Abstract

transformador. a presente invenção refere-se a um transformador (2) que contém uma parte elétrica ativa (4) organizada em um espaço de isolamento (14) e compreendendo um enrolamento primário (8), um enrolamento secundário (6) e um núcleo magnético (10), os ditos enrolamentos (6,8) sendo enrolados em torno do núcleo magnético (10) e sendo espaçados radialmente um do outro por um espaço de enrolamento (12) que compreende um líquido de isolamento (16;16a). o transformador (20 ainda compreende um bloco (18) que define um compartimento (20) fechado e separado do espaço de isolamento restante (22), o dito compartimento fechado (20) sendo, pelo menos, parcialmente organizado dentro do espaço de enrolamento (12). a invenção é caracterizada pelo fato de que o compartimento fechado (20) compreende um líquido de isolamento (16a) que seja diferente do líquido de isolamento (16b) compreendido no espaço de isolamento restante (22) do transformador (2), o líquido de isolamento (16a) compreendido no compartimento fechado (20) que tem uma força de campo de ruptura doelétrica mais elevada do que o líquido de isolamento (16a) compreendido no espaço de isolamento restante (22).
