Abstract

"DISJUNTOR". Unidade de desarme eletrónico para um disjuntor (10) tendo dois sensores de corrente (16 e 17) por fase, em que o primeiro transformador de corrente de núcleo magnético (16) é projetado para monitorar corrente em regime normal e de sobrecorrente, e em que o segundo sensor de núcleo de baixa permeabilidade (17) é projetado para produzir um sinal de desarme de cancelamento no ou abaixo da tolerância à corrente intermitente nominal do disjuntor (10). Numa segunda concretização, a unidade de desarme eletrónico inclui apenas o sensor de núcleo de baixa permeabilidade (17) que possui saída insignificante em regime de corrente normal.
