Abstract

SISTEMA DE ISOLAMENTO DE ALTA TENSÃO E MÉTODO DE FABRICAÇÃO DO MESMO. A presente invenção refere-se um sistema de isolamento de alta tensão para corrente contínua de alta tensão, compreendendo uma bucha (1) com um condutor (2), uma conexão (5) a um condutor de transformador (4), um eletrodo de blindagem condutivo (7) blindando a conexão (5) entre a bucha e o transformador e um sistema de isolamento circundante imerso em óleo de transformador. Uma barreira cilíndrica de isolamento sólido (8) encerra a conexão (5) entre o condutor de bucha (1) e o condutor de transformador (4). Adicionalmente, barreiras de isolamento sólido (12) são fixadas no lado externo do eletrodo de blindagem (7) e formando uma distância ao material de isolamento (3) da bucha e ao material de isolamento (6) do transformador, pelo que uma queda de tensão moderada sobre a barreira de isolamento sólido (12) é obtida. O sistema de isolamento é projetado para tensões CA/CC acima de 500 kV, preferivelmente 800 kV e até 1.000 kV. Um método de fabricação do sistema de isolamento está descrito.
