Abstract

"SISTEMAS E MéTODOS PARA DISTRIBUIR E BALANCEAR CARGAS ELéTRICAS". Aparelho e método para distribuir igualmente uma carga elétrica através de uma rede distribuidora de energia de n-fases. A corrente em cada fase de entrada (Ï1, Ï2 e Ï3) e em cada circuito de ramificação (1-5) é medida por um sensor de corrente (16, 18, 20, 42, 44, 46, 48 e 50). As saídas dos sensores de corrente são monitoradas por um processador (12). Associados a cada circuito de ramificação estão uma chave multipolar (22, 24, 26, 28 e 30) e um disjuntor convencional (32, 34, 36, 38, e 40). Cada chave (22, 24, 26, 28, e 30) é capaz de conectar seu correspondente circuito de ramificação (1-5) a qualquer fase de entrada (Ï1, Ï2, Ï3) e desconectar o circuito de ramificação (1-5) de todas as n-fases (Ï1, Ï2 e Ï3). O processador (12) periodicamente monitora a corrente fluindo através de cada fase de entrada e, baseado nas condições de carga do circuito de ramificação (1-5), reprograma as chaves (22, 24, 26) para manter as cargas dos circuitos de ramificação (1-5) igualmente distribuídas através de todas as três fases de entrada (Ï1, Ï2, Ï3).
