Publication number: 20240145186Abstract: A dual conductor Thomson coil actuator for use in opening the separable contacts of a circuit interrupter comprises two nested conductors wound to form a single coil, rather than the traditional design comprising one single conductor wound to form a coil of the same size. Each of the two conductors can be excited by half the capacitance that would be used to excite the traditional single conductor coil, using the same voltage as the single conductor coil. When the same total capacitor-stored energy that would be used to excite the single conductor coil is instead used to excite the dual conductor coil, the initial pulse of aggregate current through the dual conductor coil is greater than the initial pulse of current through the single conductor coil, resulting in a faster initial opening distance of the separable contacts during an opening stroke.Type: ApplicationFiled: October 28, 2022Publication date: May 2, 2024Applicant: EATON INTELLIGENT POWER LIMITEDInventors: Asish Das, Santhosh Kumar Chamarajanagar Govinda Nayaka, Robert Michael Slepian, Xin Zhou

Publication number: 20240062956Abstract: An assembly for manufacturing the insulation layer of a Thomson coil includes a base plate, a coil housing, and a cover plate. The base plate securely seats the coil housing, and the coil housing securely seats a Thomson coil and the cover plate. The cover plate has several ribs that hold multiple turns of a Thomson coil in place while epoxy is applied to the coil, thus ensuring that the epoxy is evenly distributed on the coil surface and that the coil windings remain level. The cover plate and coil housing are structured to either receive a high-pressure epoxy injection or to be used in an epoxy potting process, during which all exposed areas of the Thomson coil are coated by liquid epoxy. After the epoxy has solidified, the Thomson coil is coupled to the coil housing, and the housed and insulated Thomson coil is removed from the assembly.Type: ApplicationFiled: August 10, 2023Publication date: February 22, 2024Applicant: EATON INTELLIGENT POWER LIMITEDInventors: Xin Zhou, Santhosh Kumar Chamarajanagar Govinda Nayaka, Robert Michael Slepian, Zhixi Deng

Patent number: 11749477Abstract: A circuit breaker includes a vacuum interrupter. The interrupter includes a first movable electrode to which a first contact is connected and a second movable electrode to which a second contact is connected. The interrupter is operable between an open state and a closed state. In the open state, the first contact and the second contact are separated by a contact gap distance. In the closed state, the first contact and the second contact touch each other. The circuit breaker includes an ultrafast actuator operatively connected to each of the first and second movable electrodes. The ultrafast actuator is configured to change the vacuum interrupter from the closed state to the open state by simultaneously moving the first contact in a first direction along a first distance portion of the contact gap, and the second contact in a second direction along a second distance portion of the contact gap.Type: GrantFiled: April 21, 2021Date of Patent: September 5, 2023Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Asish Das, Santhosh Kumar Chamarajanagar Govinda Nayaka, Andrew L.

Patent number: 11749480Abstract: A latching assembly for latching the moving conductor assembly of a circuit interrupter after an opening stroke includes a streamlined latch that omits components commonly prone to damage during latching operations in existing latching assemblies. The disclosed latching assembly comprises a fixed latch block, a driven latch rotatably coupled to the latch block, and a pivoting hammer with a square pin positioned to always be engaged with the driven latch. The latching assembly is structured to be engaged by a switch shaft once an opening stroke is initiated. When the latching assembly engages, the hammer square pin pushes the driven latch into engagement with a shelf formed in the switch shaft, which prevents the switch shaft from rebounding after the opening stroke. Rebounding is further prevented due to the hammer being structured to be biased toward the open state once the driven latch has engaged the switch shaft shelf.Type: GrantFiled: June 10, 2022Date of Patent: September 5, 2023Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Andrew L.

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.

Patent number: 11696420Abstract: A cooling device for use with circuit interrupters includes a housing structured to be coupled to a terminal of the circuit interrupter and formed with several ventilation openings, as well as a permanent magnet, a torque converter and a fan blade all contained within the housing. When the cooling device is coupled to a terminal of a circuit interrupter and current flows through the terminals of the circuit interrupter, parasitic magnetic fields are generated and induce oscillatory motion of the permanent magnet. The torque converter is coupled to the permanent magnet and converts the oscillatory motion of the magnet to rotational motion that rotates the fan blade. The fan blade is disposed near the ventilation openings of the housing so that air flow produced by rotation of the fan blade travels across the surface of the circuit interrupter terminal nearest the ventilation openings to increase convection.Type: GrantFiled: July 8, 2021Date of Patent: July 4, 2023Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Avadhoot Kittur, T.

Patent number: 11657986Abstract: An electrical switching device, such as a high-speed switching device, has a damper and latching assembly. The assembly is configured to dampen the movement of a moving contact of the switching device as the moving contact translates from its closed position to its open position. The assembly also is configured to restrain the moving contact in its open position. The assembly stores at least some of the energy associated with the damping process, and uses the stored energy to assist in the release of the moving contact during the subsequent re-closing of the switching device.Type: GrantFiled: July 26, 2021Date of Patent: May 23, 2023Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Andrew L.

Patent number: 11631562Abstract: A closing spring assembly for an electrical switching device is provided. The closing spring assembly is configured to exert a closing force on a moving contact of the switching device. The closing force helps to maintain physical and electrical contact between the moving contact and an associated stationary contact, so that the moving and stationary contacts form a path for conducing electric current through the switching device. The closing spring assembly is configured so that the closing force remains constant or decreases as the moving contact is driven away from the stationary contact during switching of the current path away from the moving and stationary contacts.Type: GrantFiled: February 19, 2021Date of Patent: April 18, 2023Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Andrew L.
