Definitions

  • the present invention relates to an electric switch with trip on fault, of the type comprising: fixed contact means; movable contact means capable of assuming a working position, in which they cooperate electrically with the fixed contact means, and a rest position for which no electrical cooperation takes place; a lock mechanism, operable by manual control means for placing said movable contact means in one or the other of said positions; elastic return means for urging the movable contact means towards their rest position; and an electrical fault detector reacting to a fault by moving to the active position to trigger said lock mechanism and cause said movable contact means to return to the rest position under the action of said elastic return means.
  • Switches of this type are in particular differential switches, for example triggered by a relay controlled by a detection toroid sensitive to a differential current.
  • the invention aims to provide a switch of this type which allows on the one hand a rapid opening of the contacts in the event of a fault and on the other hand a closing of the contacts under pressure independent of the lever or other actuating member. switch manual.
  • Another objects of the invention are to provide a simple device architecture that facilitates mounting, to optimize the forces transmitted by the different parts of the mechanism, and to ensure effective display or detection of trips.
  • the switch further comprises releasable connection means which can assume an engaged position, for which they form a mechanical connection between said lock mechanism and said means of movable contact, and a triggered position, for which said movable contact means are released mechanically from said lock mechanism, and by the fact that said connecting means in the engaged position react to the active positioning of the fault detector by setting in the triggered position.
  • the movable contact means are mechanically decoupled from said lock mechanism and its control means, so that the switch is quickly put in the open position by the action of the elastic means. reminder with which the mobile contact means are provided, only the inertia proper to the contact means being capable of limiting the speed of the opening of the electrical contact.
  • the lock mechanism may have a high total mass and be associated with means for visualizing trips or with auxiliary detection devices.
  • the lock mechanism is provided with its own return means, arranged so as to urge it towards its rest position when it is mechanically decoupled from the movable contact means. Thanks to this characteristic, after tripping of the switch on a fault, the lock mechanism automatically returns to its rest position.
  • the releasable connecting means comprise: a ramp or abutment surface provided in the movable contact means, a retaining element integral with a part of said lock mechanism and capable of cooperating with said ramp, and a trigger element comprising a guide surface, this element being able to assume an engaged position, for which said guide surface maintains said retaining element against said ramp, and a triggered position for which said guide surface is distant from said ramp.
  • the switch can be provided with temporary abutment means capable of assuming an active position in which they are interposed on the path of the movable contact means towards their working position; elastic energy storage means to allow further movement of the control means towards their working position while the movable contact means are stopped and to store the mechanical energy transmitted to said contact means; and means for placing in the inactive position said stop means when said lock mechanism reaches the vicinity of its working position. Thanks to this use of temporary abutment means which disappear when the lock mechanism reaches a position close to its working position, a high contact pressure close to the operating pressure is obtained as soon as the contacts are closed.
  • the temporary abutment means are provided with elastic return means urging them towards their active position, and the means serving to place the temporary abutment means in the inactive position comprise an element integral with the lock mechanism and arranged to separate said means from stop of their active position when the lock mechanism is in the vicinity of its working position.
  • said lock mechanism forms, in cooperation with the mobile contact means and said elastic return means of mobile contact, a bistable mechanical system whose two stable positions, called work and rest , respectively correspond to the working and rest positions of said movable contact means.
  • FIGS. 1 to 4 schematically represent a differential circuit breaker comprising a movable contact 50, a fixed contact 51, control means and trip means on fault, which will be described more far.
  • the words “mobile” and “fixed” are considered here with respect to the chassis (not shown) of the switch.
  • the switch is shown in the initial position - or rest -, contacts 50, 51 open. It includes a relay 1, which constitutes a tripping device in the event of differential electrical faults occurring on the circuit controlled by the switch.
  • the relay 1 is held in the reset position, supported by a spring 2, by means of a reset lever 3 articulated at 3a on the chassis of the device.
  • This lever 3 is itself supported on a stop 4 of a slide 5 functionally connected to the movable contact 50 by means which will be described later with reference to FIGS. 6 to 10.
  • the slider 5 is mounted on the vertically sliding chassis, according to FIGS. 1 to 3, by means not shown, and it is subjected to the action of elastic return means tending to move it upwards in these figures.
  • These return means are shown schematically in Figures 1 to 3 in the form of a powerful spring 5a, ensuring the contact pressure.
  • the lock mechanism comprises a lever 6, articulated around an axis 6a on the chassis, capable of being mechanically connected to the slide 5 by means of a rod - or connecting rod - 7, one end of which 7a is articulated on the lever 6 and whose other end 7b is capable of acting on a shoulder 11 provided on the slide 5 and opening into an oblique guide groove 11a of the slide 5 in which the end 7b can be retracted when it escapes the shoulder 11.
  • a contact position indicator 8 articulated around an axis 8a on the chassis, is angularly displaced, during the vertical displacement of the slide 5, by the action of an end 8b of an extension 8c of said indicator 8.
  • the end 8b slides in an oblique groove 9 of the slide 5.
  • the indicator 8 indicates, through a window 10, the position (closed or open) of the contacts 50, 51 of the switch.
  • the switch shown further comprises a differential fault display member comprising a pawl 16 cooperating with a latching element 17 of a differential trigger indicator 18 rotatably mounted about an axis which is preferably aligned with the axis 8a of the indicator 8.
  • a return spring 19 urges the differential trigger indicator 18 counterclockwise (according to FIG. 3).
  • the trigger 13 is itself blocked in its position, called “engaged position", in which it is represented in FIGS. 1 and 2, by a pawl in the shape of a half-moon 14 rotatably mounted around an axis 14a on the chassis, and associated with a return spring 14b.
  • the placing in the closed position of the contacts 50, 51 is accomplished when the movement of the lever 6 is stopped by a closing end-of-travel stop (not shown). At this moment, the position of the slide 5 corresponds to the setting in the closed state of the contacts 50, 51 (FIG. 2).
  • the relay 1 acts on the lever 3 which is free to pivot down, the stop 4 having been erased.
  • the lever 3 rotates the pawl 14, releasing the attachment of the trigger 13 which is then free to rotate around the axis 13a, clockwise, under the pressure of the end 7b of the connecting rod 7, end exerting a force f (FIG. 4) on the guide edge 12a of the groove 12.
  • the end 7b is, in fact, itself pushed upwards by the shoulder 11 of the slide 5 itself subject to the action of the return means 5a ( Figure 3).
  • the trigger 13 thus takes the so-called "triggered" position shown in FIG. 3, for which the guide edge 12a disappears, which has the consequence of allowing the end 7b of the rod 7 to slide along an oblique edge 11b extending downward the shoulder 11 of the groove 11a, as well as along the substantially horizontal part 12c of the angled groove 12, and allowing the slide 5 to return to the high position or the rest position - corresponding to the open state of contacts 50, 51.
  • the angle of inclination of the edge 11b of the groove 11a, as well as that of the part 12c of the groove 12 are chosen so that, at the moment when the guide edge 12a disappears in front of the end 7b, there has an optimal mechanical uncoupling between the slide 5, the connecting rod 7 and the trigger 13.
  • the upward movement of the slider 5 can be carried out very quickly because the slider 5 is at this time mechanically decoupled from all the other parts of the control mechanism, so that it is not slowed down by the inertia and the frictional forces of any of the parts, in motion at that time, of the control mechanism of the interrupter, apart from the own inertia of this slider 5 and the frictional forces to which it is subjected.
  • the indicator 8 is returned to its initial position by the oblique groove 9 of the slide 5.
  • the display of the trip on fault is carried out automatically in the following way: during rotation, the trip 13 acts on the pawl 16 which releases the latching element 17 from the differential trigger indicator 18 which, in turn, moves in front of the window 10 under the action of the spring 19.
  • the lever 3 When the slide 5 reaches the vicinity of its high position, the lever 3 is returned to the rearmed position by the action of the stopper 4.
  • the lever 6 also returns to the initial position (which is that of FIG. 1) by a pivoting caused by the action of a suitably dimensioned return spring 20, until said lever 6 encounters an opening end-of-travel stop (not shown).
  • This return to the initial position of the lever 6 is accompanied by the return to the starting position (position of FIG. 1) of the other parts of the switch control mechanism, and in particular that of the trigger 13 under the action of a return spring 22, such as a torsion spring as shown in FIGS. 4 and 5.
  • differential indicator 18 is returned to the starting position by a new actuation of the lever 6 of which an actuating element 6b (FIG. 2) acts on a lever 21 of this indicator 18.
  • Figure 4 shows the trigger 13 in the engaged position, while the contacts 50, 51 are closed.
  • the lever arm L1 of action of the force f defined above and the lever arm L2 of the force acting on the pawl 14, are chosen so as to sufficiently increase the forces transmitted by the return means 5a to the pawl 14 of the trigger 13, by means of the slider 5, the shoulder 11, the end 7b of the rod 7, and the edge 12a of the groove 12. This reduction makes it possible to limit the force required to trip on a switch fault at the differential relay 1, without the need for intermediate parts or references.
  • the spring 22 associated with the trigger 13, which is preferably a torsion spring as shown diagrammatically in FIGS. 4 and 5, is suitably sized and arranged to allow play 23 (FIG. 1) essential for resetting the pawl 14.
  • the spring 22 contributes also, by an adequate dosage of its force, to reduce the force exerted on the coupling between trigger 13 and pawl 14.
  • the end 7b of the rod 7, the groove 11a of the slider 5, and the trigger 13 provided with the groove 12 together form a releasable mechanical connection device capable of mechanically coupling and uncoupling the slider 5 and the control mechanism 3 , 6, 7, 11 to 14.
  • this connecting device 7b, 11a, 13 When this connecting device 7b, 11a, 13 is in the active - or engaged - position (position which corresponds to the engaged position of the trigger 13 as shown in Figures 1 and 2), it allows the control mechanism 3, 6, 7, 11 to 14 to form, with the slider 5 provided with its elastic return means 5a, a bistable mechanical system whose stable positions correspond, respectively, to the open (FIG. 1) and closed positions ( Figure 2) of the contacts 50, 51.
  • connection device 7b, 11a, 13 when the connection device 7b, 11a, 13 is in the disengaged - or inactive - position (FIG. 3), the control mechanism 3, 6, 7, 11 to 14 constitutes, thanks in particular to the return spring 20 of handle 6, a monostable mechanical system tending to return to its position shown in FIG. 1.
  • control mechanism 3, 6, 7, 11 to 14 of the switch which has just been described has the advantage of requiring only a small number of parts, while incorporating the possibility of carrying out additional functions such as the display of the trip on differential fault (carried out by elements 16 to 19) or the indication of the position of the contacts (carried out by elements 8 and 9).
  • FIG. 5 shows the arrangement of the parts of the control mechanisms and associated functions, sandwiched between two plates 52 and 53 which are held fixed to one another by means of spacers 54.
  • the limited number of parts and the arrangement of these between the two plates 52, 53 allow easy assembly automation, all the parts being mounted in a preferred direction on one of the plates, for example the plate 52 serving as mounting base.
  • the arrangement shown is particularly suitable for the case where the movable contact or contacts are substantially parallel to the base of the housing of the device remote from the lever.
  • FIG. 6 is an exploded view of the part ensuring the "contact" function of the differential switch, this part being shown only very schematically in FIGS. 1 to 4.
  • This part represented in FIGS. 6 to 10, allows the rapid closure of the contacts, that is to say the very rapid movement of the movable contact (s) towards the fixed contact (s), with a very high contact pressure obtained from the start of the closure.
  • This device can advantageously be associated with the device according to FIGS. 1 to 5, but it can also be mounted independently on any other switch. According to the example shown, this function is provided by two movable contact blades 100 (see also Figures 7 to 10) which are placed substantially horizontally in a base 101 forming part of the chassis of the switch.
  • each of the blades 100 is mounted in the base 101 so as to be able to move substantially vertically, that is to say transversely to its plane, and to be able to pivot within a certain angular limit around its end 100a opposite to that 100b carrying the movable contact 50 (see FIG. 7).
  • the base 101 houses a breaking chamber which is equipped, as is known, with arc extinguishing elements, such as voltage-maintaining plates 102 and deionization plates 103.
  • Connection terminals 104 are placed on the side and on the other side of the breaking chamber.
  • a temporary stop element 105 is mounted on the base 101, above the contact blades 100, so that it can rotate around a horizontal axis.
  • the element 105 which is returned to a rest position by a spring not shown, is intended to cooperate with the blades 100 which are each provided with a notch 106 whose role will be explained below.
  • the interrupting chamber is closed by a cover 107, snapped onto the base 101 ensuring the compression of contact springs 108 each associated with a blade 100.
  • the cover 107 also carries supports 109 for the fixed contacts 51, as well as other parts of the switch which are not shown in FIG. 6.
  • a contact carrier spring 110 acts on a contact carrier 111 which is mounted in the base 101 in rotation about a horizontal axis. As will be explained below, the spring 110 cooperating with the contact springs 108 is intended to increase the opening speed of the movable contacts in the event of tripping on a fault.
  • Figure 7 shows the position "open contacts" of the device.
  • the operating member (handle 6) of the differential switch By acting on the operating member (handle 6) of the differential switch, it causes the downward movement of the control slide 5 ( Figures 1 to 4), which causes the pivoting of the contact carrier 111 in the direction timetable (figure 8).
  • the contact carrier 111 acts, by a cam surface 112, on the blades 100 at a midpoint of the latter, in order to move them up against the springs 108.
  • the ends 100a of the blades 100 being supported on a stop 101a of the base 101, the blades 100 perform a rotational movement around their end 100a, movement tending to bring their end 100b closer to the fixed contact 51 associated.
  • the blades 100 are stopped in this rotary movement, shortly before the closure of the contacts 50, 51, by a stop 113 placed on the temporary stop element 105. At this precise moment, the latter is rotated in the anti-direction - schedule by a cam surface 114 of the contact carrier 111. In this phase of the movement which corresponds to FIG. 9, the blades 100 rotate around the cam surface 112 by compressing their spring 108. If one continues to act on the control handle 6, the rotation of the element 105 continues until the stops 113 are opposite the notches 106 of the blades 100 and enter it causing the contacts to close ( Figure 10). The contact springs 108 ensure from this instant a contact pressure close to the operating pressure.
  • FIGS. 11 to 15, 16a and 16b show another embodiment of a differential switch which allows, like the one just described, rapid closing and opening of the contacts, and in which the contact pressure at the time contact closure is high and close to operating pressure.
  • FIG. 11 schematically represents the switch in the reset position, contacts open.
  • Relay 1 is held in the reset position by a spring 200 by means of a reset lever 201 and a stop 202 of a contact carrier 203.
  • the latter is mounted on the chassis with rotation around a axis 203a.
  • a contact position indicator 207 driven by an oblique groove 208 of the contact carrier 203, indicates the closed position of the contacts through a window 209 formed on a cover (not shown) of the chassis of the device.
  • the connecting rod 206 doubly bent to form end branches offset on either side of the central lever arm, presses on a central shoulder 210 of the contact carrier 203 and it is held in position by a guide surface 211, with a concave profile, a trigger 212, articulated on the chassis at 212a and itself blocked by a pawl 213 in the shape of a half-moon returned to the blocking position by a weak spring (not shown).
  • the contact carrier 203 has an arm 203b which pushes down a powerful return spring (not shown) which biases it in the direction of contact opening.
  • the articulation 212a is not very far from the shoulder 210 of the contact carrier 203.
  • the relay 1 acts on the reset lever 201 which rotates the pawl 213, by releasing the spout 212b of the trigger 212 located at the free end of the trigger, which can then, at against its weak return spring 223, turn anti-clockwise under the pressure of the rod 206 pushed back by the shoulder 210 of the contact carrier 203.
  • the rod 206 escapes by sliding against the guide surface 211 of the trigger 212, allowing the contact carrier 203 to return to the "open contacts" position under the influence of the return spring acting on the arm 203b without being slowed down by any of the elements of the mechanism 6, 201, 204 to 206 and 211 to 213.

  • the auxiliary device if the auxiliary device is present, its mechanism, coupled to the part 226, prohibits the return of the latter, which, otherwise, would have taken place under the effect of its reminder elastic 226b, and this until the user has reset the auxiliary device.
  • the part 226 prevents the pawl 213 from returning to the rest position, so that manual resetting of the switch according to the invention is prevented, because the guide surface 211 always lets the end 206a escape. the rod 206 out of range of the contact carrier.
  • the part 226 has been returned to its initial position, freeing the arm 213a from the pawl 213, and the user can then reset the switch, causing the clockwise rotation of the indicator 207, which pushes the differential trigger indicator 220 until it is hooked behind the stop 219 and when the end or spout 226c of the connecting piece 226 is taken over.

  • the spring 223, acting on the trigger 212 contributes, by an adequate dosage of its force, to reduce the force exerted on the attachment between trigger 212 and pawl 213.
  • This arrangement ensures optimal use of forces, in which the rod 206 rests on the contact carrier at a point 206a located on a geometric radius of the contact carrier 203 almost perpendicular to the rod 206, which makes the best use of the thrust of the spring 217 amplified by lever 218 in a position forming an obtuse angle with the connecting rods 205, 206, favoring a fairly great constancy of the thrust coming from spring 217.
