Definitions

  • the invention relates to the electrical energy distribution pipe elements.
  • the invention therefore provides a modular element of energy distribution pipe, consisting of a long box in which are longitudinally arranged conductive bars of electric power distribution laterally accessible through distribution openings of the box at least some are protected by a protective closure device in the absence of a bypass, this element being designed to simplify and facilitate the assembly and operation of the distribution circuits of an installation.
  • the box of a modular element comprises two longitudinally grooved beams on either side of which are fixed two profiled strips, with trough section, whose respective longitudinal edges are inserted elastically and s' each immobilizes in a groove of a beam by delimiting a longitudinal cavity in which are housed conductive bars of medium power distribution.
  • FIG. 1 presents a partially exploded perspective view of a portion of pipe made up of modular elements according to the invention.
  • Figure 2 shows a cross section of a modular pipe element according to the invention, made at a bypass hatch.
  • the electrical energy distribution channel portion presented in FIG. 1 is shown composed of two modular elements 1 intended to be connected at the end.
  • Each modular element comprises an elongated box 2 in which are arranged longitudinally conductive bars 3 of medium power distribution of electrical energy, for example three phase bars and a neutral bar; a protective conductor is associated with these bars, it is for example constituted by a conductive beam of the box, such as 8 or 9.
  • the bars 3 are accessible on the one hand, at the end, at least one end of the box 2 which contains them, on the other hand through lateral distribution openings 4 arranged for example alternately on two opposite sides of the box 2, along this box, if necessary.
  • Connecting members known in themselves and not shown, make it possible to ensure electrical continuity between corresponding bars 3 of two modular elements 1 placed end to end.
  • junction members are enclosed under a cover formed by two complementary and here identical half-shells 5 which are positioned on the assembled ends of two boxes 2 placed end to end, on either side of the assembly formed so as to constitute a protective sleeve.
  • One of these shells provides for example the support of the electrical junction element mentioned above.
  • the bars 3 are conventionally held in place in their casing by fixing blocks 6, for example of the insulating comb type, such a fixing block, here common to the different bars 3 and for example in one piece, being shown in FIG. 2.
  • the box of a modular element is produced using profiled sheet metal strips 7 longitudinally secured to the joining beams referenced 8 and 9 in the figures.
  • a modular element comprises two identical profiled strips 7, both having a trough cross section so as to delimit a cavity for housing conductive bars 3, when they are suitably joined with only their longitudinal edges close together.
  • each profiled strip 7 comprises a long flat median zone laterally bordered by two zones which are symmetrically arcuate with respect to a longitudinal plane of symmetry of the strip, to give a determined transverse elasticity to this strip.
  • the required elasticity can also be obtained with a symmetrical structure with roughly equivalent complementary sides of inclination or by using a strip having only one arcuate area or sides along one edge. of a flat longitudinal zone, the other edge of which is then fixed on one of the beams 8 or 9.
  • the lateral distribution openings 4 are here formed in the flat central zone of the strip.
  • Each of the beams 8 and 9 has a longitudinal groove 10 on two opposite sides, this groove is shaped to receive and fix a longitudinal edge of profiled strip 7 which is just inserted therein, during the assembly of the box 2 which comprises it .
  • Each longitudinal edge of the profiled strip is shaped by folding or roller burnishing so as to be wedged elastically in the longitudinal fixing groove where it is inserted, the latter being configured in a complementary manner to allow this fixing, according to techniques well known in this field. which will not be recalled here.
  • the beam 8 is intended to serve as a hooking element for the box of the modular element 1 which comprises it, it is preferably constituted by a symmetrical profile comprising a longitudinal groove 11 with a T profile , laterally bordered on each of its two sides by one of the longitudinal grooves 10 for fixing the profiled strip 7.
  • a longitudinal central slot 11A for access to the longitudinal groove 11 of beam 8 is provided open, at the edge of the box, between the curved zones two profiled strips 7 which are fixed on either side of this beam, it consequently allows the attachment of the modular element which comprises it to a support element in particular to a suspension hook, not shown, for example it -Even in T, which is introduced into the longitudinal groove 11 of complementary shape.
  • the beam 8 is for example constituted by an aluminum profile which allows its use as a ground conductor.
  • the beam 9 is preferably also constituted by an aluminum profile which has a longitudinal groove 10 for fixing a profiled strip on two of its sides.
  • This beam 9 comprises a central longitudinal cavity 12 provided with a through slot 12A which is oriented in a direction parallel to that of the grooves 10 and which opens at the edge of the box, between the curved zones of the two profiled strips 7 of the box, and opposite the longitudinal groove 11 of the beam 8.
  • the longitudinal cavity 12 is internally lined with longitudinal conductive bars 13 of a type in particular intended for a relatively moderate power distribution, of the lighting type, allowing for example the passage of electric currents of the order of 20 to 40 amps , or of the remote control type, for example for triggering or resetting remote electrical components, for monitoring electrical receivers.
  • these bars 13 are fixed inside the cavity by pinching in fixing parts, such as 14, made of insulating material.
  • the latter leave most of the bars conductive 13 exposed to allow the establishment of a bypass, practically at any chosen location along the modular element.
  • Such a bypass is established for example by means of a specialized bypass plug, known per se, such as 15 - see FIG. 1 - partially penetrating into the cavity 12 through the slot 12A to come into abutment against the bars conductive 13 by contact parts not shown, as conventional in this field.
  • a bypass plug known per se, such as 15 - see FIG. 1 - partially penetrating into the cavity 12 through the slot 12A to come into abutment against the bars conductive 13 by contact parts not shown, as conventional in this field.
  • a modular element 1 is capable of comprising one or more lateral distribution openings 4 which, each comprise a closure device, a movable flap 16 of which must be moved if a branch connection is made.
  • Each device comprises, for example and according to a conventional embodiment, a shutter flap 16, fixed, provided with parallel slots and an internal flap 17, of insulating material, which is provided with parallel slots corresponding to those of the flap at along which this shutter is capable of sliding.
  • the flap In the absence of a bypass, the flap is resiliently pushed back, for example by a spring 18, so that the slots in the flap 17 do not face those of the flap 16 and that the flap-flap assembly insulates the busbars 3 distribution medium power energy of any contact with the outside through the lateral distribution opening 4 which comprises the shutter and the hatch considered.
  • the matching of the slots of the flap 17 and the hatch 16 of an opening 4 allows the introduction of parallel contacts, of the blade type, of a suitable known bypass socket, in the longitudinal cavity 11, through of these slots and against the conductive bars 3 and the protective beam 8, corresponding.
  • the beam 9 of a box tends to be resiliently biased towards the beam 8 of this box by the profiled strips 7 due to the relative elasticity of the sheets which constitute the and their respective curvatures.
  • the fixing blocks 6 of the conducting bars 3 housed in a box are immobilized in abutment against the beam 8, by the beam 9, under the action of restoring the profiled strips 7 mechanically tensioned by a wedge system.
  • an inlet orifice is provided for a mechanical tensioning corner 19 at each lateral distribution opening 4 and here through the hatch 16 for closing this opening.
  • Each corner entry orifice is here disposed at the level of the area between the beam 9 and a part close to a bar fixing block 6, so as to allow a spacing of this beam relative to this fixing block when a corner 19 of suitable dimensions is force-fitted between them consequently causing the desired transverse tensioning of the profiled strips 7 of the box considered and the forced immobilization of the beams 8, 9 relative to each other.
  • the outer part of a corner 19 is preferably provided to serve as a polarizing device for any junction box that is just connected at the distribution opening where it is located.
  • This is in particular intended to prohibit the installation of boxes other than those which are capable of being connected to the pipeline in question, when the latter comprises one or more specialized connections, for example delivering specific voltages or intended to serve equipment. specific to an installation.
  • a polarization for example of the male-female type, allows the installation of a compatible box and prohibits any mounting of a different box.
