Patent number: 10923888Abstract: Modular switchgear systems are provided including at least two separate modules including components of switchgear. The at least two separate modules are independent of one another. One of the at least two separate modules is a stationary module and remaining ones of the at least two separate modules are removable such that the remaining ones of the at least two separate modules are configured to engage and/or disengage easily from the stationary module and an electrical power system. Related removable modules are also provided.Type: GrantFiled: March 12, 2018Date of Patent: February 16, 2021Assignee: Eaton Intelligent Power LimitedInventors: Bryan Richard Benson, Michael Patrick Culhane, Marten Binnendijk, David Allan Aho, Brent David Henry, David Glenn Woolard

Patent number: 10297986Abstract: An arc-resistant electrical enclosure includes an arresting system that permits forced-air cooling of the interior region to occur during ordinary operation of the enclosure while resisting the flow of hot gases, plasma, and flames to the exterior of the electrical enclosure in an arc event or other event. The arresting system advantageously includes a louver apparatus and a cover apparatus that work in conjunction to resist the flow of gases, plasma, and flames to the exterior of the cabinet in an arc event. The louver apparatus includes louvers that can be moved from an open state to a closed state responsive to a predetermined fluid pressure impinging on the louvers. The cover apparatus includes a fire blocking panel that permits fluid flow therethrough during ordinary operation but which, responsive to a flame, initiates a transformation from one state to another state wherein the openings resist the communication of flames therethrough.Type: GrantFiled: August 31, 2015Date of Patent: May 21, 2019Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Wesley Byron Johnson, David Glenn Woolard

Patent number: 10178803Abstract: An apparatus includes at least one evaporator having a surface configured for mounting of a power electronic device thereon, a condenser fluidically coupled to the at least one evaporator by at least two coolant conduits that electrically insulate the at least one evaporator from the condenser, and a dielectric coolant contained in a thermosyphon loop comprising the at least one evaporator, the condenser and the at least two coolant conduits. The at least one evaporator may include at least two evaporators fluidically coupled by at least one coupler that electrically insulates the at least two evaporators from one another. The at least one evaporator may be housed within an enclosure, and the condenser may be positioned within the enclosure or outside of the enclosure.Type: GrantFiled: March 11, 2016Date of Patent: January 8, 2019Assignee: Eaton Intelligent Power LimitedInventors: Abhinav Dixit, Atul Singhal, David Glenn Woolard, Tarun Malik
