Abstract

"SISTEMA CONTATOR DE ISOLAçãO TENDO CONTATORES CONTROLADOS INDEPENDENTEMENTE". A presente invenção prove um aparelho de isolação elétrica tendo contatores controláveis independentemente (72A-C, 76A-C). O aparelho de isolação inclui um contator para cada fase (A-C) ou pólo de um dispositivo elétrico bem como cada fase (A-C) ou pólo de uma carga (78). O aparelho de isolação elétrica é projetado para prover isolação elétrica galvânica para e proteger um dispositivo de partida ou acionamento (70) tal que os contatores de lado de carga (72A-C) sejam alojados dentro de um único conjunto contator (66) e os contatores de lado de linha (76A-C) sejam alojados dentro de um único conjunto contator (68). Cada contator (72A-C, 76A-C) é construído tal que cada um inclua múltiplos conjuntos de contato (84A-C, 86A-C) que podem ser controlados independentemente para abrir e fechar. Além disso, os contatores (72A-C, 76A-C) dentro de um único conjunto contator (66, 68) ou alojamento podem ser controlados independentemente tal que os contatos (84A-C, 86A-C) de um contator (72A-C, 76A-C) podem ser abertos sem abrir os contatos (84A-C, 86A-C) dos outros contatores (72A-C, 76A-C) no conjunto contator (66-68). Adicionalmente, os contatores (72A-C, 76A-C) são construídos e controlados tal que um único contator de lado de linha (72A-C) e um único contator de lado de carga (76A-C) abram simultaneamente quando uma condição de circuito aberto for desejada.
