摘要： The invention relates to a drive system (20) for a circuit breaker. The drive system comprises an electromagnetic actuator (10) having a first coil (14), a second coil (15), an armature (12) arranged to be movable between a first and a second end position by means of the coils (14, 15), and permanent magnets (13) arranged to keep said armature (12) locked at said first and second end positions. In accordance with the invention both coils (14, 15) are energized simultaneously for effectuating the movement of the armature (12) between the two end positions, one for neutralizing the permanent magnet and one for attracting the armature. This is in contrast to prior art, wherein the coils are energized one at a time; one coil for moving the armature to one of the end positions and the other coil for moving the armature to the opposite end position. The energizing of neutralising coil is initiated before the energizing of the attracting coil.

The drive system comprises an electromagnetic actuator (10) having a first coil (14), a second coil (15), and an armature (12) arranged to be movable between a first and a second end position by means of the coils (14, 15). In accordance with the invention the coils (14, 15) are arranged in an anti-series connection, and both coils (14, 15) are energized simultaneously for effectuating the movement of the armature (12) between the two end positions. This is in contrast to the prior art, wherein the coils are energized one at a time; one coil for moving the armature to one of the end positions and the other coil for moving the armature to the opposite end position.
