Description

L'invention concerne un relais de commande associé à un capteur extérieur de mesure, le relais comprenant un boîtier isolant renfermant un circuit de traitement destiné à recevoir le signal de mesure issu du capteur, et à délivrer un signal de sortie, notamment de déclenchement et/ou de signalisation, en cas de dépassement d'un seuil prédéterminé.The invention relates to a control relay associated with an external measurement sensor, the relay comprising an insulating housing containing a processing circuit intended to receive the measurement signal coming from the sensor, and to deliver an output signal, in particular of triggering and / or signaling, if a predetermined threshold is exceeded.

Le capteur peut être constitué par un tore fermé ou ouvrant, lequel est généralement installé sur un rail support ou une platine au moyen d'un organe de fixation auxiliaire. La liaison entre relais et tore est essentiellement électrique grâce à un fil blindé ou une ligne spéciale de connexion. Pour certaines applications, la continuité de la liaison électrique entre le tore et le relais doit être vérifiée par un dispositif électronique d'auto-contrôle intégré dans le circuit de traitement.The sensor can consist of a closed or opening toroid, which is generally installed on a support rail or a plate by means of an auxiliary fixing member. The connection between relay and toroid is essentially electrical thanks to a shielded wire or a special connection line. For certain applications, the continuity of the electrical connection between the toroid and the relay must be checked by an electronic self-checking device integrated in the processing circuit.

Il est également connu d'incorporer le tore à l'intérieur du boîtier d'un relais différentiel. Un tel relais à tore intégré ne convient pas pour toutes les installations électriques.It is also known to incorporate the toroid inside the case of a differential relay. Such a built-in toroid relay is not suitable for all electrical installations.

L'objet de l'invention consiste à simplifier le raccordement d'un capteur de mesure à un relais de commande.The object of the invention is to simplify the connection of a measurement sensor to a control relay.

Le relais selon l'invention est caractérisé en ce que le boîtier du relais comporte un premier connecteur et un deuxième connecteur de structures identiques, reliés électriquement au circuit de traitement du relais, et situés en des endroits distincts, notamment de la face latérale et du socle de fixation du boîtier, et que le capteur est équipé d'un troisième connecteur conjugué, lequel est agencé pour autoriser le montage et la connexion électrique du capteur au relais par embrochage du troisième connecteur dans l'un quelconque des premier ou deuxième connecteurs du boîtier.The relay according to the invention is characterized in that the relay housing comprises a first connector and a second connector of identical structures, electrically connected to the relay processing circuit, and located in separate locations, in particular on the side face and the base for fixing the housing, and that the sensor is equipped with a third conjugate connector, which is arranged to authorize the mounting and the electrical connection of the sensor to the relay by plugging in the third connector into any of the first or second connectors of the housing.

Le troisième connecteur d'embrochage du capteur est associé à un organe d'accouplement susceptible de s'engager dans une glissière de retenue pour assurer l'accrochage mécanique du capteur sur le boîtier.The third sensor plug-in connector is associated with a coupling member capable of engaging in a retaining slide to ensure mechanical attachment of the sensor to the housing.

Le changement de position du capteur par rapport au relais, notamment par embrochage sur le côté et à l'arrière du boîtier, dépend de l'emplacement des conducteurs de raccordement, ou du jeu de barre d'alimentation.The change of position of the sensor with respect to the relay, in particular by plugging in on the side and rear of the box, depends on the location of the connection conductors, or on the supply busbar.

Les autres assemblages traditionnels du capteur séparé restent possibles grâce à une embase de fixation conformée dans le bloc d'enrobage du capteur.The other traditional assemblies of the separate sensor remain possible thanks to a fixing base shaped in the sensor coating block.

Le capteur peut être formé par un tore homopolaire, ou tout autre détecteur de courant ou de tension.The sensor can be formed by a zero sequence toroid, or any other current or voltage detector.

D'autres avantages et caractéristiques de l'invention ressortiront de la description qui va suivre d'un mode de réalisation donné à titre d'exemple non limitatif, et représenté aux dessins annexés, dans lesquels:

Other advantages and characteristics of the invention will emerge from the description which follows of an embodiment given by way of nonlimiting example, and represented in the appended drawings, in which:
  • - Figure 1 shows a perspective view of the differential relay according to the invention with the two locations of the toroid in the withdrawn position;

Sur les figures 1 et 2, un relais 10 de commande, notamment à protection différentielle, est associé à un capteur 11 de mesure formé par un tore 12 à transformateur totalisateur, capable de détecter un courant différentiel résiduel. Le relais 10 est logé dans un boîtier 14 isolant modulaire ayant un socle de fixation 16 facilement adaptable par encliquetage à un rail support 18, ou à tout autre organe de montage. Le transformateur totalisateur du tore 12 comporte un circuit magnétique sur lequel est bobiné un enroulement de mesure (non représenté), l'ensemble étant noyé dans un bloc d'enrobage 20 en matériau isolant moulé. Le tore 12 est traversé par les conducteurs actifs (non représentés) d'une installation ou d'un réseau à protéger, et l'enroulement de mesure du transformateur est le siège d'un signal différentiel engendré lors de l'apparition d'un défaut d'isolement par rapport à la terre. Le signal différentiel de sortie du capteur 11 est appliqué à un circuit de traitement (non représenté) agencé dans le boîtier 14, ledit circuit étant capable de délivrer un ordre électrique de déclenchement ou de signalisation lorsque le seuil de déclenchement différentiel est dépassé. Le relais 10 peut piloter une bobine d'un mécanisme de commande d'un disjoncteur ou d'un contacteur.In FIGS. 1 and 2, a control relay 10, in particular with differential protection, is associated with a measurement sensor 11 formed by a toroid 12 with totalizing transformer, capable of detecting a residual differential current. The relay 10 is housed in a modular insulating housing 14 having a mounting base 16 easily adaptable by snap-fastening to a support rail 18, or to any other mounting member. The totalizing transformer of the torus 12 comprises a magnetic circuit on which is wound a measurement winding (not shown), the assembly being embedded in a coating block 20 of molded insulating material. The toroid 12 is crossed by the active conductors (not shown) of an installation or of a network to be protected, and the measurement winding of the transformer is the seat of a differential signal generated during the appearance of a insulation fault with respect to earth. The differential output signal from the sensor 11 is applied to a processing circuit (not shown) arranged in the housing 14, said circuit being capable of issuing an electrical tripping or signaling order when the differential tripping threshold is exceeded. Relay 10 can drive a coil of a circuit breaker or contactor control mechanism.

Le bloc d'enrobage 20 du tore 12 comporte un connecteur mâle 22 d'embrochage ayant une pluralité de broches 23 de connexion raccordées à l'enroulement de mesure. Le connecteur mâle 22 du tore 12 peut être enfiché dans l'un des connecteurs femelles 24,26 de structures identiques, situés en des endroits prédéterminés du relais 10. Le premier connecteur femelle 24 est ménagé sur l'une des faces latérales 27 du boîtier 14 isolant, tandis que le deuxième connecteur femelle 26 est agencé à la partie supérieure du socle de fixation 16. Il est clair que le dispositif d'embrochage peut être inversé, en prévoyant le connecteur femelle sur le tore 12, et les connecteurs mâles sur le relais 10. Les deux connecteurs femelles 24,26 sont connectés électriquement au circuit de traitement du relais 10.The coating block 20 of the torus 12 comprises a male connector 22 for plugging in having a plurality of connection pins 23 connected to the measurement winding. The male connector 22 of the torus 12 can be inserted into one of the female connectors 24, 26 of identical structures, located at predetermined locations of the relay 10. The first female connector 24 is formed on one of the lateral faces 27 of the housing 14 insulator, while the second female connector 26 is arranged at the upper part of the mounting base 16. It is clear that the racking device can be reversed, by providing the female connector on the toroid 12, and the male connectors on the relay 10. The two female connectors 24, 26 are electrically connected to the processing circuit of the relay 10.

Le tore 12 peut ainsi être montré au choix sur le côté ou à l'arrière du relais 10 (voir figure 1) en fonction de la position des conducteurs actifs traversant le tore. Dans un tableau électrique, l'implantation des conducteurs de raccordement et de jeu de barres d'alimentation est parfaitement définie, et la possibilité d'adaptation de l'emplacement du tore 12 sur le relais 10 facilite le montage et le câblage du tableau.The toroid 12 can thus be shown as desired on the side or at the rear of the relay 10 (see FIG. 1) as a function of the position of the active conductors passing through the torus. In an electrical panel, the location of the connection and power busbar conductors is perfectly defined, and the possibility of adapting the location of the toroid 12 on the relay 10 facilitates the assembly and wiring of the panel.

L'embrochage du tore 12 sur le relais 10 selon les figures 1 et 2 ne nécessite aucune liaison électrique souple, et le maintien mécanique du tore 12 s'effectue par accrochage sur le boîtier 14 au moyen d'un organe d'accouplement 28 associé au connecteur mâle 22. L'organe d'accouplement 28 s'engage à cet effet dans une glissière 30,32 du boîtier 14, lors de l'insertion des broches 23 du connecteur mâle 22 dans les alvéoles de réception du connecteur femelle 24 ou 26.The plugging in of the toroid 12 on the relay 10 according to FIGS. 1 and 2 does not require any flexible electrical connection, and the mechanical maintenance of the toroid 12 is effected by attachment to the housing 14 by means of an associated coupling member 28 to the male connector 22. The coupling member 28 engages for this purpose in a slide 30, 32 of the housing 14, during the insertion of the pins 23 of the male connector 22 into the receptacles of the female connector 24 or 26.

Sur les figures 1 et 2, l'agencement du tore 12 par rapport au relais 10 est représenté dans un plan parallèle au rail support 18 pour les deux position d'embrochage. Les conducteurs actifs traversent alors verticalement le tore 12 selon une direction perpendiculaire au rail support 18.In FIGS. 1 and 2, the arrangement of the toroid 12 with respect to the relay 10 is shown in a plane parallel to the support rail 18 for the two racking-in positions. The active conductors then pass vertically through the torus 12 in a direction perpendicular to the support rail 18.

L'orientation du tore 12 sur le relais 10 peut bien entendu être modifiée en fonction de l'inclinaison des connecteurs femelles 24,26 sur le boîtier 14. Si le premier connecteur femelle 24 est orienté selon une direction verticale, c'est à dire perpendiculaire à celle représentée sur la figure 1, l'axe du tore 12 s'étend perpendiculairement au rail support 18. Lorsque le deuxième connecteur femelle 26 est vertical, l'axe du tore 12 s'étend parallèlement au rail support 18.The orientation of the toroid 12 on the relay 10 can of course be modified as a function of the inclination of the female connectors 24, 26 on the housing 14. If the first female connector 24 is oriented in a vertical direction, that is to say perpendicular to that shown in FIG. 1, the axis of the torus 12 extends perpendicular to the support rail 18. When the second female connector 26 is vertical, the axis of the torus 12 extends parallel to the support rail 18.

La figure 3 représente une vue complète en perspective du tore 12. Le bloc d'enrobage 20 est équipé en plus d'une embase 34 de fixation auxiliaire décalée angulairement, notamment à angle droit par rapport au connecteur mâle 22. Cette embase 34 permet de réaliser un montage séparé du tore 12, en le fixant directement sur le rail support 18 (figures 4 et 5) ou sur une platine 36 (figures 6 et 7).FIG. 3 represents a complete perspective view of the torus 12. The coating block 20 is equipped in addition with a base 34 for auxiliary fixing angularly offset, in particular at right angles to the male connector 22. This base 34 makes it possible to carry out a separate mounting of toroid 12, by fixing it directly on the support rail 18 (Figures 4 and 5) or on a plate 36 (Figures 6 and 7).

L'embase 34 de fixation comporte une série de rainures verticales 38 et horizontales 40 autorisant l'encliquetage d'une pièce 42 intermédiaire selon deux positions différentes. Cette pièce 42 d'adaptation est ensuite rapportée sur le rail support 18 à profil symétrique. Selon la position de la pièce 42 sur l'embase de fixation 34, le tore 12 est soit horizontal (figure 4) avec passage vertical des conducteurs actifs, soit vertical (figure 5) avec passage horizontal des conducteurs actifs.The fixing base 34 has a series of vertical 38 and horizontal 40 grooves allowing the snap-fastening of an intermediate piece 42 in two different positions. This adaptation piece 42 is then attached to the support rail 18 with a symmetrical profile. Depending on the position of the part 42 on the fixing base 34, the torus 12 is either horizontal (FIG. 4) with vertical passage of the active conductors, or vertical (FIG. 5) with horizontal passage of the active conductors.

L'embase 34 de fixation comprend en outre deux séries d'orifices 44,46 autorisant le passage de vis 48 pour le montage à plat (figure 6) ou en équerre (figure 7) du tore 12 sur la platine 36.The mounting base 34 further comprises two series of holes 44, 46 allowing the passage of screws 48 for mounting flat (FIG. 6) or at an angle (FIG. 7) of the torus 12 on the plate 36.

Dans le cas de montage séparé du tore 12 selon les figures 4 à 7, la connexion électrique avec le relais 10 s'opère au moyen d'un dispositif de connexion souple (non représenté) ayant à l'une des extrémités un connecteur femelle monté à enfichage dans le troisième connecteur mâle 22 du tore 12, et à l'extrémité opposée un autre connecteur mâle relié à une prise du courant auxiliaire (50, figure 1) du boîtier 14.In the case of separate mounting of the torus 12 according to FIGS. 4 to 7, the electrical connection with the relay 10 takes place by means of a flexible connection device (not shown) having at one end a female connector mounted plugged into the third male connector 22 of the torus 12, and at the opposite end another male connector connected to an auxiliary current socket (50, FIG. 1) of the housing 14.

L'agencement du bloc d'enrobage 20 permet de multiples possibilités de montage du capteur 11 à un relais 10, soit en version adaptable (figures 1 et 2), soit en version séparée (figures 4 à 7). Le capteur 11 peut être formé par tout autre détecteur de courant ou de tension.The arrangement of the coating block 20 allows multiple possibilities of mounting the sensor 11 to a relay 10, either in an adaptable version (Figures 1 and 2), or in a separate version (Figures 4 to 7). The sensor 11 can be formed by any other current or voltage detector.
