Abstract

Device for actuating opening/closing commands for a high-voltage circuit breaker, the special feature of which consists in the fact that it comprises, for each pole of the circuit breaker, pulse generating means designed to generate a pulse after receiving a command for opening/closing of a circuit breaker and oscillator means designed to convert the pulse into a train of pulses for driving transformer means which are arranged in series with the oscillator means and the output signals of which cause opening or closing of one or more circuit switching means so as to allow the supplying of voltage to a coil actuating the commands for opening/closing the respective pole associated therewith.
