Patent number: 11742169Abstract: An ultra-fast moving conductor for use with a circuit breaker is provided. The moving conductor includes a hollow outer stem and a removable core. Multiple removable cores are produced for use with the moving conductor for different purposes. The outer stem is produced from annealed copper that must be brazed before the circuit breaker is placed into operation, and a first removable core produced from copper is inserted into the outer stem to provide structural reinforcement to the outer stem during brazing. After brazing is complete, the copper core is removed from the outer stem, and a significantly lighter work hardened aluminum core is inserted into the outer stem. The lightweight aluminum core enables the moving conductor to open the circuit breaker much faster than the copper core would, and the copper core prevents contamination of the brazing furnace that would result from using the aluminum core during brazing.Type: GrantFiled: December 15, 2021Date of Patent: August 29, 2023Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Andrew L. Gottschalk, Robert Michael Slepian, Ganesh Kumar Balasubramanian, Andrew Deutsch

Patent number: 11673298Abstract: A mold for encapsulating an electrical component. The mold includes an encapsulation chamber and an air inlet. The encapsulation chamber is defined by a housing, an open top, and a solid bottom. The housing includes a solid outer wall, a permeable inner wall, and an air chamber between the solid outer wall and the inner wall. The air inlet is configured to introduce a gas into the air chamber. The encapsulation chamber is sized and shaped to receive the electrical component while leaving a gap for the introduction of encapsulant around the electrical component. The encapsulant may be silicone rubber. To remove an encapsulated electrical component, pressurized air may be introduced through the air inlet into the air chamber, passing through the permeable inner wall, separating the outer surface of the encapsulant from the housing, and allowing the combination casting to be removed from the mold.Type: GrantFiled: March 25, 2022Date of Patent: June 13, 2023Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Louis G. Campbell, Ganesh Kumar Balasubramanian

Patent number: 10804044Abstract: An improved electrical contact alloy, useful for example, in vacuum interrupters used in vacuum contactors is provided. The contact alloy according to the disclosed concept comprises copper particles and chromium particles present in a ratio of copper to chromium particles of 2:3 to 20:1 by weight. The electrical contact alloy also comprises particles of a carbide, which reduces the weld break strength of the electrical contact alloy without reducing its interruption performance.Type: GrantFiled: September 27, 2019Date of Patent: October 13, 2020Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Louis Grant Campbell, Ganesh Kumar Balasubramanian, Benjamin Alex Rosenkrans

Patent number: 10796867Abstract: An electrode assembly for a vacuum interrupter includes a contact plate, an electrode coil, an inner support, a lower support, and at least one support member. The electrode coil includes a base for attachment to a terminal post of the vacuum interrupter. The electrode coil also includes at least one arcuate arm between the base and the contact plate extending along a curved path in a plane substantially perpendicular to a direction of travel of the electrode assembly. Each arcuate arm includes an aperture that is positioned to align with a corresponding aperture of an adjacent arcuate arm or the base of the electrode coil. Each support member is partially positioned within aligned apertures to maintain a gap between the arcuate arms and the base. The support members and the lower support may be slotted to decrease the current flowing through the supports.Type: GrantFiled: September 17, 2019Date of Patent: October 6, 2020Assignee: Eaton Intelligent Power LimitedInventors: Wangpei Li, Eric D.
