Definitions

  • the present invention relates to a protected reversing contactor using a multifunctional transmission system for controlling confirmation switches.
  • this type of reversing contactor usually comprises, inside a general housing, two identical contactor systems comprising two electromagnets, the armatures of which actuate two sets of respective phase switches, the inputs and outputs of which are respectively interconnected by means of two interconnection circuits.
  • a general protection circuit including a magnetic protection device using, for each phase switch, a magnetic trip device whose coil passes through the current passing through this switch, and a thermal protection device using bimetallic strips mounted in the phase circuits located downstream of the output interconnection circuit.
  • these two protection devices act in such a way as to cause a sudden opening of all the phase switches by means of a triggering mechanism at potential energy, following one of the two anomalies of the current previously. mentioned.
  • these reversing contactors are fitted with a mechanical interlocking system preventing the simultaneous closing of the phase switches which would lead, due to the interconnection circuits, to a general short circuit in the sector.
  • This protection is also supplemented, in certain cases, by the use of confirmation switches mounted in series in the supply circuit of the coils of the two electromagnets and which are actuated so as to cut off the supply circuit. of the electromagnet which is not excited, and thus prohibit any possibility of simultaneous excitation of the two electromagnets, for example following a wrong command.
  • the invention relates more particularly to a reversing contactor of this kind in which the actuation of the confirmation switches is effected by means of a multifunctional transmission system which can provide, in addition to the confirmation function, other safety functions having for effect of opening one or both confirmation switches.
  • this transmission system comprises two coaxial rotary shafts, arranged end to end and each provided: - a radial arm designed so that it can be rotated in one direction by the armature of a corresponding electromagnet; - A first finger or the like which extends radially projecting so as to cooperate with the confirmation switch of the other electromagnet, to open this confirmation switch, at the end of the rotation stroke in said direction; and - At least one second finger or the like which extends radially projecting so as to be able to be driven in said direction by an actuating member of a protection device.
  • the two electromagnets are arranged side by side and have two respective armatures movable in translation parallel to a determined direction.
  • the two rotary shafts are oriented perpendicular to said direction and are arranged opposite these two frames.
  • the confirmation switch associated with each of these electromagnets is located in a region adjacent to this electromagnet and to a corresponding rotary shaft, so that it can be actuated by a finger of this shaft.
  • one of the rotary shafts comprises an axial extension which overlaps the second rotary shaft as far as an area located beyond the arm carried by this second shaft.
  • the arm associated with the first rotary shaft is then carried by the free end of the above-mentioned extension.

  • This tripping mechanism 37 is more particularly designed so as to cause a sudden and simultaneous opening of switches 9 to 14, following the detection of one of the current anomalies, previously mentioned.
  • the triggering of this mechanism 37 also causes the simultaneous opening of two confirmation switches I1, I2 respectively placed in series with the coils 15, 16 of the electromagnets 4, 5 (dashed line connection 40).
