Abstract

EQUIPAMENTO ELéTRICO PARA UMA REDE DE DISTRIBUIçãO DE ELETRICIDADE. A presente invenção refere-se a um equipamento elétrico compreendendo elementos elétricos (2, 2A, 3, 4, 8) correspondendo com pelo menos uma fase (8) da rede de distribuição e alojado em um tanque (6). O equipamento é isolado por meio de um liquido dielétrico (5) em que os elementos são imersos. O equipamento compreende uma entrada (9) para cada fase (8) no tanque (6), e também um dispositivo de proteção (7), associado a pelo menos um detector de falha (10) e configurado de maneira que, no evento de detectar tal falha, um curto circuito será estabelecido nas fases (8). O dispositivo de proteção (7) está situado de maneira a estabelecer referido curto circuito em uma posição antes que qualquer sistema de proteção (4), controle (2, 2A) ou elemento transformador (3) do equipamento elétrico (1).
