Abstract

resumo patente de invenção: "equipamento elétrico com isolamento de gás". a presente invenção refere-se a um equipamento elétrico com isolamento de gás que inclui: um condutor de alta voltagem (3) para ser eletricamente carregado; um tanque hermeticamente selado (12) para ser preenchido com o gás de isolamento (15), um ou mais espaçadores de isolamento (11) para dividir o tanque hermeticamente selado (12) em compartimentos de gás e suportando o condutor de alta voltagem (3); e um dispositivo de liberação de pressão (2) equipado com uma porção de boca de canal de fluxo adaptada para permitir que o lado de dentro e o lado de fora do tanque hermeticamente selado (12) se comuniquem um com o outro de modo a liberar a pressão no tanque hermeticamente selado (12), que mantém o estado hermeticamente selado em uma condição simples onde a pressão no compartimento de gás (111) não excede a pressão de trabalho mas libera a pressão no tanque hermeticamente selado (12) em uma condição anormal onde a pressão no compartimento de gás (111) excede a pressão de trabalho.
