Abstract

The arc extinguishing device is suitable for use on DC switches. It has a blow-out coil switched in during the switches. It has a blow-out coil switched in during the switch-off process. The blow-out coil (14) is connected across two of the many break contacts (1-3). The arc extinguishing chamber (11) has flexible contacts (18, 19) for the blow-out coil. These flexible contacts contact the fixed contacts (9, 10). The extinguishing chamber has a permanent magnet (15) to produce the primary blow-out field. The advantage lies in making the arc extinguishing blow field dependent on the arc current.
