Title (EN) GAS-INSULATED CIRCUIT BREAKER WITH NOMINAL CONTACT SHIELDING ARRANGEMENT
(FR) DISJONCTEUR À ISOLATION GAZEUSE À AGENCEMENT DE BLINDAGE DE CONTACT NOMINAL
Abstract:
(EN) A gas-insulated type circuit breaker (1) comprises a housing (4) defining a gas volume for a dielectric insulation gas; a first arcing contact member (10) and a second arcing contact member (20), wherein the first arcing contact member (10) and the second arcing contact member (20) are movable relative to each other along an axis (2); a first nominal contact member (40) and a second nominal contact member (60), wherein the first nominal contact member (40) and the second nominal contact member (60) are movable relative to each other along the axis (2); and a first nominal contact shielding arrangement (50) comprising an inner shield member (52) and an outer shield member (54), wherein the inner shield member (52) and the outer shield member (54) are arranged coaxially about the axis (2). The first nominal contact member (40) is arranged co-axially between the inner shield member (52) and the outer shield member (54), and is movable relative to the inner shield member (52) and to the outer shield member (54).
(FR) L'invention porte sur un disjoncteur (1) de type à isolation gazeuse comprenant un logement (4) délimitant un volume de gaz destiné à un gaz isolant diélectrique; un premier élément de contact de coupure (10) et un second élément de contact de coupure (20), le premier élément de contact de coupure (10) et le second élément de contact de coupure (20) étant mobiles l'un par rapport à l'autre le long d'un axe (2); un premier élément de contact nominal (40) et un second élément de contact nominal (60), le premier élément de contact nominal (40) et le second élément de contact nominal (60) étant mobiles l'un par rapport à l'autre le long de l'axe (2); et un premier agencement de blindage de contact nominal (50) comprenant un élément de blindage interne (52) et un élément de blindage externe (54), l'élément de blindage interne (52) et l'élément de blindage externe (54) étant disposés de façon coaxiale autour de l'axe (2). Le premier élément de contact nominal (40) est disposé de façon coaxiale entre l'élément de blindage interne (52) et l'élément de blindage externe (54) et il est mobile par rapport à l'élément de blindage interne (52) et par rapport à l'élément de blindage externe (54).
