Abstract

L'invenzione si riferisce ad un dispositivo spegni-arco per interruttori, comprendente un vano di spegnimento (10) in cui ciascuna fase possiede un contatto fisso (11) e un contatto a coltello (12) articolato rispetto ad esso e che possiede una camera di spegnimento (33) nel cui organo di corpo (15) costituito da materiale isolante, sono disposte piastre di spegnimento (14), in relazione distanziata in modo da essere situate successivamente rispetto al percorso (P) del movimento di apertura del contatto a coltello (12). Il problema relativo a questo dispositivo è risultato essere dovuto al fatto che l'arco produce uno strato di fuliggine nella struttura di supporto della piastra di spegnimento costituita da materiale isolante, detto strato di fuliggine rendendo la struttura di supporto conduttrice tra le piastre di spegnimento. Di conseguenza, la capacità di interruzione dell'interruttore è notevolmente compromessa. Per eliminare questo problema, organi d'arresto (20, 21a, 21b, 31, 42) sono disposti tra le estremità delle piastre di spegnimento (14) sul lato del contatto a coltello (12) e dell'organo di corpo (15), detti mezzi d'arresto impedendo il contatto diretto con l'organo di corpo (15) almeno nei vani (22) fra le piastre di spegnimento (14).(Figura 1a)
