Description

DISPOSITIF POUR LE COUPLAGE, AVEC ISOLATION GALVANIQUE- DE TYPE "A COUPURE CERTAINE".DEVICE FOR COUPLING, WITH GALVANIC INSULATION - OF THE "CERTAIN CUT" TYPE.
La présente invention concerne un dispositif pour le couplage, avec isolation galvanique, de type "à coupure certaine" de deux circuits électriques.The present invention relates to a device for coupling, with galvanic isolation, of the "certain cut" type of two electrical circuits.
Elle s'applique notamment, mais non exclusivement, à la réalisation de couplages pour la transmission par courants porteurs de signaux à fréquence élevée (moyenne ou haute fréquence), entre plusieurs réseaux de distribution de courant électrique éventuellement indépendants les uns des autres : Grâce à ces couplages, il devient possible d'organiser des échanges d'informations entre des modules d'émission et/ou réception connectés en des points quelconques de réseaux différents.It applies in particular, but not exclusively, to the production of couplings for the transmission by currents carrying high frequency signals (medium or high frequency), between several electric current distribution networks possibly independent of each other: Thanks to these couplings, it becomes possible to organize exchanges of information between transmission and / or reception modules connected at any point on different networks.
En particulier, l'invention pourra être utilisée dans un dispositif servant à effectuer la commande et la surveillance à distance des ampoules d'un réseau d'éclairage public, tel que celui qui est décrit dans le brevet FR No 95 05748 du 12 mai 1995 déposé au nom du Demandeur.In particular, the invention may be used in a device used to remotely control and monitor the bulbs of a public lighting network, such as that described in patent FR No. 95 05748 of May 12, 1995 filed in the name of the Applicant.
On sait que ce dispositif fait intervenir, à proximité de chacune des lampes à décharge équipant les candélabres, un moyen d'émission/réception par courant porteur de messages véhiculés par les lignes électriques d'alimentation de ces candélabres, ces messages provenant ou étant transmis à destination des moyens d'émission/réception associés à d'autres candélabres et/ou d'un poste central de contrôle et de commande. Les moyens d'émission/réception associés à une lampe sont couplés, d'une part, à un dispositif de commande d'allumage et d'extinction de la lampe, en fonction de consignes émises par le poste central et, d'autre part, à un circuit de détection des défaillances de la lampe qui élabore s'il y a lieu, un signal de défaillances à destination du poste central.We know that this device involves, near each of the discharge lamps fitted to the candelabra, a means of transmission / reception by current carrying messages conveyed by the power supply lines of these candelabras, these messages coming from or being transmitted. intended for transmission / reception means associated with other candelabras and / or a central control and command station. The transmission / reception means associated with a lamp are coupled, on the one hand, to a device for controlling the switching on and off of the lamp, according to instructions issued by the central station and, on the other hand , to a lamp fault detection circuit which generates, if necessary, a fault signal intended for the central station.
Le réseau électrique destiné à assurer l'alimentation des candélabres fait habituellement intervenir au moins un poste électrique de transformation permettant de transformer le courant électrique haute tension qu'il reçoit en courant électrique triphasé basse tension destiné à alimenter un ensemble d'armoires de distribution électrique pour parties affectées à l'éclairage public. Chaque armoire de distribution pour l'éclairage reçoit en entrée le courant électrique triphasé et alimente une série de lignes électriques en basse tension monophasée. Chacune de ces lignes assure l'alimentation d'une pluralité de candélabres successifs équipés conformément au dispositif selon l'invention.The electrical network intended to supply the candelabras usually involves at least one electrical transformer station making it possible to transform the high voltage electrical current which it receives into three-phase low voltage electrical current intended to supply a set of electrical distribution cabinets for parts assigned to public lighting. Each distribution cabinet for lighting receives three-phase electrical current as input and supplies a series of low-voltage single-phase power lines. Each of these lines supplies a plurality of successive candelabras equipped in accordance with the device according to the invention.
Lorsque ce réseau électrique est complexe et comprend plusieurs postes de transformation reliés chacun à une pluralité d'armoires électriques, les lignes électriques alimentées par des postes de transformation différents sont isolées les unes des autres vis-à-vis des courants haute fréquence et ne peuvent pas communiquer les unes avec les autres par courant porteur.When this electrical network is complex and includes several transformer stations each connected to a plurality of electrical cabinets, the power lines supplied by different transformer stations are isolated from each other from high frequency currents and cannot not communicate with each other by carrier current.
Pour pouvoir assurer une telle communication entre deux lignes alimentées par des postes de transformation différents, il est alors nécessaire de prévoir un dispositif de couplage apte à assurer une transmission des signaux haute fréquence entre ces deux lignes tout en garantissant une isolation parfaite pour les courants basse fréquence véhiculés par les deux lignes.To be able to ensure such communication between two lines supplied by different transformer stations, it is then necessary to provide a coupling device capable of ensuring transmission of high frequency signals between these two lines while guaranteeing perfect isolation for low currents. frequency carried by the two lines.
Or, il s'avère que compte tenu des niveaux de tensions véhiculées par ces lignes et des risques encourus par les opérateurs chargés de l'installation et de la maintenance de ces dispositifs de couplage (courts-circuits - électrocution - chocs électriques) il est souhaitable que les conducteurs électriques de liaison connectés aux deux lignes soient séparés les uns des autres de manière à garantir une isolation suffisante, et à faciliter l'identification de ces conducteurs et donc à supprimer tout risque de confusion entre ces derniers.However, it turns out that taking into account the levels of tension carried by these lines and the risks run by the operators responsible for the installation and the maintenance of these coupling devices (short circuits - electrocution - electric shocks) it is desirable that the electrical connecting conductors connected to the two lines are separated from each other so as to guarantee sufficient insulation, and to facilitate identification of these conductors and therefore eliminate any risk of confusion between them.
Toutefois, ces différents problèmes subsistent au voisinage des dispositifs de couplage vers lesquels convergent les conducteurs électriques de liaison.However, these various problems remain in the vicinity of the coupling devices towards which the electrical connection conductors converge.
L'invention a donc plus particulièrement pour but de supprimer ces inconvénients et à résoudre ces problèmes grâce à des dispositifs de couplage spécialement conçus pour respecter ces exigences de sécurité.The invention therefore more particularly aims to eliminate these drawbacks and to solve these problems by means of coupling devices specially designed to meet these safety requirements.
Elle propose donc à cet effet un dispositif de couplage électromagnétique comprenant deux circuits séparés pouvant constituer alternativement un circuit primaire et/ou un circuit secondaire, ces deux circuits étant séparés l'un de l'autre par une matière électriquement isolante au travers de laquelle s'effectue le couplage.To this end, it therefore proposes an electromagnetic coupling device comprising two separate circuits which may alternately constitute a primary circuit and / or a secondary circuit, these two circuits being separated from each other by an electrically insulating material through which s 'performs the pairing.
Selon l'invention, ce dispositif est caractérisé en ce que ladite matière isolante est optiquement transparente de manière à ce que l'on puisse constater visuellement la séparation entre les deux circuits.According to the invention, this device is characterized in that said insulating material is optically transparent so that the separation between the two circuits can be seen visually.
Ainsi, ladite matière isolante pourra consister en du verre ou en une matière plastique transparente présentant deux faces parallèles opposées contre lesquelles sont disposés les deux circuits du dispositif de couplage.Thus, said insulating material may consist of glass or of a transparent plastic material having two opposite parallel faces against which the two circuits of the coupling device are arranged.
Avantageusement, ce dispositif de couplage pourra être de type électromagnétique et comprendre deux enroulements (un par circuit) accordés à la fréquence des signaux haute ou moyenne fréquence à transmettre. Chacun de ces enroulements pourra être inclus dans un circuit de filtrage passe haut ou passe bande, présentant une impédance minimum à la fréquence des susdits signaux et une impédance maximale à la fréquence du courant alternatif des lignes auxquelles ce circuit est connecté.Advantageously, this coupling device may be of the electromagnetic type and comprise two windings (one per circuit) tuned to the frequency of the high or medium frequency signals to be transmitted. Each of these windings may be included in a high pass or band pass filter circuit, having a minimum impedance at the frequency of the above signals and a maximum impedance at the frequency of the alternating current of the lines to which this circuit is connected.

La figure 5 est une coupe schématique d'un deuxième mode d'exécution du dispositif.Figure 5 is a schematic section of a second embodiment of the device.
Tel que représenté sur la figure 1, le réseau comprend deux postes électriques indépendants 1, 2 permettant chacun de transformer l'électricité en haute tension qu'ils reçoivent, en un courant triphasé basse tension (220 V). Ces postes 1, 2 servent à alimenter deux ensembles d'armoires de distribution électrique 6 , 62 - 6'ι, 6'2 dont certaines (par exemple les armoires 6^ et 6'2) sont affectées à l'éclairage public.As shown in Figure 1, the network includes two independent electrical stations 1, 2 each for transforming the high voltage electricity they receive, into a low-voltage three-phase current (220 V). These stations 1, 2 are used to supply two sets of electrical distribution cabinets 6, 6 2 - 6'ι, 6 ' 2 , some of which (for example cabinets 6 ^ and 6' 2 ) are used for public lighting.
L'armoire 6ι reçoit en entrée le courant basse tension triphasée, et alimente un ensemble de lignes électriques 7 en basse tension monophasée. Chacune de ces lignes 7 comprend deux fils 15, 16 permettant d'alimenter une pluralité de lampes à décharge associées chacune à un dispositif de commande et de surveillance 10.The cabinet 6ι receives the low-voltage three-phase current as an input, and supplies a set of power lines 7 with low single-phase voltage. Each of these lines 7 comprise two wires 15, 16 making it possible to supply a plurality of discharge lamps each associated with a control and monitoring device 10.
Ce dispositif 10 est conçu pour émettre et recevoir des informations par courant porteur, en modulation de phase, par exemple à une fréquence de 132 KHz, via les lignes 7 du réseau de distribution électrique, pour communiquer avec un poste central 3 connecté ici à l'une des lignes d'une autre armoire de distribution électrique 6'2 qui alimente des lignes électriques 17 indépendantes des lignes 7. A cet effet, le poste central 3 est équipé d'un calculateur 5, connecté à la ligne 17, par l'intermédiaire d'un module d'interface 4.This device 10 is designed to transmit and receive information by carrier current, 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. For this purpose, the central station 3 is equipped with a computer 5, connected to line 17, by the through an interface module 4.
Comme précédemment mentionné, l'invention a pour but de permettre notamment la communication entre le poste central 3 et les dispositifs de commande et de surveillance 10 associés aux lampes à décharge alimentées par les lignes 7 et 17 connectées aux armoires de distribution χ et 6'2. A cet effet, elle prévoit d'effectuer un couplage reliant les conducteurs 15, 16, de l'une des lignes 7 aux conducteurs de l'une des lignes 17 raccordés à l'armoire de distribution 2.As previously mentioned, the invention aims in particular to allow communication between the central station 3 and the control and monitoring devices 10 associated with the discharge lamps supplied by the lines 7 and 17 connected to the distribution cabinets χ and 6 ' 2 . To this end, it plans to carry out 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.
Ce couplage est assuré par un coupleur 18 représenté schématiquement sur la figure 1 par un quadripôle connecté par deux de ses bornes h B2 aux deux conducteurs 15, 16, et par ses deux autres bornes B3, B4 aux conducteurs 20, 21 de la ligne 17.This coupling is ensured by a coupler 18 shown diagrammatically in FIG. 1 by a quadrupole connected by two of its terminals h B 2 to the two conductors 15, 16, and by its two other terminals B 3 , B 4 to the conductors 20, 21 of line 17.
Dans l'exemple représenté sur les figures 2 à 4, ce coupleur fait intervenir deux bobines Ei, E2 disposées en regard l'une de l'autre, chacune de ces bobines Ei, E2 étant connectée aux deux conducteurs 15, 16 - 20, 21 de la ligne correspondante par l'intermédiaire de deux conducteurs de liaison et d'un circuit de filtrage comprenant un ensemble inductance Li, L2/condensateur en série Ci, C et un condensateur en parallèle C'i, C . Ce circuit constitue, avec la bobine Ei, E2, un filtre passe bande dont la bande passante est centrée sur la fréquence des signaux échangés entre le poste central et les dispositifs de commande et de surveillance des lampes 10 (par exemple 130 KHz).In the example shown in FIGS. 2 to 4, this coupler involves two coils Ei, E 2 arranged opposite one another, each of these coils Ei, E 2 being connected to the two conductors 15, 16 - 20, 21 of the corresponding line via two connecting conductors and a filtering circuit comprising an inductance Li, L 2 / capacitor in series Ci, C and a capacitor in parallel C'i, C. This circuit constitutes, with the coil Ei, E 2 , a bandpass filter whose bandwidth is centered on the frequency of the signals exchanged between the central station and the lamp control and monitoring devices 10 (for example 130 KHz).
Dans cet exemple, chacune des bobines Ei, E2 est réalisée par enroulement d'un fil conducteur autour d'un noyau de ferrite Ni, N2. Les deux bobines E1? E2 sont axées parallèlement l'une par rapport à l'autre et sont respectivement montées sur deux disques de circuit imprimé coaxiaux D1; D2 axés peφendiculairement aux bobines E1; E . Chacun de ces circuits imprimés Di, D2 porte l'inductance et les deux condensateurs du circuit de filtrage.In this example, each of the coils Ei, E 2 is produced by winding a conductive wire around a ferrite core Ni, N 2 . The two coils E 1? E 2 are oriented parallel to each other and are respectively mounted on two coaxial printed circuit discs D 1; D 2 centered peφendicular to the coils E 1; E. Each of these printed circuits Di, D 2 carries the inductance and the two capacitors of the filtering circuit.
Les deux disques de circuits imprimés Di, D2, munis de leurs composants, sont logés dans deux manchons tabulaires Mi, M2 par exemple en chlorure de polyvinyle (PVC) disposés coaxialement l'un en regard de l'autre et séparés l'un de l'autre par une rondelle épaisse R réalisée en une matière transparente électriquement isolante.The two discs of printed circuits Di, D 2 , provided with their components, are housed in two tabular sleeves Mi, M 2 for example made of polyvinyl chloride (PVC) arranged coaxially opposite one another and separated from each other. one from the other by a thick washer R made of an electrically insulating transparent material.
La fixation de l'ensemble est assurée :The assembly is ensured:
- d'une part, par collage des bords en regard des manchons M1? M2 sur les faces opposées de la rondelle R, et- on the one hand, by gluing the edges opposite the sleeves M 1? M 2 on the opposite faces of the washer R, and
- d'autre part, par des vis Vl5 V2 en matière électriquement isolante qui s'étendent axialement dans les manchons Mi, M2 en passant par des orifices coaxiaux prévus dans la rondelle R et dans les circuits imprimés- on the other hand, by screws V 15 V 2 of electrically insulating material which extend axially in the sleeves Mi, M 2 passing through coaxial orifices provided in the washer R and in the printed circuits
Dh D2 ; les têtes de ces vis Vl5 V2 viennent en appui sur la face extérieure de l'un des circuits imprimés D2, tandis que des écrous vissés sur les extrémités filetées des vis viennent porter sur la face extérieure de l'autre circuit imprimé Di, l'écartement entre les circuits imprimés et la rondelle R est imposé par des entretoises tubulaires ET par lesquelles passent les visD h D 2 ; the heads of these screws V l5 V 2 come to bear on the external face of one of the printed circuits D 2 , while nuts screwed onto the threaded ends of the screws come to bear on the external face of the other printed circuit Di , the distance between the printed circuits and the washer R is imposed by tubular spacers ET through which the screws pass
Vi, V2. Du côté opposé à la rondelle R, le volume délimité par le circuit imprimé D1; D2 et le manchon tubulaire Mi, M2 permet le passage des fils de liaison FLi, FL2. Ce volume peut être comblé par une matière d'enrobage garantissant l'étanchéité de l'ensemble.Vi, V 2 . On the side opposite to the washer R, the volume delimited by the printed circuit D 1; D 2 and the tubular sleeve Mi, M 2 allows the passage of the connecting wires FLi, FL 2 . This volume can be filled with a coating material ensuring the tightness of the assembly.
Une fois monté, le dispositif de couplage présente une forme cylindrique présentant deux portions opaques Pi, P2 contenant chacune un circuit de couplage respectif. Ces deux portions Pi, P2 sont séparées par une portion transparente P3 de plus grand diamètre constituée par la rondelle R.Once mounted, the coupling device has a cylindrical shape having two opaque portions Pi, P 2 each containing a respective coupling circuit. These two portions Pi, P 2 are separated by a transparent portion P 3 of larger diameter constituted by the washer R.
Ainsi, un opérateur pourra vérifier visuellement l'isolation entre les deux circuits de couplage. En séparant physiquement les conducteurs de liaison respectivement connectés aux deux extrémités des dispositifs de couplage, on écarte en outre toute possibilité d'erreur de câblage et on garantit une parfaite isolation entre ces conducteurs.Thus, an operator can visually check the insulation between the two coupling circuits. By physically separating the connection conductors respectively connected to the two ends of the coupling devices, it also eliminates any possibility of wiring error and guarantees perfect insulation between these conductors.
Dans l'exemple représenté sur la figure 5, les bobines comprennent chacune un enroulement E'i, E'2 réalisé autour du noyau central de pots de ferrite PFi, PF2 de section en forme de E.In the example shown in FIG. 5, the coils each comprise a winding E'i, E ' 2 produced around the central core of ferrite pots PFi, PF 2 of E-shaped section.
Les deux pots de ferrite PFi, PF2 sont disposés coaxialement en regard l'un de l'autre du côté opposé à leurs fonds FDi, FD2, et sont séparés l'un de l'autre par un disque en matière transparente DT.The two ferrite pots PFi, PF 2 are arranged coaxially opposite one another on the side opposite their bottoms FDi, FD 2 , and are separated from each other by a disc made of transparent material DT.
La fixation de l'ensemble est obtenu par collage des faces radiales des deux pots sur les deux faces parallèles opposées du disque.The assembly is obtained by bonding the radial faces of the two pots to the two opposite parallel faces of the disc.
Bien entendu, l'invention ne se limite pas à la commande et à la surveillance d'un éclairage public. Elle peut être utilisée dans de nombreux circuits à courant porteur, notamment entre les postes d'émission et/ou de réception et les Hgnes de distribution de courant électrique utilisées en tant que lignes de transmission. Of course, the invention is not limited to the control and monitoring of public lighting. It can be used in many carrier current circuits, in particular between transmitting and / or receiving stations and Electric power distribution lines used as transmission lines.
