Abstract

Patente de Invenção: <B>"DISJUNTOR DE MéDIA OU DE ALTA-TENSãO COMPORTANDO UMA CâMARA DE CORTE COM ESTABILIDADE DIELéTRICA MELHORADA"<D>. Disjuntor de média ou de alta-tensão, comportando uma câmara de corte contendo um gás dielétrico, na qual o deslocamento de um contato móvel (2) em relação a um contato fixo (3) para abrir o disjuntor dá origem a um arco elétrico que se estabelece rapidamente entre o contato móvel (2) e um eletrodo externo (6) que é ligado eletricamente ao contato fixo (3), e no qual uma bobina (7) montada em série com o eletrodo externo (6) é alimentada pelo arco elétrico para gerar um campo magnético que desloca o arco elétrico em relação ao gás dielétrico que está em repouso. Um eletrodo central (9) é ligado eletricamente ao contato móvel (2) e atravessa o eletrodo externo (6), para que o arco elétrico seja arrastado em deslocamento, sendo estabelecido entre os dois eletrodos (6, 9). O campo elétrico criado entre os dois eletrodos é sensivelmente uniforme, o que permite minimizar o risco de reatrair o arco elétrico.Invention Patent: <B> "MEDIUM OR HIGH VOLTAGE BREAKER BEHAVING A CUTTING CHAMBER WITH IMPROVED DIELECTRIC STABILITY" <D>. Medium or high voltage circuit breaker, comprising a cutting chamber containing a dielectric gas, in which the displacement of a mobile contact (2) in relation to a fixed contact (3) to open the circuit breaker gives rise to an electric arc that it is quickly established between the mobile contact (2) and an external electrode (6) which is electrically connected to the fixed contact (3), and in which a coil (7) mounted in series with the external electrode (6) is fed by the arc electric to generate a magnetic field that displaces the electric arc in relation to the dielectric gas that is at rest. A central electrode (9) is electrically connected to the mobile contact (2) and passes through the external electrode (6), so that the electric arc is dragged in displacement, being established between the two electrodes (6, 9). The electric field created between the two electrodes is substantially uniform, which allows to minimize the risk of retracting the electric arc.
