Definitions

  • circuit breaker includes here in particular differential circuit breakers of the RCBO type (for “Residual Circuit Breaker with Over-current”) and miniature circuit breakers called MCB (for “Miniature Circuit Breaker”).
  • the system is, for example, fixed to the corresponding circuit breaker using a padlock and then blocks the passage of the circuit breaker handle so as to prevent manual or automatic operation of the circuit breaker.
  • FIG. 1 An example of locking system 10 for circuit breaker 12 according to a first embodiment is represented on the figures 1 to 4 .
  • the locking system 10 is adapted to be fixed on an upper part of the circuit breaker 12.
  • the circuit breaker 12 is here provided with at least two, here two, orifices 19 arranged between the position of the lever in the active position and the position of the lever in the inactive position along the longitudinal direction. More particularly, the orifices are delimited by the longitudinal flanges 18, here one orifice per longitudinal flange.
  • the circuit breaker 12 also has an upper face 19.
  • the longitudinal and transverse directions relative to the locking system 10 are defined as the directions previously defined relative to a circuit breaker in the frame of reference of the locking system 10 when it is placed on a circuit breaker.
  • the locking system 10 here comprises a base 20, an elastic biasing element 22 and a cover 24.
  • the base 20 When the locking system 10 is placed on the circuit breaker 12, the base 20 extends into the space freed by the removal of the front panel 15 in the upper portion of the circuit breaker 12.
  • the accessible face 30 is here adapted to extend in the continuity of the central portion of the facade 15 of the circuit breaker 12.
  • the first side 32 is adapted to lie against the circuit breaker 12.
  • the second portion 38 extends in the continuity of the accessible face 30 of the main body 26.
  • the second portion 38 is here a solid face, substantially rectangular.
  • the base 20 further comprises a pivot 46 and/or a guide element 48 and/or a ring 50.
  • Tab 52 extends away from backing 54 except for its bonded ends.
  • a padlock whose shackle is inserted into the opening 56 then has a limited size in the transverse direction Y, given the orientation of the opening 56.
  • the ring 50 extends to the free end of the support 54. More particularly, the free end of the support 54 partially forms the ring 50.
  • the elastic biasing element 22 extends here mainly along the longitudinal direction X.
  • the branches 60 extend from the central part in the direction of the central portion of the facade 15 when the locking system is in position.
  • each branch extends in the transverse direction to within 5°.
  • the branches 60 are asymmetrical with respect to the plane of symmetry.
  • the elastic biasing element 22 exerts a force to return the branches 60 to its resting shape, that is to say here separating the branches 60, here in the transverse direction Y.
  • the elastic biasing element 22 is movable relative to the base 20 between a so-called free position, shown on the figure 2 , and a so-called locking position, represented on the figure 3 and 4 .
  • the central portion of the resilient biasing member 22 extends proximal to the guide member 48.
  • the cover 24 is integral with the base 20, here at the level of the pivot 46.
  • the biasing element 22 In position on the circuit breaker, in the closed position of the cover 24, the biasing element 22 is arranged in the space between the circuit breaker 12 and the cover 24.
  • the elastic biasing element 22 is in the free position.
  • Circuit breaker 12 operates normally.
  • the force exerted on the branches 60 is then released.
  • the elastic biasing element 22 returns to its resting shape, so that the branches move apart and the end portions 62 fit into the orifices.
  • a padlock or a lock is then advantageously fixed so as to pass through the ring 50 and to maintain the locking system 10 in the locked configuration and to prevent the change of configuration of the locking system 10.
  • the circuit breaker 12 then operates normally again, the locking system 10 still being arranged on said circuit breaker 12.
  • the second embodiment differs in that the movement of the elastic biasing element 122 between the at least one free position and the locking position is achieved by rotation, more particularly by rotation around an axis of rotation s' extending substantially in the transverse direction Y.
  • the ring 150 has a vertex, the vertex being the point of the ring 150 furthest from the base 120.
  • the ring 150 extends locally in the transverse direction Y.
  • the ring has a local tangent at the top, the tangent extending in the transverse direction Y.
  • the central part of the elastic biasing element 122 is here able to enter into rotation around the ring 150, more particularly around the top of the ring 150.
  • the locking system comprises a part, other than a cover as described above, linked to the base, for example to the support, and movable relative to the base, so as to be inserted between the branches of the elastic biasing element.
