Abstract

L'invention est relative à un disjoncteur à auto-soufflage de gaz diélectrique sous pression comprenant un dispositif de soufflage comportant un piston mobile de soufflage 18 et un cylindre mobile de soufflage 15 solidaire d'un contact mobile 11, entouré par une buse de soufflage du volume 17 de gaz comprimé par le cylindre et le piston lors de l'ouverture du disjoncteur. Le disjoncteur est caractérisé en ce qu'une bielle 34 articulée sur la tige de commande 13 du contact mobile 11 commande l'articulation 24 d'une genouillère 23 comportant d'un côté un levier 25 articulé sur un axe fixe 26 et de l'autre côté un levier 22 articulé sur un axe 21 solidaire du piston de soufflage 18 dont il commande le déplacement, de telle sorte que lors de la manoeuvre du disjoncteur entre sa position de fermeture et sa position d'ouverture, l'angle d'articulation formé par lesdits leviers soit successivement réduit jusqu'à une valeur minimale, accru jusqu'à une valeur maximale, puis réduit à nouveau. L'invention s'applique aux disjoncteurs à haute tension à auto-soufflage de gaz extincteur.
