摘要： Various embodiments of the teachings herein include a corona shielding tape for further processing to give an insulation system comprising an impregnated winding with potential control via outer corona shielding “AGS” and/or internal potential controller “IPS” and/or terminal corona shielding “EGS”, the insulation system being producible by impregnating the winding with an anhydride-free and resin-based impregnating agent at 45-85° C. and under reduced pressure. The corona shielding tape may include: a carrier tape; an electrically conductive and/or partly conductive filler in a polymer matrix; and a tape accelerator suitable for curing and/or gelation of the impregnating agent. The polymer matrix contains at least one polyvinylalcohol and/or a polyvinylalcohol copolymer. The accelerator is selected from the group consisting of: superacids and superacid salts suitable for acceleration of a cationic homopolymerization of the resin-based anhydride-free impregnating agent.

摘要： 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.

摘要： An electric switching device may include at least two conductor elements that can be placed at a distance from one another and contacted with each other using a moving mechanism, and a housing that defines a circuit breaker chamber, wherein the housing is made of an insulator, and at least partly surrounds the conductor elements. At least one face of the housing may have a resistive coating made of a matrix material filled with a filler, wherein the coating has a sheet resistance between 108 and 1012 ohm at the operating field strength, and is conductingly connected to the conductor elements.

摘要： The present disclosure relates to a corona shielding material. The teachings thereof may be embodied in a material with an adjustable resistance and/or a corona shielding system which comprises an overhang corona shielding system (OCS). In some embodiments, a corona shielding material may include: a matrix; and a filler comprising doped and undoped particles in a given size fraction. A resistance of the corona shielding material is set by a concentration of doped particles in the filler particle size fraction.

摘要： Various embodiments include an impregnation formulation for a wrapping tape insulation of an electrical machine. The formulation comprises: a resin formulation with an epoxy base resin and a first component; and a hardener formulation with a hardener. The resin formulation reacts when combined with the hardener formulation to produce an insulation material. The first component includes a saturated and/or unsaturated epoxycycloalkyl group. A glass transition temperature of the insulation material is elevated compared to an impregnation formulation without the first component.
