摘要： Operating device for circuit breakers comprising an opening spring (1) and a closing spring(2), which preferably are both of the spirally wound flat rod or ribbon type and exert a torsional moment on each one of two shafts (3, 4) which are aligned. The shaft (3) of the opening spring (1) is connected to the circuit breaker via a lever (31). The closing spring (2) is mounted in a rotatable cylinder (21) and can be tensioned by rotating the cylinder (21) by means of a motor (22). The shaft (4) of the closing spring (2) is kept locked by a closing latch (8) which hooks up one of the arms of a star wheel (6). Closing of the circuit breaker and simultaneous tensioning of the opening spring (1) are performed by releasing the closing latch (8), whereby another one of the arms of the star wheel (6) engages a carrier latch (53) on the shaft (3) of the opening spring (1) and rotates this through an angle corresponding to one step on the star wheel (6). The carrier latch (53) is thereafter disengaged, whereby the shaft (3) of the opening spring (1) is hooked up on an opening latch (7) and the circuit breaker is ready for an opening operation. Immediately after the disengagement, the next arm of the star wheel (6) is hooked up on the closing latch (8), and the motor(22) is able to tension the closing spring (2) again.

摘要： The disclosure describes an air circuit breaker comprising, in combination, a rotational shaft (104) connected with a motor, a cam (113) which rotates in one direction through a ratchet (112) by a handle operation to accumulate pressure in an energy accumulating spring for contact closure, and engaging part (122) provided on the outer periphery of the rotational shaft, and a latch (120) which slides on and along the engaging part (122) of the rotational shaft (104) when the cam (113) is rotated by said handle operation, and which causes the cam (113) to rotate together with the rotational shaft (104) in engagement with the engaging part (122) of the rotational shaft when the rotational shaft is rotated in one and the same direction by the motor driving.

摘要： A device for controlling the rotation of shaft (12) through a preselected angle narrower than 360°. On the shaft there are mounted two fresh-wheels (10,11) one at least of which is actuatable by a lever (18) to which a predominantly rectilinear reciprocation is impressed. The connection between the lever (18) and the outer ring (17) of the free-wheel is embodied by a pin (25) integral with the ring and engaged by a slot (26) formed in the vicinity of the free end of the lever. The slope of the slot is such that in the thrust stroke of the lever it causes the lever end to approach a cylindrical race (29) of a disc (28) keyed to the shaft (12) beside the free wheel. In a determined position this race is cut away by a hollow space (30) so that when the lever end arrives in registry with the hollow space, it can be depressed and thus it prevents the drive transfer for the free-wheel ring.
