Patent number: 11984711Abstract: A method for producing an electrical power device from subsequently manufactured parts by an additive manufacturing technique includes determining a target spatial distribution of a physical property of the electrical power device, the physical property being an electrical property and/or a mechanical property; forming a part of the electrical power device; selecting a physical property of a subsequent part of the electrical power device corresponding to the determined spatial distribution of the physical property such as to be different from a corresponding physical property of the part; and by means of the additive manufacturing technique, forming the subsequent part such that it is at least partially in contact with the part. An electrical power device is obtainable by the method, and the electrical power device may be used as an AC or DC insulator in an HVAC or HVDC apparatus.Type: GrantFiled: March 22, 2019Date of Patent: May 14, 2024Assignee: HITACHI ENERGY LTDInventors: Pierre Elser, Lukasz Matysiak, Robert Sekula, Francesco Agostini

Publication number: 20230071110Abstract: The present disclosure relates to a bushing including an electrical conductor comprising a terminal at a first end of the bushing. The bushing also includes an electrically insulating condenser core arranged around the conductor and defining a central longitudinal through-hole through which the conductor extends. The bushing also includes a plurality of concentric field-grading layers arranged in the condenser core, comprising an inner field-grading layer and an outer field-grading layer. The bushing also includes an electrically conductive head electrically connected with the conductor passing there through, forming a gas-tight cap of the first end of the bushing outside of the condenser core, sealingly engaging a circumferential lateral outer surface of the condenser core and sealingly engaging the conductor. The bushing also includes an electrically conductive connection between the inner field-grading layer and the head.Type: ApplicationFiled: February 24, 2021Publication date: March 9, 2023Applicant: Hitachi Energy Switzerland AGInventors: Jan CZYZEWSKI, Krzysztof KASZA, Jedrzej BANASZCZYK, Andrzej RYBAK, Lukasz MATYSIAK

Publication number: 20230041971Abstract: The present disclosure relates to a condenser bushing including a condenser core and electrically conductive field-grading layers, which are embedded in insulating material of the condenser core and arranged around a central channel for conductor extending along an axis defining an axial direction, while an electric connection is provided to at least one of the field-grading layers, wherein pairs of neighbouring field-grading layers with the insulation material between them form sections of the condenser core of axial lengths L1 through Ln and with capacitances C1 through Cn, characterized in that a shape of at least one of the field-grading layers deviates from cylindricality in order to reduce non-uniformity of electric field stress of the condenser bushing compared to a corresponding condenser bushing with the cylindrical field-grading layers forming sections of the axial lengths L1 through Ln and with capacitances C1 through Cn.Type: ApplicationFiled: December 22, 2019Publication date: February 9, 2023Inventors: Jan Czyzewski, Jedrzej Banaszczyk, Darren Tremelling, Andrzej Rybak, Krzysztof Kasza, Lukasz Matysiak, Elio Perigo

Publication number: 20220324025Abstract: A system and method for forming electrical devices via additive manufacturing processes that utilize starting materials that are in a solid state at least prior to, as well as after, the formation of the electrical device. A first solid starting material can be configured to form one or more insulator layers of the electrical device, while another solid starting material can be applied to form one or more electrically conductive layers. The starting materials canbe applied layer-by-layer during formation of the electrical device such that the electrically conductive layers can become automatically embedded within the insulating layers, and vice versa. The additive manufacturing process(es) utilized to form the electrically conductive layers from solid starting materials can be different than the additive manufacturing process(es) utilized to form the insulator layers.Type: ApplicationFiled: April 30, 2020Publication date: October 13, 2022Inventors: Elio Perigo, Jonah Kadoko, Daniel Pierce Armstrong, Matthew Hetrich, Cherif Ghoul, Krzysztof Kasza, Lukasz Matysiak

Patent number: 11179768Abstract: A method of making sand casting moulds with a protective coating for a multiple process of reactive moulding of insulation components and products made by filling up a mould cavity with polymer materials, including composites, based particularly on epoxy resins or composites based on cellulose materials, the method wherein the process of infiltration of the mould structure is performed chemically by soaking through the raw mould structure with chemosetting or thermosetting material. The application of a protective layer on external surfaces of a sand casting mould is done by means of any spraying, immersion or deposition method, whereas material with anti-adhesive properties is used for the protective coating in the form of organic chemosetting, thermosetting, light-curing material or in the form of inorganic material, including metal.Type: GrantFiled: November 23, 2020Date of Patent: November 23, 2021Assignee: ABB sp. z o.oInventors: Robert Sekula, Grzegorz Kmita, Andrzej Rybak, Dariusz Bednarowski, Lukasz Matysiak, Radek Javora
