Publication number: 20170213673Abstract: The present invention relates to a refill-container for replenishing and/or reconditioning an insulation fluid contained in an insulation space of an electrical apparatus. At least a portion of the interior of the refill-container defines a refill-fluid containment space, in which a refill-fluid comprising an organo-fluorine compound is contained. According to the invention, the refill-container further comprises an opening designed to be brought from a sealed state, in which the refill-fluid is hermetically contained in the refill-containment space, to an open state, in which the refill-fluid is allowed to flow through the opening out of the refill-containment space into the insulation space.Type: ApplicationFiled: January 25, 2017Publication date: July 27, 2017Inventors: Arben Elshani, Denis Tehlar, Javier Mantilla Florez, Mathias-Dominic Buergler, Stephan Grob, Thomas Diggelmann

Patent number: 9177740Abstract: A gas-insulated high-voltage switch for the interruption of large currents includes a housing, a contact arrangement which is arranged in the housing and has two switching pieces which can be moved relative to one another along an axis. Each switching piece has a rated current contact and an arcing contact. The switch includes a drive which acts on a first of the two switching pieces. The switch includes a device configured to detect and indicate the contact wear of the two arcing contacts caused by the action of the arc. The device has an indicator arranged outside the housing. In the switch, the remaining life which is determined by the contact wear of the arcing contacts is detected and indicated by a simple mechanical mechanism. The device has a transmission mechanism which is fed through the housing in a gas-tight manner and a drive member coupled to the operating element.Type: GrantFiled: March 25, 2013Date of Patent: November 3, 2015Assignee: ABB TECHNOLOGY AGInventors: Javier Mantilla, Mathias-Dominic Buergler, Nicola Gariboldi, Stephan Grob

Patent number: 8901447Abstract: A circuit breaker is provided which can be filled with a quenching gas and which has two contact arrangements, which can be moved relative to one another and along a longitudinal axis of the circuit breaker. The contact arrangements form a arcing contact system and a rated current contact system connected electrically in parallel with it. One of the contact arrangements includes inner rated current contacts and outer rated current contacts of the rated current contact system, where the inner rated current contacts overhang the outer rated current contacts in the direction of the longitudinal axis, and the outer rated current contacts coaxially surround the inner rated current contacts. The circuit breaker has a high current carrying capability as well as a reliable switching-on and -off behavior, such as during and after the occurrence of a short-circuit current in the circuit breaker.Type: GrantFiled: September 23, 2010Date of Patent: December 2, 2014Assignee: ABB Technology AGInventors: Claudio Manzoni, Javier Mantilla, Nicola Gariboldi, Stephan Grob, Jasmin Smajic, Mathias-Dominic Buergler

Patent number: 8822868Abstract: A simplified construction of a gas-insulated high-power circuit breaker with a saving of components is achieved by at least one hole and at least one leaf spring, which is fastened on one side and is elastically bendable in dependence upon the pressure of the insulating gas in the compression volume, being formed in a valve plate of the valve. The bendable spring closes off the hole when the circuit breaker closes and opens it when the circuit breaker opens as soon as the pressure of the compressed insulating gas in the compression volume exceeds the value of the gas pressure in the low-pressure chamber by at least two bar.Type: GrantFiled: September 17, 2013Date of Patent: September 2, 2014Assignee: ABB Technology AGInventors: Timo Kehr, Olaf Hunger, Jurg Nufer, Daniel Ohlsson, Navid Mahdizadeh, Javier Mantilla, Stephan Grob, Mathias-Dominic Buergler, Nicola Gariboldi

Patent number: 8766131Abstract: A high-voltage switch includes a contact arrangement having two arcing contacts, one of which is supported displaceably against the action of a pretensioned spring. When the contact arrangement is closed, the free ends of the two arcing contacts are supported on one another. When the contact arrangement is opened, the two arcing contacts separate and during this process an arcing zone, accommodating compressed arc gas, is produced which is limited axially by free ends of the two arcing contacts and radially by an insulating nozzle toward the outside. To prevent the displaceably supported arcing contact from returning against the action of the pretensioned spring when a large short-circuit current is interrupted, the switch includes a piston/cylinder system functioning as a restoring device, which communicates with the arcing zone and which, with increasing pressure of the compressed arc gas produced in the arcing zone, generates a restoring force supporting the repelling force of the pretensioned spring.Type: GrantFiled: May 11, 2011Date of Patent: July 1, 2014Assignee: ABB Technology AGInventors: Javier Mantilla, Nicola Gariboldi, Stephan Grob, Oliver Cossalter, Mathias-Dominic Buergler
