Abstract

ENROLAMENTO ELÉTRICO, TRANSFORMADOR SECO COM ESSE ENROLAMENTO ELÉTRICO E PROCESSO PARA PRODUÇÃO DE UM ENROLAMENTO ELÉTRICO.A presente invenção refere-se a um enrolamento elétrico (10, 20) para um transformador seco (1), que permite a construção de um transformador seco compacto, mesmo em classes de tensão mais altas. Para esse fim, o enrolamento elétrico (10, 20) apresenta uma pluralidade de espiras de um condutor de enrolamento (11), enroladas para uma bobina (15). A bobina (15) está embutida em um corpo de isolamento sólido (12). De acordo com a invenção, está previsto que sobre a superfície (13) do corpo de isolamento (12) está aplicado um revestimento (14) de um material eletricamente condutor.ELECTRICAL WINDING, DRY TRANSFORMER WITH THAT ELECTRIC WINDING AND PROCESS FOR PRODUCING AN ELECTRIC WINDING. The present invention refers to an electrical winding (10, 20) for a dry transformer (1), which allows the construction of a compact dry transformer , even in higher voltage classes. For that purpose, the electrical winding (10, 20) has a plurality of turns of a winding conductor (11), wound onto a coil (15). The coil (15) is embedded in a solid insulating body (12). According to the invention, provision is made for a coating (14) of an electrically conductive material to be applied to the surface (13) of the insulating body (12).
