Abstract (en)

Control device for the opening/closing of electrical switchgear such as circuit-breakers, isolators, reclosers and the like, in an electricity distribution and/or transmission network characterised by the fact that it comprises: an actuator with adjustable law of motion; a processing and control unit that receives an operating command and sends a control signal to the actuator that is processed in relation to: a predetermined nominal behaviour; direct or indirect information on the position, velocity, acceleration of the mobile part of said switchgear; information on the change, in relation to the nominal behaviour, of the entire actuator-kinematic chain-switchgear controlled system; in such a way as to realise the desired law of motion of said mobile part. <IMAGE>
