Description

L'invention concerne le domaine des ensembles de protection contre les surtensions.The invention relates to the field of surge protection assemblies.

Dans le domaine des équipements électriques résidentiels ou tertiaires, l'on connaît des appareils électriques de protection modulaires du type disjoncteur modulaire couramment appelé par sa désignation anglaise MCB signifiant Miniature Circuit Breaker ou du type parafoudre modulaire couramment appelé par sa désignation anglaise SPD signifiant Surge Protection Device. Un tel disjoncteur modulaire permet de réaliser une protection contre les défauts de type court-circuit et de type surcharge. En outre, un tel parafoudre modulaire permet de réaliser une protection contre les défauts de type surtension par exemple due à la foudre.In the field of residential or tertiary electrical equipment, we know modular electrical protection devices of the modular circuit breaker type commonly called by its English designation MCB meaning Miniature Circuit Breaker or of the modular surge arrester type commonly called by its English designation SPD meaning Surge Protection Device. Such a modular circuit breaker provides protection against short-circuit and overload type faults. In addition, such a modular surge arrester provides protection against overvoltage type faults, for example due to lightning.

La publication EP1447831A1 illustre qu'il est connu de coupler un disjoncteur modulaire et un parafoudre modulaire pour créer un ensemble de protection contre les surtensions. Notamment, un disjoncteur modulaire comprenant une ligne de phase et une ligne de neutre peut être couplé à un parafoudre comprenant une ligne de phase, une ligne de neutre et une ligne de terre. Pour ce faire, il est connu de prévoir des moyens de raccordement électrique et mécanique qui sont intégrés dans le parafoudre et qui peuvent coopérer électriquement avec une extrémité du disjoncteur pour raccorder les lignes de phase entre elles et pour raccorder les lignes de neutre entre elles. Cette configuration présente l'inconvénient de nécessiter de modifier la forme du boîtier du parafoudre.The publication EP1447831A1 illustrates that it is known to couple a modular circuit breaker and a modular surge arrester to create a surge protection assembly. In particular, a modular circuit breaker comprising a phase line and a neutral line can be coupled to a surge arrester comprising a phase line, a neutral line and an earth line. To do this, it is known to provide electrical and mechanical connection means which are integrated into the surge arrester and which can cooperate electrically with one end of the circuit breaker to connect the phase lines together and to connect the neutral lines together. This configuration has the disadvantage of requiring modification of the shape of the surge arrester housing.

La présente invention a pour but de proposer une solution alternative qui évite de modifier la forme du boîtier du parafoudre.The present invention aims to propose an alternative solution which avoids modifying the shape of the lightning arrester housing.

L'invention concerne un ensemble de protection contre les surtensions comprenant au moins :

  • un disjoncteur modulaire 1 comprenant au moins une première ligne de phase comprenant au moins une première borne de connexion de phase et une deuxième borne de connexion de phase 2, une première ligne de neutre comprenant au moins une première borne de connexion de neutre et une deuxième borne de connexion de neutre 3 et un premier boîtier 4,
  • un parafoudre modulaire 5 comprenant au moins une deuxième ligne de phase comprenant au moins une troisième borne de connexion de phase 6, une deuxième ligne de neutre comprenant au moins une troisième borne de connexion de neutre 7, une première ligne de terre comprenant au moins une première borne de connexion de terre 8 et un deuxième boîtier 9,
  • des moyens de raccordement électrique et mécanique comprenant au moins un premier conducteur électrique de phase 10 et un deuxième conducteur électrique de neutre 11.
The invention relates to a surge protection assembly comprising at least:
  • a modular circuit breaker 1 comprising at least a first phase line comprising at least a first phase connection terminal and a second phase connection terminal 2, a first neutral line comprising at least a first neutral connection terminal and a second neutral connection terminal 3 and a first housing 4,
  • a modular surge arrester 5 comprising at least a second phase line comprising at least a third phase connection terminal 6, a second neutral line comprising at least a third neutral connection terminal 7, a first earth line comprising at least a first earth connection terminal 8 and a second housing 9,
  • electrical and mechanical connection means comprising at least a first phase electrical conductor 10 and a second neutral electrical conductor 11.

Conformément à l'invention, ledit ensemble de protection est caractérisé :

  • en ce qu'il comprend en outre un module de raccordement 12 comprenant les moyens de raccordement électrique et mécanique comprenant le premier conducteur électrique de phase 10 configuré pour être raccordé d'une part à la deuxième borne de connexion de phase 2 du disjoncteur modulaire 1 et d'autre part à la troisième borne de connexion de phase 6 du parafoudre modulaire 5, le deuxième conducteur électrique de neutre 11 configuré pour être raccordé d'une part à la deuxième borne de connexion de neutre 3 du disjoncteur modulaire 1 et d'autre part pour être raccordé à la troisième borne de connexion de neutre 7 du parafoudre modulaire 5 et une deuxième borne de connexion de terre 13 comprenant une entrée 14 destinée à être raccordée avec la première borne de connexion de terre 8 du parafoudre modulaire 5 et une sortie 15, et un troisième boîtier 16,
  • en ce que le disjoncteur modulaire 1, le parafoudre modulaire 5 et le module de raccordement 12 forment respectivement une première entité délimitée par le premier boîtier 4, une deuxième entité délimitée par le deuxième boîtier 9 et une troisième entité délimitée par le troisième boîtier 16.
According to the invention, said protective assembly is characterized:
  • in that it further comprises a connection module 12 comprising the electrical and mechanical connection means comprising the first phase electrical conductor 10 configured to be connected on the one hand to the second phase connection terminal 2 of the modular circuit breaker 1 and on the other hand to the third phase connection terminal 6 of the modular surge arrester 5, the second neutral electrical conductor 11 configured to be connected on the one hand to the second neutral connection terminal 3 of the modular circuit breaker 1 and on the other hand to be connected to the third neutral connection terminal 7 of the modular surge arrester 5 and a second earth connection terminal 13 comprising an input 14 intended to be connected with the first earth connection terminal 8 of the modular surge arrester 5 and an output 15, and a third housing 16,
  • in that the modular circuit breaker 1, the modular surge arrester 5 and the connection module 12 respectively form a first entity delimited by the first housing 4, a second entity delimited by the second housing 9 and a third entity delimited by the third housing 16.

Avantageusement, cette solution permet de proposer un ensemble de protection contre les surtensions sous la forme de trois entités distinctes, avec un disjoncteur modulaire 1 et un parafoudre modulaire 5 qui peuvent être reliés entre eux électriquement et mécaniquement par l'ajout d'un module de raccordement 12 qui est une entité distincte et séparée d'une part du disjoncteur modulaire 1 et d'autre part du parafoudre modulaire 5. Autrement dit, le module de raccordement 12 ne fait ni partie du disjoncteur modulaire 1, ni du parafoudre modulaire 5. Ainsi, il n'est pas nécessaire de modifier l'architecture des premier et deuxième boitiers 4, 9 comme c'est notamment le cas dans l'art antérieur. En outre, grâce à cette configuration qui inclut dans l'ensemble un module de raccordement 12 intégrant la possibilité de raccorder le parafoudre modulaire 5 à un potentiel de terre via la première borne de connexion de terre 8 et la deuxième borne de connexion de terre 13, l'utilisateur n'a pas à acheter séparément une pièce supplémentaire permettant de connecter le parafoudre modulaire 5 au potentiel de terre. En résumé, le module de raccordement 12 permet de raccorder électriquement les première et deuxième lignes de phase entre elles, les première et deuxième lignes de neutre entre elles et de raccorder la première ligne de terre du parafoudre modulaire 5 à un potentiel de terre via la sortie 15.Advantageously, this solution makes it possible to propose an overvoltage protection assembly in the form of three separate entities, with a modular circuit breaker 1 and a modular surge arrester 5 which can be connected to each other electrically and mechanically by the addition of a connection module 12 which is a distinct entity and separate on the one hand from the modular circuit breaker 1 and on the other hand from the modular surge arrester 5. In other words, the connection module 12 is neither part of the modular circuit breaker 1 nor of the modular surge arrester 5. Thus, it is not necessary to modify the architecture of the first and second boxes 4, 9 as is notably the case in the prior art. In addition, thanks to this configuration which includes in the assembly a connection module 12 integrating the possibility of connecting the modular surge arrester 5 to an earth potential via the first earth connection terminal 8 and the second earth connection terminal 13, the user does not have to separately purchase an additional part for connecting the modular surge protector 5 to the earth potential. In summary, the connection module 12 makes it possible to electrically connect the first and second phase lines to each other, the first and second neutral lines to each other and to connect the first earth line of the modular surge protector 5 to an earth potential via the output 15.

De préférence et comme l'illustrent les figures 3 à 4 et 15 à 16, dans une position assemblée PA le disjoncteur modulaire 1 et le parafoudre modulaire 5 sont raccordés par le module de raccordement 12 pour former une unité monobloc 17 et le premier conducteur électrique de phase 10 est raccordé d'une part à la deuxième borne de connexion de phase 2 du disjoncteur modulaire 1 et d'autre part à la troisième borne de connexion de phase 6 du parafoudre modulaire 5, le deuxième conducteur électrique de neutre 11 est raccordé d'une part à la deuxième borne de connexion de neutre 3 du disjoncteur modulaire 1 et d'autre part à la troisième borne de connexion de neutre 7 du parafoudre modulaire 5, et l'entrée 14 de la deuxième borne de connexion de terre 13 est raccordée à la première borne de connexion de terre 8 du parafoudre modulaire 5.Preferably and as illustrated by the figures 3 to 4 And 15 to 16 , in an assembled position PA the modular circuit breaker 1 and the modular surge arrester 5 are connected by the connection module 12 to form a single-piece unit 17 and the first phase electrical conductor 10 is connected on the one hand to the second phase connection terminal 2 of the modular circuit breaker 1 and on the other hand to the third phase connection terminal 6 of the modular surge arrester 5, the second neutral electrical conductor 11 is connected on the one hand to the second neutral connection terminal 3 of the modular circuit breaker 1 and on the other hand to the third neutral connection terminal 7 of the modular surge arrester 5, and the input 14 of the second earth connection terminal 13 is connected to the first earth connection terminal 8 of the modular surge arrester 5.

Avantageusement, l'ensemble de protection contre les surtensions présente une architecture compacte dans la position assemblée PA puisqu'elle forme une unité monobloc 17 par assemblage des trois entités à savoir la première entité, la deuxième entité et la troisième entité.Advantageously, the surge protection assembly has a compact architecture in the assembled position PA since it forms a single-piece unit 17 by assembling the three entities, namely the first entity, the second entity and the third entity.

En outre, l'ensemble de protection contre les surtensions présente l'avantage d'être montable et démontable de façon réversible, il est ainsi possible de passer de la position démontée PD, dans laquelle les trois entités ne sont pas raccordées par l'intermédiaire du module de raccordement 12, à la position assemblée PA et inversement.Furthermore, the surge protection assembly has the advantage of being reversibly mountable and dismountable, it is thus possible to move from the dismounted position PD, in which the three entities are not connected via the connection module 12, to the assembled position PA and vice versa.

Avantageusement, la languette saillante 30 présente l'avantage de pouvoir s'insérer dans l'entrée 14 de la deuxième borne de connexion de terre 13 du module de raccordement 12. La sortie 15 de la deuxième borne de connexion de terre 13 peut ensuite être raccordée à un potentiel de terre d'une installation électrique (non représentée). Ainsi, cette configuration permet de raccorder électriquement la première ligne de terre du parafoudre modulaire 5 au potentiel de terre d'une installation électrique.Advantageously, the projecting tab 30 has the advantage of being able to be inserted into the input 14 of the second earth connection terminal 13 of the connection module 12. The output 15 of the second earth connection terminal 13 can then be connected to an earth potential of an electrical installation (not shown). Thus, this configuration makes it possible to electrically connect the first earth line of the modular surge arrester 5 to the earth potential of an electrical installation.

De préférence et comme l'illustrent les figures 7 à 9 et 19 à 21, le premier conducteur électrique de phase 10 comprend une première extrémité 31 configurée pour être raccordée à la deuxième borne de connexion de phase 2 du disjoncteur modulaire 1 et une deuxième extrémité 32 configurée pour être raccordée à la troisième borne de connexion de phase 6 du parafoudre modulaire 5 et le deuxième conducteur électrique de neutre 11 comprend une troisième extrémité 33 configurée pour être raccordée à la deuxième borne de connexion de neutre 3 du disjoncteur modulaire 1 et une quatrième extrémité 34 configurée pour être raccordée à la troisième borne de connexion de neutre 7 du parafoudre modulaire 5.Preferably and as illustrated by the figures 7 to 9 And 19 to 21 , the first phase electrical conductor 10 comprises a first end 31 configured to be connected to the second phase connection terminal 2 of the modular circuit breaker 1 and a second end 32 configured to be connected to the third phase connection terminal 6 of the modular surge arrester 5 and the second neutral electrical conductor 11 comprises a third end 33 configured to be connected to the second neutral connection terminal 3 of the modular circuit breaker 1 and a fourth end 34 configured to be connected to the third neutral connection terminal 7 of the modular surge arrester 5.

De préférence et comme l'illustrent les figures, le troisième boîtier 16 présente une forme globalement parallélépipèdique avec deux faces principales respectivement une troisième face principale gauche 35 et une troisième face principale droite 36, et des troisièmes faces latérales s'étendant de l'une à l'autre des faces principales, à savoir une troisième face arrière 37, une troisième face avant 38, une troisième face inférieure 39 et une troisième face supérieure 40, la largeur du module de raccordement 12 correspondant à la distance modulaire du module de raccordement dm entre la troisième face principale gauche 35 et la troisième face principale droite 36, correspond à un multiple d'une valeur normalisée, appelée module, dont la valeur est sensiblement égale à 18 millimètres, la première extrémité 31, la deuxième extrémité 32, la troisième extrémité 33 et la quatrième extrémité 34 étant saillantes de la troisième face supérieure 40, et l'entrée 14 de la deuxième borne de connexion de terre 13 débouchant de la troisième face supérieure 40 et la sortie 15 de la deuxième borne de connexion de terre 13 débouchant de la troisième face inférieure 39.Preferably and as illustrated in the figures, the third housing 16 has a generally parallelepiped shape with two main faces, respectively a third left main face 35 and a third right main face 36, and third lateral faces extending from one to the other of the main faces, namely a third rear face 37, a third front face 38, a third lower face 39 and a third upper face 40, the width of the connection module 12 corresponding to the modular distance of the connection module dm between the third left main face 35 and the third right main face 36, corresponds to a multiple of a standardized value, called module, the value of which is substantially equal to 18 millimeters, the first end 31, the second end 32, the third end 33 and the fourth end 34 being projecting from the third upper face 40, and the input 14 of the second earth connection terminal 13 emerging from the third upper face 40 and the output 15 of the second earth connection terminal 13 emerging from the third lower face 39.
