Abstract

O objeto da invenção é uma cobertura para transformador de distribuição (1) enchido com um líquido dielétrico (4), equipado com dispositivo eletrônico (11) integrado com a cobertura, que é aplicada para transmissão e distribuição de energia elétrica. A cobertura se caracteriza por o dispositivo eletrônico (11) estar imerso no líquido dielétrico (4) que preenche um compartimento de resfriamento (5) fixado na cobertura (2); o compartimento de resfriamento (5) possui paredes laterais (7), uma parede de topo (8) e uma parede de fundo (6), tal parede de fundo (6) coincidindo com uma janela (2a) formada na cobertura (2); a parede de fundo (6) forma uma barreira térmica entre o interior do dispositivo de potência elétrica (1) e o interior do compartimento de resfriamento (5), com os dois interiores do compartimento de resfriamento (5) e do dispositivo de potência elétrica (1) ficando hermeticamente fechados juntos.
