  • Two breaking chambers 36 of conventional type, arranged on either side of the operating rod 20, ensure the extinction of the two arcs coupled in series when the arc circuit is opened.
  • the movable arcing contacts consist of two sub-groups of movable arcing contact bridges 35, arranged on either side of the operating rod 20, so as to obtain the formation of two arcs in series in the plane of Figure 1, these two arcs being in parallel on two other arcs, themselves in series in a plane parallel to the previous one.
  • Four breaking chambers are then arranged so as to extinguish the four arcs.
  • the circuit breaker includes an unlocking device allowing the contacts to return to the closed position under the action of return springs 38 and 40 acting respectively on the main contact bridge 16 and on the arcing contact bridge 34.
  • the unlocking device intended to break the blocking of the hooking ring 28 by the half-moon 30, preferably uses the Thomson effect.
  • a closing coil 42 causes, when it is supplied by an electric discharge, for example by means of capacitors (not shown), the sudden repulsion of a closing disc 44 which is normally biased in position for approaching the coil by springs not shown in the figures.
  • the upward movement of the closing disc 44 causes the pivoting of a closing bar 46, causing the displacement of a closing rod 48.
  • the latter acts on the half-moon 30 so as to unlock the hooking ring 28.
  • a signaling element 50 is mounted on a fixed bearing 52, so as to be able to pivot under the action of torsion springs, from a closed position (fig. 1), where one of the ends of the element is biased downwards by the operating rod 20, to a position opening (fig. 2).
  • An electrical contact (not shown), arranged so as to be actuated by the operating rod 20 at the same time as the signaling element 50, also makes it possible to obtain an electrical signaling of the position of the circuit breaker.

  • a current sensor 70 is arranged in the lower housing around one of the current supply ranges.
  • a connector 72 mounted on the upper face of the intermediate housing, is intended to provide the electrical connections between the opening and closing coils and a trip unit, not shown, intended to control the circuit breaker.
  • the connector 72 also transmits the information from the current sensors 70 and the electrical signaling contacts.
  • the device according to the invention operates as follows: In the closed position of the circuit breaker (fig. 1), the main contact bridge 16 is biased by the springs 38 in the direction of the fixed main contacts, the arcing contact bridge 34 being biased by the springs 40 in the direction of the fixed arcing contacts 32. The current flows in areas 10, 12 and the main contact bridge 16.
  • the current sensor 70 supplies the trip device, not shown, with a current measurement.
  • the opening and closing coils 22 and 42 are not supplied and the opening and closing discs 26 and 44 are in the rest position near the corresponding coils.
  • the trigger Upon detection of a fault current or of the opening command, the trigger causes the opening coil 22 to feed and the upward repulsion of the assembly constituted by the opening disc 24 and the piston 26, driving the operating rod 20 upwards.
  • the latter being secured to the stirrup 56, itself secured to the cage 58 carrying the main contact bridge 16, the latter is pulled upwards, against the force of the return springs 38. It the main circuit is opened and the current is switched to the arc circuit.
  • the upper part of the cage 58 comes into contact with the lower part of the elements 35 of the arcing contact bridge 36 and drives the latter upwards against the force of the return springs 40 , also opening the arc circuit. There is then formation of arcs in series in the arc circuit, these arcs being quickly extinguished in the breaking chambers 36.
  • the hooking ring 28 releases the half-moon 30 which pivots and ensures the locking of the hooking ring, and consequently of the operating rod and of the contacts, in the open position.
  • the opening disc 24 then returns to the rest position, as shown in FIG. 2, while the piston 26 secured to the operating rod remains in the high position.
  • the closing of the circuit breaker is controlled by the supply of the closing coil 42, which pushes the closing disc upwards, causing the unlocking of the ring. attachment by rotating the half-moon 30 in the opposite direction by means of the bar 46 and the closing rod 48. Under the action of the return springs 38 and 40, the contact bridges, the cage, the bearing, the operating rod, the coupling ring and the piston are returned to the closed position shown in FIG. 1.
  • each of the poles has an independent opening mechanism, with its own opening coil and its independent half-moon locking mechanism. There is thus good security, the failure of one of the opening mechanisms does not prevent the opening of the other two poles.
  • the three-pole circuit breaker has a single closing system, simultaneously controlling the unlocking of the three poles.
  • the single closing coil 42 is preferably arranged in the central pole and controls, via the single closing disc 44, the closing bar common to the three poles, which actuates a closing rod 48 per pole, for simultaneous unlocking of the three half-moons 30.
  • the mass of the elements of the unlocking mechanism being low, it is thus possible to obtain a very rapid response time to an order to close the circuit breaker, by means of a single mechanism with Thomson effect.
  • the signaling elements 50 of the three poles are preferably coupled by means of a bar 74, so that the opening of the circuit breaker can only be signaled when the three poles are open. Indeed, as long as one of the poles is closed, the corresponding operating rod 20 pushes down the associated end of the corresponding signaling element 50, preventing the pivoting of the bar, and consequently, the pivoting of the elements other poles, even if these are in the open position.
  • the structure of the circuit breaker described above allows easy access to the different parts of the circuit breaker.
  • the elements of the control mechanism are easily accessible by simple removal of the cover 68.
  • the removal of the lower housing 14 carrying the fixed contact pads gives access to the contact sub-assembly 18, which forms a removable sub-assembly which can be checked or exchanged if necessary.
  • the interrupting chambers 36 can, for their part, be inspected or modified by sliding them in the intermediate housing 66 after removing the fixing screws 67.
