摘要： An actuation and control device for opening and/or closing high- and medium-voltage circuit breakers having at least one fixed contact and at least one moving contact, comprising actuation means which are operatively connected to the moving contact and supply the energy for performing the opening/closure movement, the particularity of which consists of the fact that the actuation means comprise a servomotor, an electronic control and power supply unit, and elements for transmitting motion, and that the actuation means and/or the coupling between the fixed contact and the moving contact are such as to achieve a desired speed of the moving contact at the instant in which it separates from the fixed contact.

摘要： The present invention relates to a control and actuation device for opening and/or closing electric switching means having at least one fixed contact and at least one movable contact, which comprises actuating means which are operatively connected to the movable contact and supply the energy to perform opening/closure. The particularity of the invention is the fact that the actuating means comprise 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.
