Patent number: 11081923Abstract: The present disclosure relates to electrical machines. The teachings thereof may be embodied in a corona shielding system for an electrical machine. For example, a corona shielding system may include: an outer corona shield and an overhang corona shielding. The outer corona shielding and the overhang corona shielding may comprise a first corona shielding material having a nonlinear field strength-dependent electrical resistance.Type: GrantFiled: August 3, 2015Date of Patent: August 3, 2021Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Bernhard Klaussner, Jiri Lang, Steffen Lang, Alexander Litinsky, Guido Schmidt, Christian Schulz-Drost, Klaus Schaefer, Christian Staubach

Patent number: 10862362Abstract: The present disclosure relates to electrical machines. The teachings thereof may be embodied in a corona shielding system, especially for an electrical machine, e.g., a high-voltage machine, such as a generator for generation of electrical energy, an electric motor, or another piece of electrical equipment having a relatively high rated voltage, e.g., a transformer or a bushing or a cable. A corona shielding system may include: a polymeric matrix; and filler particles comprising mica surrounded by a layer of at least one ceramic metal oxide. The filler particles may be distributed throughout the polymeric matrix.Type: GrantFiled: August 3, 2015Date of Patent: December 8, 2020Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Bernhard Klaussner, Jiri Lang, Steffen Lang, Alexander Litinsky, Guido Schmidt, Christian Schulz-Drost, Klaus Schaefer, Christian Staubach

Patent number: 10673294Abstract: The present disclosure relates to electrical machines. The teachings thereof may be embodied in a corona shielding system, especially an outer corona shielding system, for an electrical machine. For example, a corona shielding system may include: a polymeric matrix; particles disposed in the matrix, including a mica-coated core and a layer of metal oxide disposed on the core; and a surface functionalization material disposed on a surface of the particles for binding to the matrix.Type: GrantFiled: August 3, 2015Date of Patent: June 2, 2020Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Bernhard Klaussner, Jiri Lang, Steffen Lang, Alexander Litinsky, Guido Schmidt, Christian Schulz-Drost, Klaus Schaefer, Christian Staubach

Patent number: 10506748Abstract: A corona shielding system for an electric machine, for example a high-voltage machine, such as a generator, for generating electrical energy, an electric motor or else other electric operating means having a relatively high rated voltage, such as transformers, bushings, cables, etc, is disclosed. The corona shielding system may include a filler mixture including both planar and spherical particles. Therefore, the electrical conductivity, which is good in the presence of only planar particles in two spatial directions but is very poor in the third, can be adjusted anisotropically in a targeted manner.Type: GrantFiled: February 25, 2015Date of Patent: December 10, 2019Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Bernhard Klaussner, Jiri Lang, Steffen Lang, Alexander Litinsky, Guido Schmidt, Christian Schulz-Drost, Klaus Schaefer, Christian Staubach

Patent number: 7838575Abstract: High performance bituminous mixtures that are useful for the road paving and roofing industries comprise mineral aggregates coated with a thermoplastic polymer composition. Because of their high performance properties, the absence of any aggressive and toxic adhesion promoters and the possibility of using recovered or recycled thermoplastic polymers to form the coating or “membrane,” the bituminous mixtures described herein provide an excellent environmentally friendly solution for pavement construction and roofing industries.Type: GrantFiled: December 19, 2008Date of Patent: November 23, 2010Assignee: E. I. du Pont de Nemours and CompanyInventors: Jiri Lang, Stephen L. Cluff
