Actuation and control device for electric switchgear

The present invention relates to an actuation and control device for opening/closing electric switching means, for example circuit breakers, reclosers, disconnectors and the like particularly for high- and medium-voltage transmission and/or distribution grids. The device according to the present invention is particularly adapted for use in high-voltage circuit breakers and is now described with reference to this application without limiting in any way its scope of application. A control and actuation device for opening and/or closing an electric switching device having at least one fixed contact and at least one movable contact, which includes an actuating device operatively connected to the movable contact and which supplies energy to perform opening/closure. The actuating device includes a motor with position control, which is operatively connected to the movable contact, and a power and control electronic unit which, following a tripping command, sends to the motor electrical signals for driving the motor so that the movable contact achieves a predefined rule of motion.
