Patent number: 10361024Abstract: A dry-type transformer core has an iron core with a number of limbs designed to be wrapped with a winding and interconnected by a number of magnetic yokes. The object is to produce a transformer of this type in a simple manner, which is especially well protected against corrosion. For that purpose, the dry-type transformer core includes a casing that is formed onto the iron core. The casing surrounds the iron core in a substantially flush manner.Type: GrantFiled: September 16, 2015Date of Patent: July 23, 2019Assignee: Siemens AktiengesellschaftInventor: Rudolf Hanov

Patent number: 8643458Abstract: A winding includes a wound electrical conductor having an electrical insulator. A method is also provided for producing a winding. The winding can be produced as a single piece by using a support on which the electrical conductor can be disposed and electrically insulated. The support is particularly implemented in the form of a cylindrical spiral as a coil, and thereby allows practically unlimited single-piece production of the winding. The cross section and/or the width of the electrical conductor can simultaneously be varied by location on the support.Type: GrantFiled: April 16, 2009Date of Patent: February 4, 2014Assignee: Siemens AktiengesellschaftInventor: Rudolf Hanov

Patent number: 8274350Abstract: An electrical winding body includes an electrically conductive winding and an insulation surrounding the winding. The surrounding insulation surrounds the entire winding and forms a mechanically stable winding body. At least one continuous channel having an opening in the electrical winding body is disposed inside the winding body. An extension element is placed in the openings of the continuous channels to elongate the channels beyond the dimensions of the electrical winding body, thus providing for improved cooling. Side elements are additionally attached on the outer wall of the electrical winding body to create an intermediate space which forms a new cooling channel that produces an additional cooling effect due to an air current created by the chimney effect.Type: GrantFiled: September 28, 2007Date of Patent: September 25, 2012Assignee: Siemens AktiengesellschaftInventors: Rudolf Hanov, Fritz Sorg

Patent number: 8085121Abstract: A transformer, in particular an entirely cast resin transformer, includes at least one lower voltage winding and at least one upper voltage winding. The application of an electrical shielding around the upper voltage winding makes it possible to prevent a voltage disruptive discharge in such a way that the outer wall of the transformer can be touched by a person and also provides the transformer with electromagnetic shielding. The transformer is provided with bushings for internal electric connections and for that reason, it can be placed in media affected by dirty surroundings and in open air.Type: GrantFiled: March 23, 2006Date of Patent: December 27, 2011Assignee: Siemens AktiengesellschaftInventor: Rudolf Hanov

Publication number: 20110210812Abstract: A holding device for fastening a cast resin transformer winding relative to a transformer core has a support element and a receiving element attached to a tie rod. By fastening the support element to the receiving element attached to the tie rod, a cast resin transformer winding can be fixed rigidly and precisely centered relative to a transformer core. By attaching the receiving element directly on the tie rod, circulation in the lower region of the cast resin transformer winding or of an insulating cylinder also attached to the support element is ensured and thereby the thermal properties of a cast resin transformer winding produced in this way are improved. Furthermore a modular and thus simple design of the cast resin transformer is possible due to the possibility of connecting the receiving element to the tie rod by way of the support element.Type: ApplicationFiled: October 5, 2009Publication date: September 1, 2011Applicant: SIEMENS AKTIENGESELLSCHAFTInventors: Karl-Heinz Charwat, Rudolf Hanov

Publication number: 20080290981Abstract: An electrical winding can be arranged concentrically around a magnet core. A novel transformer includes at least one magnet core and at least one electrical winding, wherein the electrical winding can be arranged concentrically around the magnet core. The electrical windings are connected fixedly to a fixing apparatus, wherein the fixing apparatus can be fixed in a radial plane. As a result, subsequent fixing of the electrical windings in relation to one another and in relation to the magnet core which is to be reinforced mechanically is dispensed with.Type: ApplicationFiled: November 20, 2006Publication date: November 27, 2008Applicant: SIEMENS AKTIENGESELLSCHAFTInventors: Joachim Bischoff, Karl-Heinz Charwat, Rudolf Hanov, Peter Olschewski, Richard Sille
