| Zusammenfassung: | In a self-blast circuit breaker, the inner contact is equipped with a control body which extends into or against the outer contact, respectively. The control body forces the arc into an arcing zone in the form of a hollow cylinder. This achieves a more rapid pressure build up as a result of which the provision of the extinction chamber of the circuit breaker with extinguishing gas can be improved. The gas flow out of and into the arcing zone can be optimized by suitable shaping of the control body. |
