Abstract
Pneumatic disconnector, characterized in that it comprises a main contact and an auxiliary contact, both fixed on a hollow insulating column and connectable with one of the conductors of the circuit to be controlled, a main blade and an auxiliary blade articulated on a second insulating column and connectable in common with the other conductor of said circuit, respectively engageable with said contacts, the contact of said auxiliary blade being formed by a conical finger that fits in an equally conical and hollow contact, a device generating compressed air, connected to the gap of said contact fixed auxiliary for insufflating a current of air against the mobile auxiliary contact from the moment of the final rupture, means for actuating the compressed air generator and the main blade and elastic means connecting said main blade with the auxiliary blade for actuating it when the circuit of the main one is already open.
