Abstract

Patente de Invenção: <B>"CAPTOR DE CORRENTE PARA APARELHOS ELéTRICOS"<D>. A presente invenção refere-se a um captor de corrente para aparelho elétrico que possui um circuito primário no qual circula uma corrente primária Ip, um circuito magnético e um circuito secundário. O circuito magnético compreende dois elementos idênticos 21, 22 em forma de U, realizados a partir de um perfilado estirado de seção circular de um material ferro-magnético, entre os quais se situam duas pastilhas entreferros 25, 26. O circuito secundário possui duas bobinas similares 32, 33, de forma cilíndrica, montadas em série e que circundam os entreferros, essas duas bobinas sendo realizadas de modo contínuo por uma só operação de bobinagem sem conexão elétrica entre as duas bobinas. O enrolamento 11 do circuito primário circunda uma das duas bobinas 32, 33. O captor é projetado para poder se adaptar a vários calibres de corrente primária Ip fazendo-se para isso variar o número Np de passagens do circuito primário entre as bobinas 32, 33, o número Ns de espiras do circuito secundário e a espessura E dos entreferros.
