Abstract

Patente de Invenção: <B>''DISJUNTOR COM RESISTêNCIA DE FECHAMENTO''<D>. O disjuntor compreende os primeiros contatos de arco (8) e permanente (9) montados fixos em um envoltório (1), segundos contatos de arco (11) e permanente (12) montados móveis no envoltório segundo uma certa direção longitudinal (3) e destinados a cooperar com os primeiros contatos, assim como um sistema de inserção de uma resistência de fechamento (4), os segundos contatos fazendo parte de um equipamento que apresenta um bocal de sopro (13). O sistema de inserção da resistência compreende um bloco semimóvel (14) que é disposto para ser deslocado, quando de uma operação de fechamento, pelo bocal de sopro, segundo a direção longitudinal. Esse bloco (14) apresenta um terceiro contato de arco (15) destinado a cooperar com um quarto contato de arco (16) fixo ligado ao primeiro contato permanente fixo. Por deslocamento desse bloco, o terceiro e o quarto contatos de arco (15, 16) são aproximados um do outro para curto-circuitar a resistência de fehamento, enquanto que o primeiro e o segundo contatos de arco (8, 11) são conectados um ao outro e que o primeiro e o segundo contatos permanentes (9, 12) são separados um do outro. Figura a ser publicada: figura 1. em posição de abertura completa.
