Abstract

"APARELHO E SISTEMA DE APARELHO DE COMUTAçãO ELéTRICA", compreendendo um disjuntor (22) incluindo contatos separáveis (40) para movimento entre uma posição fechada e uma posição aberta. Um mecanismo de operação (46), que move os contatos separáveis (40) entre as posições fechada e aberta, possui um estado fechado e um estado aberto ou desarmado que corresponde à posição aberta. Um transformador de corrente (50) detecta a corrente elétrica que flui pelos contatos separáveis (40) como uma corrente detectada. Um mecanismo de desarme (48) emprega a corrente detectada para desarmar o mecanismo de operação (46) para a posição desarmada para mover os contatos separáveis (40) para a posição fechada. O mecanismo de desarme (48) inclui um microprocessador (56, <109>P) que gera funções de desarme de retardo a curto prazo e de perda à terra de corrente elétrica e tempo. O microprocessador (56, <109>P) dá entrada a um primeiro sinal de interbloqueio de um dispositivo de comutação elétrica a jusante (26) que gera o primeiro sinal de interbloqueio com um primeiro valor quando a corrente através do dispositivo a jusante (26) excede um valor predeterminado e com um segundo valor diferente. O microprocessador (56, <109>P) gera e dá saída a um segundo sinal de interbloqueio para um dispositivo de comutação elétrica (24) em resposta à primeira e segunda funções de desarme. O mecanismo de desarme (48) seletivamente desarma o mecanismo de operação (460 como uma função do primeiro sinal de interbloqueio, da primeira função de desarme e da segunda função de desarme.
