Abstract
An actuator for an electrical circuit interrupter utilizes a gas generating chemical charge which is carried in its own cylindrical operating chamber. These power units are stored in a magazine and are fed into an operating position by a transfer cylinder in the form of a rotary turret head having cylindrical cutouts for the power units. The operating position specifically is with a chamber juxtaposed opposite one of the two input ports of a duplex power cylinder which is connected to the operating linkages of the interrupter itself. After the power unit has operated to open the interrupter, it is ejected. The operating action is linked to a duplicate set of a storage magazine and transfer cylinder for the close direction so that while the interrupter is opening the duplicate close actuator portion is readied for instantaneous action. This provides for a fast reclosing duty cycle and multiple operations. Also, for high operating speeds and good reliability.
