Abstract (en)

A spring-operated energy accumulation control for medium and high-voltage circuit breakers. A first shaft (30) carrying a partially toothed ratchet wheel (31) that can rotate about its longitudinal axis and a second shaft (32) having its axis parallel to and eccentric with respect to the axis of the first shaft (30) and carrying the first end of a crank (33) that rotates around the second shaft axis, the said toothed wheel (31) is associated with a ratchet device (34) and carries a dragging means (38) and a blocking means (39) to bring it to a halt against a closing release device (44); the toothed wheel carries also means (40) for connecting the free end of a closing spring (41) and the said crank (33) carries an opening release device (45) at its second end which is linked to the first end of a manoeuvering bar (46) that in association with the lever mechanisms (47, 48, 49, 51, 52), the transmission shaft (50) and the opening spring (53) cause the closing and opening of a circuit breaker pole (54). <IMAGE>
