Abstract (en)
[origin: US2007163869A1] The invention relates to a device for controlling a circuit-breaker intended for opening and closing this electric power cut-off device comprising a mobile contact, this control device comprising a motor ( 3 ) with a rotary output shaft ( 12 ) and being connected to power supply means ( 4 - 9 ) and actuating means transforming the output displacement of the motor into a displacement of the contact, this device also comprising a mechanical spring arrangement involved in opening and closing the contact. According to the invention, the actuation means include a set of jointed elements providing the connection of the rotary shaft and of the ring, and, in the closed position of the contact, the set of jointed elements is near a dead centre position, a so-called open dead centre, the opening spring ( 15 ) being only able to drive it towards the open position upon moving past this dead centre during opening.
