Patent number: 11251003Abstract: The application relates to certain embodiments of an improved insulating support assembly for a circuit breaker. One embodiment comprises a strut and two metallic shields. The strut comprises an elongated main body and two metallic inserts. The main body is continuously curved from one end to the other end of the main body, each end of the main body being configured to face a radial direction of its component, the main body being configured to be in a same plane as a plane containing both radial directions of the components; each metallic shield is configured to be assembled to its respective end of the main body through its respective metallic insert and affixed to an outer surface of its respective component with fixing elements, each metallic shield having a C-shaped profile shaped to accommodate the outer surface of its respective component.Type: GrantFiled: November 6, 2020Date of Patent: February 15, 2022Assignee: General Electric Technology GmbHInventors: Andrew Chovanec, Victor F. Hermosillo, Chase Colton Peltier

Patent number: 11127550Abstract: A contact arrangement for a Pre-Insertion Resistor (PIR) wherein a control rod is arranged to move a movable contact, against the force of a biasing member, into temporary connection with a PIR. The control rod comprises a tulip with a plurality of resilient fingers and having a first diameter where it is able to mechanically couple to a latching ring on the movable contact, and a second diameter where the tulip is deformed with the fingers deflected inwards, once the resistance to movement exceeds a predetermined value, wherein the latching ring is able to pass over the tulip to decouple the movable contact from the control rod. The contact arrangement is particularly suited for a PIR arranged for connection in parallel to the interrupter of a gas-insulated switchgear (GIS) circuit breaker.Type: GrantFiled: June 4, 2020Date of Patent: September 21, 2021Assignee: General Electric Technology GmbHInventors: Keith McLaughlin, Ludovic Darles, Jérôme Laurent, Thomas Tometich, Andrew Chovanec, Chase Peltier

Publication number: 20200388454Abstract: The invention concerns a contact arrangement (50) for a Pre-Insertion Resistor (PIR) wherein a control rod (20) is arranged to move a movable contact (30), against the force of a biasing member (18), into temporary connection with a PIR. The control rod (20) comprises a tulip (21) with a plurality of resilient fingers (24) and having a first diameter where it is able to mechanically couple to a latching ring (31) on the movable contact (30), and a second diameter where the tulip (21) is deformed with the fingers (24) deflected inwards, once the resistance to movement exceeds a predetermined value, wherein the latching ring (31) is able to pass over the tulip (21) to decouple the movable contact (30) from the control rod (20). The contact arrangement (50) is particularly suited for a PIR arranged for connection in parallel to the interrupter of a gas-insulated switchgear (GIS) circuit breaker.Type: ApplicationFiled: June 4, 2020Publication date: December 10, 2020Inventors: Keith MCLAUGHLIN, Ludovic DARLES, Jérôme LAURENT, Thomas TOMETICH, Andrew CHOVANEC, Chase PELTIER

Patent number: 9673006Abstract: A gas exhaust diffuser for a circuit breaker, comprising a first casing extending longitudinally along a principal axis with an open end to allow gas to enter and a closed end, and a second casing coaxial to the first casing, extending along the principal axis, with at least one outlet to allow gas to escape, the closed end of the first casing being arranged in the second casing and the first casing having at least two radial openings near its closed end to provide a fluid communication between the first and second casing. A plurality of incurved elements are positioned radially in the second casing at the at least one radial opening to create a rotation of an entering exhaust flow in a plan perpendicular to the principal axis, thereby generating a substantially helicoidally-shaped exhaust flow path in the second casing.Type: GrantFiled: January 23, 2015Date of Patent: June 6, 2017Assignee: ALSTOM TECHNOLOGY LTDInventors: Victor F.
