Definitions

  • the present invention relates to a device for the coupling, with galvanic isolation, type "cut-off" of two electrical circuits.
  • this device involves, in the vicinity of each of the discharge lamps fitted to the candelabra, means for transmitting / receiving current carrying messages conveyed by the power supply lines of these candelabra, these messages from or being transmitted to the transmitting / receiving means associated with other candelabra and / or a central control and control station.
  • the transmitting / receiving means associated with a lamp are coupled, on the one hand, to an ignition control device and extinguishing the lamp, according to instructions issued by the central station and on the other hand , a fault detection circuit of the lamp which prepares if necessary, a fault signal to the central station.
  • the electrical network for supplying the candelabra usually involves at least one transforming substation for transforming the high-voltage electrical current it receives into three-phase low-voltage electrical power for supplying a set of electrical distribution cabinets for parties assigned to public lighting.
  • Each distribution cabinet for lighting receives the three-phase electrical input and feeds a series of single-phase low-voltage power lines. Each of these lines provides power to a plurality of successive candelabra equipped according to the device according to the invention.
  • this electrical network is complex and comprises several transformer stations each connected to a plurality of electrical cabinets, the power lines powered by different transformer stations are isolated from each other vis-à-vis the high frequency currents and can not not communicate with each other by power line.
  • the document FR-A-2,765,735 relates to a non-contact energy transfer device for supplying electrical energy to an apparatus.
  • a small piece of thick glass is centrally located between two coils. This small central element serves only to pass an infrared optical signal for positioning.
  • the element that separates the two coils is a circular induction plate having a coating adapted to the public space and in particular non-slip and discreet.
  • the object of the invention is therefore more particularly to eliminate these drawbacks and to solve these problems by means of coupling devices specially designed to comply with these safety requirements.
  • an electromagnetic coupling device comprising two separate circuits that can constitute alternately a primary circuit and / or a secondary circuit, these two circuits being separated from one another by an electrically insulating material through which performs the coupling.
  • this device is characterized in that said insulating material is optically transparent so that the separation between the two circuits can be seen visually.
  • said insulating material may consist of glass or a transparent plastic material having two opposite parallel faces against which are arranged the two circuits of the coupling device.
  • Each of these windings may be included in a high-pass or band-pass filtering circuit, having a minimum impedance at the frequency of the said signals and a maximum impedance at the frequency of the alternating current of the lines to which this circuit is connected.
  • the network comprises two independent electrical stations 1, 2 each for transforming the high voltage electricity they receive into a three-phase low voltage (220 V). These positions 1, 2 are used to supply two sets of power distribution cabinets 6 1, June 2 to 6 '1 6' 2 some (eg cabinets and 6 1 6 '2) are assigned to public lighting .
  • the cabinet 6 1 receives the three-phase low-voltage current input, and supplies a set of single-phase low-voltage electrical lines 7.
  • Each of these lines 7 comprises two wires 15, 16 for feeding a plurality of discharge lamps each associated with a control and monitoring device 10.
  • This device 10 is designed to transmit and receive carrier current information, in phase modulation, for example at a frequency of 132 KHz, via the lines 7 of the electrical distribution network, to communicate with a central station 3 connected here to the one of the lines of another electrical distribution cabinet 6 ' 2 which supplies electrical lines 17 independent of the lines 7.
  • the central station 3 is equipped with a computer 5, connected to the line 17, by the intermediate of an interface module 4.
  • the invention is intended to allow in particular the communication between the central station 3 and the control devices 10 and associated monitoring discharge lamps supplied by the lines 7 and 17 connected to the distribution cabinets 6 1 and 6 ' 2 .
  • it provides for a coupling connecting the conductors 15, 16 of one of the lines 7 to the conductors of one of the lines 17 connected to the distribution cabinet 2.
  • This coupling is provided by a coupler 18 shown schematically on the figure 1 by a quadrupole connected by two of its terminals B 1 , B 2 to the two conductors 15, 16, and by its two other terminals B 3 , B 4 to the conductors 20, 21 of the line 17.
  • this coupler involves two coils E 1 , E 2 arranged opposite one another, each of these coils E 1 , E 2 being connected to the two conductors 15, 16 - 20, 21 of the corresponding line by the intermediate of two connecting conductors and a filter circuit comprising a set of inductance L 1 , L 2 / capacitor in series C 1 , C 2 and a capacitor in parallel C ' 1 , C' 2 .
  • This circuit constitutes, with the coil E 1 , E 2 , a band pass filter whose bandwidth is centered on the frequency of the signals exchanged between the central station and the control and monitoring devices of the lamps 10 (for example 130 KHz) .
  • each of the coils E 1 , E 2 is made by winding a conductive wire around a ferrite core N 1 , N 2 .
  • the two coils E 1 , E 2 are oriented parallel to each other and are respectively mounted on two coaxial printed circuit disks D 1 , D 2 oriented perpendicular to the coils E 1 , E 2 .
  • Each of these printed circuits D 1, D 2 carries the inductor and the two capacitors of the filter circuit.
  • the two printed circuit disks D 1 , D 2 equipped with their components, are housed in two tubular sleeves M 1 , M 2 for example polyvinyl chloride (PVC) arranged coaxially opposite one another and separated from one another by a thick washer R made of an electrically insulating transparent material.
  • PVC polyvinyl chloride
  • the volume delimited by the printed circuit D 1 , D 2 and the tubular sleeve M 1 , M 2 allows the passage of the connecting wires FL 1 , FL 2 .
  • This volume can be filled by a coating material ensuring the tightness of the assembly.
  • the coupling device has a cylindrical shape having two opaque portions P 1 , P 2 each containing a respective coupling circuit. These two portions P 1 , P 2 are separated by a transparent portion P 3 of larger diameter formed by the washer R.
  • the coils each comprise a winding E ' 1 , E' 2 formed around the central core of ferrite pots PF 1 , PF 2 section E-shaped.
  • the two ferrite pots PF 1 , PF 2 are arranged coaxially facing each other on the opposite side to their bottoms FD 1 , FD 2 , and are separated from each other by a disk of transparent material. DT.
  • Fixing the assembly is obtained by gluing the radial faces of the two pots on the two opposite parallel faces of the disk.
  • the invention is not limited to the control and monitoring of a street lighting. It can be used in many powerline circuits, especially between the transmitting and / or receiving stations and power distribution lines used as transmission lines.
