Definitions

  • the present invention relates to a modular circuit breaker provided with a first handle having two stable opening and closing positions, respectively, and associated with a remote control unit comprising a second handle, these two handles being linked by rigid coupling means.
  • the object of the present invention is to reduce the manual actuation force of a remote control circuit breaker.
  • the circuit breaker according to the invention characterized in that the remote control unit includes a clutch mechanism for coupling it to said second handle during the phases of passage of the first handle from one to the other of its positions. stable under the action of the remote control unit, and disengageable to disconnect it from this second lever outside of these phases, with a view to manual actuation of said first lever from one to the other of its stable positions.
  • said clutch and disengageable mechanism comprises a link articulated on a flywheel mounted on a rotary output shaft of an actuator, in particular an electric motor of the remote control unit, this link being provided with coupling means for the coupling to said second lever, a spring tending to urge this rod in a position of coupling with the lever, and stop means for opposing the action of the spring and preventing said coupling of this rod and this lever.
  • the coupling means of the link comprise a spout arranged to hang, in said coupling position, on a stud carried by a crank pin secured to the second lever.
  • the modular circuit breaker 10 shown schematically, has a first handle 11.
  • This circuit breaker is associated with a remote control unit 50 having a second handle 12.
  • the two handles are linked by rigid coupling means 51 which are for example constituted by a bar or by any other known element capable of ensuring the same function.
  • the remote control unit 50 comprises an output shaft 16 driven by an actuator, in particular an electric motor.
  • the clutch and disengageable mechanism is arranged to ensure a sequential coupling of the output shaft 16 and said second lever 12. This clutch and disengageable mechanism will be described in more detail below.
  • a spring 21 comprising a central winding 21a consisting of at least one circular or helical loop, and extended by two straight arms 21b and 21c, is designed to urge the link 18 in the direction of arrow A, that is to say say in a coupling position with the interlocking lever 11.
  • the central winding 21a of this spring is arranged around a substantially cylindrical stud 22 traversed in its center by the axis 19 and integral with one of the ends of the link 18.
  • the arm 21b bears against the output shaft 16 and the end of the arm 21c bears against a pin 23 mounted on the link 18.
  • the link 18 is urged by the spring 21 bearing against a fixed stop 24.
  • the rod In the vicinity of its end opposite to the cylindrical stud 22, the rod has a spout 25 provided with a notch 26 which, as will be seen later, is intended to cooperate with nipple 13 of m aneton 14 of the second lever 12. Since the link 18 is pressed against the stop 24, the stud 13 is released from the notch 26 and the mechanism is disengaged since the link 18, which in fact constitutes the connecting element between the remote control unit and the second controller is decoupled from this controller. It is obvious that the displacements of the second lever generate corresponding displacements of the first since the two levers are rigidly linked.
  • Figure 2 corresponds to the "open" state of the circuit breaker. This state corresponds to one of the two stable positions of its lever. It can be seen that in this first stable position, the actuator of the remote control unit is disengaged, so that the first lever can be actuated manually.
  • FIG. 3 corresponds to the start of a circuit breaker closing sequence, this closing being caused by the remote control unit.
  • This remote control unit receives control pulses which have the effect of engaging the actuator and rotating its output shaft 16 and the handwheel 20 carried by this shaft in the direction of arrow B.
  • the axis 19, off-center and carried by the steering wheel 20, moves in the direction of arrow B on a circle 30 concentric with the output shaft 16.
  • the spring 21 is armed and continues to urge the link 18 in the direction indicated by arrow A.
  • FIG. 4 The next phase of the circuit breaker closing sequence is illustrated in FIG. 4.
  • the flywheel 20 driven by the output shaft 16 of the actuator of the remote control unit, continues to rotate in the direction indicated. by arrow B.
  • the axis 19 on which the link 18 is articulated continues to move on the circle 30, which has the effect of driving the link, the spout 25 of which is attached to the stud 13 so that it drives the second lever 12 in the direction of the arrow C towards its second stable position F or closed position.
  • FIG. 5 illustrates a last phase of this closing sequence, consisting of disengaging the clutch and disengageable mechanism, that is to say uncoupling the second lever and the actuator from the remote control unit.
  • the axis 19 continues to move on the circle 30.
  • the link 18 was brought into abutment against the shaft 16. Because the flywheel 20 continues to rotate around this shaft the point of articulation of the link 18, formed by the axis 19 continues to move on the circle 30, which generates a pivoting of this link in the direction of arrow A 'which is opposite to arrow A defined above.
  • This relative movement of the link has the effect of displacing the spout 25 and displacing the notch 26 relative to the stud 13.
  • the first and second handles of the circuit breaker and of the remote control unit respectively are in their closed position and the mechanism clutch and disengageable is uncoupled. Consequently, for a user, it is possible at any time to manually actuate the first controller.
  • FIGS. 6 to 8 illustrate the opening sequence of the circuit breaker, this opening being controlled by the remote control unit.
  • the initial state is that which has been described with reference to FIG. 5, the second lever being in the closed position and the link 18 being uncoupled.
  • the handwheel 20 turns in the direction of arrow B 'which is opposite to that of arrow B defined above.
  • the pivot axis 19 of the link 18 moves on the circle 30, which causes the spout 25 of said link to pivot in the direction of the arrow A which corresponds to arrow A previously defined with reference to FIGS. 2 and 3.
  • the link remains stressed by the spring 21 bearing against the outlet axis 16. This pivoting has the effect of move the spout 25 until the notch 26 is placed around the stud 13 of the second lever.
  • the clutch and disengageable mechanism is engaged and the actuator of the remote control unit is rigidly coupled to the lever.
  • FIG. 7 The next phase of this opening sequence is illustrated in FIG. 7. During this phase the flywheel 20 continues to rotate in the direction indicated by the arrow B ′, which has the effect of displacing the rod 18 which remains coupled by means of the stud 13 to the lever 12 and passing the latter from its stable position F closed in its stable position O open.
  • This intermediate phase corresponds to the state represented by FIG. 3 of the closing sequence described above.
  • the last phase of this opening sequence is represented by FIG. 8 and consists in uncoupling the actuator from the remote control unit and the handle 12.
  • the link 18 is in abutment against the fixed stop 24 and as the flywheel 20 continues to rotate in the direction indicated by the arrow B ', the pivot point of the link 18, which is defined by the axis 19, continues to rotate in the same direction on the circle 30, which has the effect of rotating the spout 25 of said link in the direction defined by the arrow A 'and releasing the stud 13 from the notch 26.
  • This state strictly corresponds to the initial state of the closing sequence which has been described with reference to FIG. 2.
  • the joysticks After a change of state by manual operation, the joysticks are in a state of discrepancy with the state of the remote control unit. However, in such a state of discrepancy, it may happen that an electrical command reaches the remote control unit. It is therefore essential that this command can be executed without disturbing the operation of the circuit breaker.
  • FIG. 9 illustrates such a state of discrepancy in which the second lever 12 has been brought manually to its closed position F and where a close command is transmitted to the remote control unit.
  • the flywheel 20 rotates in the direction of arrow B and consequently drives the axis 19 on the concentric circle 30 in the same direction as the direction of rotation of the flywheel 20.
  • the rod 18 biased by the arm 21c of the spring 21 is in abutment against the body of the lever 12 which is in the form of a cylindrical drum.
  • the link slides on this drum until it comes into the position shown in FIG. 5, position in which the spout 25 rocks since the inner edge of the rod 18 is supported on the output shaft 16 of the actuator of the remote control unit and the flywheel 20 continues to rotate in the direction of arrow B.
  • FIG. 10 shows another state of discrepancy in which the lever 12 has been manually brought into the open position O and where the remote control unit receives an opening order, this opening being already carried out.
  • This order has the effect of driving the flywheel 20 in the direction of the arrow B ′, which has the effect of bringing the front edge 25a of the spout 25 of the rod 18 to bear against the body of the lever 12.
  • this front edge 25a has a ramp-shaped inclination and that the body of the lever 12 has a cylindrical peripheral surface
  • the spout 25 slides on this body and then on the stud 13 until the notch 26 presents itself in front of this nipple.
  • the circuit breaker described above fully fulfills the functions assigned to it. It can be brought manually into one or the other of its two stable states. Furthermore, it can also be brought into one or other of its stable states by remote control. Finally, an order transmitted by remote control is not disturbed by the fact that the circuit breaker has been tripped or tripped manually even if this order is inconsistent with the current state of the remote control unit.
