Abstract

"CHAVE DE COMANDO ELéTRICO MINIATURIZADA, MODULAR". Um sistema de chave de comando elétrico compacto (10) empregando um número de componentes modulares (12, 14, 16 e 18) que se encaixam em sua interface combinando e são mantidos em isolação elétrica empregando isolação sólida (24, 70 e 82) de uma maneira que proteja substancialmente as porções condutoras elétricas do conjunto de contato com porções de voltagem mais baixa do sistema. O conjunto é primariamente constituído de cinco módulos. Um conector de carga de multifásico (16) tendo transformadores monitorando corrente integrais (80) para cada uma das respectivas fases; um transformador monitorando voltagem (18) o qual se encaixa no conector de carga (16) ; um atuador em linha e módulo interruptor a vácuo (14) providos para cada fase, que se encaixam no conector de carga (16) ; um interruptor a vácuo de três posições (12) conectado entre o módulo interruptor a vácuo (14) e a linha ou terra; e um módulo de controle eletrónico (84) que recebe entradas dos monitores de corrente e de voltagem (80, 18), relés do circuito, módulo interruptor a vácuo/atuador em linha (14), e sensores de temperatura (94), e provê saídas de controle programadas (96) para os atuadores em linha dos respectivos módulos de interruptor a vácuo (14).
