Patent number: 11842871Abstract: The switch contacts of a MEMS relay for a circuit interrupter are coated with a thin layer of liquid metal, and the MEMS relay is disposed in a sealed enclosure containing a gas medium. The gas medium provides an environmentally desirable alternative to sulfur hexafluoride (SF6), prevents oxidation of the liquid metal coating the relay switch contacts, and has sufficient dielectric strength in order to prevent current flow after separation of the switch contacts.Type: GrantFiled: September 15, 2021Date of Patent: December 12, 2023Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Stanislav Kadlec, Sandy Omar Jimenez Gonzalez, Venkat raman Thenkarai Narayanan, Mykhailo Gnybida, Christian Ruempler

Patent number: 11742165Abstract: A switching device for guiding and switching of load currents includes: a movable switching component having a first movable contact and a second movable contact; a first fixed contact and a second fixed contact; a supporting device for supporting the switching component; and a magnetic actuator. The first movable contact is in contact with the first fixed contact and the second movable contact is in contact with the second fixed contact in a switched-on state of the switching component. The first movable contact is electrically separated from the first fixed contact and the second movable contact is electrically separated from the second fixed contact in a switched-off state of the switching component. The switching component is arranged such that the switching component moves between the switched-on state and the switched-off state by at least a rotational movement of the switching component and a translational movement of the supporting device.Type: GrantFiled: December 16, 2019Date of Patent: August 29, 2023Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Lutz Friedrichsen, Christoph Bausch, Julia Otte, Kai Schroeder, Johannes Meissner, Christian Ruempler, Albert Zacharias

Patent number: 10128069Abstract: A debris barrier is for an electrical switching apparatus. The electrical switching apparatus includes separable contacts and an arc chute. The separable contacts generate debris when tripping open in response to an electrical fault. The arc chute has a plurality of splitter plates each having an edge portion and a distal portion located opposite and distal the edge portion. The debris barrier includes a first leg, a second leg, and a middle portion connecting the first leg and the second leg. The middle portion is coupled to one of the separable contacts. At least one of the first leg and the second leg has a first barrier portion and a second barrier portion extending therefrom. The first barrier portion is located proximate the distal portion. The second barrier portion extends from the first barrier portion toward the edge portion in order to redirect the debris toward the edge portion.Type: GrantFiled: July 18, 2017Date of Patent: November 13, 2018Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Christian Ruempler, Brian John Schaltenbrand, Andrew Lawrence Gottschalk, Richard Paul Malingowski, Kelly Julia McCarthy, Xin Zhou

Patent number: 10079121Abstract: A system for switching gases appearing after a short-circuit switching procedure in electrical service devices, particularly in low-voltage power switches, includes a switching gas cooling assembly and particle capture arrangement. Downstream of the flow path of switching gases issuing from at least one switching chamber outlet window, the switching gas cooling assembly is arranged in a blow-out chamber. In the space behind the at least one switching chamber outlet window and prior to entry of the switching gases into the switching gas cooling assembly, there is arranged a flow element around which the switching gases can flow and which has a cross section which corresponds to or is greater than the cross section of the switching chamber outlet window. The flow elements act as the particle capture arrangement and thus as a protection device for the switching gas cooling arrangement.Type: GrantFiled: October 26, 2015Date of Patent: September 18, 2018Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Albert Zacharias, Christian Ruempler

Publication number: 20160293352Abstract: A method for producing plate arrangements and using these for cooling gaseous blow-off in electric installation devices, produces a plate stack, which is formed in a cuboidal shape, with a stack length and a stack width. The plate stack is made of shaped rectangular sheets which are produced using a shaping process and are sheet-metal strips of a uniform thickness. First shaped sheets with a uniform length which corresponds to the stack length and second shaped sheets with a width which corresponds maximally to the stack width are used. The shaped sheets are stacked one on top of the other after being shaped such that multiple continuous cavities, i.e., slots, are formed in the longitudinal direction of the stack parallel to the uniform length, and the shaped sheets are connected to one another in a captive mariner so as to form a self-supporting structure of a plate stack.Type: ApplicationFiled: October 21, 2014Publication date: October 6, 2016Inventors: Albert Zacharias, Christian Ruempler
