<p>"ELECTRICAL CIRCUIT BREAKER WITH ARC EXTINGUISHING COM PRESSED FLUID" The present invention relates to an electrical cir cuit breaker with arc extinguishing compressed fluid, in which the compression of the extinguishing fluid is caused in a mixed way, by the pneumatic action of a com pressing piston solid with the movable contacts of the circuit breaker and by pressure self-generation, follow ing the action of the electrical arc, which decomposes and heats the fluid. This compression in a mixed form takes place within a chamber provided within a movable body assembled on the stationary contact of the circuit breaker and suitable to follow, under the action of elastic means, along a certain path, the opening stroke of the movable contact, which bear a blasting nozzle, which during said stroke path connects a zone of compression of the fluid under the action of the piston with said chamber of the movable body, and which, after the detachment from the movable body because of its stopping, allows the escape of blasts of compresses fluid, both from said chamber and from the compression zone, directed against the arc to the purpose of extin guishing it.</p> |
