Abstract:
1. A device for controlling the opening/closing operation of an electric switchgear in a power distribution network, said switchgear comprising: a movable contact and a fixed contact that can be separated/coupled during the opening/closing operation of said switchgear; an electromagnetic actuator having a law of motion which can be adjusted by a control unit, said electromagnetic actuator being operatively connected, by means of a kinematic chain, to said movable contact; wherein said control unit comprises a first processing means comprising: first storage means for memorizing predefined data related to the law of motion of said actuator; second storage means for memorizing predefined data related to the operating parameters of said electromagnetic actuator; said first processing means determining, based on said predefined data related to operating parameters of said electromagnetic actuator and on said predefined data related to the law of motion of the electromagnetic actuator itself, the actual law of motion of said movable contact operated by said actuator and generating a first control signal which is indicative of said actual law of motion.
