<p>1. A device for controlling a cycle comprising at least one disconnecting phase and at least one reconnecting phase of a circuit breaker which is provided with energy sources for enabling successively opening and closing operations, the energy of said sources being releasable by means of mechanisms each provided with an actuating coil (B1, B2), characterized in that each actuating coil (B1, B2) which is a percussion coil, is disposed in a circuit comprising a capacitor (C1, C2) and a controllable switch (I1, I2), the device comprising a circuit (T1-T3, TR1-TR3, D, DZ, C) for charging the capacitors (C1, C2) from the fault currents, and an overcurrent relay (R) which generates sequential signals for controlling the switches (I1, I2).</p> |
