Abstract

"DISJUNTOR E APARELHO PARA DETECTAR FALHAS DE ARCO". Detector de falha de arco (29) do tipo que gera um sinal de disparo quando um acúmulo atenuado de tempos de pulsos produzidos cada vez que um arco é criado alcança um valor selecionado, inclui um condicionador de pulsos (105) que distingue entre disparos falsos induzidos por fenómenos tais como queima de lâmpada de tungstênio e ligar de uma lâmpada de tungstênio fria (101) controlada por um reostato (111). O condicionador de pulsos (105) inclui um diodo zener (107) que limita a amplitude dos pulsos aplicados ao integrador, e prolonga todos dos pulsos para reduzir a variação na duração de pulso. O último pode ser realizado por um detetor de picos (109) que prolonga pulsos que alcançam o limite zener para uma duração de pelo menos meio ciclo.
