Abstract

Patente de Invenção: <B>"TRANSFORMADOR IMERSO AUTOPROTEGIDO POR UM DISPOSITIVO QUE INCLUI UM DISJUNTOR E FUSìVEIS"<D>. O transformador elétrico 1 compreende um tanque 4 que contém um líquido ou gás dielétrico 5, e no qual estão imersos: um circuito primário e circuito secundário e um dispositivo de proteção conectado ao circuito primário e que compreende um disjuntor 15 controlado por um meio de desengate e um ou mais fusíveis 11. Os fusíveis estão dispostos entre uma bucha 6 do tanque e o disjuntor 15. Os fusíveis 11, o disjuntor 15 e o meio de desengate estão associados de um tal modo que sob as condições que correspondem a um curto-circuito nos terminais do circuito secundário, o meio de contato do disjuntor separa e interrompe a corrente sem que o fusível comece a fundir, e que existe um valor limite da intensidade de corrente que flui dentro do fusível, mais baixo do que a capacidade de abertura do pólo correspondente do disjuntor e acima do qual a fusão do fusível aconteceu antes que uma ordem de separação dos meios de contato dada pelo meio de desengate tenha sido capaz de causar a separação dos contatos.
