Abstract
APARELHO PARA A REDUÇÃO DE UM COMPONENTE DE FLUXO MAGNÉTICO UNIDIRECTIONAL NO NÚCLEO DE UM TRANSFORMADOR. A presente invenção refere-se a um aparelho para a redução de um componente de fluxo magnético unidirecional no núcleo de um transformador, em particular, a um transformador trifásico que compreende uma pluralidade de enrolamentos de compensação (K1, K2, K3), os quais estão mageticamente acoplados ao núcleo do transformador. O dito aparelho é caracterizado pelo fato de que uma fonte de corrente controlável (S), para introduzir corrente nos enrolamentos de compensação (K1, K2, K3), é provido e está eletricamente disposta em série com os enrolamentos de compensação (K1, K2, K3) e de maneira específica, com o ponto neutro (P1) dos mesmos, o qual é formado pelas entradas dos enrolamentos de compensação (K1, K2, K3); e um transformador neutro de ligação à terra (H) é provido e está eletricamente conectado às saídas dos enrolamentos de compensação (K1, K2, K3); e a fonte de corrente (S) eletricamente conecta o ponto neutro (P1) dos enrolamentos de compensação (K1, K2, K3) ao ponto neutro (P2) do transformador neutro de ligação à terra (H).
