Abstract

Circuit breaker of the compressed gas type in the form of bursts including a fixed contact structure, said fixed contact structure being provided with a group of fixed main contact studs arranged with a cylindrical configuration and a fixed arcing contact centrally disposed, a movable contact structure which can cooperate with the fixed contact structure, a drive cylinder assembly supporting said movable contact structure and an insulating nozzle, said drive cylinder assembly located therein in an adjacent position at its forward end a relatively solid and annularly movable main contact which can be coupled in cooperation with said set of fixed main contact studs in the closed loop position in the closed circuit position of the circuit breaker, a relatively plunger element fixed, being able to said conjunt or actuating cylinder sliding on said relatively fixed plunger element during the opening operation, said solid mobile main contact being detachably coupled with respect to said fixed main contact studs prior to the time of further separation of the arcing contact. Moving relative to said fixed arcing contact, so that the arc occurs only between the fixed arcing contact and the moving arcing contact within said nozzle, whereby the limbs extending forward of the fixed main contact studs provided with rounded flared portions allow the circuit breaker to withstand a high electrical voltage.
