Definitions

  • the present invention relates to a switch electric with fault tripping, of the type comprising: fixed contact means; mobile contact means able to take a working position, in which they cooperate electrically with the fixed contact means, and a rest position for which no cooperation electric does not take place; an actionable lock mechanism by manual control means to put said mobile contact means in either 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 going into active position to trigger said lock mechanism and cause the return of said means contact movable to the rest position under the action said elastic return means.
  • Switches of this type are in particular the differential switches, by example triggered by a relay controlled by a toroid of detection sensitive to a differential current.
  • US-R-2 204 409 describes an electrical switch by default triggering of the aforementioned type.
  • This switch includes a turntable mounted in a switch box and on which is fixed a mobile contact.
  • the board is still in connection with a bistable spring which constitutes one of the elements essential control means.
  • the switch in this document has the disadvantage that in the event of a default trip, always produces a drive control means.
  • the object of the invention is to propose 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 closing of contacts under pressure independent of the lever or another manual actuation member of the switch.
  • the switch comprises in addition to releasable connecting means which can take a engaged position, for which they form a connection mechanical between said lock mechanism and said means contact, and a triggered position, for which said movable contact means are released mechanically said lock mechanism, and by the fact that said connecting means in the engaged position react to the placing the fault detector in the active position by putting 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 return means which are provided mobile contact means, only the inertia specific to means of contact being liable to limit the speed opening of the electrical contact.
  • the lock mechanism may have a mass high total and be associated with visualization means triggers or auxiliary devices detection.
  • the lock mechanism is provided own return means, arranged so as to press towards its rest position when it is decoupled mechanically mobile contact means. Thanks to that characteristic, after tripping of the switch on a fault, the lock mechanism automatically resumes its rest position.
  • the releasable connecting means include: a ramp or abutment surface provided in the movable contact means, an integral retaining element of a part of said lock mechanism and capable of cooperate with said ramp, and a trigger element having a guide surface, this element being able take an engaged position, for which said guide surface holds said retainer against said ramp, and a triggered position for which said guide surface is remote from said ramp.
  • the switch can be provided with temporary stop means likely to take an active position in which they stand in the way of the mobile contact means towards their work position; elastic means of energy storage to allow the continuation of the displacement of the control means towards their position of work while the mobile contact means are stopped and to store the mechanical energy transmitted to said means of contact ; and means for placing in the inactive position said stop means when said lock mechanism reaches the vicinity of its working position.
  • the temporary stop means are provided with elastic return means urging them towards their active position, and the means used to position inactive the temporary stop means include an element integral with the lock mechanism and arranged to move said stop means away from their position active when the lock mechanism is at near his working position.
  • said lock mechanism forms, in cooperation with the mobile contact means and said means of elastic reminder of mobile contact, a mechanical system bistable whose two stable positions, called working and rest, correspond respectively to the positions of work and rest of said mobile contact means.
  • FIGs 1 to 4 schematically represent a differential circuit breaker comprising a contact mobile 50, a fixed contact 51, control means and means of trip on fault, which will be described more far.
  • the words “mobile” and “fixed” are considered here by relation to the chassis (not shown) of the switch.
  • the switch is shown in the initial position - or rest -, contacts 50, 51 open. It has a relay 1, which constitutes a trip device in the event of differential electrical faults occurring on the circuit controlled by the switch.
  • Relay 1 is held in the reset position, supported by a spring 2, by via a reset lever 3 articulated at 3a on the device chassis. This lever 3 takes itself support on a stop 4 of a slide 5 connected functionally in movable contact 50 by means which will be described later with reference to Figures 6 to 10.
  • the slide 5 is mounted on the chassis to vertical sliding, according to Figures 1 to 3, by means not shown, and it is subject to the action of elastic return means tending to move it towards the top of these figures.
  • These return means are shown schematically in Figures 1 to 3 in the form of a powerful spring 5a, ensuring contact pressure.
  • the lock mechanism comprises a lever 6, articulated around an axis 6a on the chassis, susceptible to be mechanically connected to slide 5 by through a rod - or connecting rod - 7 including one end 7a is articulated on lever 6 and the other of which end 7b is capable of acting on a shoulder 11 provided on slide 5 and opening into a groove of oblique guide 11a of the slide 5 in which the end 7b can retract when it escapes shoulder 11.
  • a contact position indicator 8 articulated around an axis 8a on the chassis, is moved angularly, 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 a groove oblique 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 including a ratchet 16 cooperating with a hooking element 17 of an indicator differential release 18 rotatably mounted around a axis which is preferably aligned with axis 8a of the indicator 8.
  • a return spring 19 urges the differential trigger indicator 18 in the direction anti-clockwise (according to figure 3).
  • the trigger 13 is itself blocked in its position, called “engaged position", in which it is shown in Figures 1 and 2, by a ratchet in the form of half-moon 14 rotatably mounted around an axis 14a on the chassis, and associated with a return spring 14b.
  • the trigger 13 thus takes the so-called position "triggered" shown in Figure 3, for which the guide edge 12a disappears, which results in allow 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 part substantially horizontal 12c of the square groove 12, and allow the slider 5 to return to the high position -or 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 choose so that when the guide edge 12a disappears in front of the end 7b, there is a decoupling optimal mechanics between the slide 5, the connecting rod 7 and the trigger 13.
  • the movement towards top of slide 5 can be done very quickly because the slide 5 is mechanically decoupled from all other parts of the control mechanism, so that it is slowed down by inertia and the forces of friction of any of the parts, in motion at that time, the control mechanism of the switch, apart from its own inertia of this slide 5 and the friction forces to which it is subject.
  • Indicator 8 is returned to its original position by the oblique groove 9 of the slide 5.
  • the fault trip display is performed automatically as follows: during rotation, the trigger 13 acts on the pawl 16 which releases the hooking element 17 from the differential trigger 18 which in turn moves in front of window 10 under the action of spring 19.
  • the lever 3 When the slider 5 reaches the vicinity of its high position, the lever 3 is returned to the rearmed position thanks to the action of the stopper 4.
  • the lever 6 returns also in the initial position (which is that of figure 1) by a pivoting caused by the action of a spring of reminder 20 suitably sized, until said lever 6 meets 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 figure 1) of the other parts of the switch control, including that of the trigger 13 under the action of a return spring 22, such that a torsion spring as shown in Figures 4 and 5.
  • differential indicator 18 is returned to the starting position by a new actuation of the lever 6 including an actuating element 6b ( Figure 2) acts on a lever 21 of this indicator 18.
  • Figure 4 shows the trigger 13 in position engaged, while the contacts 50, 51 are closed.
  • the lever arm L1 of action of force f defined above and the arm of lever L2 of the force acting on the pawl 14, are chosen so as to multiply the efforts sufficiently transmitted by the return means 5a to the pawl 14 of the trigger 13, via slide 5, of 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 fault of the switch at the differential relay 1, without that there is a need for parts or intermediate returns.
  • the spring 22 associated with the trigger 13, which is preferably a torsion spring as shown schematically in Figures 4 and 5, is suitably dimensioned and arranged to allow a clearance 23 (figure 1) essential for resetting the pawl 14.
  • Spring 22 also contributes, by an adequate dosage of its strength, to decrease the force exerted on the coupling between trigger 13 and ratchet 14.
  • the end 7b of the rod 7, the groove 11a of the slide 5, and the trigger 13 provided with the groove 12 together form a mechanical connection device releasable capable of coupling and uncoupling mechanically the slide 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 triggered position of trigger 13 such as shown in Figures 1 and 2), it allows the mechanism control 3, 6, 7, 11 to 14 to form, with the slider 5 provided with its elastic return means 5a, a system bistable mechanics whose stable positions correspond, respectively, in the open ( Figure 1) and closed positions ( Figure 2) of the contacts 50, 51.
  • control mechanism 3, 6, 7, 11 to 14 of the switch which has just been described has the advantage require only a small number of parts, while integrating the possibility of performing additional functions such as viewing the trip on fault differential (performed by elements 16 to 19) or indication of the position of the contacts (performed by elements 8 and 9).
  • FIG. 5 shows the arrangement of the parts of the control mechanisms and related functions, sandwiched between two plates 52 and 53 which are kept fixed to each other by means of spacers 54.
  • the limited number of rooms and the arrangement of these between the two plates 52, 53 allow a easy assembly automation, all parts being mounted in a preferred direction on one of the plates, for example plate 52 serving as a base for mounting.
  • the layout shown is particularly adapted to the case where the mobile contact (s) are substantially parallel to the base of the camera body away from the controller.
  • Figure 6 is an exploded view of the part ensuring the "contact" function of the switch differential, this part being represented only very schematically in Figures 1 to 4.
  • This part, shown in Figures 6 to 10 allows rapid closing of contacts, i.e. the very rapid movement of the movable contacts to the fixed contact (s), with a very high contact pressure obtained from the start of closing.
  • This device can be advantageously combined to 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 performed 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 switch chassis.
  • Each blades 100 is mounted in the base 101 so as to ability to move substantially vertically, that is to say transversely to its plane, and able rotate within a certain angular limit around its end 100a opposite to that 100b carrying the contact mobile 50 (see Figure 7).
  • the base 101 houses a breaking chamber which is equipped, as is known, arc extinguishing elements, such as holding plates voltage 102 and deionization plates 103. Terminals connection 104 are placed on either side of the breaking chamber.
  • a temporary stop element 105 is mounted on the base 101, above the contact blades 100, so that ability to rotate around a horizontal axis.
  • 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 later.
  • the breaking chamber is closed by a cover 107, snapped onto the base 101 ensuring compression 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 Figure 6.
  • a contact carrier spring 110 acts on a contact carrier 111 which is mounted in the base 101 to rotation about a horizontal axis. As it will explained below, the spring 110 cooperating with the contact springs 108 is intended to increase the speed opening of the mobile contacts in the event of tripping on default.
  • Figure 7 shows the position "contacts open “of the device.
  • the slide to move down control 5 Figures 1 to 4
  • the contact carrier 111 acts through a surface cam 112, on the blades 100 at a midpoint of these last, in order to move them up against springs 108.
  • the ends 100a of the blades 100 being in support on a stop 101a of the base 101, the blades 100 rotate around their ends 100a, movement tending to bring their end 100b closer, fixed contact 51 associated.
  • the blades 100 are stopped in this rotational movement, shortly before contact closure 50, 51, by a stop 113 placed on the stop element temporary 105. At this precise moment, the latter is trained rotating counterclockwise by a surface of cam 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 joystick command 6, the rotation of element 105 continues until that the stops 113 are located opposite the notches 106 of the blades 100 and enter it causing the closure contacts (figure 10). Contact springs 108 from this moment ensure a contact pressure close to operating pressure.
  • Figures 11 to 15, 16a and 16b show a another embodiment of a differential switch which allows, like the one just described, a closure and rapid opening of the contacts, and in which the contact pressure when the contacts are closed is high and close to the operating pressure.
  • Figure 11 shows schematically switch in reset position, contacts open.
  • the relay 1 is held in the reset position by a spring 200 via a reset lever 201 and a stop 202 of a contact carrier 203.
  • the latter is mounted on the chassis rotating about an 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 rod 206 double bent to form end branches offset from either side of the central lever arm, presses on a central shoulder 210 of contact carrier 203 and is held in position by a guide surface 211, with a concave profile, of a trigger 212, articulated on the chassis in 212a and itself blocked by a ratchet 213 in the shape of a half-moon recalled in locking position by a weak spring (not shown).
  • the contact carrier 203 has an arm 203b which repels down a powerful return spring (not shown) which requests it in the direction of contact opening.
  • the joint 212a is not very far from the shoulder 210 of contact carrier 203.
  • the relay 1 acts on the reset lever 201 which drives in rotation the pawl 213, releasing the spout 212b from the trigger 212 located at the free end of the trigger, which can then, against its weak spring of reminder 223, turn counterclockwise under the pressure of the rod 206 pushed back by the shoulder 210 of the contact carrier 203.
  • the connecting rod 206 escapes by sliding against the guide surface 211 of the trigger 212, allowing contact carrier 203 to return to the "open contacts" position under the influence of return spring acting on the arm 203b without being slowed down by any of the elements of the command 6, 201, 204 to 206 and 211 to 213.
  • the indicator rotary 207 is returned to its initial position by the groove oblique 208 of the contact carrier 203 which drives an arm 207a of the indicator.
  • the trigger 212 raises, by a relief 212c, a trigger indicator sliding differential 220 and indicator 220 normally blocked by a spout 220a against a fixed stop 219 against which pushes its return spring 221, moves in front of a window 222.
  • the indicator 220 drives counter-clockwise 226 pivoting about an axis 226a which allows the transmission of the rotational movement to a device usual auxiliary which can be coupled to the switch differential.
  • the connecting piece 226 can be coupled to an appliance auxiliary, through a light in the wall of the housing the switch, is driven until a ramp 220b of the indicator 220 meets a fixed relief 220c, which raise the pointer and release room 226.
  • the auxiliary device if the auxiliary device is present, its mechanism, coupled to Exhibit 226 prohibits the return thereof, which, if not, would have occurred under the effect of its elastic return means 226b, and this until the user has rearmed the auxiliary device. In this position the part 226 prevents the pawl 213 from returning to the rest position so that the manual reset of the switch according to the invention is precluded because the guide surface 211 always lets out the end 206a of the connecting rod 206 out of reach of the contact carrier.
  • Exhibit 226 has been returned to its original position, releasing the arm 213a from the pawl 213, and the user can then reset the switch, causing clockwise rotation of indicator 207, which pushes the indicator of differential trigger 220 until hooking behind the stop 219 and taking care of the end or spout 226c of connecting piece 226. If the auxiliary device is not present, it is the elastic return means 226b which will have brought the part 226 back into the rest position.
  • Joystick 6 returns to the open position (from rest) under the action of its return spring 20, in authorizing the replacement of all parts of the control mechanism 201, 204 to 206 and 211 to 213 as shown in Figure 11.
  • the trigger indicator differential 220 if it has been activated, is reset, as saw it, by the next engagement of the mechanism lock by rotating the position indicator contacts 207.
  • the dimensioning of the lever arms L3, L4 and L5 allows to sufficiently multiply the efforts transmitted by contact springs (shown schematically in Figures 11 to 15 in the form of a spring 225 interposed between the contact carrier 203 and the contact 214) through the shoulder 210 of the contact carrier 203 to limit the force required to trip on switch fault, by differential relay 1, without that there is a need for parts or intermediate returns.
  • the spring 223, acting on the trigger 212 contributes, by an adequate dosage of its strength, to decrease the strength exerted on the coupling between trigger 212 and pawl 213.
  • This arrangement ensures optimal use efforts, in which the rod 206 rests on the contact carrier at a point 206a located on a spoke geometric of 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 fairly consistent thrust from the spring 217.
  • Figures 16a and 16b show, by views exploded, the main elements of the embodiment of Figures 11 to 15, mounted on either side of a plate 227 which allows to separate, on either side of a median plane of the device, represented by the plate, a space lock mechanism (Fig 16a) and a release space (Fig 16b).
  • Figure 17 shows the mechanism elements of mobile contact which are only represented very schematically by elements 203, 214 and 225 in the figures 11 to 14, this mechanism being able to be independent of the device described in Figures 11 to 16.
  • Movable contact blades 214 are placed vertically in the base 301 of the device so as to clear a place for a current measuring device differential 302.
  • the switching chamber is equipped of extinguishing elements of the arc which is created at the opening contacts.
  • these extinguishing elements consist of sheets of voltage maintenance 303 and deionization sheets 304.
  • Connection terminals 305 are placed on the one hand above the switch-off chamber and on the other hand below the measuring elements 302.
  • Preferably temporary stop elements 306 are placed above a contact carrier 203 and cooperate with notches 308 formed in the blades 214 as well as with tongues 309 of the contact carrier 203.
  • a return spring 310 acts on the arm 203b of the contact carrier 203.
  • the contact pressure is ensured by torsion springs 225 of which each leaf 214 is equipped. One end 312 of each of the springs is pressing on the contact carrier 203, while the part center of each spring 225 is fixed to the blade 214 associated and that the other end 311 of this spring 225 is resting on the base 301.
