Abstract

DISJUNTOR DE CORRENTE DE FALHA PARA DISTINTAS FREQUêNCIAS OPERACIONAIS. A presente invenção refere-se a disjuntores de corrente de falha que devem poder ser construídos menores e mais económicos. Para tanto está previsto disponibilizar no conversor de corrente de soma (3) um enrolamento secundário (2) com uma tomada intermediária (1) entre as tomadas extremas (4, 5). Com um dispositivo de comutação (6) o enrolamento secundário (2) pode ser ajustado á respectiva freqüência operacional tendo em vista a potência de disparo necessária. Assim, um disjuntor de corrente de falha com núcleo nanocristalino, altamente permeável, para o conversor de corrente de soma (3) pode ser fabricado a baixo custo e com pouco espaço de construção.
