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: 8797133Abstract: A coil and electric shielding arrangement for a dry-type transformer includes an electric shielding device arranged at a distance from a winding, at an axial end of the winding perpendicular to a longitudinal axis of the transformer, and parallel to a top surface of a coil that is wound around the axis such that the electric shielding device covers a cross-sectional area of the winding perpendicular to the longitudinal axis. An insulation material attached to the winding and to the electric shielding device establishes a first distance between the winding and the electric shielding device along the longitudinal axis such that the winding is shielded against another electric field. The winding and the electric shielding device are casted in a block which insulates the electric shielding device from the electric field of the winding by establishing a second distance between the winding and the electric shielding device.Type: GrantFiled: December 27, 2012Date of Patent: August 5, 2014Assignee: ABB Technology Ltd.Inventors: Rafael Murillo, Carlos Roy, Jasmin Smajic, Lise Donzel, Jens Tepper, Jesús Letosa Fleta, Antonio Usón, Maria Teresa Villen, Miguel Samplon

Publication number: 20130021709Abstract: A conductor arrangement is provided for reducing very fast transients in high voltage applications. The conductor arrangement includes a conductor element having a main conducting orientation, and a conductive annular shell element coaxial to the conductor element, thus forming an annular cavity around the conductor element. The annular shell element in the main conducting orientation includes a first end portion and a second end portion. The first end portion is conductively connected to the conductor element. The second end portion includes an annular collar which is substantially coaxial to the conductor element, thus together with the conductor element forming a coaxial capacitor which has a solid material filling. The capacitor includes a surge arrester which may serve as an energy conversion portion.Type: ApplicationFiled: July 19, 2012Publication date: January 24, 2013Applicant: ABB TECHNOLOGY AGInventors: Jasmin Smajic, Walter Holaus, Martin Seeger, Felix Greuter, Arthouros Iordanidis, Uwe Riechert
