Description

Domaine de l'inventionField of the invention

L'invention concerne un déclencheur électronique pour appareil électrique multipolaire de protection de ligne, du type disjoncteur. L'invention concerne plus particulièrement les appareils tétrapolaires, comportant un neutre à droite ou à gauche en sus des trois phases.The invention relates to an electronic trip device for a multipolar electric line protection device, of the circuit breaker type. The invention relates more particularly to four-pole devices, having a neutral on the right or on the left in addition to the three phases.

Tout comme un déclencheur magnétothermique, un déclencheur électronique détecte les courants de surcharge et les courants de court-circuit pour provoquer l'ouverture des contacts du disjoncteur.Like a thermomagnetic trip unit, an electronic trip unit detects overload currents and short-circuit currents to open the circuit breaker contacts.

L'intérêt d'un déclencheur électronique est de pouvoir disposer d'une large plage de réglages, notamment du niveau de déclenchement et du délai de déclenchement. Il consiste généralement en un actionneur commandé par une carte électronique qui surveille le courant qui passe dans le disjoncteur par l'intermédiaire de capteurs.The advantage of an electronic release is to be able to have a wide range of settings, including the trigger level and the trigger time. It usually consists of an actuator controlled by an electronic card that monitors the current that passes through the circuit breaker via sensors.

Le déclencheur électronique est associé à un bloc de coupure contenant notamment la chambre de coupure, les contacts fixes et mobiles, et la serrure, afin de former le disjoncteur.The electronic release is associated with a cutoff block containing in particular the interrupting chamber, the fixed and moving contacts, and the lock, in order to form the circuit breaker.

Un déclencheur électronique comprend classiquement au moins un bloc de mesure de courant ayant des capteurs de courant et un bloc de traitement électrique de la mesure de courant ayant une carte électronique et un actionneur.An electronic trigger conventionally comprises at least one current measurement block having current sensors and a current measurement electrical processing block having an electronic card and an actuator.

Une liaison électrique et une liaison mécanique sont réalisées entre ces deux blocs au sein du déclencheur.An electrical connection and a mechanical connection are made between these two blocks within the trigger.

Etat de la techniqueState of the art

Un appareil, du type disjoncteur, est donc principalement constitué d'un bloc de coupure et d'un déclencheur. Le tout est intégré dans une base.An apparatus, of the circuit breaker type, is therefore mainly composed of a breaking block and a trigger. Everything is integrated into a base.

Il existe principalement trois formats de base :

  • la base tripolaire
  • la base tétrapolaire avec le neutre situé à gauche
  • la base tétrapolaire avec le neutre situé à droite.
There are mainly three basic formats:
  • the tripolar base
  • the four-pole base with the neutral located on the left
  • the four-pole base with the neutral located on the right.

De la même manière, pour que le déclencheur puisse s'intégrer dans le disjoncteur, il existe trois formats de structure pour le déclencheur :

  • une structure tripolaire
  • une structure tétrapolaire avec le neutre situé à gauche
  • une structure tétrapolaire avec le neutre situé à droite.
In the same way, for the trigger to fit into the breaker, there are three structure formats for the trigger:
  • a tripolar structure
  • a four-pole structure with the neutral located on the left
  • a four-pole structure with the neutral located on the right.

A chaque format de structure de déclencheur correspond une référence particulière.Each trigger structure format corresponds to a particular reference.

La dimension de la structure du déclencheur est donc spécifique au nombre de voie de courant que comporte le disjoncteur, et est de plus spécifique à la norme en matière de positionnement du neutre selon les pays (à droite ou à gauche).The dimension of the trigger structure is therefore specific to the number of current path that the circuit breaker has, and is also specific to the standard for positioning the neutral according to the country (right or left).

Il en est de même pour la(les) carte(s) électronique(s) que comporte le déclencheur, qui est(sont) spécifique(s) au nombre de voie de courant et à la position du neutre. Cela rajoute autant de références de pièces différentes à produire.It is the same for the electronic card (s) that includes the trigger, which is (are) specific to the number of current path and the position of the neutral. This adds as many references of different pieces to produce.

Un déclencheur électronique pour appareil électrique multipolaire de protection de ligne est notamment connu du document DE 10 2006 059384 A1 .An electronic trip device for a multipolar electric line protection device is notably known from the document DE 10 2006 059384 A1 .

Résumé de l'inventionSummary of the invention

La présente invention a pour objectif de diminuer le nombre de références, et de proposer une solution universelle de structure de déclencheur, quel que soit le nombre de pôles (tripolaire ou tétrapolaire) que comporte l'appareil dans lequel il est intégré, et quel que soit la norme propre au pays dans lequel il est commercialisé.The present invention aims to reduce the number of references, and to provide a universal solution of trigger structure, regardless of the number of poles (three-pole or four-pole) that includes the device in which it is integrated, and whatever the country-specific standard in which it is marketed.

Pour y parvenir, l'invention concerne un déclencheur électronique pour appareil électrique multipolaire de protection de ligne, du type disjoncteur, comprenant un bloc de mesure de courant et un bloc de traitement électrique de la mesure de courant. Ledit bloc de mesure et ledit bloc de traitement s'étendent essentiellement le long d'une direction de référence.To achieve this, the invention relates to an electronic trip device for a multipole electric circuit protection device, of the circuit breaker type, comprising a current measurement block and an electrical treatment block of the current measurement. Said measurement block and said processing block extend essentially along a reference direction.

Ce déclencheur électronique se caractérise à titre principal en ce que lesdits blocs de mesure et de traitement consistent en des blocs tripolaires raccordés l'un à l'autre, et en ce que le déclencheur comporte des moyens d'adjonction d'un neutre à droite ou à gauche dudit bloc de mesure et/ou dudit bloc de traitement, c'est-à-dire des moyens d'adjonction d'un neutre devant ou derrière ledit bloc de mesure et/ou ledit bloc de traitement selon la direction de référence.This electronic trigger is mainly characterized in that said measurement and processing blocks consist of three-pole blocks connected to each other, and in that the trigger comprises means for adding a neutral to the right. or to the left of said measurement block and / or of said processing block, that is to say means of adding a neutral in front of or behind said measurement block and / or said processing block in the reference direction .

L'idée principale à la base de l'invention est de ne disposer que d'un seul format de structure de déclencheur, consistant en une structure tripolaire.The main idea underlying the invention is to have only one format of trigger structure, consisting of a three-pole structure.

Cette structure tripolaire peut aussi bien être utilisée pour un appareil tripolaire, que pour un appareil tétrapolaire avec neutre devant ledit bloc de mesure et/ou ledit bloc de traitement selon la direction de référence, ou encore un appareil tétrapolaire avec un neutre derrière ledit bloc de mesure et/ou ledit bloc de traitement selon la direction de référence. Pour obtenir un déclencheur tétrapolaire, il suffit donc de repartir de sa structure tripolaire, et de lui adjoindre un élément unipolaire devant ou derrière ledit bloc de mesure et/ou ledit bloc de traitement selon la direction de référence, comme cela sera développé dans la suite de la description.This three-pole structure can be used both for a three-pole apparatus, for a four-pole apparatus with a neutral in front of said measurement block and / or said processing block in the reference direction, or a four-pole apparatus with a neutral behind said block of measuring and / or said processing block according to the reference direction. To obtain a four-pole release, it is therefore sufficient to start from its tripolar structure, and to add a unipolar element in front of or behind said measurement block and / or said processing block in the reference direction, as will be developed in the following of the description.

Selon les différents modes de réalisation de l'invention, qui pourront être pris ensemble ou séparément :

  • Ledit premier moyen d'adjonction d'un neutre consistent en une rallonge de mesure unipolaire disposée devant ou derrière ledit bloc de mesure et/ou ledit bloc de traitement selon la direction de référence, et/ou ledit deuxième moyen d'adjonction d'un neutre consiste en une rallonge de traitement unipolaire disposée devant ou derrière ledit bloc de mesure et/ou ledit bloc de traitement selon la direction de référence: il existe donc une référence supplémentaire pour la rallonge de mesure, quel que soit son positionnement, et une référence supplémentaire pour la rallonge de traitement, quel que soit son positionnement. Avec trois éléments, à savoir une structure tripolaire de déclencheur, une rallonge de mesure, et une rallonge de traitement, il est possible de fabriquer un déclencheur compatible pour n'importe quel appareil tripolaire et tétrapolaire.
  • ladite rallonge de mesure est fixée au bloc de mesure et isolée électriquement du bloc de mesure au moyen d'une pièce support conçue dans un matériau isolant électriquement.
  • ladite pièce support consiste en une pièce symétrique, comprenant une paroi de séparation dotée de part et d'autre de moyens d'accroche pour se fixer d'un côté au bloc de mesure, et de l'autre côté à la rallonge mesure : cette pièce support, de par sa symétrie, peut ainsi être positionnée aussi bien devant que derrière dudit bloc de mesure et/ou dudit bloc de traitement selon la direction de référence.
  • ladite rallonge de traitement est raccordée électriquement au bloc de traitement au moyen de fiches de connexion.

Description détailléedetailed description

Le déclencheur électronique de l'invention se compose d'un bloc de mesure 1 de courant et d'un bloc de traitement 2 électronique de la mesure du courant. Un tel déclencheur électronique s'intègre dans un appareil électrique de protection de ligne, du type disjoncteur, comportant également un bloc de coupure.The electronic release of the invention consists of a current measurement block 1 and an electronic processing block 2 of the current measurement. Such an electronic release integrates into an electrical line protection device, circuit breaker type, also having a breaking block.

En référence à la figure 1, le bloc de mesure 1 de courant se compose d'un boîtier 6 renfermant des capteurs 9. Il comporte une face de raccordement 20 au bloc de traitement 2, ainsi que deux faces latérales 18,19. Les faces latérales 18, 19 peuvent être perpendiculaires à la face de raccordement 20.With reference to the figure 1 , the measuring block 1 of current consists of a housing 6 containing sensors 9. It comprises a connecting face 20 to the treatment block 2, and two side faces 18,19. The lateral faces 18, 19 may be perpendicular to the connecting face 20.

Dans le cas présenté, ce bloc de mesure 1 est adapté pour fonctionner dans un disjoncteur tripolaire puisqu'il présente trois tronçons 3,4,5 identiques, chaque tronçon étant prévu pour un pôle.In the case presented, this measurement block 1 is adapted to operate in a three-pole circuit breaker since it has three identical sections 3,4,5, each section being provided for a pole.

Chaque tronçon 3,4,5 contient un capteur 9 de mesure de courant, qui consiste en un enroulement de Rogowski, et un transformateur de courant (non visible).Each section 3,4,5 contains a current measuring sensor 9, which consists of a Rogowski winding, and a current transformer (not visible).

Le capteur 9 et le transformateur consistent en des pièces de révolution, plus précisément en des tores, disposés coaxialement.The sensor 9 and the transformer consist of parts of revolution, more precisely tori, arranged coaxially.

Ils présentent un orifice central 10 à l'intérieur duquel s'insère un conducteur provenant du bloc de coupure (non illustré), et dont on veut connaître le courant.They have a central orifice 10 within which a conductor coming from the breaking block (not shown) is inserted and whose current is to be known.

Le calibre du capteur 9 varie en fonction du calibre du disjoncteur.The size of the sensor 9 varies according to the size of the circuit breaker.

Le transformateur de courant sert à alimenter des cartes électroniques 14 contenues dans le bloc de traitement 2 qui sera décrit plus loin.The current transformer is used to feed electronic cards 14 contained in the processing block 2 which will be described later.

Le capteur 9 et le transformateur comportent des sorties filaires raccordées à un connecteur mâle 8 logé dans une zone d'accueil 7 prévue à cet effet et saillant du boitier 6. Cette zone 7 est centrée sur chaque tronçon 3,4,5 du bloc de mesure 1, dans un plan transversal passant par l'axe du capteur 9 et du transformateur. Ledit bloc de mesure 1 et ledit bloc de traitement 2 s'étendent essentiellement le long d'une direction de référence X.The sensor 9 and the transformer comprise wire outputs connected to a male connector 8 housed in a reception area 7 provided for this purpose and protruding from the housing 6. This zone 7 is centered on each section 3,4,5 of the measurement block 1, in a transverse plane passing through the axis of the sensor 9 and the transformer. Said measurement block 1 and said processing block 2 extend essentially along a reference direction X.

Ce connecteur mâle 8 s'enfiche dans un connecteur femelle 13 prévu à cet effet dans le bloc de traitement 2 électrique de la mesure de courant.This male connector 8 plugs into a female connector 13 provided for this purpose in the electrical treatment block 2 of the current measurement.

Le bloc de traitement 2 se compose d'un boîtier 15 comportant une face de raccordement 11 au bloc de mesure 1, ainsi que deux faces latérales 16,17. Les faces latérales 16,17 peuvent être perpendiculaires à la face de raccordement 11.The processing block 2 consists of a housing 15 having a connection face 11 to the measurement block 1, as well as two lateral faces 16, 17. The lateral faces 16, 17 may be perpendicular to the connection face 11.

Ce boîtier 15 renferme une pluralité de cartes électroniques 14, alimentées par les transformateurs du bloc de mesure 1, et traitant les signaux entrants en provenance des capteurs 9 du bloc de mesure 1. Le bloc de traitement 2 comporte également une serrure intermédiaire 12, apte à déclencher la serrure principale du disjoncteur (non représentée), sur ordre d'une carte électronique 14 dans le cas où elle détecte un défaut (surtension, court-circuit).This housing 15 encloses a plurality of electronic boards 14, fed by the transformers of the measurement block 1, and processing the incoming signals from the sensors 9 of the measurement block 1. The processing block 2 also comprises an intermediate lock 12, suitable to trigger the main lock of the circuit breaker (not shown), on the order of an electronic card 14 in the case where it detects a fault (overvoltage, short circuit).

Ce bloc de traitement 2 existe en deux versions. La différence entre ces deux versions étant le nombre de cartes électroniques lié aux fonctionnalités du disjoncteur. Une première version comporte des fonctions de base, et une seconde version comporte des fonctions de base plus des fonctions avancées, comme la mesure de tension pour faire du calcul de puissance et de la communication.This processing block 2 exists in two versions. The difference between these two versions is the number of electronic cards related to the functions of the circuit breaker. A first version includes basic functions, and a second version includes basic functions plus advanced functions, such as voltage measurement for power calculation and communication.

Dans le cas présenté, ce bloc de traitement 2 est adapté pour fonctionner dans un disjoncteur tripolaire puisqu'il présente trois tronçons 3,4,5 identiques, chaque tronçon étant prévu pour un pôle.In the case presented, this processing unit 2 is adapted to operate in a three-pole circuit breaker since it has three identical sections 3,4,5, each section being provided for a pole.

Chaque tronçon 3,4,5 contient un connecteur femelle 13, disposé en regard d'un connecteur mâle 8 du bloc de mesure 1. Le boîtier 15 est ajouré au niveau des connecteurs femelles 13 afin de les laisser accessible pour le raccordement avec les connecteurs mâles 8. Chaque connecteur femelle 13 est directement fixé à une carte électronique 14 qui reçoit donc l'information de la mesure du courant provenant du capteur 9 correspondant du bloc de mesure 1, et qui est alimentée via le transformateur correspondant du bloc de mesure 1.Each section 3,4,5 contains a female connector 13 disposed opposite a male connector 8 of the measurement block 1. The housing 15 is perforated at the female connectors 13 in order to leave them accessible for connection with the connectors 8. Each female connector 13 is directly attached to an electronic card 14 which therefore receives the current measurement information from the corresponding sensor 9 of the measurement block 1, and which is supplied via the corresponding transformer of the measurement block 1 .

Le raccordement électrique des deux blocs 1,2 s'effectue donc par simple enfichage des trois connecteurs mâles 8 dans les trois connecteurs femelles 23, selon une seule direction d'enfichage, correspondant à la direction d'assemblage des blocs 1,2 et perpendiculaire à la direction de référence X.The electrical connection of the two blocks 1, 2 is therefore made by simply plugging the three male connectors 8 into the three female connectors 23, in a single direction of insertion, corresponding to the assembly direction of the blocks 1.2 and perpendicular to the reference direction X.

Vis-à-vis de la figure 1, pour raccorder électriquement le bloc de mesure 1 au bloc de traitement 2, il suffit de retourner le bloc de mesure 1 selon la flèche sur la droite, puis de rapprocher les deux blocs 1,2 de manière à ce que les trois connecteurs mâles 8 et femelles 23 s'enfichent.Vis-à-vis the figure 1 to electrically connect the measuring block 1 to the process block 2, simply return the measurement block 1 according to the arrow on the right, then bring the two blocks 1.2 together so that the three male connectors 8 and females 23 flee.

Ces deux blocs 1,2 assemblés sont illustrés en figure 2, montrant le recto du déclencheur électronique tripolaire, et en figure 3, montrant le verso du déclencheur électronique tripolaire. Cette structure tripolaire du déclencheur correspond à la structure de base de l'invention. Il n'y a donc qu'une seule référence pour la structure de base.These two blocks 1,2 assembled are illustrated in figure 2 , showing the front of the tripolar electronic trigger, and figure 3 , showing the back of the tripolar electronic trigger. This tripolar structure of the trigger corresponds to the basic structure of the invention. So there is only one reference for the basic structure.

Au niveau d'une première face latérale 16, le bloc de traitement 2 comporte deux fiches 21,22 de connexion accessibles depuis l'extérieur via un jour pratiqué dans le boîtier 15.At a first lateral face 16, the treatment block 2 comprises two connection plugs 21, 22 accessible from the outside via a day made in the case 15.

Plus précisément, il comporte :

  • une fiche de connexion d'un premier type 21 permettant d'accéder à une fonction particulière du déclencheur. Il est donc possible de se raccorder sur cette fiche depuis l'extérieur. Cette fiche peut par exemple servir à une fonction alarme qui reflète l'état du disjoncteur. Lorsque le courant dépasse un certain seuil, l'état change et l'utilisateur en est informé. Cette fiche de connexion d'un premier type 21 comporte de préférence deux points de raccordement, et consiste en une fiche mâle.
  • une fiche de connexion d'un second type 22, sur laquelle il est possible de raccorder un auxiliaire. Il peut par exemple s'agir d'un neutre externe, c'est-à-dire d'un conducteur de neutre dont on souhaite mesurer le courant, mais que l'on ne souhaite pas couper, contrairement aux trois pôles du disjoncteur. Cette fiche de connexion d'un second type 22 comporte de préférence cinq points de raccordement utilisés de la manière suivante : deux points pour un transformateur de courant (pour l'alimentation des cartes électroniques), deux points pour un capteur de courant (pour la mesure du courant), et un point facultatif pour la mesure de tension. Cette fiche de connexion 22 consiste en une fiche mâle.
More precisely, it includes:
  • a connection plug of a first type 21 for accessing a particular function of the trigger. It is therefore possible to connect to this card from the outside. This plug can for example be used for an alarm function that reflects the state of the circuit breaker. When the current exceeds a certain threshold, the state changes and the user is informed. This connection plug of a first type 21 preferably comprises two connection points, and consists of a plug.
  • a connection plug of a second type 22, on which it is possible to connect an auxiliary. It may for example be an external neutral, that is to say a neutral conductor whose current we want to measure, but that we do not want to cut, unlike the three poles of the circuit breaker. This connection plug of a second type 22 preferably comprises five connection points used in the following manner: two points for a current transformer (for supplying the electronic cards), two points for a current sensor (for the current measurement), and an optional point for voltage measurement. This connection plug 22 consists of a plug.

Au niveau d'une seconde face latérale 17, le bloc de traitement 2 comporte :

  • une fiche de connexion d'un second type 42 (voir figures 12 et 13), similaire à la fiche 22, sur laquelle il est possible de raccorder un auxiliaire. Il peut par exemple s'agir d'un neutre externe, comme expliqué précédemment.
At a second side face 17, the treatment block 2 comprises:
  • a plug of a second type 42 (see Figures 12 and 13 ), similar to plug 22, on which it is possible to connect an auxiliary. It may for example be an external neutral, as explained above.

Dans le cadre de la présente invention, ces deux fiches de connexion d'un second type 22,42 sont utilisées pour adjoindre un neutre interne à droite ou à gauche du déclencheur électronique, c'est-à dire devant ou derrière le déclencheur électronique, afin d'obtenir un déclencheur tétrapolaire.In the context of the present invention, these two connection plugs of a second type 22, 42 are used to add an internal neutral to the right or left of the electronic trigger, ie in front of or behind the electronic trigger, to obtain a four-pole trigger.

Concrètement, comme illustré en figure 4, une rallonge de mesure 24 et une rallonge de traitement 25 sont rajoutées sur le côté droit du bloc de mesure 1 et/ou du bloc de traitement 2, c'est-à dire devant ledit bloc de mesure 1 et/ou ledit bloc de traitement 2 selon la direction de référence X. Ces deux rallonges 24,25 forment un nouveau tronçon 23 prévu pour le pole relatif au neutre. Ce tronçon 23 est aligné avec les autres tronçons 3,4,5, et jouxte le tronçon 5. Ce nouveau tronçon 23 comporte, comme les autres tronçons 3,4,5, un capteur 9 de mesure de courant et un transformateur de courant, ainsi qu'un connecteur femelle 13, un connecteur mâle 8, et une carte électronique. Il est donc équipé de la même manière que les autres tronçons 3,4,5.Concretely, as illustrated in figure 4 a measuring extension 24 and a processing extension 25 are added on the right side of the measurement block 1 and / or the process block 2, ie in front of said measurement block 1 and / or said block of measurement. treatment 2 in the reference direction X. These two extensions 24,25 form a new section 23 provided for the pole relative to the neutral. This section 23 is aligned with the other sections 3,4,5, and adjoins the section 5. This new section 23 comprises, like the other sections 3,4,5, a current measuring sensor 9 and a current transformer, as well as a female connector 13, a male connector 8, and an electronic card. It is therefore equipped in the same way as the other sections 3,4,5.

Le déclencheur électronique, ainsi formé des quatre tronçons 3,4,5,23, est passé d'un format tripolaire à un format tétrapolaire avec le neutre à droite, c'est-à dire devant ledit bloc de mesure 1 et ledit bloc de traitement 2 selon la direction de référence X, tout en conservant la même structure de base tripolaire à laquelle des rallonges unipolaires 24,25 ont été ajoutées.The electronic trigger, thus formed of the four sections 3,4,5,23, has changed from a three-pole format to a four-pole format with the neutral on the right, that is to say in front of said measurement block 1 and said block of treatment 2 according to the reference direction X, while maintaining the same tripolar base structure to which unipolar extensions 24,25 were added.

Comme illustré en figure 5, une rallonge de mesure 24 et une rallonge de traitement 25 sont rajoutées sur le côté gauche du bloc de mesure 1 et du bloc de traitement 2, c'est-à dire derrière ledit bloc de mesure 1 et ledit bloc de traitement 2 selon la direction de référence X. Ces deux rallonges 24,25 forment un nouveau tronçon 23 prévu pour le pole relatif au neutre. Ce tronçon 23 est aligné avec les autres tronçons 3,4,5, et jouxte le tronçon 3. Ce nouveau tronçon 23 comporte, comme les autres tronçons 3,4,5, un capteur 9 de mesure de courant et un transformateur de courant, ainsi qu'un connecteur femelle 13, un connecteur mâle 8, et une carte électronique. Il est donc équipé de la même manière que les autres tronçons 3,4,5.As illustrated in figure 5 a measuring extension 24 and a processing extension 25 are added on the left side of the measurement block 1 and the processing block 2, ie behind said measurement block 1 and said treatment block 2 according to the reference direction X. These two extensions 24,25 form a new section 23 provided for the pole relative to the neutral. This section 23 is aligned with the other sections 3,4,5, and abuts the section 3. This new section 23 comprises, like the other sections 3,4,5, a current measuring sensor 9 and a current transformer, as well as a female connector 13, a male connector 8, and an electronic card. It is therefore equipped in the same way as the other sections 3,4,5.

Le déclencheur électronique, ainsi formé des quatre tronçons 23,3,4,5, est passé d'un format tripolaire à un format tétrapolaire avec le neutre à gauche, c'est-à dire derrière ledit bloc de mesure 1 et ledit bloc de traitement 2 selon la direction de référence X, tout en conservant la même structure de base tripolaire à laquelle des rallonges unipolaires 24,25 ont été ajoutées.The electronic trip unit, thus formed of the four sections 23, 3,4,5, has changed from a three-pole format to a four-pole format with the neutral on the left, ie behind said measurement block 1 and said block of treatment 2 according to the reference direction X, while maintaining the same tripolar base structure to which unipolar extensions 24,25 were added.

Au final, avec une structure de base tripolaire et un ensemble de rallonges (mesure et traitement), il est possible de former toutes les configurations tripolaires et tétrapolaires de déclencheur. Il n'est plus nécessaire d'avoir des cartes électroniques spécifiques, et structures de déclencheur spécifiques. Le nombre de références de sous-ensemble en fabrication a donc été réduit au maximum avec cette invention.Finally, with a three-pole base structure and a set of extensions (measurement and processing), it is possible to form all three-pole and four-pole trigger configurations. It is no longer necessary to have specific electronic cards, and specific trigger structures. The number of subassembly references in manufacture has therefore been reduced to a minimum with this invention.

Que le neutre soit positionné à droite ou à gauche, c'est-à dire devant ou derrière ledit bloc de mesure 1 et ledit bloc de traitement 2 selon la direction de référence X, les informations en provenance de la rallonge de traitement 25, notamment la mesure du courant et la mesure de la tension, sont récupérées via la fiche proximale de second type 42,22 du bloc de traitement 2.Whether the neutral is positioned to the right or to the left, that is to say in front of or behind said measurement block 1 and said processing block 2 in the reference direction X, the information coming from the processing extension 25, in particular the measurement of the current and the measurement of the voltage are recovered via the second type proximal plug 42, 22 of the processing block 2.

En effet la rallonge de traitement 25 peut mesurer la tension du neutre, au moyen d'une carte électronique supplémentaire ajoutée dans la rallonge de traitement 25, et depuis laquelle s'étend une lame flexible conductrice qui touche la borne en sortie de la rallonge de mesure 24. Cette carte électronique supplémentaire est donc capable de renvoyer l'information concernant la tension du neutre, vers le bloc de traitement 2.Indeed, the processing extension 25 can measure the voltage of the neutral, by means of an additional electronic card added in the treatment extension 25, and from which extends a flexible conductive blade which touches the terminal at the output of the extension cable. This additional electronic card is therefore able to send the information concerning the neutral voltage to the processing block 2.

La rallonge de traitement 25, mieux illustrées aux figures 7 à 9, se compose d'un boîtier comportant une face de raccordement 41 à la rallonge de mesure 24, ainsi que deux faces latérales 31,32. Les faces latérales 31,32 peuvent être perpendiculaires à la face de raccordement 41.The treatment extension 25, better illustrated at Figures 7 to 9 , consists of a housing having a connecting face 41 to the measuring extension 24, and two side faces 31,32. The lateral faces 31, 32 may be perpendicular to the connecting face 41.

Sur la figure 7, montrant le recto de la rallonge de traitement 25, sont visibles le connecteur femelle 13, ainsi qu'un morceau de la carte électronique 26 associée. Chaque face latérale 30,31 comporte un jour 32,33 par lequel s'échappent des fiches de différents types.On the figure 7 , showing the front of the treatment extension 25, are visible the female connector 13, and a piece of the associated electronic card 26. Each side face 30,31 comprises a day 32,33 through which leaves of different types escape.

Plus précisément, comme cela est visible en figure 8, la première face latérale 30 comporte un jour 32 faisant apparaître une fiche de connexion d'un premier type 34, et duquel peut s'échapper une fiche de connexion d'un second type 28.More precisely, as is visible in figure 8 , the first lateral face 30 has a day 32 showing a connection plug of a first type 34, and which can escape a connection plug of a second type 28.

La seconde face latérale 31 comporte un jour 33 duquel peuvent s'échapper une fiche de connexion d'un premier type 27 et la fiche de connexion d'un second type 28.The second lateral face 31 has a day 33 from which a connection plug of a first type 27 and the connection plug of a second type 28 can escape.

Les deux cas de figure de l'échappement de la fiche 28 sont donc représentés sur cette figure 8. Toutes ces fiches 27,28,34 sont reliées à la carte électronique 26.Both cases of the exhaust of the plug 28 are therefore represented on this figure 8 . All these sheets 27,28,34 are connected to the electronic card 26.

De façon plus concrète, la fiche 27 consiste en une fiche femelle à deux points de raccordement. Elle est reliée à la carte électronique 26 via une liaison filaire 40 consistant en deux fils connectés sur des pistes de la carte électronique. Ces pistes sont reliées à la fiche 34 qui consiste en une fiche mâle à deux points de raccordement, fixée à la carte électronique et accessible depuis le jour 32 de la première face latérale 30.More specifically, the plug 27 consists of a female plug with two connection points. It is connected to the electronic card 26 via a wired link 40 consisting of two son connected to the tracks of the electronic card. These tracks are connected to the plug 34 which consists of a plug with two connection points, fixed to the electronic card and accessible since the day 32 of the first lateral face 30.

La fiche 28 consiste en une fiche femelle à cinq points de raccordement. Elle est reliée à la carte électronique 26 de mesure de courant via une liaison filaire 29a consistant en quatre fils connectés sur des pistes de cette carte 26, et à une carte électronique supplémentaire (non représentée) de mesure de tension via une liaison filaire 29b consistant en un fil connecté sur une piste de cette carte. Les fils sont suffisamment souples pour faire passer la fiche 28 à travers le jour 32 à droite ou à travers le jour 33 à gauche, c'est-à dire pour faire passer la fiche 28 à travers le jour 32 devant ou derrière ledit bloc de mesure 1 et ledit bloc de traitement 2 selon la direction de référence X, en fonction de la position de la rallonge de traitement 25 par rapport au bloc de traitement 2.The plug 28 consists of a female plug with five connection points. It is connected to the current measurement electronic board 26 via a wired link 29a consisting of four wires connected on tracks of this card 26, and to an additional electronic circuit board (not shown) for measuring voltage via a wire link 29b consisting of in a wire connected on a track of this map. The threads are sufficiently flexible to pass the plug 28 through the day 32 to the right or through the day 33 to the left, that is to say to pass the plug 28 through the day 32 in front of or behind said block of measurement 1 and said processing block 2 in the reference direction X, depending on the position of the treatment extension 25 with respect to the processing block 2.

La longueur des fils des liaisons filaires 40 et 29 n'est pas forcément représentative de la réalité sur cette figure 8.The length of the wires of the wired links 40 and 29 is not necessarily representative of the reality on this figure 8 .

Il est aussi à noter que les fiches mâle et femelle pourraient très bien être inversées.It should also be noted that the male and female plugs could very well be reversed.

La figure 12 reprend le cas de la figure 4, avec le neutre à droite, c'est-à dire devant ledit bloc de mesure 1 et ledit bloc de traitement 2 selon la direction de référence X, les pièces étant séparées afin d'illustrer les liaisons filaires 40,29.The figure 12 takes up the case of the figure 4 , with the neutral on the right, that is to say in front of said measurement block 1 and said processing block 2 in the reference direction X, the parts being separated in order to illustrate the wire links 40,29.

Dans ce cas, la première face latérale 16 du bloc de traitement 2, se retrouve en vis-à-vis de la seconde face latérale 31 de la rallonge de traitement 25.In this case, the first lateral face 16 of the treatment block 2 is found opposite the second lateral face 31 of the treatment extension 25.

Afin qu'il soit toujours possible d'accéder à une fonction particulière du déclencheur via l'extérieur, la fiche de connexion de premier type 21 présente sur la face latérale 16 du bloc de traitement 2 est déportée sur la face latérale 30 de la rallonge de traitement 25, qui correspond désormais au flanc extérieur du déclencheur électronique. Pour se faire, la fiche de connexion de premier type 27 de la rallonge de traitement 25 s'échappe via le jour 33 et vient s'enficher dans la fiche de connexion de premier type 21 présente sur la face latérale 16 du bloc de traitement 2. Via la carte électronique 26 et la liaison filaire 40, les informations peuvent transiter entre la fiche 21 et la fiche 34. La fiche de connexion de premier type 34 présente sur la face latérale 30 de la rallonge déporte la fonctionnalité de la fiche de connexion de premier type 21 du bloc de traitement 2. Cette fonctionnalité est ainsi toujours accessible depuis l'extérieur du déclencheur. Ainsi, que le déclencheur soit configuré en tripolaire ou en tétrapolaire avec le neutre à droite, c'est-à dire devant ledit bloc de mesure 1 et ledit bloc de traitement 2 selon la direction de référence X, cette fonctionnalité reste toujours accessible.So that it is always possible to access a particular function of the trigger from the outside, the first type of connection plug 21 on the side face 16 of the treatment block 2 is offset on the side face 30 of the extension processing 25, which now corresponds to the outer edge of the electronic trigger. In order to do this, the first type connection plug 27 of the treatment extension 25 escapes via the day 33 and is plugged into the first type connection plug 21 present on the lateral face 16 of the treatment block 2 Via the electronic card 26 and the wire link 40, the information can pass between the plug 21 and the plug 34. The first type plug 34 on the side face 30 of the extension deport the functionality of the plug connector of first type 21 of the processing block 2. This functionality is thus always accessible from outside the trigger. Thus, whether the trip unit is configured as three-pole or four-pole with the right-hand neutral, that is, in front of said measurement block 1 and said processing block 2 in the reference direction X, this functionality is still accessible.

En parallèle, la fiche de connexion de second type 28 s'échappe via le jour 33 et vient s'enficher dans la fiche de connexion de second type 22 présente sur la face latérale 16 du bloc de traitement 2. Les informations de courant et de tension du neutre de la rallonge 25 sont ainsi transférées via la carte électronique 26 et la liaison filaire 29, jusqu'à la fiche 22.In parallel, the second type connection plug 28 escapes via the day 33 and is plugged into the second type connection plug 22 present on the side face 16 of the treatment block 2. The current and neutral voltage of the extension 25 are thus transferred via the electronic card 26 and the wire connection 29, to the plug 22.

La figure 13 reprend le cas de la figure 5, avec le neutre à gauche, c'est-à dire derrière ledit bloc de mesure 1 et ledit bloc de traitement 2 selon la direction de référence X, les pièces étant séparées afin d'illustrer la liaison filaire 29.The figure 13 takes up the case of the figure 5 , with the neutral on the left, ie behind said measurement block 1 and said processing block 2 in the reference direction X, the pieces being separated in order to illustrate the wire connection 29.

Dans ce cas, la seconde face latérale 17 du bloc de traitement 2, se retrouve en vis-à-vis de la première face latérale 30 de la rallonge de traitement 25.In this case, the second lateral face 17 of the processing block 2 is found opposite the first lateral face 30 of the treatment extension 25.

Il est toujours possible d'accéder à une fonction particulière du déclencheur via l'extérieur, via la fiche de connexion de premier type 21 présente sur la face latérale 16 du bloc de traitement, puisque celle-ci correspond toujours au flanc extérieur du déclencheur électronique. Ainsi, que le déclencheur soit configuré en tripolaire ou en tétrapolaire avec le neutre à gauche, c'est-à dire derrière ledit bloc de mesure 1 et ledit bloc de traitement 2 selon la direction de référence X, cette fonctionnalité reste toujours accessible, via la même fiche 21.It is always possible to access a particular function of the trigger from the outside via the first type connection plug 21 present on the lateral face 16 of the processing block, since it always corresponds to the outer edge of the electronic trigger. . Thus, whether the trip unit is configured as three-pole or four-pole with the neutral on the left, ie behind said measurement block 1 and said processing block 2 in the reference direction X, this functionality is still accessible via the same card 21.

La fiche de connexion de second type 28 s'échappe via le jour 32 et vient s'enficher dans la fiche de connexion de second type 42 présente sur la face latérale 17 du bloc de traitement 2. Les informations de courant et de tension du neutre de la rallonge 25 sont ainsi transférées via la carte électronique 26 et la liaison filaire 29, jusqu'à la fiche 42.The second type connection plug 28 escapes via the day 32 and is plugged into the second type connector plug 42 on the side face 17 of the treatment block 2. The current and voltage information of the neutral of the extension 25 are thus transferred via the electronic card 26 and the wire link 29, to the plug 42.

Dans ce cas, les fiches de connexion de premier type 27,34 sont inutilisées pour cette configuration tétrapolaire avec le neutre à gauche, c'est-à dire derrière ledit bloc de mesure 1 et ledit bloc de traitement 2 selon la direction de référence X. En particulier, la fiche 27 et sa liaison filaire 40 sont rangées dans la rallonge 25.In this case, the first type connection plugs 27, 34 are unused for this four-pole configuration with the neutral on the left, ie behind said measurement block 1 and said processing block 2 in the reference direction X In particular, the plug 27 and its wire link 40 are stored in the extension 25.

La rallonge de mesure 24 est illustrée plus précisément aux figures 6a et 6b. Elle se fixe au bloc de mesure 1 au moyen d'une pièce support 35, soit à droite, c'est-à dire devant ledit bloc de mesure 1 et ledit bloc de traitement 2 selon la direction de référence X, comme illustré en figure 10, soit à gauche, c'est-à dire derrière ledit bloc de mesure 1 et ledit bloc de traitement 2 selon la direction de référence X, comme illustré en figure 11.The measuring extension 24 is illustrated more precisely in Figures 6a and 6b . It is fixed to the measurement block 1 by means of a support piece 35, or to the right, that is to say in front of said measurement block 1 and said processing block 2 in the reference direction X, as illustrated in FIG. figure 10 , or to the left, that is to say behind said measurement block 1 and said processing block 2 in the reference direction X, as illustrated in FIG. figure 11 .

Cette pièce support 35 consiste en une pièce symétrique, comprenant une paroi de séparation du bloc de mesure 1 par rapport à la rallonge de mesure 24.This support piece 35 consists of a symmetrical part comprising a partition wall of the measuring block 1 with respect to the measuring extension 24.

Elle est conçue dans un matériau isolant électriquement, par exemple du plastique, afin d'isoler électriquement le bloc de mesure 1 par rapport à la rallonge de mesure 24.It is designed in an electrically insulating material, for example plastic, to electrically isolate the measuring block 1 from the measuring extension 24.

La paroi de séparation est dotée de part et d'autre de moyens d'accroche pour se fixer d'un côté au bloc de mesure 1, et de l'autre côté à la rallonge mesure 24. Plus précisément, en partie supérieure, deux pattes 36,37 s'étendent perpendiculairement de la paroi de séparation. En partie inférieure, deux pattes 38.39 s'étendent perpendiculairement de la paroi de séparation. Ces pattes 36,37,38,39 présentent toutes une encoche dans laquelle peuvent se glisser un retour saillant du bloc de mesure 1 et de la rallonge de mesure 24.The partition wall is provided on each side with hooking means for fixing on one side to the measuring block 1, and on the other side to the measuring extension 24. More precisely, in the upper part, two tabs 36,37 extend perpendicularly from the partition wall. In the lower part, two legs 38.39 extend perpendicularly of the partition wall. These tabs 36, 37, 38, 39 all have a notch in which a protruding return of the measuring block 1 and the measuring extension 24 can be seen.

Dans l'exemple présenté en figure 10, les pattes 37 et 39 sont accrochées au bloc de mesure 1, et les pattes 36 et 38 sont accrochées à la rallonge de mesure 24.In the example presented in figure 10 the tabs 37 and 39 are attached to the measuring block 1, and the tabs 36 and 38 are attached to the measuring extension 24.

Dans l'exemple présenté en figure 11, les pattes 36 et 38 sont accrochées au bloc de mesure 1, et les pattes 37 et 39 sont accrochées à la rallonge de mesure 24.In the example presented in figure 11 the tabs 36 and 38 are attached to the measuring block 1, and the tabs 37 and 39 are attached to the measuring extension 24.

La rallonge de traitement 25 est fixée à la rallonge de mesure 24. Pour se faire, deux pattes 43 en forme de L, visibles en figure 7, s'étendent de la face de raccordement 41 de la rallonge de traitement 25 en direction de la rallonge mesure 24. Ces deux pattes 43 sont disposées de part et d'autre du connecteur femelle 13 et sont aptes à s'insérer par glissement dans deux évidements 44 de forme correspondante prévus à cet effet de part et d'autre du connecteur mâle 8 de la rallonge de mesure 24, comme illustré en figure 6a. Ces pattes 43 permettent un blocage en translation d'une rallonge par rapport à l'autre dans deux directions perpendiculaires à la direction d'emboîtement des pattes 43 dans les évidements 44.The processing extension 25 is fixed to the measuring extension 24. To do this, two tabs 43 in the shape of an L, visible in figure 7 , extend from the connecting face 41 of the processing extension 25 towards the measuring extension 24. These two tabs 43 are disposed on either side of the female connector 13 and are able to slide in two recesses 44 of corresponding shape provided for this purpose on either side of the male connector 8 of the measuring extension 24, as illustrated in FIG. figure 6a . These tabs 43 allow locking in translation of an extension relative to the other in two directions perpendicular to the interlocking direction of the tabs 43 in the recesses 44.

En ce qui concerne la description ci-dessus, les relations dimensionnelles optimales pour les parties de l'invention, en incluant les variations de taille, de formes, de fonction et de modes de fonctionnement, d'assemblage et d'utilisation, sont considérées comme apparentes et évidentes pour l'homme du métier, et toutes les relations équivalentes à ce qui est illustré dans les dessins et ce qui est décrit dans le mémoire sont censées être incluses dans la présente invention.With respect to the above description, the optimal dimensional relationships for the parts of the invention, including variations in size, shapes, function and modes of operation, assembly and use, are considered as apparent and obvious to those skilled in the art, and all relationships equivalent to what is illustrated in the drawings and what is described in the specification are meant to be included in the present invention.
