Definitions

  • the present invention relates to a safety device intended for a switching device produced by the assembly of several removable modular elements.
  • the object of the invention is therefore more particularly to provide a safety device which makes it impossible to mount or extract the control modules when the switch is not in a determined state (for example the open state).
  • a safety device for a device of the aforementioned type comprising a switch module on which an indirect action control module can be fixed by means of a screw mounted axially sliding in a through passage provided in said control control module. so that in the assembled position of this control module on the switch module, it can be screwed into a coaxial threaded hole provided in the switch module, and that at the end of screwing, the control module is tightened against the module switch thanks to the action of the screw head on a fixed surface of the control module.
  • this device is more particularly characterized in that it comprises means capable of preventing access from the head of the screw and, consequently, any possibility of screwing or unscrewing, when the control module n is not in the armed state.
  • these prohibition means may consist of a prohibition element secured to the manual control member provided for arming the indirect switching control module.
  • the length of the threaded end of the screw coming to be screwed into the aforesaid tapped hole will preferably be provided at least equal to the actuating stroke of the moving element of the switch module.
  • the above-mentioned prohibition means will be designed so as to ensure, in cooperation with the abovementioned stop, an axial locking of the screw (by imprisonment of the head).
  • This arrangement ensures that an attempt to assemble a control module in the tripped state on a switch module cannot generate an action on the moving element of this switch module, and this, due to the presence of the threaded end of the screw that protrudes outside the control module. Indeed, this threaded end will prevent any possibility of contact of the actuation means of the control module on the moving element.
  • This safety measure will be increased through the use of guide means associated with the switch module and the control module to ensure that the assembly of these two modules can only be performed after a relative movement of translation parallel to the axis of the screw, over a distance at least equal to the length of the end of the screw which protrudes outside the control module, when the head of the screw is in contact with its bearing surface.
  • the invention applies, in a particularly advantageous manner, to a switching device consisting of a contactor-limiter involving a switch module, a removable indirect switching control module and a direct switching control module (removable or incorporated in the switch module).
  • the safety device will aim to prohibit any possibility of assembly (or extraction) of the indirect switching control module, not only when this module is not in the armed state, but in addition when the direct switching control module is enabled to operate.
  • control means will be designed so as to close the safety switch only in the "auto” position while the prohibition means will be provided so as to not allow access to the head of the screw only when these control means are in the "off" position.
  • this switch which is shown very schematically, can also include all the equipment with which the switches are usually fitted, such as, for example, arc splitting fins, decompression channels, etc. elsewhere, the conductors 5 and 6 have a folded shape allowing the development of repulsion forces acting on the movable contact carrier 9, under the effect of the current flowing in the switch.
  • This assembly face 21 has, in its middle part, a partition 22 which extends perpendicularly to the longitudinal faces 15, 16 and to the assembly face 21.
  • This partition 22 separates the assembly face 21 into two zones, namely, a zone Z1 intended to receive a direct control module 23 and a zone Z2 intended to receive an indirect control module 24. It comprises, on the side of the assembly zone Z2, a stepped profile P1 and, on the side of the zone Z1, a flat face F perpendicular to the assembly face 21.
  • Zone Z1 comprises, in the vicinity of the partition 22, three orifices O aligned perpendicular to the longitudinal faces 15, 16, through which the pushers 12 of the three switches pass.
  • the lateral faces 17, 18 each have three orifices C1, C2, C3 for access to the connection devices 7, 8 whose clamping screws 25, 25 ′ are accessible by means of orifices Aifices, A2, A3, A′1, A′2 correspondents provided in the assembly face 21.
  • the direct control device 23 comprises a housing B2 of parallelepiped shape which is fixed by its base 26 on the assembly zone Z1 slightly set back from the zone Z′1 in which the pushers 12 stand out.
  • This box B2 contains an electromagnet 27 whose movable armature 28 (or the core) is connected to a lever 29 used for actuating the pushers 12 of the switches.
  • the end of the lever 29 located opposite its connection to the frame 28 cooperates with a rake 30 movable in translation in the interval between the housing B2 and the partition 22 and supported by the pushers 12 of the three switches.
  • the lever 29 and the rake 30 are then arranged so that the excitation of the coil of the electromagnet 27 generates a tilting of the lever 29 which causes a translational movement of the rake 30 and the three pushers 12, at the against the action exerted by the springs 13, in the direction of opening of the contacts 3, 4 - 10, 11.
  • the excitation of the coil 31 of the electromagnet is ensured by means of a remote control circuit connecting to two terminals 32, 33 provided on the housing B2 and comprising a switch 34 arranged in series.
  • This switch 34 is controlled by a pusher 35 accessible by an opening provided on the face 36 of the housing B2 located opposite the partition 22.
  • the indirect switching control module 24 comprises both a triggering device with potential accumulation and the protection devices associated with it, such as, for example, an electromagnet intended to cause the triggering of the device in response. has abrupt overcurrents or short-circuits, a thermal protection system, for example, bimetal intended to cause tripping following abnormal elevations of intensity lasting over time.
  • the second actuating member 50 can also take a retracted position in which it does not stress the plunger 35 and a deployed position in which it acts on the plunger 35 so as to close the switch 34 of the control module 23, the passage from the retracted position to the deployed position being effected by passing the button 45 from the "off" position (that is to say arming) to an "auto" position.
  • the triggering device 46 further comprises a triggering member 52 represented here by a pusher which, when it is pressed, causes the first actuation member 48 to pass suddenly, from its retracted position to its deployed position.
  • the protection devices 53 associated with the triggering device 46 which are housed here in the indirect switching control module 24, have been represented diagrammatically by a block in FIG. 2.
  • actuating member 54 represented by a pusher
  • triggering member 52 following the detection of an anomaly of the current passing through the power switches of the module 1.
  • the electrical connections between the current lines passing through these power switches and these protection devices 53 are established by means of three pairs of male 55 and female 56 connection elements respectively provided on the shelves 57, 58 opposite the modules 1 and 23; the male connection elements 55 are connected to the protective devices 53 by means of links 59, while the female connection elements 56 are respectively connected to the conductors 5 of the power switches.
  • the male connection elements 55 are designed so as to respectively engage in the female connection elements 56 during assembly of the indirect switching control module 24 on the switch module 1.
  • this assembly is ensured by bringing the module 24 onto the module 1 at the end of a translational movement perpendicular to the assembly face 21.
  • the module 24 is guided by guide wings 61, 62 - 61 ′, 62 ′ which extend the longitudinal faces 15, 16 in regions adjacent to the partition 22 and to the transverse edge 63 and terminate at the level of the upper stage 64 of the partition 22.
  • the attachment of the indirect switching control module 24 to the switch module 1 is ensured by means of at least one screw 65 which engages in a through passage of the housing B3 to come to be screwed (in the assembled position of the modules 1 and 24) in a tapped hole 66 provided in the step 64 of the partition 22, the axis of the screw 65 and that of the hole 66 being perpendicular to said step 64.
  • the head 67 of the screw 65 engages in a well 68 produced on the stage 44 of the front face 43 in the area of rotation of the flange 69 of the cocking button 45.
  • the flange 69 of the button 45 has a notch 70 arranged so as to coincide with the well 68 only when the button 45 is in the "off” position.
  • the button when the button is not in the "off” position, it therefore becomes impossible to disassemble the modules 1 and 24 or, on the contrary, to assemble them.
  • the guide wings 61, 61 ′ - 62, 62 ′ and the fact that the head 67 of the screw 65 is trapped in the well 68 by the flange 69 of the button 45 an attempt to assemble the two modules 1, 24 cannot lead to accidental actuation of the power switches; the module 24 will be kept away from the module 1 by the screw 65.
  • the length of the portion of the screw 65 emerging from the module 24 will be provided greater than the length of the stroke of the actuating member 48, so that the latter cannot come to bear on the rake 30 during such an attempt.
  • the screw 65 can be biassed axially by a spring, so that in the unscrewed position, it remains engaged in the notch 70 and thus prohibits any operation of the button 45.
  • the attachment of the module 24 to the module 23 is, moreover, ensured by means of a tongue 71, integral with the housing B3, which extends parallel to the lateral face 42 from the tier 44 and which engages in a slot provided on the face 72 of the housing B2.
  • This arrangement makes it possible in particular to avoid a separation of the housings B2 and B3 under the effect of the pressure exerted by the actuating member 50 on the pusher 35.
  • the notch 70 of the flange 69 is in coincidence with the well 68, and the head 67 of the screw 65 is accessible, either for assembly or for disassembly.
  • the actuating members 48, 50 are in the retracted state and the module 24 is in the armed state.
  • This module has no action on the switch module 1 and the direct switching module 23 is inhibited due to the fact that the switch 34, which is not pressed, is in the open state.
  • the triggering member 52 When the triggering member 52 is requested by the protective devices 53, it causes the actuating member 48 to pass to the deployed position, thereby causing the power switches of the module 1 to open. , the button 45 rotates 45 ° counterclockwise, position in which the flange 69 prohibits access to the head 67 of the screw 65 ( Figure 5).
  • Resetting is then obtained by rotating the button 45 75 ° counterclockwise to the "arming" position shown in Figure 6, then returning the button (clockwise) to the "stop” position shown in Figure 3. The button can then be returned to the "auto” position in Figure 4.
  • the device according to the invention achieves very high security, while being very simple and non-binding for the user.
