Abstract

DISPOSITIVO DE COMUTAÇÃO ELÉTRICA. A presente invenção refere-se a um dispositivo de comutação elétrica (1) que é enchido com um meio de isolamento dielétrico compreendendo um composto de organo-flúor, em particular, um flúor-éter, uma fluoroamina, uma fluorocetona ou uma fluoro-olefina e compreendendo pelo menos um arranjo de contato do arco elétrico com um primeiro contato do arco elétrico (4a) e um segundo contato do arco elétrico correspondente (4b). Pelo menos um primeiro volume intermediário (7) é provido a jusante do primeiro contato do arco elétrico (4a) e/ou pelo menos um segundo volume intermediário (8) é provido a jusante do segundo contato do arco elétrico (4b). Os volumes intermediários (7, 8) são usados para o aumento da pressão intermediária e da formação de jato de gás de exaustão para a transferência turbulenta de calor condutivo para paredes de metal (7b, 8b) do sistema de exaustão. Nas modalidades da invenção, o primeiro e/ou segundo volume intermediário (7, 8) é delimitado por pelo menos uma parede móvel (14a, 14b) disposta transversalmente em relação ao eixo geométrico longitudinal (z) e que é deslocável paralela ao mesmo por um dispositivo de acionamento (15, 16, 17).ELECTRICAL SWITCHING DEVICE. The present invention relates to an electrical switching device (1) which is filled with a dielectric insulating medium comprising an organo-fluorine compound, in particular a fluoro-ether, a fluoroamine, a fluoroketone or a fluoro-olefin. and comprising at least one arc contact arrangement with a first arc contact (4a) and a corresponding second arc contact (4b). At least one first intermediate volume (7) is provided downstream of the first electric arc contact (4a) and/or at least one second intermediate volume (8) is provided downstream of the second electric arc contact (4b). Intermediate volumes (7, 8) are used for intermediate pressure build-up and exhaust gas jet formation for turbulent transfer of conductive heat to metal walls (7b, 8b) of the exhaust system. In the embodiments of the invention, the first and/or second intermediate volume (7, 8) is delimited by at least one mobile wall (14a, 14b) arranged transversely to the longitudinal geometric axis (z) and which can be moved parallel to it by an actuating device (15, 16, 17).
