Abstract

Patente de Invenção: <B>"NúCLEO DE TRANSFORMADOR"<D>. Um núcleo de transformador compreende pelo menos uma perna e pelo menos uma parte de forquilha, onde a seção transversal da perna ou as pernas é regularmente de múltiplas bordas com mais que quatro bordas. O núcleo é feito de anéis enrolados a partir de tiras de largura constante, onde boas propriedades elétricas são obtidas. O transformador é também fácil de fabricar e impede desperdício de material.Invention Patent: <B> "TRANSFORMER CORE" <D>. A transformer core comprises at least one leg and at least one fork part, where the cross section of the leg or legs is regularly multiple-edged with more than four edges. The core is made of rings wound from strips of constant width, where good electrical properties are obtained. The transformer is also easy to manufacture and prevents waste of material.
