Abstract

L’invention consiste en un disjoncteur sectionneur, doté d’une fonction sectionneur comprenant un équipage mobile unique (11) assurant l’isolation et le passage du courant dans un fluide isolant grâce à une électrode de transition (9) qui court-circuite ou insère transitoirement une ampoule à coupure dans le vide (5) assurant la coupure ou l’enclenchement des courants. Les phases de commutation avec l’électrode (9) sont réalisés à iso-potentiel et sans énergie d’arc dans le fluide d’isolement grâce à la synchronisation des courbes espace-temps. La fonction d’isolation exclut l’ampoule à vide (5), et l’absence d’énergie d’arc dans le fluide isolant permet l’utilisation de l’air ou tout diélectrique à effet de serres réduit permettant de réaliser un disjoncteur-sectionneur sans SF6. Figure à publier pour l’abrégé: Figure 1.The invention consists of a disconnector circuit breaker, equipped with a disconnector function comprising a single movable unit (11) ensuring the insulation and the passage of the current in an insulating fluid thanks to a transition electrode (9) which short-circuits or transiently insert a vacuum interrupter bulb (5) to cut or engage the currents. The switching phases with the electrode (9) are carried out at iso-potential and without arc energy in the insulating fluid thanks to the synchronization of the space-time curves. The isolation function excludes the vacuum interrupter (5), and the absence of arcing energy in the insulating fluid allows the use of air or any reduced greenhouse effect dielectric allowing a circuit breaker to be made. -switch without SF6. Figure to be published for the abstract: Figure 1.
