Abstract

1 / 1 resumo “sistema prã‰-fundente â€� um sistema para reduzir corrente de partida em um transformador de utilidade trifã¡sico apã³s energizaã§ã£o do transformador por uma voltagem trifã¡sica aplicada que utiliza um circuito prã©-fundente para estabelecer nã­veis de fluxo residuais nos segmentos de macho dos enrolamentos primã¡rios do transformador que estã£o prã³ximos dos nã­veis de fluxo prospectivos estabelecidos nos segmentos de macho pela voltagem aplicada. o circuito prã©-fundente inclui um capacitor prã©-fundente que, apã³s ser carregado a uma determinado nã­vel de voltagem, ã© descarregado serialmente atravã©s de dois dos enrolamentos primã¡rios para estabelecer os predeterminados nã­veis de fluxo nos segmentos de macho dos dois enrolamentos, e um nã­vel de fluxo reduzido no segmento de macho do enrolamento primã¡rio remanescente. o transformador ã© energizado no instante de voltagem de fase de pico referenciado positivamente para o terceiro enrolamento primã¡rio tal que o fluxo residual e prospectivo se aproxima de um nã­vel quase igual em todos os trãªs segmentos de macho e a corrente de partida ã© reduzida.
