Patent number: 8420971Abstract: A switching chamber insulation arrangement and a circuit breaker having such a switching chamber insulation arrangement are provided. The switching chamber insulation arrangement provides improved heat dissipation in the area of the contact areas of switch contact poles. The switching chamber insulation arrangement includes a strut arrangement having a plurality of struts. Each strut has a first foot area, a second foot, area and a center area which is located between the first foot area and the second foot area, respectively. The struts are arranged along a circumference around a longitudinal extent axis of the strut arrangement. The strut arrangement has a first mechanical coupling area on a side of the first foot areas for coupling to a first pole of a circuit breaker, and a second mechanical coupling area on a side of the second foot areas for coupling to a second pole of a circuit breaker.Type: GrantFiled: May 27, 2011Date of Patent: April 16, 2013Assignee: ABB Technology AGInventors: Roland Würgler, Arben Sabani, Vincent Tilliette, Walter Holaus, Markus Keller, Diego Sologuren-Sanchez, René Kallweit

Patent number: 8150230Abstract: A high-voltage bushing has a conductor and a core surrounding the conductor, wherein the core comprises a sheet-like spacer, which spacer is impregnated with an electrically insulating matrix material. The spacer is wound in spiral form around an axis, the axis being defined through the shape of the conductor. Thus, a multitude of neighboring layers is formed. The core further comprises equalization elements in appropriate radial distances to the axis. The equalization elements comprise electrically conductive layers, which layers have openings, through which openings the matrix material can penetrate, and in that the equalization elements are applied to the core separately from the spacer. The electrically conductive layers can be net-shaped, grid-shaped, meshed or perforated. The openings are fillable with the matrix material, e.g., a particle-filled resin can be used.Type: GrantFiled: June 13, 2008Date of Patent: April 3, 2012Assignee: ABB Research LtdInventors: Vincent Tilliette, Jens Rocks, Stefan Gisy, Roger Hedlund, Gerd Chalikia, Ruedi Meili

Patent number: 8003891Abstract: An exemplary high-voltage outdoor bushing is disclosed which includes a conductor extended along an axis, a condenser core and an electrically insulating polymeric weather protection housing molded on the condenser core. The condenser core can contain an electrically insulating tape which is wound in spiral form around the conductor. Capacitance grading insertions can be arranged between successive windings of the tape. A cured polymeric insulating matrix embeds the wound tape and the capacitive grading insertions. A moisture diffusion barrier can be incorporated inside the condenser core prior to molding the weather protection housing.Type: GrantFiled: April 23, 2010Date of Patent: August 23, 2011Assignee: ABB Research LtdInventors: Jens Rocks, Vincent Tilliette, Walter Odermatt, Willi Gerig

Patent number: 7812266Abstract: A bushing is disclosed with a duct for accommodating a conductor which is surrounded by an electrical field grading insulation. The bushing includes a core with a shell encapsulating the grading insulation and a flange surrounding the shell and carrying through holes distributed over its circumference for allowing the bushing to be attached to a wall. The shell and the flange can be in one piece and include an insulating matrix material. The through holes can be surrounded by metal inserts each forming an annular surface flush with a surface of the flange. A test tap can include a contact pin which is electrically conductively connected to an outermost layer of the grading insulation and surrounded by a contact ring connected to every second metal insert by connection wires for grounding the contact pin via the contact ring when the test tap is not in use and covered.Type: GrantFiled: June 18, 2009Date of Patent: October 12, 2010Assignee: ABB Research LtdInventors: Jens Rocks, Vincent Tilliette, Gerd Chalikia, Roger Hedlund, Michael Gabriel
