Abstract

NúCLEO DE TRANSFORMADOR COM ANTEPARO MAGNETICO. A presente invenção refere-se a um núcleo de transformador, que compreende um interior de núcleo, que consiste em um material magnetizável. Fluxos de dispersão magnéticos criam correntes parasitas nas regiões externas do núcleo, o que leva a perdas de potência e superaquecimento local. Os referidos fluxos de dispersão são canalizados e conduzidos para fora da região externa do interior do núcleo por um anteparo, que parcialmente circunda o interior do núcleo e consiste em pelo menos um material magnetizável em camadas. Isso permite que a formação de correntes parasitas no interior do núcleo seja significativamente reduzida e, desse modo, evita superaquecimento local do núcleo de transformador e perdas de potência.
