L'invention est relative à un disjoncteur différentiel unipolaire et neutre logé dans un boîtier isolant subdivisé par une paroi de séparation en deux parties adjacentes renfermant:

  • un premier compartiment disjoncteur comportant un circuit de phase ayant un contact fixe de phase,un contact mobile de phase, et un déclencheur magnétothermique à bilame et à bobine, un circuit de neutre ayant un contact fixe de neutre et un contact mobile de neutre, une première paire de bornes de phase amont et aval, une deuxième paire de bornes de neutre amont et aval, et un premier mécanisme à commande manuelle par une manette, et à commande automatique par le déclencheur magnétothermique,
  • un deuxième compartiment à protection différentiellle comprenant un transformateur différentiel à tore magnétique portant un enroulement primaire de phase, un enroulement primaire de neutre, et un enroulement secondaire de mesure associé à un relais de déclenchement coopérant avec un deuxième mécanisme déclencheur en liaison mécanique avec le premier mécanisme, et avec un circuit test à résistance d'essai, et à bouton poussoir,
  • des orifices ménagés dans la paroi de séparation pour le passage des conducteurs de raccordement autorisant l'insertion respectivement des enroulements primaires de phase et de neutre dans les circuits de phase et de neutre,
  • les bornes amont, de phase et de neutre étant disposées côte à côte sur une même face étroite du boîtier,
  • et les bornes aval de phase et de neutre étant situées côte à côte sur la face opposée du boîtier,
The invention relates to a unipolar and neutral differential circuit breaker housed in an insulating housing subdivided by a partition wall into two adjacent parts containing:
  • a first circuit breaker compartment comprising a phase circuit having a fixed phase contact, a movable phase contact, and a magnetothermal trip device with bimetallic strip and coil, a neutral circuit having a fixed neutral contact and a movable neutral contact, a first pair of upstream and downstream phase terminals, a second pair of upstream and downstream neutral terminals, and a first mechanism manually controlled by a lever, and automatically controlled by the magnetothermal release,
  • a second differential protection compartment comprising a differential transformer with magnetic core carrying a primary phase winding, a primary neutral winding, and a secondary measurement winding associated with a trigger relay cooperating with a second trigger mechanism in mechanical connection with the first mechanism, and with a test circuit with test resistance, and with push button,
  • orifices provided in the separation wall for the passage of the connection conductors allowing the insertion of the primary phase and neutral windings respectively in the phase and neutral circuits,
  • the upstream, phase and neutral terminals being placed side by side on the same narrow face of the housing,
  • and the downstream phase and neutral terminals being located side by side on the opposite face of the housing,

Un tel disjoncteur différentiel est connu du document FR-A-2. 662. 017 de la demanderesse. Les orifices de passage des conducteurs de raccordement des enroulements primaires de phase et de neutre sont situés d'un même côté du tore dans un intervalle agencé entre la borne aval de phase et la zone déchappement de la chambre d'extinction du circuit de phase. Les quatre orifices s'étendent dans un même plan perpendiculaire a la paroi de séparation, et sont décalés verticalement l'un de l'autre par des distances réduites. Un tel encombrement limité ne se prête pas à une automatisation de la connexion par soudage électrique des quatre conducteurs de raccordement aux extrémités des enroulements primaires du transformateur différentiel. Le soudage des connexions doit être fait en manuel avec apport d'étain.Il en résulte des problèmes de cadence de fabrication et des problèmes de tenue diélectrique occasionnés par le rapprochement des pièces conductrices à des potentiels différents.Such a differential circuit breaker is known from document FR-A-2. 662. 017 of the plaintiff. The passage openings of connection conductors of the primary phase and neutral windings are located on the same side of the toroid in an interval arranged between the downstream phase terminal and the exhaust zone of the extinction chamber of the phase circuit. The four openings extend in the same plane perpendicular to the partition wall, and are offset vertically from each other by reduced distances. Such limited space does not lend itself to automation of the connection by electrical welding of the four connection conductors at the ends of the primary windings of the differential transformer. Soldering of the connections must be done manually with the addition of tin. This results in production rate problems and problems with dielectric strength caused by bringing the conductive parts to different potentials.

L'objet de l'invention consiste à améliorer la tenue diélectrique d'un disjoncteur différentiel unipolaire et neutre, et à permettre le raccordement électrique du transfortmateur différentiel au moyen d'une machine de soudage automatique.The object of the invention is to improve the dielectric strength of a single-pole and neutral differential circuit breaker, and to allow the electrical connection of the differential transformer by means of an automatic welding machine.

Le disjoncteur différentiel selon l'invention est caractérisé en ce que le tore est disposé entre la première et la deuxième paires de conducteurs de raccordement, que l'insertion des enroulements primaires de phase et de neutre s'opère soit à l'amont et à l'aval, soit à l'aval et à l'amont des circuits de phase et de neutre, et que les deux extrémités du circuit test sont branchées simultanément soit à l'aval, soit à l'amont des contacts de phase et de neutre.The differential circuit breaker according to the invention is characterized in that the toroid is disposed between the first and second pairs of connection conductors, that the insertion of the primary phase and neutral windings takes place either upstream and downstream, either downstream and upstream of the phase and neutral circuits, and both ends of the test circuit are connected simultaneously either downstream or upstream of the phase and neutral.

De préférence, les quatre conducteurs de raccordement comportent des languettes saillantes en matériau conducteur, disposées en porte-à-faux, et s'étendant parallèlement entre elles selon une direction perpendiculaire à la paroi de séparation, l'extrémité de chaque languette étant dotée d'un évidement de positionnement dans lequel est insérée l'extrémité correspondante de l'enroulement primaire de phase ou de neutre. L'agencement selon l'invention permet le passage des électrodes d'une machine de soudage pour le raccordement automatique des enroulements primaires aux languettes. La tenue diélectrique est améliorée car la différence de potentiel est reportée de part et d'autre du tore.Preferably, the four connection conductors have protruding tongues of conductive material, arranged in overhang, and extending parallel to each other in a direction perpendicular to the partition wall, the end of each tongue being provided with '' a positioning recess into which the corresponding end of the primary phase or neutral winding. The arrangement according to the invention allows the passage of the electrodes of a welding machine for the automatic connection of the primary windings to the tongues. The dielectric strength is improved because the potential difference is transferred on either side of the toroid.

Selon une caractéristique préférentielle de l'invention, la première paire de conducteurs de raccordement de l'enroulement primaire de phase est connectée électriquement à la bilame et à la borne de phase amont. La deuxième paire de conducteurs de raccordement de l'enroulement primaire de neutre est en liaison électrique avec la borne aval de neutre, et le contact fixe de neutre. Le raccordement électrique du circuit test s'opère dans le deuxième compartiment au moyen d'une patte de traversée pour l'interconnexion de la résistance avec la corne d'arc en liaison avec le contact fixe de phase, et d'un conducteur de liaison connecté au conducteur de raccordement en liaison avec le contact fixe de neutre.According to a preferred characteristic of the invention, the first pair of connection conductors of the primary phase winding is electrically connected to the bimetallic strip and to the upstream phase terminal. The second pair of connection conductors of the primary neutral winding is in electrical connection with the downstream neutral terminal, and the fixed neutral contact. The electrical connection of the test circuit takes place in the second compartment by means of a feed-through lug for the interconnection of the resistor with the arcing horn in connection with the fixed phase contact, and a connecting conductor connected to the connecting conductor in connection with the fixed neutral contact.

Sur les figures 1 à 6, un disjoncteur différentiel 10 unipolaire et neutre est logé dans un boîtier 12 isolant, subdivisé par une paroi 14 médiane de séparation en deux parties adjacentes, comprenant un premier compartiment 16 disjoncteur et un deuxième compartiment 18 à protection différentielle du type décrit à titre d'exemple dans le brevet français 2.662.017 de la demanderesse.In FIGS. 1 to 6, a single-pole and neutral differential circuit breaker 10 is housed in an insulating housing 12, subdivided by a central wall 14 of separation into two adjacent parts, comprising a first compartment 16 circuit breaker and a second compartment 18 with differential protection of the type described by way of example in French patent 2,662,017 of the applicant.

Le premier compartiment 16 disjoncteur comporte un circuit de phase 20 et un circuit de neutre 22 séparés l'un de l'autre par une cloison 24 isolante, et reliés respectivement à une première paire de bornes 26,28 de phase, et une deuxième paire de bornes 30,32 de neutre. Les deux bornes 26,30 amont sont juxtaposées sur une même face latérale 31 étroite du boîtier 12, tandis que les deux bornes 28,32 aval sont disposées côte à côte sur l'autre face opposée 33.The first circuit breaker compartment 16 comprises a phase circuit 20 and a neutral circuit 22 separated from each other by an insulating partition 24, and connected respectively to a first pair of phase terminals 26, 28 and a second pair of neutral terminals 30.32. The two upstream terminals 26.30 are juxtaposed on the same narrow side face 31 of the housing 12, while the two downstream terminals 28.32 are arranged side by side on the other opposite face 33.

Le circuit de phase 20 (figures 1 et 3) comprend un contact mobile 34 relié électriquement à la borne 26 amont par un déclencheur à bilame 36, et un contact fixe 38 connecté à une bobine 40 d'excitation d'un déclencheur électromagnétique 42. Une première chambre d'extinction d'arc 44 est disposée entre le déclencheur électromagnétique 42 et le fond du boîtier 12, et comporte un paquet de tôles de désionisation de l'arc tiré entre les contacts 34,38.The phase circuit 20 (FIGS. 1 and 3) comprises a movable contact 34 electrically connected to the upstream terminal 26 by a bimetallic trip unit 36, and a fixed contact 38 connected to a coil 40 for exciting an electromagnetic trip device 42. A first arc extinguishing chamber 44 is arranged between the electromagnetic trip device 42 and the bottom of the housing 12, and comprises a packet of arc deionization sheets drawn between the contacts 34, 38.

Le circuit de neutre 22 (figures 1 et 2) est doté d'un contact fixe 46, d'un contact mobile 48 relié électriquement par une tresse 49 à la borne 30, et d'une deuxième chambre d'extinction d'arc 50.Le circuit de neutre 22 est situé à gauche du circuit de phase 20 et ne possède pas de déclencheur magnétothermique.The neutral circuit 22 (Figures 1 and 2) has a fixed contact 46, a movable contact 48 electrically connected by a braid 49 to terminal 30, and a second arc extinguishing chamber 50 The neutral circuit 22 is located to the left of the phase circuit 20 and does not have a thermomagnetic trip device.

Les deux contacts mobiles 34,48 sont actionnés par un premier mécanisme 52 à commande manuelle par une manette 53 et automatique par le déclencheur thermique à bilame 36 et le déclencheur électromagnétique 42 à bobine 40. Le premier mécanisme 52 peut être du type décrit dans le document FR-A-2.616.583.The two movable contacts 34, 48 are actuated by a first mechanism 52 with manual control by a lever 53 and automatic by the thermal bimetal trigger 36 and the electromagnetic trigger 42 with coil 40. The first mechanism 52 can be of the type described in the document FR-A-2.616.583.

Le deuxième compartiment 18 (figures 1, 4 et 5) est situé à droite du premier compartiment 16, et renferme un transformateur différentiel 54 ayant un enroulement secondaire 59 connecté à un relais 56 de déclenchement coopérant avec un deuxième mécanisme 58 à manette 60 de réarmement. Le deuxième mécanisme 58 est couplé avec le premier mécanisme 52 au moyen de liaisons mécaniques (non représentées) autorisant une action de déclenchement du disjoncteur 10 lors de l'émission d'un ordre de déclenchement différentiel par le relais 56, et une action poursuivie de réarmement du deuxième mécanisme 58. Le deuxième mécanisme 58 peut être du type décrit dans le document FR-A-2.628.262.The second compartment 18 (Figures 1, 4 and 5) is located to the right of the first compartment 16, and contains a differential transformer 54 having a secondary winding 59 connected to a trigger relay 56 cooperating with a second mechanism 58 with handle 60 for resetting .

Le transformateur différentiel 54 comprend un tore 62 magnétique portant un enroulement primaire de phase 64, un enroulement primaire de neutre 66, et l'enroulement secondaire de mesure 59. Un défaut à la terre provoque un déséquilibre entre les courants primaires parcourant les enroulements primaires 64,66, et engendre une tension induite aux bornes de l'enroulement secondaire 59 pour exciter le relais 56 de déclenchement.The differential transformer 54 includes a magnetic toroid 62 carrying a primary phase winding 64, a primary neutral winding 66, and the secondary measurement winding 59. A ground fault causes an imbalance between the primary currents flowing through the primary windings 64 , 66, and generates an induced voltage across the secondary winding 59 to energize the trigger relay 56.

La disposition des deux enroulements primaires 64,66 de phase et de neutre dans le deuxième compartiment 18 à protection différentielle, impose que leurs deux paires de conducteurs de raccordement 68,70; 72,74 respectifs (figure 5) traversent latéralement la paroi médiane 14 par quatre orifices 76,78; 80,82 de passage correspondants (figure 4).The arrangement of the two primary windings 64,66 of phase and neutral in the second compartment 18 with differential protection, requires that their two pairs of connection conductors 68,70; 72.74 respective (Figure 5) laterally cross the middle wall 14 through four holes 76,78; 80.82 of corresponding passages (Figure 4).

L'enroulement primaire de neutre 66 est inséré en série dans le circuit de neutre 22 par interruption de la liaison entre le contact fixe 46 de neutre, et la borne aval 32 de neutre (figure 1 et 2). Les deux orifices 80,82 des conducteurs de raccordement 72,74 se trouvent séparés l'un de l'autre par un intervalle prédéterminé, en étant situés d'un même côté, notamment à gauche, du transformateur différentiel 54.The primary neutral winding 66 is inserted in series in the neutral circuit 22 by interruption of the connection between the fixed neutral contact 46, and the downstream terminal 32 of neutral (Figure 1 and 2). The two orifices 80, 82 of the connection conductors 72, 74 are separated from each other by a predetermined interval, being located on the same side, in particular on the left, of the differential transformer 54.

Selon l'invention, les deux orifices 76,78 décalés de l'autre paire de conducteurs de raccordement 68,70 associée à l'enroulement primaire de phase 64, sont disposés à droite du transformateur différentiel 54. L'enroulement primaire de phase 64 est inséré à l'amont du circuit de phase 20, c'est à dire dans la portion située entre les contacts de phase 34,38 et la borne amont de phase 26. L'enroulement primaire de neutre 66 est inséré à l'aval du circuit de neutre 22, c'est à dire dans la portion située entre les contacts de neutre 46,48 et la borne aval de neutre 32.According to the invention, the two openings 76,78 offset from the other pair of connection conductors 68,70 associated with the primary phase winding 64, are arranged to the right of the differential transformer 54. The primary phase winding 64 is inserted upstream of the phase circuit 20, that is to say in the portion located between the phase contacts 34, 38 and the upstream phase terminal 26. The primary neutral winding 66 is inserted downstream of the neutral circuit 22, that is to say in the portion located between the neutral contacts 46, 48 and the downstream neutral terminal 32.

Le conducteur de raccordement 70 traversant l'orifice 78 inférieur est connecté au pied de la bilame 36, et l'autre conducteur de raccordement 68 traversant l'orifice 76 supérieur est branché à la plage de contact de la borne amont 26 de phase.The connection conductor 70 passing through the lower orifice 78 is connected to the base of the bimetallic strip 36, and the other connection conductor 68 passing through the upper orifice 76 is connected to the contact pad of the upstream terminal 26 of the phase.

Les quatre conducteurs de raccordement 68,70; 72,74 comportent des languettes saillantes en matériau conducteur, disposées en porte-à-faux et s'étendant parallèlement l'une à l'autre selon une direction perpendiculaire à la paroi 14 médiane. Chaque languette (figure 5 et 6) est équipée d'un évidement 84 de positionnement dans lequel est insérée l'extrémité correspondante de l'enroulement primaire de phase ou de neutre 64,66.The four connecting conductors 68.70; 72,74 have projecting tongues of conductive material, arranged in overhang and extending parallel to one another in a direction perpendicular to the wall 14 median. Each tab (FIGS. 5 and 6) is equipped with a positioning recess 84 into which the corresponding end of the primary phase or neutral winding 64,66 is inserted.

On remarque que les deux zones d'interruption des circuits de phase 20 et de neutre 22 pour l'insertion électrique des enroulements primaires 64,66 s'effectuent en des endroits différents, disposés de part et d'autre du transformateur différentiel 54, et notamment au voisinage des faces 31,33 opposées du boîtier 12. Un tel agencement facilite l'automatisation des opérations de soudage électrique des extrémités des enroulements primaires 64,66 dans les évidements 84 des languettes et améliore d'autre part la tenue diélectrique du disjoncteur 10.It is noted that the two zones of interruption of the phase 20 and neutral 22 circuits for the electrical insertion of the primary windings 64, 66 take place in different places, arranged on either side of the differential transformer 54, and especially in the vicinity of opposite faces 31.33 of the housing 12. Such an arrangement facilitates the automation of the electrical welding operations of the ends of the primary windings 64, 66 in the recesses 84 of the tongues and, on the other hand, improves the dielectric strength of the circuit breaker 10.

Le deuxième mécanisme 58 est équipé d'un dispositif de test 86 (figure 6) logé dans le deuxième compartiment 18, et ayant un bouton poussoir 88 destiné à être actionné par coulissement entre une position relevée de repos et une position enfoncée de travail. Une résistance 90 est insérée dans un circuit test 92 branché entre une patte 94 d'interconnexion du circuit de phase 20, et le conducteur de raccordement 72 de l'enroulement primaire de neutre 66. La résistance 90 est connectée en série avec un premier interrupteur 96 de protection actionné par le mécanisme 58, et un deuxième interrupteur 98 d'essai commandé par le bouton poussoir 88. L'interrupteur 96 de protection est formé par une lame 100 élastique conductrice prenant appui en position de fermeture sur un fil d'extrémité de la résistance 90 lorsque le mécanisme 58 se trouve dans l'état armé. L'interrupteur d'essai 98 comprend un brin 102 d'un ressort conducteur destiné à coopérer en position enfoncée du bouton poussoir 88, avec un conducteur de liaison 104 relié électriquement au conducteur de raccordement 72.The second mechanism 58 is equipped with a test device 86 (FIG. 6) housed in the second compartment 18, and having a push button 88 intended to be actuated by sliding between a raised position of rest and a depressed working position. A resistor 90 is inserted into a test circuit 92 connected between a lug 94 for interconnecting the phase circuit 20, and the connection conductor 72 of the primary neutral winding 66. The resistor 90 is connected in series with a first switch 96 protection activated by the mechanism 58, and a second test switch 98 controlled by the push button 88. The protection switch 96 is formed by an elastic conductive blade 100 bearing in the closed position on an end wire resistance 90 when the mechanism 58 is in the armed state. The test switch 98 comprises a strand 102 of a conducting spring intended to cooperate in the depressed position of the push button 88, with a connecting conductor 104 electrically connected to the connecting conductor 72.

La mise en circuit de la résistance 90 intervient lorsque les deux interrupteurs 96,98 sont fermés, c'est à dire dans l'état armé du mécanisme 58, et en position enfoncée de travail du bouton poussoir 88. Il en résulte un courant d'essai dans la résistance 90, lequel est détecté par le transformateur différentiel 54 qui provoque le déclenchement du deuxième mécanisme 58. Le pivotement de la platine 106 rotative du mécanisme 58 provoque l'ouverture automatique du premier interrupteur 96 de protection, entraînant l'interruption du courant d'essai dans la résistance 90,même si le bouton poussoir 88 reste maintenu en position enfoncée.The resistor 90 is switched on when the two switches 96.98 are closed, that is to say in the armed state of the mechanism 58, and in the depressed working position of the push button 88. This results in a current d test in the resistor 90, which is detected by the differential transformer 54 which triggers the second mechanism 58. The pivoting of the rotary plate 106 of the mechanism 58 causes the first protective switch 96 to open automatically, causing the interruption of the test current in the resistor 90, even if the push button 88 remains held in the depressed position.

On remarque que le raccordement électrique du circuit test 92 s'opère dans le deuxième compartiment 18, et que la prise d'information du test s'effectue en aval des contacts de neutre et de phase. La patte 94 d'interconnexion de la résistance 90 avec le circuit de phase 20 traverse la paroi médiane 14, et se trouve au potentiel de la corne d'arc supérieure 108 en liaison avec le contact fixe de phase 38. L'autre extrémité du circuit test 92 est formée par le conducteur de liaison 104 connecté au conducteur de raccordement 72 en liaison avec le contact fixe de neutre 46. Un tel raccordement du circuit test 92 en aval des contacts de phase et de neutre sert à garantir le fonctionnement fiable du disjoncteur différentiel 10 lors d'un test, en évitant notamment le transfert du potentiel de phase amont vers l'aval du circuit de neutre, ou le transfert du potentiel de neutre amont vers l'aval du circuit de phase lors de l'actionnement du bouton poussoir vers la position enfoncée.It is noted that the electrical connection of the test circuit 92 takes place in the second compartment 18, and that the taking of information from the test takes place downstream of the neutral and phase contacts. The tab 94 for interconnecting the resistor 90 with the phase circuit 20 crosses the middle wall 14, and is at the potential of the upper arcing horn 108 in connection with the fixed phase contact 38. The other end of the test circuit 92 is formed by the connection conductor 104 connected to the connection conductor 72 in connection with the fixed neutral contact 46. Such a connection of the test circuit 92 downstream of the phase and neutral contacts serves to guarantee the reliable operation of the differential circuit breaker 10 during a test, in particular avoiding the transfer of the upstream phase potential downstream of the neutral circuit, or the transfer of the upstream neutral potential downstream of the phase circuit during actuation of the push button to the depressed position.

Il est bien entendu possible d'inverser la connexion électrique amont et aval des enroulements primaires 64,66. L'enroulement primaire de phase 64 est alors connecté à l'aval des contacts de phase 34,38, et l'enroulement primaire de neutre 66 est branché à l'amont des contacts de neutre 46,48.It is of course possible to reverse the upstream and downstream electrical connection of the primary windings 64,66. The primary phase winding 64 is then connected downstream of the phase contacts 34,38, and the primary neutral winding 66 is connected upstream of the neutral contacts 46,48.

Selon une autre variante, les deux extrémités du circuit test 92 au lieu d'être branchées à l'aval (figure 6), peuvent être connectées simultanément à l'amont des contacts de phase 34,38 et de neutre 46,48.According to another variant, the two ends of the test circuit 92 instead of being connected downstream (FIG. 6), can be connected simultaneously upstream with the phase contacts 34,38 and neutral contacts 46,48.
