Abstract

Cette invention concerne un disjoncteur de basse tension avec possibilité de déclenchement rapide. Sa caractéristique principale est qu'au moins une des faces latérales du dispositif de contact fournit une bride ouverte qui a un trou traversant interne, et l'extrémité d'un axe tournant disposé sur la partie inférieure fournit un élément soumis à une contrainte. L'élément soumis à une contrainte reçoit le flux d'air de surpression s'échappant de la bride ouverte du dispositif de contact pour produire une force. La force est passée à l'élément de déclenchement par l'axe tournant et s'amplifie, frappe alors le verrou rapidement et fait une course. Dans une étape intermédiaire elle est déviée suite à la force produite antérieurement, la force qui est produite par la partie électromagnétique dans le système à énergie calorifique et électromagnétique, de sorte que le disjoncteur de basse tension puisse s'ouvrir rapidement et réduise le temps d'ouverture considérablement et améliore les possibilités de déclenchement.
