Description

  • L'invention est relative à un disjoncteur différentiel unipolaire et neutre selon le préambule de la revendication 1 . The invention relates to a unipolar neutral differential circuit breaker according to the preamble of claim 1.
  • Le document DE-C-1.169.015 décrit un disjoncteur différentiel du genre mentionné dans lequel un bloc différentiel, contenant un transformateur différentiel et un relais, est accolé à un bloc disjoncteur. DE-C-1169015 describes a paper GFCI of the type mentioned wherein a differential block, which contains a differential transformer and a relay is attached to a circuit breaker unit. Dans l'exemple décrit et représenté aux figures le bloc différentiel contient un circuit avec des contacts d'interruption et la liaison électrique entre les deux blocs se résume à deux conducteurs traversant la paroi de séparation des deux blocs accolés. In the example described and shown in FIGS differential block contains a circuit with the switch contacts and the electrical connection between the two blocks is to just two conductors passing through the wall separating the two adjoining blocks. La possibilité de disposer l'ensemble des contacts dans le bloc disjoncteur est simplement évoquée, mais le mode de réalisation n'est pas précisé ni représenté sur les figures. The availability of all contacts in the block CB is merely mentioned, but the embodiment is not specified or shown in FIGS. L'architecture du disjoncteur décrit s'oppose à des connexions simples, n'impliquant pas des mesures d'isolement spéciales. The architecture of the circuit breaker described opposes simple connections, not involving special isolation measures.
  • Le document EP-A 0 103 167 décrit un disjoncteur différentiel à deux compartiments distincts, l'un de logement du circuit de phase et l'autre du circuit de neutre. EP-A 0,103,167 discloses a circuit interrupter two separate compartments, one housing the phase circuit and the other of the neutral circuit. Dans le compartiment de phase est logé le contact de test de la partie différentielle, tandis que le transformateur différentiel et le relais associé sont disposés dans le compartiment de neutre. In the phase compartment housing the test contact of the differential portion, while the differential transformer and associated relay are disposed in the neutral compartment. Le disjoncteur différentiel n'est pas modulaire et il ne peut être réalisé à partir d'un disjoncteur standard. The GFCI is not modular and can not be made from a standard circuit breaker.
  • Le document FR-A 2 437 692 est relatif à un disjoncteur différentiel constitué par l'assemblage d'un disjoncteur bipolaire standard à boîtier moulé miniature, et d'un bloc différentiel de même profil. The document FR-A 2437692 relates to a differential circuit breaker formed by assembly of a standard bipolar miniature circuit breaker with molded case and a differential block of the same profile. Cet assemblage est réalisé par l'installateur ou le distributeur dont le stock peut ainsi être limité. This connection is made by the installer or distributor of which the stock can thus be limited. L'assemblage nécessite une connexion électrique externe et le raccordement de la charge est effectué sur des bomes du boîtier différentiel, différentes des bornes du boîtier disjoncteur utilisées normalement, en l'absence d'un bloc différentiel. The assembly requires an external electrical connection and the connection of the load is performed on the terminals of the differential housing, circuit breaker housing different terminals normally used in the absence of a differential block. Ces connexions compliquent la tâche de l'installateur, notamment d'un utilisateur peu averti. These connections make it difficult for the installer, including an unsophisticated user.
  • La demanderesse commercialise un disjoncteur unipolaire et neutre faisant l'objet du brevet européen EP-A 0 042 778 facilitant la tâche de l'utilisateur. The applicant markets a unipolar neutral breaker subject of EP-A 0,042,778 making it easy for the user. Dans un boîtier unique sont incorporés des contacts de coupure de phase et de neutre raccordés à deux bornes d'entrée et de sortie disposées sur les deux faces étroites opposées du boîtier. In a single housing are incorporated phase and neutral switch contacts connected to two terminals of input and output provided on both opposite narrow sides of the housing. L'utilisateur raccorde les deux conducteurs d'arrivée d'un côté de l'appareil et les deux conducteurs de départ de l'autre côté. The user connects the two incoming conductors of one side of the device and the two conductors from the other side. La coupure simultanée du circuit de neutre et du circuit de phase assure une isolation du circuit en permettant une intervention en toute sécurité. Simultaneous interruption of the neutral circuit and of the phase circuit provides isolation circuit enabling an intervention safely. Le besoin s'est fait sentir de disposer d'un disjoncteur de ce genre assurant de plus une protection différentielle contre les défauts à la terre, et la présente invention a pour but de répondre à ce besoin, par la mise en oeuvre des caractéristiques de la revendication 1. The need was felt to have a circuit breaker of this kind providing more differential protection against ground faults, and the present invention aims to meet that need, by the implementation of the characteristics of claim 1.
  • La partie disjoncteur est un disjoncteur standard, par exemple décrit dans le brevet européen précité auquel est adjoint un bloc différentiel, cette adjonction étant réalisée en usine, de manière à livrer un bloc unique comportant deux bornes d'entrée et deux bornes de sortie évitant toute erreur de connexion. The circuit-breaker portion is a standard circuit breaker, for example described in the aforesaid European patent to which is added a differential block, this addition being carried out in the factory, so as to deliver a single block having two input terminals and two output terminals avoiding Connexion error. La partie disjoncteur et la partie différentielle peuvent être intégrées côte à côte dans un même boîtier moulé dont le nombre de pas, en l'occurrence la largeur, sera supérieur à celui du bloc disjoncteur standard. The circuit-breaker portion and the differential part can be integrated side by side in a same molded housing with a number of steps, namely the width, is greater than that of the standard circuit breaker unit. Il est également possible d'utiliser un boîtier standard de disjoncteur dont l'une des faces latérales est modifiée pour permettre le passage des connexions électriques vers la partie différentielle logée dans un boîtier indépendant accolé en usine au boîtier du disjoncteur. It is also possible to use a standard circuit breaker housing whose one side face is modified to allow the passage of electrical connections to the differential part housed in a separate enclosure attached at the factory to the circuit breaker housing. En disposant la partie différentielle du côté des contacts de neutre, on facilite le raccordement électrique par les conducteurs s'étendant transversalement à l'interface entre les parties disjoncteur et différentielle. By arranging the differential part of the side of the neutral contacts, electrical connection is facilitated by the conductors extending transversely of the interface between the circuit breaker and differential parts. Les conducteurs de raccordement de phase sont disposés dans la partie supérieure du boîtier dans laquelle s'étend une partie du circuit de phase, en l'occurrence la bobine du déclencheur électromagnétique et l'extrémité de la bilame constituant le déclencheur thermique. phase connection conductors are disposed in the upper portion of the housing into which extends a portion of the phase circuit in this case the coil of the electromagnetic trip device and the end of the bimetallic strip constituting the thermal release. Ces conducteurs de raccordement passent au-dessus de la cloison isolante de séparation entre les contacts de phase et les contacts de neutre sans interférer avec le circuit de neutre. These connecting conductors pass above the insulating partition between the phase contacts and neutral contacts without interfering with the neutral circuit. Le raccordement de neutre s'opère dans la partie inférieure et ne présente aucune difficulté, les parties à raccorder étant adjacentes. The neutral connection is established in the lower part and does not present any difficulty, the parts to be connected being adjacent.
  • Selon un développement de l'invention, le raccordement de la partie différentielle de phase s'effectue d'une part au bobinage du déclencheur électromagnétique, et d'autre part à l'extrémité libre de la bilame. According to a development of the invention, the connection of the differential part of phase is carried out on the one hand the winding of the electromagnetic trip, and on the other hand at the free end of the bimetal strip. Ce raccordement limite le nombre de soudures à effectuer, le fil du bobinage pouvant par exemple être allongé pour se raccorder directement à l'enroulement primaire de la partie différentielle, la tresse soudée à l'extrémité de la bilame constituant le raccordement de l'autre extrémité de l'enroulement primaire. This connection reduces the number of welds to be made, the winding of the wire can for example be elongated to connect directly to the primary winding of the differential portion, the welded braid at the end of the bimetallic strip constituting the connection of the other end of the primary winding. L'enroulement primaire de neutre de la partie différentielle est raccordé au circuit de neutre du disjoncteur, de préférence par interruption du conducteur de liaison du contact fixe à la borne de sortie ce qui évite toute fabrication de pièces compliquées additionnelles. The primary winding neutral of the differential portion is connected to the neutral circuit breaker, preferably by interruption of the connecting line from the fixed contact to the output terminal thereby avoiding any additional manufacturing complex parts.
  • D'autres avantages et caractéristiques ressortiront plus clairement de la description qui va suivre d'un mode de mise en oeuvre de l'invention représenté aux dessins annexés, dans lesquels : Other advantages and features will become more apparent from the following description of an embodiment of the invention shown in the accompanying drawings, wherein:
    • la figure 1 est une vue schématique en élévation et en coupe suivant la ligne II de la fig. Figure 1 is a schematic view in elevation and in section along line II of FIG. 2, d'un disjoncteur selon l'invention; 2, a circuit breaker according to the invention;

    • la figure 3 représente en perspective le schéma électrique du disjoncteur. 3 shows in perspective the electrical diagram of the circuit breaker.
  • Sur les figures, un boîtier moulé 10 de forme générale parallélépipédique correspondant au système modulaire commercialement dénommé MULTI 9, est constitué par l'assemblage de deux demi-coquilles 12, 14. Sur l'une des faces latérales étroites du boîtier 10 est disposée une paire de bornes 16, 18 d'alimentation de l'appareil logé dans le boîtier 10, la face opposée de sortie portant une paire de bornes 20, 22. Les bornes opposées 16, 20 appartiennent à un circuit de phase logé à l'intérieur du boîtier 10, tandis que les bornes 18, 22 appartiennent à un circuit de neutre juxtaposé au circuit de phase. In the figures, a molded housing 10 of generally parallelepiped shape corresponding to the modular system known commercially as MULTI 9 is formed by assembling two half-shells 12, 14. On one of the narrow side faces of the housing 10 is disposed a pair of terminals 16, 18 unit's power accommodated in the housing 10, the opposite face of output carrying a pair of terminals 20, 22. the opposing terminals 16, 20 belong to a phase circuit housed inside of the housing 10, while terminals 18, 22 belong to a neutral circuit juxtaposed to the phase circuit. Une cloison intermédiaire isolante 24 est intercalée entre les coquilles 12, 14 en s'étendant parallèlement aux grandes faces latérales du boîtier 10. An insulating partition wall 24 is interposed between the shells 12, 14 extending parallel to the large side faces of the housing 10.
  • En se référant plus particulièrement à la figure 1, qui montre le circuit de neutre, on voit que la borne d'alimentation 18 porte un contact fixe 26, susceptible de coopérer avec un contact mobile de neutre 28 porté par un bras de contact isolant 30. Le contact fixe 26 est prolongé par une corne d'arc 32 s'étendant à l'intérieur d'une chambre d'extinction d'arc en regard d'une corne d'arc 34 disposée à l'arrière du contact mobile 28. La corne d'arc 34 est reliée par une tresse 36 au contact mobile 28 et se prolonge par un conducteur de raccordement 38, qui s'étend transversalement au boîtier vers une partie adjacente contenant la partie différentielle du disjoncteur décrit ci-dessous. With particular reference to Figure 1, which shows the neutral circuit, it is seen that the power supply terminal 18 carries a fixed contact 26, capable of cooperating with a movable neutral contact 28 carried by a contact arm insulator 30 . the stationary contact 26 is extended by an arc horn 32 extending within an arc extinguishing chamber opposite an arcing horn 34 disposed at the rear of the movable contact 28 . the arc runner 34 is connected by a braid 36 to the movable contact 28 and is extended by a connecting conductor 38, which extends transversely to the casing to an adjacent portion containing the differential part of the circuit breaker described below. Un deuxième conducteur de raccordement 40 parallèle au conducteur 38, est prolongé jusqu'à la borne de sortie 22. Le circuit de phase, analogue au circuit de neutre précité, comporte une borne d'entrée 16 portant un contact fixe 42 coopérant avec un contact mobile 44 porté par le bras de contact isolant 30. Le contact fixe 42 se prolonge par une corne d'arc 46, disposée en regard d'une corne d'arc 48 reliée à la borne de sortie 20. Une tresse 50 relie le contact mobile de phase 44 à l'entrée d'une bobine 52 d'un déclencheur électromagnétique dont la sortie constitue un troisième conducteur de raccordement 54 s'étendant vers la partie différentielle 64. Un quatrième conducteur de raccordement 56 en forme de tresse relie la partie différentielle à l'extrémité de la bilame 58 raccordée à la borne de sortie 20. La cloison isolante 24 sépare les contacts de neutre 26, 28 des contacts de phase 42, 44 en s'étendant dans la partie inférieure du boîtier 10. La par A second connecting conductor 40 parallel to the conductor 38, is extended to the output terminal 22. The phase circuit, similar to the neutral circuit cited above, includes an input terminal 16 carrying a fixed contact 42 cooperating with a contact mobile 44 carried by the contact arm insulator 30. the fixed contact 42 extends through an arc horn 46, arranged facing an arc horn 48 connected to the output terminal 20. a braid 50 connects contact mobile phase 44 to the input of a coil 52 of an electromagnetic trip whose output constitutes a third connection conductor 54 extending to the differential portion 64. a fourth connecting conductor 56 in the form of braid connecting part differential at the end of the bimetal 58 connected to the output terminal 20. the insulating partition 24 between the neutral contacts 26, 28 of the phase contacts 42, 44 extending in the lower housing portion 10. the by tie supérieure du boîtier 10 contient le déclencheur électromagnétique 52 ainsi que le mécanisme de déclenchement désigné par le repère général 60 qui comprend une manette de commande manuelle 62. Le déclencheur électromagnétique 52, dans la partie supérieure du boîtier 10, chevauche la cloison intermédiaire 24 et occupe l'espace au-dessus des contacts de phase et de neutre. upper tie of the housing 10 contains the electromagnetic trip 52 and the trigger mechanism designated by the general reference 60 which comprises a manual control switch 62. The electromagnetic trip device 52 in the upper housing portion 10 overlaps the intermediate wall 24 and occupies the space above the phase contacts and neutral.
  • Le disjoncteur susmentionné est décrit en détail dans le brevet européen précité, à l'exception des conducteurs de raccordement 38, 40, 54, 56, et il suffit de rappeler que les contacts de neutre 26, 28 et de phase 42, 44 sont toujours dans la même position fermée ou ouverte en étant commandés par un même mécanisme 60. Seul le circuit de phase comporte des déclencheurs. The aforementioned circuit breaker is described in detail in the European patent cited above, with the exception of the connecting conductors 38, 40, 54, 56, and suffice it to recall that the neutral contacts 26, 28 and phase 42, 44 are always in the same closed or open position being controlled by the same mechanism 60. Only the phase circuit comprises triggers. La partie différentielle 64 du boîtier 10, adjacente au circuit de neutre, contient les éléments assurant la protection différentielle, en l'occurrence le déclenchement du mécanisme 60 lors d'un défaut à la terre. The differential portion 64 of the housing 10 adjacent to the neutral circuit, contains the elements ensuring the differential protection, in this case the tripping of the mechanism 60 during a ground fault.
  • La partie différentielle 64 contient un transformateur différentiel torique 66 portant des enroulements primaires de neutre 68 et de phase 70 reliés respectivement aux conducteurs de raccordement 38, 40 et 54, 56. Le transformateur différentiel 66 porte un enroulement secondaire 72 alimentant un relais polarisé 74. Le relais polarisé 74 est relié par des liaisons mécaniques 76 au mécanisme 60 pour transmettre d'une part à ce mécanisme un ordre de déclenchement, et d'autre part une action de réarmement du relais 74 après une manoeuvre de déclenchement. Differential portion 64 contains a differential toroidal transformer 66 with primary windings 68 and a neutral phase 70 respectively connected to the connecting conductors 38, 40 and 54, 56. The differential transformer 66 carries a secondary winding 72 feeding a polarized relay 74. the polarized relay 74 is connected by mechanical links 76 to the mechanism 60 for transmitting a part in this mechanism a tripping order, and secondly a relay reset action 74 after an opening operation. De tels blocs différentiels sont bien connus des spécialistes et par exemple décrits dans le brevet français précité. Such differential blocks are known in the art and for example described in the aforementioned French patent. Un défaut à la terre se traduit par un déséquilibre entre les courants parcourant les enroulements primaires 68, 70 qui induit un courant secondaire dans l'enroulement 72 actionnant le relais 74. La partie différentielle 64 comprend bien entendu un circuit test bien connu des spécialistes. An earth fault results in an imbalance between the currents flowing through the primary windings 68, 70 which induces a secondary current in the winding 72 actuating the relay 74. The differential portion 64 includes a test circuit course, well known to specialists.
  • En disposant la partie différentielle 64 du côté des contacts de neutre 26, 28 les conducteurs de raccordement de neutre 38, 40 peuvent être disposés dans la partie inférieure du boîtier 10, tandis que les conducteurs de raccordement de phase 54, 56 passent au-dessus de la cloison 24 vers la partie différentielle 64 sans interférer avec le circuit de neutre. By disposing the differential portion 64 of the neutral contacts side 26, 28 neutral connection of the conductors 38, 40 may be disposed in the lower housing part 10, while phase connecting conductors 54, 56 pass over of the partition 24 to the differential portion 64 without interfering with the neutral circuit. On comprend que le disjoncteur différentiel unipolaire et neutre selon l'invention peut être réalisé par des éléments standard d'un disjoncteur unipolaire et neutre et d'un bloc différentiel, seules certaines parties secondaires, notamment la corne d'arc 34 et les conducteurs de raccordement 40, 56 étant remplacées par des pièces différentes. It is understood that the unipolar neutral differential circuit breaker according to the invention can be achieved by standard elements of a unipolar and neutral circuit breaker and a differential block, only some abutments, in particular the arc horn 34 and the conductors connection 40, 56 being replaced with different parts. Ce remplacement s'effectuant en usine ne pose aucun problème et l'appareil livré au client s'utilise comme tout disjoncteur normal en raccordant les circuits d'entrée et de sortie aux bornes 16, 18, 20, 22. This replacement is performing factory is no problem and the unit delivered to the customer is used like any normal circuit breaker by connecting the input and output circuits to the terminals 16, 18, 20, 22.
  • La partie disjoncteur et la partie différentielle 64 peuvent être logées dans un même boîtier 10 ou éventuellement être disposées dans des boîtiers séparés dont les parois latérales sont accolées lors du montage. The circuit-breaker portion and the differential portion 64 can be accommodated in a single housing 10 or may be disposed in separate housings which are joined side walls during assembly. Ces parois latérales comprennent bien entendu des orifices de passage des connexions électriques 38, 40, 54, 56 et des liaisons mécaniques 76. Said side walls comprise course of the passage openings of the electrical connections 38, 40, 54, 56 and mechanical connections 76.
