Les disjoncteurs à boitier moulé du genre mentionné peuvent être personnalisés en leur adjoignant pour certaines applications des éléments auxiliaires de commande de protection et/ou de signalisation. Ces auxiliaires coopèrent électriquement et/ou mécaniquement avec des éléments constitutifs du disjoncteur et il a déjà été proposé de les loger dans le boîtier moulé, mais leur montage est délicat et est obligatoirement effectué en usine, ce qui complique les problèmes de stock et de coût de fabrication.Molded case circuit breakers of the type mentioned can be personalized by adding auxiliary protection and / or signaling control elements for certain applications.

Les auxiliaires 50, 54 sont logés dans les volumes 64 et 66, délimités de part et d'autre du mécanisme 22 central longitudinalement par les parois 24, 26 et les platines 58, 60, latéralement par la paroi transversale 30 et le barreau 56 isolant en-dessous par la cloison médiane 44 et en-dessus par le couvercle 16. Chacun des blocs auxiliaires est équipé d'un bornier intégré adapté à un câblage rapide, et est facilement accessible de la face avant en position démontée du couvercle 16.The upper compartment 46 serves as a housing for the control mechanism 22 which occupies the space above the central pole S, and for various auxiliary blocks arranged laterally on either side of the mechanism 22, above the R and T poles The auxiliaries can be an undervoltage relay or trip device 50 cooperating with an auxiliary trip lever 52, an auxiliary contact device 54 controlled by a finger 53 integral with the mechanism 22 or any other device, such as a coil remote control remote release, signaling or differential protection (fig. 3). The control mechanism 22 is interposed between two fixed metal plates 58, 60 spaced apart by a transverse interval "e" and electrically isolated from the breaking chambers of the lower compartment by the middle partition 44. The mechanism 22 controls a bar 56 made of insulating material common to the three poles and rotatably mounted on an axis 62 extending transversely in the upper compartment 46 crossing the plates 55, 60 perpendicularly. The auxiliaries 50, 54 are housed in the volumes 64 and 66, delimited on either side of the central mechanism 22 longitudinally by the walls 24, 26 and the plates 58, 60, laterally by the transverse wall 30 and the bar 56 insulating below by the middle partition 44 and in above by the cover 16. Each of the auxiliary blocks is equipped with an integrated terminal block suitable for rapid wiring, and is easily accessible from the front face in the disassembled position of the cover 16.

Le compartiment inférieur 48 renferme les éléments de coupure et les dispositifs déclencheurs à éléments thermique et électromagnétique, associés aux trois pôles R, S, T. Deux parois de séparation 68, 70, en matériau isolant, s'étendent parallèlement à la direction de débattement de la manette 22 et perpendiculairement à la cloison médiane 44 du carter 14, de manière à subdiviser le compartiment inférieur 48 en trois logements 72R, 72S, 721 égaux. Trois ouvertures 74 de communication des compartiments inférieur 48 et supérieur 46 sont ménagées dans la cloison 44 médiane au voisinage de la paroi transversale 26 pour le passage des trois bras de contact 76 écheloanés régulièrement sur le barreau 56. Une fenêtre 78 additionnelle est percée dans la cloison 44 à l'opposé de l'ouverture 74 du pôle central S et au voisinage de la paroi transversale 30 pour le passage d'un organe de verrouillage 60 piloté par une barre de déclenchement 67 et coopérant avec un verrou 82 du crochet de déclenchement 64 solidaire du mécanisme 22. La barre de déclenchement 67 en matériau isolant est montée à rotation limitée sur un axe 86 transversal parallèle au barreau 56 et est agencée dan: le compartiment inférieur 48 sous la fenêtre 78. Les troi: pôles R, S, T, présentent des structures identiques dispo sées dans les logements 72R, 72S, 72T, et les mêmes repères seront utilisés par la suite pour désigner des pièces identiques. Chaque pôle comporte un contact fixe 8: coopérant en position de fermeture du disjoncteur avec un contact mobile 90 porté par le bras de contact 76 associé dont l'extrémité opposée est solidaire du barreau 56. Le bras de contact 76 est connecté électriquement à la plage 40 correspondante par une tresse 92 de liaison, et le con tact fixe 68 est relié au bilame 94 du déclencheur par un conducteur 96 recourbé d'amenée de courant, assujetti à la cloison médiane 44 par une vis de fixation 98. Un conducteur souple 99 assure la liaison électrique du bilame à la plage 42. Une chambre d'extinction d'arc 100 associé à la paire de contacts 88, 90 de chaque pôle est pourvue d'un empilage de tôles 102 de désionisation métalliques,- perpendiculaires à la plaque de base 12, et dotées d'encoches en V dirigées en direction de l'ouverture 74 correspondante de la cloison 44.The lower compartment 48 contains the cut-off elements and the triggering devices with thermal and electromagnetic elements, associated with the three poles R, S, T. Two partition walls 68, 70, made of insulating material, extend parallel to the direction of movement of the handle 22 and perpendicularly to the central partition 44 of the casing 14, so as to subdivide the lower compartment 48 in three equal 72R, 72S, 721 housings. Three openings 74 for communication of the lower 48 and upper 46 compartments are formed in the middle partition 44 in the vicinity of the transverse wall 26 for the passage of the three contact arms 76 regularly spanned on the bar 56. An additional window 78 is drilled in the partition 44 opposite the opening 74 of the central pole S and in the vicinity of the transverse wall 30 for the passage of a locking member 60 controlled by a trigger bar 67 and cooperating with a latch 82 of the trigger hook 64 secured to the mechanism 22. The trigger bar 67 of insulating material is mounted with limited rotation on a transverse axis 86 parallel to the bar 56 and is arranged in: the lower compartment 48 under the window 78. The three: poles R, S, T, have identical structures available in the housings 72R, 72S, 72T, and the same references will be used subsequently to designate identical parts. Each pole has a fixed contact 8: cooperating in the closed position of the circuit breaker with a movable contact 90 carried by the associated contact arm 76 whose opposite end is integral with the bar 56. The contact arm 76 is electrically connected to the track 40 corresponding by a braid 92 of connection, and the fixed contact 68 is connected to the bimetallic strip 94 of the trip device by a conductor 96 curved with current supply, subject to the central partition 44 by a fixing screw 98. A flexible conductor 99 ensures the electrical connection of the bimetal strip to the pad 42. An arc extinguishing chamber 100 associated with the pair of contacts 88, 90 of each pole is provided with a stack of metal deionization plates 102, - perpendicular to the plate base 12, and provided with V-shaped notches directed towards the corresponding opening 74 of the partition 44.

Un circuit dérivé de shuntage du bilame de chaque pôle R, S, T, dont le schéma de principe est décrit dans le brevet français N° 2.360.977 de la demanderesse, comporte une corne de commutation 104 perpendiculaire à la plaque de base 12 et ayant un bossage 106 à proximité du contact fixe 88 pour capter dès le début de la course d'ouverture des contacts les racines d'arc ayant pris naissance sur le contact fixe 88. La corne de commutation 104 parallèle aux tôles 102, se prolonge dans la chambre d'extinction 100 pour constituer une plaque d'extrémité. La corne 104 métallique est séparée du conducteur 96 d'amenée de courant au contact fixe 88 par une cale J06 en matériau isolant, et est en liaison électrique avec la plage 42 par un fil de commutation 110 susceptible de shunter le bilame 94 durant l'intervalle de temps entre le déclenchement et l'ouverture définitive du disjoncteur. La corne 104 est équipée d'autre part de deux joues 112, 114 parallèles de guidage de l'arc, espacées l'une de l'autre par un interstice 116 transversal de logement du contact fixe 88. Les joues 112, 114 métalliques font partie intégrante de la corne 104 par pliage en équerre de deux ailes d'extrémités et sont coiffées chacune par un capuchon (non représenté) en matériau isolant, notamment à base de polyamide, accélérant l'expansion de l'arc vers les tôles 102 de désionisation.A circuit derived from the bimetallic shunt of each pole R, S, T, whose block diagram is Crit in French Patent No. 2,360,977 of the Applicant, includes a switching horn 104 perpendicular to the base plate 12 and having a boss 106 near the fixed contact 88 to pick up from the start of the opening stroke of the contacts the arcing roots having arisen on the fixed contact 88. The switching horn 104 parallel to the sheets 102, extends into the extinguishing chamber 100 to form an end plate. The metal horn 104 is separated from the conductor 96 for supplying current to the fixed contact 88 by a shim J06 made of insulating material, and is in electrical connection with the pad 42 by a switching wire 110 capable of shunting the bimetallic strip 94 during the time interval between tripping and final opening of the circuit breaker. The horn 104 is also equipped with two parallel cheeks 112, 114 for guiding the arc, spaced from one another by a transverse gap 116 for housing the fixed contact 88. The metal cheeks 112, 114 are integral part of the horn 104 by bending at an angle of two end wings and are each capped by a cap (not shown) of insulating material, in particular based on polyamide, accelerating the expansion of the arc towards the sheets 102 of deionization.

Chaque logement 72R, 72S, 72T du compartiment inférieur 48 contient à côté de la chambre d'extinction 100 les déclencheurs thermique et électromagnétique du pôle. Le déclencheur thermique est constitué par le bilame 94 s'étendant longitudinalement entre la corne 104 et la paroi transversale 30 dans la zone médiane du logement 72R, î2S, 72T associé. La barre de déclenchement 67 commune agencée transversalement entre les trois bilames 94 et la plaque de base 12, porte trois pattes en saillie 118, une dans chaque logement 72R, 72S, 72T, sous l'extrémité libre du bilame 94 correspondant. Lors de l'apparition d'un courant de surcharge dans l'un des pôles, le bilame 94 correspondant s'infléchit vers le bas pour engager la patte 118 correspondante et faire pivoter dans le sens des aiguilles d'une montre (fig. 1) la barre de déclenchement 67 vers la position déclenchée, de déverrouillage du crochet de déclenchement 84 et d'ouverture automatique du mécanisme 22. Le déclencheur électromagnétique de chaque pôle R, S, T, comprend un circuit magnétique 120 en forme d'étrier en U renversé solidarisé à la cloison 44 par une vis 122, et craversé longitudinalement par le bilame 94 jouant le rôle de conducteur d'excitation. Une palette 124 mobile montée à pivotement sur un support 126 fixe amagnétique coopère en position attirée avec le circuit magnétique 120 pour venir en contact avec un ergot 128 d'actionnement de la barre de déclenchement 67 qui pivote vers la position déclenchée après détection d'un courant de court-circuit. Un écran isolant 130 est intercalé entre la corne de commutation 104 et le support 126 du déclencheur électromagnétique de chaque pôle. Un ressort de rappel 132 interposé entre le support 126 et la palette 124 mobile sollicite cette dernière en position écartée. La corne 104 métallique assure les fonctions de :

  • - commutation de l'arc dans le circuit dérivé de shuntage du bilame,
  • - joues de guidage 112, 114 de l'arc dans la chambre de formation d'arc,
  • - tôle d'extrémité de la chambre d'extinction 100,
  • - et d'organe de blindage entre la chambre d'extinction 100 et le déclencheur électromagnétique juxtaposé.
Each housing 72R, 72S, 72T of the lower compartment 48 contains, next to the extinguishing chamber 100, the thermal and electromagnetic triggers of the pole. The thermal trip device consists of the bimetallic strip 94 extending longitudinally between the horn 104 and the transverse wall 30 in the median zone of the associated housing 72R, 12S, 72T. The common trigger bar 67 arranged transversely between the three bimetallic strips 94 and the base plate 12, carries three projecting tabs 118, one in each housing 72R, 72S, 72T, under the free end of the corresponding bimetallic strip 94. When an overload current appears in one of the poles, the bimetallic strip 94 cor respondent bends downwards to engage the corresponding tab 118 and pivot clockwise (fig. 1) the trigger bar 67 to the triggered position, unlocking the trigger hook 84 and automatic opening of the mechanism 22. The electromagnetic trip device of each pole R, S, T, comprises a magnetic circuit 120 in the form of an inverted U-shaped stirrup secured to the partition 44 by a screw 122, and longitudinally cracked by the bimetallic strip 94 playing the role of excitation conductor. A movable pallet 124 pivotally mounted on a non-magnetic fixed support 126 cooperates in the attracted position with the magnetic circuit 120 to come into contact with a lug 128 for actuating the trigger bar 67 which pivots towards the triggered position after detection of a short circuit current. An insulating screen 130 is interposed between the switching horn 104 and the support 126 of the electromagnetic trip device of each pole. A return spring 132 interposed between the support 126 and the movable pallet 124 urges the latter in the separated position. The metallic 104 horn performs the functions of:
  • - switching of the arc in the derived bimetallic shunt circuit,
  • - guide cheeks 112, 114 of the arc in the arc-forming chamber,
  • - end sheet of the extinguishing chamber 100,
  • - And shielding member between the extinguishing chamber 100 and the juxtaposed electromagnetic trip device.

Le mécanisme de commande 22 (fig. 5 à 9), logé dans le compartiment supérieur 46, coopère avec le pôle central S, le mouvement étant transmis aux pôles R, T, adjacents par le barreau 56 transversal agencé au-dessus des ouvertures 74 de la cloison 44. Il comprend une genouillère à axe 136 sur lequel sont articulées deux biellettes 138, 140, dont l'une 138 a son extrémité opposée assujettie au barreau 56 par un axe de liaison 142 et dont l'autre 140 est articulée sur le crochet de déclenchement 84 en un point 144. Un ressort de traction 146 est ancré à l'axe 136 de la genouillère, et par son extrémité opposée au support 148 de la manette 20, le support 148 étant articulé sur un pivot fixe 150 formant le point de rotation de la manette 20.The control mechanism 22 (fig. 5 to 9), housed in the upper compartment 46, cooperates with the central pole S, the movement being transmitted to the poles R, T, adjacent by the transverse bar 56 arranged above the openings 74 of the partition 44. It comprises a toggle pin 136 on which are articulated two links 138, 140, one of which 138 has its opposite end secured to the bar reau 56 by a connecting pin 142 and the other 140 of which is articulated on the trigger hook 84 at a point 144. A tension spring 146 is anchored to the axis 136 of the toggle joint, and by its end opposite to the support 148 of the lever 20, the support 148 being articulated on a fixed pivot 150 forming the point of rotation of the lever 20.

Le crochet de déclenchement 84 en forme de U est monté à pivotement sur un axe fixe 152 et comporte un bec d'accrochage 154 coopérant en position armée avec le verrou 82 piloté par l'organe de verrouillage 80. Le verrou 82 est monté à rotation sur un axe 156, et un ressort de rappel 158 enfilé sur l'axe 156 sollicite l'organe de verrouillage 80 en position verrouillée. Le pivotement de la barre de déclenchement 67 dans le sens des aiguilles d'une montre dû à l'action du bilame 94 ou de la palette magnétique 124 de l'un des pôles R, S, T, traversé par le courant de défaut, provoque le basculement de l'organe de verrouillage 80 dans le sens de la flèche f, jusqu'à une position déverrouillée du verrou 82, et la libération du bec d'accrochage 154 du crochet de déclenchement 84. Ce dernier pivote autour de l'axe 152 sous l'action du ressort 146 en déplaçant le point d'articulation 144 de la biellette 140 vers le haut entrainant le pivotement dans le sens de la flèche f2 des bras de contact 76 et du barreau 56. La manette 20 se trouve alors dans la position stable D de déclenchement située à mi-course entre les positions F et 0. Un tel fonctionnement est classique et il suffit de rappeler que le réarmement s'effectue par un déplacement de la manette 20 dans le sens des aiguilles d'une montre depuis la position D jusqu'à une position R de réarmement (voir fig.l) voisine de la position 0, assurant l'accrochage du crochet de déclenchement 84 au verrou 82. La fermeture du disjoncteur intervient ensuite par une rotation inverse de la manette 20 actionnée manuellement vers la position F.The U-shaped trigger hook 84 is pivotally mounted on a fixed axis 152 and comprises a hooking spout 154 cooperating in the armed position with the latch 82 piloted by the locking member 80. The latch 82 is rotatably mounted on an axis 156, and a return spring 158 threaded on the axis 156 biases the locking member 80 in the locked position. The pivoting of the trigger bar 67 in the clockwise direction due to the action of the bimetal strip 94 or the magnetic pallet 124 of one of the poles R, S, T, crossed by the fault current, causes the locking member 80 to tilt in the direction of the arrow f, to an unlocked position of the lock 82, and the release of the hooking spout 154 from the trigger hook 84. The latter pivots around the axis 152 under the action of spring 146 by moving the articulation point 144 of the link 140 upwards causing the pivoting in the direction of arrow f 2 of the contact arms 76 and of the bar 56. The lever 20 is located then in the stable triggering position D located halfway between positions F and 0. Such an operation is conventional and it suffices to recall that the reset is effected by a movement of the lever 20 in the direction of the needles. a watch from position D to a reset position R (see fig.l) close to position 0, ensuring the hooking of the release hook 84 to the latch 82. The closing of the circuit breaker then takes place by reverse rotation of the handle 20 actuated manually towards position F.

Le mécanisme de commande 22 est équipé d'autre part d'un dispositif de blocage 160 susceptible de stopper le déplacement de la manette 20 dans le sens ouverture en une position intermédiaire S lors du soudage des contacts 90, 88. Le dispositif de blocage 160 (voir fig. 6 à 9) comporte une lumière 162 ménagée dans le support 148 de la manette 20 et ayant une dent 164 faisant saillie du bord interne de la lumière 162. L'axe de liaison 142 de la biellette 138 est engagé dans la lumière 162 et l'ensemble est agencé pour autoriser un mouvement relatif axe 142, lumière 162, libre lors d'une commande manuelle par la manette 20 ou lors d'un déclenchement automatique du disjoncteur entrainant l'ouverture normale des contacts 90, 88 (fig. 8). En cas de soudure de ces derniers, l'axe de liaison 142 reste immobile et la dent 164 vient buter contre l'axe 142 en empêchant le déplacement de la manette 20 vers la position 0. La manette 20 est alors bloquée dans la position S (fig. 9) et revient automatiquement en position F en cas de relâchement.The control mechanism 22 is further equipped with a blocking device 160 capable of stopping the movement of the lever 20 in the opening direction in an intermediate position S when the contacts 90, 88 are welded. The blocking device 160 (see fig. 6 to 9) comprises a light 162 formed in the support 148 of the lever 20 and having a tooth 164 projecting from the internal edge of the light 162. The connecting axis 142 of the link 138 is engaged in the light 162 and the assembly is arranged to allow relative movement axis 142, light 162, free during manual control by lever 20 or during automatic tripping of the circuit breaker causing the normal opening of contacts 90, 88 (fig. 8). In case of welding of the latter, the connecting axis 142 remains stationary and the tooth 164 abuts against the axis 142 preventing the movement of the handle 20 to the position 0. The handle 20 is then locked in the position S (fig. 9) and automatically returns to position F in the event of release.

Trois écrans isolants de protection 168 amovibles obturent la paroi transversale 28 du compartiment supérieur 46 après montage des organes du disjoncteur, et sont maintenus en place par emboîtement du couvercle 16 Chaque écran 168 recouvre le bras de contact 76 du pôle correspondant, et sa tresse 92 de liaison à la plage 40 en assurant un bon isolement et la sécurité des personnes.Three removable protective screens 168 protect the transverse wall 28 of the upper compartment 46 after mounting of the circuit breaker members, and are held in place by fitting the cover 16 Each screen 168 covers the contact arm 76 of the corresponding pole, and its braid 92 connecting to beach 40 ensuring good isolation and personal safety.
