Definitions

  • the present invention relates to a circuit breaker comprising, in a housing and for each pole, a breaking structure comprising a cage having windows for the passage of a movable contact bridge associated with fixed contacts, said windows authorizing the movement of the bridge. contact under the effect of a mechanism for opening and closing the contacts, and in the event of electrodynamic repulsion, and a pusher subject to said mechanism and guided by said cage, this pusher urging the contact bridge against a contact pressure spring.
  • circuit breaker is described for example in European patent application 0 501 885 A1 filed in the name of TELEMECANIQUE, which represents a state of the art according to Art. 54 (3) EPC.
  • EPC electronic circuit breaker
  • the object of the invention is in particular to transfer to the contact bridge structure functions, such as functions for guiding the pusher and / or arc confinement, usually devolved to the circuit breaker housing.
  • a circuit breaker comprising, in a housing and for each pole, a breaking structure comprising a cage having windows for the passage of a movable contact bridge associated with fixed contacts, said windows authorizing the displacement of the contact bridge under the effect of a mechanism for opening and closing the contacts, and in the event of electrodynamic repulsion, and a pusher subject to said mechanism and guided by said cage, this pusher urging the contact bridge against a spring contact pressure, in which, according to the invention, said cage is fixed relative to the housing and comprises insulating side wings arranged so as to delimit a volume containing the cutting arcs.
  • the cut-out structure can be produced as a telescopic sub-assembly that is easy to install in the circuit breaker housing.
  • the pusher preferably comprises at least one light dimensioned to allow the introduction of the contact bridge and an angular movement of the bridge relative to the pusher, the movement being therefore made possible although the pusher is guided in translation in the fixed cage .
  • the cut-off pre-chambers formed by the insulating side wings are embraced by the ends of fins of arc extinguishing structure.
  • the circuit breaker illustrated in FIG. 1 comprises a housing made of insulating material 10 of which only the base part is represented and, in this housing, several polar current paths each provided with a breaking structure S with separable contacts.
  • each pole path comprises two fixed contacts 11, 12 arranged on fixed contact pieces 13, 14 connected to terminals not indicated.
  • It comprises, on the other hand, two movable contacts 15, 16 associated respectively with the fixed contacts 11, 12 and arranged on an electrically conductive and movable bridge 17 to constitute a double-pole polar switch.
  • a bottom wall 18 and interpolar partitions 19 are the elements of the housing cooperating with the breaking structure.
  • the movable contact bridge 17 is biased by a mechanism (not shown) for opening and closing the contacts, this by means of a pusher 20 guided according to the invention in a fixed cage 21.
  • the cage 21 is made of insulating material and comprises a bottom wall 22, side walls 23 perpendicular to the interpolar partitions 19 and provided with windows 24 and solid side walls 25 parallel to the partitions 19.
  • the bottom wall 22 of the cage is placed on the bottom 18 of the housing 10 .
  • FIG. 2 is illustrated in more detail a first embodiment of the breaking structure S.
  • the windows 24 of the side walls 23 of the fixed cage are dimensioned to allow the displacement of the contact bridge, in particular under the effect of the opening-closing mechanism in the event of repulsion electrodynamics.
  • the windows 24 determine an upper stop 26 for the contact bridge 17.
  • a helical spring 28 of contact pressure is housed between the bottom wall 22 of the cage and the contact bridge 17 in a central recess 29 of the cage 21 which also serves as a housing and guide in translation for the pusher 20. The latter is thus guided against the internal faces of the side walls 23, 25 of the cage by respective walls 30, 31.
  • the walls 30 of the pusher are indented by lights 32 dimensioned to allow, on the one hand, the introduction of the bridge into the pusher, on the other hand, an angular movement of the bridge relative to the pusher.
  • a central orifice 33 allowing the passage of the spring 28.
  • the bottom wall 22 of the fixed cage has a re-entrant part 34 serving for the passage of a folded flat piece 35 of arc deflection which connects them the respective interrupting chambers 36, 37.
  • the fixed cage 21 of the cut-off structure S comprises insulating wings 38 parallel to the interpolar partitions 19 and extending longitudinally over a distance slightly greater than the length of the bridge 17 and of sufficient height to create a volume containing the cutting arcs.
  • Finned assemblies 39 which have the function of dividing and driving out the arcs, comprise a certain number of fins 40 in the general shape of a U open on the contact side. The open area of the U embraces, by its wings 41, the insulating wings 38 of the fixed cage.
  • the bottom wall 22 of the fixed cage is advantageously projecting to be housed in a central cavity 42 corresponding to an external projection of the bottom 18 of the housing 10, in order to reduce the overall height of the circuit breaker.
  • Pins 43 are provided on the deck 17 to cooperate with corresponding shapes of the walls 30 of the pusher 20, in order to keep the bridge centered with respect to the pusher.
  • the wings 38 of the cutting structure define, with a corresponding veil 44 which extends the bottom wall 22 of the cage, cutting pre-chambers 45, 46 housed in the chambers 36, 37.
  • the fixed cage 21 is advantageously in a material separate from that of the base of the housing since the cage supports most of the cutting stresses.
  • the structure described with regard to a circuit breaker obviously applies to different protective switch devices, in particular to contactors-circuit breakers.
