Abstract

Abstract Translated from French L'invention est relative à un disjoncteur à arc tournant et à contacts principaux (20, 22). Parallèlement au circuit principal à L contacts principaux (20, 22) et à un circuit auxiliaire (52) contenant des contacts d'arc (54, 62) et la bobine de soufflage (64) est connecté un circuit de shuntage ayant des contacts de shuntage (28, 30), qui se séparent après la séparation des contacts principaux (20, 22) lors d'un mouvement d'ouverture du disjoncteur. L'arc de commutation est tiré sur les contacts de shuntage (28, 30) avant d'être transféré sur les contacts d'arc (54, 62) pour être mis en rotation par soufflage magnétique. The invention relates to a rotary arc circuit breaker with main contacts (20, 22). Parallel to the main circuit with L main contacts (20, 22) and to an auxiliary circuit (52) containing arcing contacts (54, 62) and the blow coil (64) is connected a shunt circuit having contacts shuntage (28, 30), which separate after separation of the main contacts (20, 22) during an opening movement of the circuit breaker. The switching arc is drawn on the shunt contacts (28, 30) before being transferred to the arcing contacts (54, 62) to be rotated by magnetic blowing.
