II est connu d'associer un module de protection contre la foudre à un module de coupure. Le module de coupure est calibré de manière à protéger une installation lorsque le module de protection contre la foudre se place en court-circuit suite à un défaut de fonctionnement. Le module de coupure peut être notamment un déconnecteur tel un disjoncteur et/ou un fusible. La norme impose d'associer un déconnecteur au module de protection contre la foudre.It is known to associate a lightning protection module with a breaking module. The cut-off module is calibrated to protect an installation when the lightning protection module is short-circuited due to a malfunction. The breaking module can be in particular a disconnector such as a circuit breaker and / or a fuse. The standard requires associating a disconnector with the lightning protection module.

L'installateur réalise alors le câblage électrique entre les deux dispositifs électriques.The combination of the lightning protection module and the breaking module is generally performed by the installer.

Enfin le mauvais positionnement électrique du module de coupure par rapport au module de protection contre la foudre est responsable d'une réduction des performances de l'ensemble et la protection de l'installation peut être mal assurée ou détériorée.Finally, the poor electrical positioning of the cut-off module with respect to the lightning protection module is responsible for a reduction in the performance of the assembly and the protection of the installation can be poorly secured or deteriorated.

Comme représenté sur les
Selon un mode de réalisation préférentiel de l'invention, l'interface de déclenchement 1 comporte des premiers moyens mécaniques de couplage 108 adaptés pour collaborer avec un module de protection 2 contre des surtensions.According to a preferred embodiment of the invention, the
L'interface de déclenchement 1 comporte aussi des moyens mécaniques d'actionnement à propre énergie 13 pouvant passer d'un état de fonctionnement armé à un état de fonctionnement déclenché pour actionner l'ouverture dudit au moins un module de coupure électrique 3. L'interface de déclenchement 1 comporte des seconds moyens mécaniques de couplage 110 adaptés pour actionner le module de coupure électrique 3.The
Le passage d'un état de fonctionnement armé à un état de fonctionnement déclenché peut être provoqué notamment par un défaut généré par au moins un élément de protection 2. Ce défaut de fonctionnement est transmis aux dits moyens d'actionnement à propre énergie 13 par l'intermédiaire des moyens premiers mécanique de couplage 108. Les moyens mécaniques d'actionnement à propre énergie 13 passent d'un état de fonctionnement armé à un état de fonctionnement déclenché sous l'action dudit moyen de détente 14 ré-armable. Avantageusement, le moyen de détente 14 ré-armable comporte un ressort.The transition from an armed operating state to a triggered operating state can be caused in particular by a fault generated by at least one
Selon un mode de réalisation représenté sur les
Le moyen de détente 14 ré-armable est relié à une platine 101 rotative. La platine 101 rotative est maintenue dans une position armée par la barre de déclenchement mobile 102. Selon ce mode de réalisation, moyens de blocage 112 du levier de déclenchement 107 collaborent avec la barre de déclenchement mobile 102 pour la bloquer dans la position armée. Le levier de déclenchement 107 des premiers moyens mécaniques de couplage 108 se trouve dans une première position de fonctionnement.The re-arming means 14 is connected to a
Dans une seconde position de fonctionnement du levier de déclenchement 107, les moyens de blocage 112 dudit levier ne collaborent pas avec la barre de déclenchement mobile 102. Le mouvement de la barre de déclenchement 102 est alors libre et ne peut plus bloquer la platine 101 dans la position armée. Le réarmement des moyens mécaniques d'actionnement à propre énergie 13 et du moyen de détente 14 ré-armable est alors rendu impossible.In a second operating position of the triggering
Ainsi, lorsqu'un défaut de fonctionnement d'au moins un module de protection 2 est présent, les premiers moyens mécaniques de couplage 108 se positionnent dans la deuxième position de fonctionnement et de ce fait interdisent un réarmement des moyens mécaniques d'actionnement à propre énergie 13 et du moyen de détente 14 ré-armable tant que le défaut persiste.Thus, when a malfunction of at least one
Lorsque la platine 101 et le moyen de détente 14 ré-armable sont maintenus simultanément dans une position armée grâce à la barre de déclenchement 102, l'interface de déclenchement 1 est alors dans un état de fonctionnement armé et prête à recevoir un ordre déclenchement d'au moins un module de protection 2 contre des surtensions et/ou d'au moins un module de coupure 3 électrique.When the
De préférence, l'interface de déclenchement 1 comporte des moyens de réarmement 17 du moyen de détente 14 ré-armable. Les moyens de réarmement 17 comprennent une manette pouvant se placer selon deux positions respectivement associées aux états de fonctionnement des moyens mécaniques d'actionnement à propre énergie 13.Preferably, the
Dans un mode particulier de réalisation de l'invention telle que représenté notamment aux
L'interface de déclenchement 1 est généralement placée dans un état de fonctionnement armé en actionnant la manette 17.The
Selon un exemple de réalisation présenté à les
L'interface de déclenchement 1 comporte de préférence des moyens de visualisation 16 actionnés par les moyens mécaniques d'actionnement à propre énergie 13 pour indiquer l'état de fonctionnement de ladite interface. Selon un mode particulier de réalisation de l'invention, les moyens de visualisation 16 comportent une liaison mécanique 18 destinée à être couplée avec un organe de manoeuvre 36 d'au moins un appareil de coupure 3 électrique pour indiquer l'état de coupure dudit appareil de coupure.The tripping
L'interface de déclenchement comporte des moyens d'information à distance de l'état de fonctionnement de l'interface de déclenchement 1. Selon un exemple de réalisation présenté aux
L'invention est aussi relative à un module de protection 2 contre les surtensions destiné à être couplé à une interface de déclenchement 1. Le module de protection 2 comporte une palette de commande 201 destinée à collaborer directement avec les premiers moyens mécaniques de couplage 108 de l'interface de déclenchement 1. La palette de commande 201 est contenue dans un bloc modulaire 21 dans lequel est connecté au moins un limiteur de surtension 27 à éléments non linéaires variables avec la tension. Ledit au moins un limiteur surtension 27 est connecté à des plages de raccordement 23, 24 dudit bloc 21.The invention also relates to a
A titre d'exemple, le limiteur de surtension 27 comporte une varistance.For example, the
Selon l'invention, le limiteur de surtension 27 est disposé dans une cartouche débrochable 25, la dite cartouche 25 est reliée au bloc modulaire 21 par des moyens d'assemblage électriques et mécaniques 201, 202, 203, 204, 205 et 206.According to the invention, the
Les moyens d'assemblage mécaniques 201, 202, 203, 204, 205 et 206 sont reliés aux moyens mécaniques d'actionnement à propre énergie 13 via la palette de commande 201 et les premiers moyens mécaniques de couplage 108. Le débrochage de la cartouche 25 entraîne l'envoi d'un défaut de fonctionnement aux moyens mécaniques d'actionnement à propre énergie 13 qui se placent dans un état de fonctionnement déclenché.The mechanical assembly means 201, 202, 203, 204, 205 and 206 are connected to the self-powered mechanical actuating means 13 via the
Le module de protection 2 peut se mettre en défaut pour essentiellement deux raisons. Premièrement, une cartouche débrochable 25 est retirée de son bloc modulaire 21, on parlera de défaut mécanique. Deuxièmement, un limiteur de surtension 27 se place en court-circuit, on parlera de défaut électrique.The
Selon un mode de réalisation de l'invention, le limiteur de surtension 27 est reliée au du bloc modulaire 21 par au moins une liaison fusible 26. Un défaut électrique, une mise en court-circuit ou un échauffement du limiteur de surtension 27 provoquent la fusion de l'élément fusible 26 reliant le limiteur de surtension 27 à une des plages de raccordement 23, 24 du bloc modulaire 21. Une fusion de ladite liaison fusible 26 entraîne l'envoi d'un défaut de fonctionnement aux moyens mécaniques d'actionnement à propre énergie 13. La fusion de la liaison thermique 26 provoque une rupture mécanique agissant sur les moyens mécaniques d'actionnement à propre énergie 13 via les moyens d'assemblage mécaniques 201, 202, 203, 204 et 205.According to one embodiment of the invention, the
Lorsque le module de protection 2 se met en défaut, le fonctionnement de l'interface de déclenchement 1 est le suivant. Comme représenté sur les
L'ordre d'ouverture ou de déclenchement reçu par le module de coupure 3 placé en contact direct avec l'interface de déclenchement 1 est ensuite transmis de manière traditionnelle aux autres modules de coupure 3. On parlera de déclenchement en cascade.The opening or tripping order received by the
Dans le cas de défaut mécanique, le doigt 202 est libéré et la palette de commande 201 est entrainée en rotation sous l'action d'une force générée par le moyen de détente 203.In the case of mechanical defect, the
Tant que le défaut présent d'un module de protection 2 n'a pas été résorbé, au moins un doigt 202 restera déplacé, notamment en position haute. La palette de commande 201 est alors gardée en position de défaut à l'aide du premier ressort 203 et, les premiers moyens mécaniques de couplage 108 sont maintenus dans la seconde position de fonctionnement. Ainsi, les moyens de blocage 112 du levier de déclenchement 107 ne peuvent pas collaborer avec la barre de déclenchement bobine 102 et empêchent tous réarmements des moyens mécaniques d'actionnement à propre énergie 13 de l'interface de déclenchement 1. Le réarmement de l'interface de déclenchement et du ou des modules de coupure associés est rendu impossible.As long as the present defect of a
Pour remettre le système en état de fonctionnement armé, il faudra donc supprimer tous les défauts de fonctionnement, notamment en remettant la ou les cartouches 25 en position. La palette de commande 201 qui est alors soumise à l'effort d'un second ressort 205, retrouve une position de fonctionnement armé. Les premiers moyens mécaniques de couplage 108 se positionnent dans la première position de fonctionnement et autorisent le réarmement de l'interface de déclenchement 1.To put the system in the armed operating state, it will be necessary to remove all malfunctions, including putting the cartridge (s) 25 in position. The
