Abstract
APARELHO TRANSFORMADOR QUE AJUSTA AUTOMATICAMENTE A TENSãO DE FONTE DE ALIMENTAçãO TRIFáSICA. Um aparelho transformador que ajusta automaticamente a tensão de fonte de alimentação trifásica, compreendendo três terminais de entrada, três terminais de saída, um transformador trifásico de conexão Y, um grupo de chaves, e um circuito de comutação de chave. Os três terminais de entrada são respectivamente conectados a três linhas principais da fonte de alimentação trifásica, e os três terminais de saída são conectados a uma instalação de carga. O transformador trifásico de conexão Y compreende um núcleo, um circuito de enrolamento da fase R, um circuito de enrolamento da fase 5 e um circuito de enrolamento da fase T. No circuito de enrolamento da fase R, um enrolamento principal de fase R, um primeiro enrolamento auxiliar de fase R, uma primeira chave de fase R, um segundo enrolamento auxiliar de fase R, e um terceiro enrolamento auxiliar de fase R são conectados em série naquela ordem, entre o terminal de entrada Rin e um ponto neutro O, o terminal de saída Rout sendo conectado a outra extremidade do enrolamento principal de fase R. Uma segunda chave de fase R é conectada em paralelo com um circuito em série do primeiro enrolamento auxiliar de fase R e primeira chave de fase R. Uma terceira chave de fase R é conectada em paralelo com um circuito em série do primeiro enrolamento auxiliar de fase R, primeira chave de fase R, e segundo enrolamento auxiliar de fase R. Uma quarta chave de fase R é conectada em paralelo com um circuito em série do segundo enrolamento auxiliar de fase R, e terceiro enrolamento auxiliar de fase R. O circuito de comutação de chave controla as chaves com base nos níveis de tensão dos terminais de saida, para comutar entre primeiro a quarto modos de uma maneira alternativa.
