Abstract

întrerupator automat limitator de curent cu un sistem dublu de întrerupere a contactului electric, la care puntea de cuplare este legata elastic prin arcul de contactare la traversa de cuplare care este actionata printr-un dispozitiv de închidere, respectiv de deschidere si la care puntea de cuplare formeaza cu piesele componente ale piesei fixe de cuplare, bucle de curent cu actiune electrodinamica, care realizeaza singura sau în combinatie cu un dispozitiv electromagnetic cu bobina si armaturao ridicare a puntii de cuplare independent de dispozitivul de închidere, caracterizat prin aceea ca asupra puntii de cuplare (1) actioneaza un mecanism articulat format din doua pîrghii (5) articulate la puntea de cuplare (1) prin articulatia (7), î ntre pîrghii (5) actionînd arcul de contactare (9) fixat cu extremitatile sale de capetele pîrghiilor (5) opuse articulatiei (7), din doua placute (4) articulate, cu unul din capete, la pîrghii (5), iar cu celalalt capat prin intermediul unei articulatii (6) la traversa de cuplare (3), prin ridicarea puntii mobile (1)....
