Abstract

Patente de Invenção: <B>"DISPOSITIVO PARA A DETECçãO DE DESCARGAS PARCIAIS"<D>. O dispositivo de medição de descargas parciais (3) serve para a detecção de descargas parciais em uma instalação de alta-tensão com blindagem metálica isolada a gás e apresenta uma antena de fenda anular (6), disposta na superfície interna da blindagem metálica (1), um cabo de medição coaxial (7) levado a um aparelho de medição e um condutor de passagem adelgaçante (8) que une a antena de fenda anular (6) e o cabo coaxial de medição (7). A fenda anular (9) da antena é determinada por um eletrodo em forma de placa (10) o qual é colocado, eletricamente isolado, em uma abertura (5), prevista para uma peça adicional flangeada (4) da blindagem metálica (1). O condutor de passagem (8) apresenta um condutor interno que suporta o eletrodo (10) e que é conduzido ao condutor blindado (14) do cabo de medição (7) e um condutor externo conduzido à blindagem (15) do cabo de medição (7). A peça adicional flangeada (4) se adelgaça em forma de funil entre a abertura (5) e o flange (16), suportado por ela, e configura com sua superfície interna um primeiro setor do condutor externo do condutor de passagem (8). Um tal dispositivo de medição de descargas parciais (3) se destaca pela construção simples e compacta e é de fabricação favorável em termos de custo. A função de transmissão apresenta, na região UHF, importante para uma medição exata de descargas parciais, para freq³ências entre 300 MHz e 1,8 GHz, um setor configurado de maneira elevada e plana. A precisão de medição e a sensibilidade do dispositivo de medição de descargas parciais (3), por isso, são particularmente elevadas nesta faixa de freq³ência.
