Publication number: 20230012290Abstract: 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: ApplicationFiled: July 8, 2021Publication date: January 12, 2023Applicant: EATON INTELLIGENT POWER LIMITEDInventors: Avadhoot Kittur, T.

Publication number: 20220344115Abstract: 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: ApplicationFiled: April 21, 2021Publication date: October 27, 2022Inventors: Asish Das, Santhosh Kumar Chamarajanagar Govinda Nayaka, Andrew L.

Publication number: 20220270839Abstract: 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: ApplicationFiled: February 19, 2021Publication date: August 25, 2022Inventors: Andrew L.

Publication number: 20210296060Abstract: A solid state circuit interrupter provides structures which can manually move an isolation switch of a pole from the ON state to the OFF state without the use of auxiliary power but that advantageously additionally provides an interlock apparatus that avoids manually moving the isolation switch from the ON state to the OFF state until certain conditions exist. One such condition is to ensure that some action is taken, such as by switching a physical interlock between one state and another state. Such a change in state of the physical interlock might additionally result in a change in state of an electronic interlock that would resist the solid state switch being moved to its ON state while the isolation switch is capable of being manually switched to its OFF state. The physical interlock might additionally resist the isolation switch from being manually switched into its ON state.Type: ApplicationFiled: March 23, 2020Publication date: September 23, 2021Applicant: EATON INTELLIGENT POWER LIMITEDInventors: Andrew L.
