Definitions

  • the present invention relates to a modular circuit breaker provided with a first joystick having two stable opening positions respectively and closing, and associated with a remote control unit comprising a second controller, which is linked to the first controller by means rigid coupling, manual actuation of said first lever towards each other of its stable positions, being possible independently of the remote control unit.
  • the modular circuit breaker 10 shown so schematic, includes a first lever 11.
  • This circuit breaker is associated with a remote control unit 50 comprising a second joystick 12.
  • the two joysticks 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 a motor electric.
  • 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 arms 21b and 21c rectilinear, is designed to urge the rod 18 in the direction of the arrow A, i.e. in a position of coupling with the joystick 11.
  • the central winding 21a of this spring is arranged around a substantially cylindrical stud 22 crossed in its center by the axis 19 and integral with one of the ends of the link 18.
  • the arm 21b bears against the shaft of outlet 16 and the end of the arm 21c is in abutment against a pin 23 mounted on the rod 18.
  • the rod 18 is biased by the spring 21 bearing against a fixed stop 24.
  • the link In the vicinity of its end opposite the cylindrical stud 22, the link has a spout 25 provided with a notch 26 which, as will be seen later, is intended to cooperate with the stud 13 of the crank pin 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 displacements correspondents 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 joystick. We see that in this first stable position, the actuator of the remote control unit is disengaged, so that the first joystick can be operated 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 block receives control pulses which have the effect of activating the actuator and to rotate its output shaft 16 and the flywheel 20 carried by this shaft in the direction arrow B.
  • the axis 19, off-center and carried by the handwheel 20, moves in the direction arrow B on a circle 30 concentric with the output shaft 16.
  • the spring 21 arms and continues to press the link 18 in the direction indicated by the arrow A.
  • FIG. 5 illustrates a last phase of this closing sequence, consisting of disengage the engaging and disengaging mechanism, i.e. uncoupling the second joystick and the actuator of 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, constituted by the axis 19 continues to move on the circle 30, which generates a pivoting of this link in the direction of the arrow A 'which is opposite to the arrow A defined above.
  • This relative movement of the rod has the effect of moving the spout 25 and moving the notch 26 relative to the nipple 13.
  • first and second handles of the circuit breaker and the block respectively remote control are in their closed position and the mechanism clutch and disengageable is uncoupled. Consequently, for a user, it it is possible at any time to manually activate the first joystick.
  • Figures 6 to 8 illustrate the circuit breaker opening sequence, 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 located closed position and the link 18 being uncoupled.
  • the handwheel 20 turns in the direction of the arrow B 'which is opposite to that of arrow B defined above.
  • the pivot axis 19 of the rod 18 moves on the circle 30, which causes the spout 25 of said rod to pivot in the direction arrow A which corresponds to arrow A previously defined with reference to Figures 2 and 3. It should be noted that during this movement the link remains stressed by the spring 21 bearing against the outlet axis 16.
  • the joysticks After a change of state by manual operation, the joysticks are in a state of discrepancy with respect to the state of the remote control unit. Now in such a state of discrepancy, it may happen that an electrical order reaches the block remote control. It is therefore essential that this order can be executed without that the operation of the circuit breaker is disturbed.
  • FIG. 9 illustrates such a state of discrepancy in which the second lever 12 has was brought manually to its closed position F and where an order of closing is transmitted to the remote control unit.
  • the steering wheel 20 rotates in the direction of arrow B and therefore drives the axis 19 on the circle concentric 30 in the same direction as the direction of rotation of the flywheel 20.
  • the link 18 urged by the arm 21c of the spring 21 is in abutment against the body of the handle 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 handwheel 20 continues to turn in the direction of arrow B.
  • FIG. 10 shows another state of discrepancy in which the lever 12 has been manually brought to the open position O and where the remote control unit receives an opening order, this opening being already executed.
  • the purpose of this order is effect of driving the steering wheel 20 in the direction of arrow B ', which has the consequence bring the front edge 25a of the spout 25 of the rod 18 to bear against the body of the lever 12. Since this front edge 25a has an inclination in ramp shape and the handle 12 has a peripheral surface cylindrical, the spout 25 slides on this body then on the stud 13 until the moment when the notch 26 is in front of this stud. At this moment, the link 18 requested by the spring 21 pivots in the direction of the arrow A 'and the stud 13 engages in the notch 26.
  • the circuit breaker described above completely fulfills the functions assigned to it. It can be brought manually into one or into the other of its two stable states. Furthermore, it can also be brought into one either 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 triggered manually even if this order is inconsistent with the current state of the remote control unit.
