Abstract
Drive devices for switchgear interrupter units, having movable contact pieces that can be controlled by solenoid drives are described. The drives of the movable contact pieces being controllable by linear motor drives. The interrupter units are realized by vacuum circuit breakers, and the linear motor drives are realized by three-phase AC linear motors. Each of these can be influenced by a control unit that optimizes the switching operations and that is provided with a mains connection. The three-phase AC linear motors are composed of individual components that determine thrust and range of motion. The individual components together constitute the drive of the movable contact parts. The individual components are determined by the number of motor coils and/or by the number of parallel motor modules.
