Abstract

TRANSFORMADOR BI OU POLIFÁSICO. A presente invenção refere-se a um transformador bi ou polifásico, tendo uma culatra que tem uma travessa de pelo menos dois membros através de cujos membros uma bobina (17) é aplicada em cada caso, e tendo pelo menos um portador sobre o qual a travessa é fixada e que tem faces de apoio (14) para as bobinas. Pelo menos dois blocos de suporte (15, 16) para cada bobina são montados sobre cada superfície de apoio (14), os blocos de apoio sendo montados com elementos de compensação elásticos (35) sobre a face portadora do lado da bobina (19) e tendo sobre suas faces laterais (25,26) que se estendem perpendicularmente a superfície portadora (19) de pelos menos uma tira (27, 28) que se estende ao trajeto de perda gradativa de corrente e percorre o sentido longitudinal paralelo à face portadora do bloco de suporte.
