between the earthing contact and the power out contact. The piston includes an inner threaded section configured to engage with the threaded rod.Type: ApplicationFiled: December 20, 2021Publication date: April 14, 2022Applicant: ABB Schweiz AGInventors: Radek Javora, Dietmar Gentsch, Josef Cernohous, Michal Skuci, Tomas Kozel, Kai Gorlt

Publication number: 20220052512Abstract: An interlock system for a low, medium or high voltage switchgear includes: a compartment; a door; a door handle; and a circuit breaker. The door permits access to an inside of the compartment. The door handle opens and closes the door. The circuit breaker is located in the compartment. The door handle is movable from a closed position to an open position. When the door handle is in the closed position, the door does not to open, and when the door handle is in the open position, the door opens. A movement of the door handle from the closed position to the open position places the circuit breaker in a locked configuration.Type: ApplicationFiled: August 2, 2021Publication date: February 17, 2022Inventors: Michal Skuci, Josef Cernohous
