Definitions

  • the invention relates to a contactor device comprising an electromagnet for controlling a multiplicity of power contacts and means for automatic opening of these contacts which react upon the appearance of overloads in a power circuit, of a share to separate, independently of the electromagnet, and using a magnetizable part and an overload coil placed in series in this circuit, a movable power contact (belonging to this circuit) of a fixed contact with which it cooperates, and to open on the other hand a control switch placed in series with the coil of the electromagnet, this switch being able to be opened by a local control member which is able to close the contacts.
  • the invention therefore proposes to provide a contactor device in which we have remedied the drawbacks mentioned above, and in particular to inform the user about the state of the device, to reduce the volume, to guarantee a effective opening of the contacts in a very short time and to ensure operating stability when shocks or movements are developed by the electromagnet.
  • this result is achieved thanks to the fact that the movable contact of the power contact, which is subjected to the action of a spring tending to close it, is capable of being separated from the fixed contact by means of a contact-holder or push-button which is actuated either by a movement coming from the armature of the electromagnet, or by a lever struck by said magnetizable part when the latter is excited by the overload coil, this lever cooperating with a first eclipsable latch which is separated from the electromagnet, said first latch being able to hold this lever in a latching position for which the movable contact is open, and having an end causing the release of a first triggering mechanism abrupt, this mechanism comprising a movable transmission part which is subjected to a return spring tending to bring it from a first stable position F visible where the control switch is closed towards a second stable position 0 visible where c and switch is kept open.
  • the device illustrated in fig. 1 comprises in a housing 1 an electromagnet 2 having a yoke 3, an excitation coil 4 and a movable frame 5 subjected to the action of a return spring 6 to establish its rest position.
  • the armature 5 is associated with a control lever 11 capable of actuating, by lifting it, a pusher 12 of a power contact 13 further comprising a movable contact 14 subjected to the action of a fixed spring 15 which tends to apply it to two fixed contacts 16,17.
  • the pusher 12 which carries the movable contact 14 is guided by surfaces 1
  • This contact 13 is mounted in series in a power circuit 18 placed between the supply and connection terminals 19, 20.
  • This circuit 18, which also includes a overload coil 21, represents one of the power circuits of the device which will comprise at least as many as the number of phases of the network which supplies it, and the energy of which must be used by a load not shown; when several power circuits are implemented, a single lever 11 therefore actuates several pushers such as 12.
  • the overload coil 21 cooperates with a magnetizable striker 22 which is possibly kept in the rest position by a weak spring 23, and which will be suddenly attracted if a very strong current important, for example a short-circuit current, crosses circuit 18.
  • the striker 22 strikes a lever 24 retained by a spring 25, a first arm 24 'of which is placed opposite the pusher 12 so that the percussion is retransmitted to the latter, and that the movable contact 14 is opened very quickly by push-button 12.
  • This lock has an end 31 and a portion 32, the latter being capable of lifting, during the movement of the lock, an arm 33 belonging to an oscillating control lever 34 and held in the rest position against a stop 35 by a spring 36 .
  • This lever 34 has, on the one hand, an end 38, for example insulating, which operates the opening of the control switch 8 when the lever is moved from its rest position, and has, on the other hand, a hooking tooth 37 able to cooperate with a holding surface 39, for example an inclined ramp, belonging to a transmission part 40; this transmission part also has a bearing surface 41 and cooperates with a local control member shown diagrammatically at 42.
  • a thrust surface 43 for example carried by an inclined ramp, is placed on the transmission part 40 in a region 66 of the latter; this transmission part is also subjected to a compression spring 44 which tends to push it in the direction S towards a fixed stop 45 carried, for example, by the housing 1.
  • the transmission part 40 or even the control member locale 42 carry an index 71 moving opposite a scale 72 carrying marks such as F and 0.
  • the reference 71 When the device is put into service, the reference 71 is opposite position F and the transmission part 40 is retained in a corresponding stable position by the tooth 37 of the lever 34 at rest, so that, the circuit 7 being closed , any control signal applied between 9 and 10 will cause the excitation of the electromagnet 2, the attraction of the armature 5, the tension of the spring 6, the tilting of the lever 11 and the closing of the power contact 13 , the latter being produced by the pressure spring 15.
  • the end 31, or the ends such as 31 when the apparatus comprises several power circuits are placed opposite the region 66 of the part. 40 so as to be able to cooperate, when the time comes, with the ramp 43.
  • a first intermediate pusher could be placed between ends such as 31 and the ramp 43
  • a second intermediate pusher could be placed between portions such as 32 and the arm 33 of the lever 34.
  • the coil 21 instantly attracts the striker 22 which switches the lever 24; this raises the pusher 12 which opens the contact 13, and simultaneously releases the latch 29 which moves upwards in the figure by bringing opposite the arm 26 a bearing surface 28 which prevents the lever 24 from returning to its position rest, so that the movable contact 14, which is moved very quickly, is kept in the open position by its pusher 12 and by the lever 24 independently of the lever 11 associated with the armature of the electromagnet.
  • the bolt 29 brings, on the one hand, the end 31 towards the ramp 43 (in dotted lines) and, on the other hand, causes the arm 33 of the lever 34 to be raised by the portion 32.
  • the opening of the switch 8 causes the electromagnet 2 to de-energize, the armature 5 to fall back and the lever 11 to tilt, which therefore approaches the pusher 12, held in the high position from its percussion; maintaining contact 13 in the open position is therefore confirmed by the state of rest of the electromagnet.
  • the part 40 moves rapidly in the direction S, towards the position 0, so that the ramp 43 will meet the end 31 and will push the latch 29 down when the part 40 is close to or reaches the stable position O; as soon as the part 40 leaves its position F, the control switch is kept open by the support that the tooth 37 finds against the surface 41.
  • the device is therefore placed in a state of non-service 0, where the electromagnet cannot be excited and where the lever 24 and the latch 29 have been reset.
  • a new commissioning can be obtained by a voluntary action, for example manual, exerted on the member 42 and the part 40 in the direction S to the position F.
  • the reset action of the bolt and of the lever does not occur during the travel of the transmission part going from position F to position 0, but during the movement of this part going from position 0 to position F; in addition, a stable intermediate tripping position indicated by D is provided between position F and position 0 so that, when the transmission part 40 automatically moves from F to 0 following the appearance of a fault, it is stopped in a visible position D which informs the user that the device is in the state open, and that this opening results from the appearance of a fault in at least one circuit.
  • FIG. 4a Such a variant of the apparatus is shown in position F in FIG. 4a, where only the organs necessary for understanding have been represented.
  • a transmission part 40 ' comprises, as before the surfaces 39, 41, a return spring 44 which tends to move this part in the direction S towards a stop 45, and is associated with a control member 42.
  • the region 66 now comprises a tilting lever47 which oscillates around a pivot 48 placed in this region and which cooperates with a spring 51 so as to assume a rest position, which is that shown, and in which this lever 47 is pressed against a stop 50 may or may not belong to this room 40 '.
  • This lever has two successive surfaces 49a, 49 which are directed towards the end 31 and in such a way that, for position F, this end 31 is placed opposite the surface 49.
  • a gap, or notch, or clearance 68 Between the surface 49a and a bearing surface 67 carried by the part 40 'in its vicinity is a gap, or notch, or clearance 68.
  • the elasticity of the spring 51 is chosen such that, when the latch 29 is released towards the top of the figure, the force of its own spring 30 is sufficient to raise the lever 47.
  • a voluntary action, for example manual, exerted in the direction S on the member 42 allows to place the part 40 'in the position 0; during this movement, a slight movement communicated downwards of the figure to the latch 29 by the bearing surface 68 is not sufficient to operate the reset (see fig. 4d).
  • the reset of the lock 29 is operated when the part 40 is brought from its position O towards the position D, and therefore towards the position F, in the direction S; the starting position for resetting is that also shown in fig. 4d.
  • the surface 49a the inclination of which is different from that of the surface 49, is able to impart at the end 31 a fairly substantial downward push. to overcome the force of the spring 30 and produce the reset of the latch 29 as in the previous embodiment.
  • This rearming occurs when the part 40 'is in a position R shown in dotted lines in FIG. 4th.
  • Figs. 2 and 3 represent third and fourth alternative embodiments of the invention, in which a lock 70 (having the same functions as the previous lock 29, in the context of its cooperation with the lever 24) has an end 69 which does not cooperate not directly with part 40 or respectively 47.
  • a second sudden release mechanism 52 is interposed between the first sudden release mechanism 46 and one or more latches 70 similar to the previous one 29.
  • This second mechanism 52 includes a rocker arm 61, a portion 53 of which has an end 60 capable of rocking a locking lever 76 against the action of a spring 59, so that a spout 77 of this lever 76 releases a pusher 54 which is armed by a spring 62;
  • this pusher 54 comprises, on the one hand, in its upper part, an end 55 and a portion 56 similar to the end 31 and to the portion 32 of the latch 29, and comprises, on the other hand, in its lower part, a surface 57 placed opposite a surface 58 belonging to the rocker arm 61.
  • a latch 70 lifts the rocker arm 61 which releases the pusher 54 upwards, the latter in turn co-operating through the portion 56 with the lever 34 to toggle the latter.
  • the rearming of the second abrupt trigger mechanism 52 occurs when the pusher 54 is pushed down in the figure and transmits its movement by cooperation of the surfaces 57, 58 to the rocker arm 61, the latter acting in turn on the end 69 of the latch 70 to restore it to a position where the spring 30 is armed.
  • this downward movement can itself be caused either by the ramp 43 if a transmission part such as 40 is used (see fig. 3), or by the inclined surface 49a if a transmission part such as 40 '(see fig. 2).
  • a device as seen in fig. 2 also makes use of two trigger systems which are each capable of releasing the second abrupt trigger mechanism 52 and which are necessary for separate categories of faults.
  • This pallet can, for example, be crossed by the striker 22 or cooperate with a face of the coil 21 which is not affected by the movements of the striker.
  • an auxiliary pusher 63 whose ends 64, 65 cooperate with this lever and this rocker arm.
  • the striker 22 does not move, but the magnetic attraction of the pallet 75 causes, via the auxiliary pusher 63, the release of the second abrupt trigger mechanism 52, the movement towards 0 of the part 40 ′ and consequently the opening of the control switch 8, the de-excitation of the electromagnet 2 and finally the opening of the power contacts 13 by the effect of the return spring 6.
  • the shape and the arrangement of the various movement transmission elements are given by way of nonlimiting examples, and it must be admitted that the guide surfaces, which are not shown, and which would provide the guidance moving parts in translation, could if necessary be established to guide these parts along curved paths.
  • the local control member 42 makes it possible to operate manually. its commissioning F or its deactivation 0.
