Abstract

VARIADOR DE DERIVAÇçO FORA DE CIRCUITO COM MECANISMO DE ATUAÇçO PARA TRANSFORMADORES ELÉTRICOS. Um variador de derivação fora de circuito (10, 20) com mecanismo de atuação para transformadores elétricos do tipo que compreende uma estrutura que inclui no mínimo duas barras alongadas (11) às quais uma série de contatos fixos do tipo prisioneiro (12) são integralmente conectados, arranjados ortogonalmente em série, e um conjunto de contatos de blocos de atrito móveis (14) que deslizam sobre os contato os fixos (12) graças à atuação de um parafuso sem-fim (23); uma rosca da porca é ajustada ou feita na parte extrema de um tubo isolante (27) coaxial com e fora do parafuso sem-fim (23) de modo que o conjunto de contatos móveis (14) é fixado por meio de um adaptador conformado (28) na parte extrema do tubo isolante (27) oposto à rosca da porca. Desta maneira a rosca da porca está em uma posição diferente daquela do conjunto de contatos móveis (14) em relação ao comprimento global do variador de derivação (10, 20) permitindo a utilização de contatos móveis (14) não restringidos pelas dimensões do tubo (27) e/ou parafuso sem-fim (23).
