Publication number: 20230230785Abstract: A medium voltage load break switch includes a main contact and a knife. The knife is rotatable about a pivot point to connect to and be in contact with the main contact and to rotate about the pivot point to disconnect from and be spaced from the main contact. The load break switch also comprises a vacuum interrupter that has a fixed contact and a moveable contact. A lever rotates about a rotation point and a shaft of the moveable contact is aligned along an axis of the vacuum interrupter, and the shaft of the moveable contact is linked to the lever.Type: ApplicationFiled: March 22, 2023Publication date: July 20, 2023Applicant: ABB Schweiz AGInventors: Maik Hyrenbach, Sebastian Breisch, Ondrej Frantisek

Patent number: 10643814Abstract: A medium voltage circuit breaker in a high pressure subsea environment includes: a vacuum circuit breaker; and a drive in a pressure tight housing. For an electrical three-phase arrangement, one vacuum circuit breaker per phase is arranged in a separate pole housing each, and the resulting three pole housings are mounted to a common base compartment, in which three drives for the three vacuum circuit breakers are arranged. The three pole housings and the common base compartment are attached such that they commonly form a pressure tight compartment.Type: GrantFiled: December 14, 2017Date of Patent: May 5, 2020Assignee: ABB SCHWEIZ AGInventors: Pravin Futane, Paul Midtun, Knut S.

Patent number: 10529510Abstract: In an embodiment, the present invention provides a gas insulated switchgear for medium- or high-voltage use, including: a closed housing of a switchgear compartment having insulating gases or fluids. The insulation gas includes sulfurhexaflouride (SF6). Constructive features of the switchgear are designed such that they are overperformed for the use of sulfurhexaflouride (SF6), but already sufficiently performed for the use of eco efficient insulation gas with a mixture of up to 20% fluoroketone C5F10O and air or oxygen and carbondioxide. A later retrofit or adaption to a switchgear, filled with eco-efficient insulation gas, only needs the aforesaid gas exchange, without exchanging constructive parts of the switchgear.Type: GrantFiled: January 11, 2018Date of Patent: January 7, 2020Assignee: ABB SCHWEIZ AGInventor: Maik Hyrenbach

Patent number: 9460868Abstract: An exemplary assembled pole part includes two pole part frames made of insulating material, between which a vacuum interrupter is mounted. The vacuum interrupter includes a fixed contact and a moving contact. The frame includes a first support to affix the vacuum interrupter at the moving contact side, and a second support to affix the vacuum interrupter to the fixed contact side at an opposite end of the frame. In order to apply common pole part frames for different vacuum interrupter sizes, in order to alleviate the manufacture of such pole parts, at least two fixation points are arranged pairwise in parallel along different distances along the long axis of the frame. The first support at the moving contact side maintains a specified fixation position, so the frame is configured for use with at least one other vacuum interrupter of a different length.Type: GrantFiled: April 15, 2015Date of Patent: October 4, 2016Assignee: ABB Schweiz AGInventors: Maik Hyrenbach, Manfred Sauer

Patent number: 9343881Abstract: A gas-insulated switchgear assembly is provided that includes a housing having an interior containing insulating gas. A disconnector is disposed in the housing and includes a movable contact, as well as fixed contacts that are spaced apart and arranged linearly in a direction perpendicular to a wall of the housing. The movable contact has a colored or topographical marking and is linearly movable among a plurality of positions. The wall of the housing is provided with an inspection window that permits a person to see the colored or topographical marking in relation to the fixed contacts, thereby permitting the person to determine the position of the movable contact.Type: GrantFiled: February 19, 2013Date of Patent: May 17, 2016Assignee: ABB Technology AGInventors: Maik Hyrenbach, Kasimir Mai
