Description

MODULE ENTREE A CONNEXION AUTOPORTEE DOMAINE TECHNIQUE  INPUT CONNECTION MODULE AUTOPORTEE TECHNICAL FIELD
L'invention concerne le domaine de l'automatisation dans les systèmes de transmission et distribution électrique. En particulier, l'invention est relative aux éléments de contrôle et/ou commande, notamment de protection de réseau électrique, recevant des informations logiques tout ou rien qui permettent de visualiser la position d'appareils, notamment haute tension comme des sectionneurs, disjoncteurs, ou autres, et éventuellement de réaliser des actions automatiques à partir de ces informations. The invention relates to the field of automation in transmission systems and electrical distribution. In particular, the invention relates to the control and / or control elements, in particular electrical network protection, receiving digital all or nothing information that can display the position of devices, including high voltage such as disconnectors, circuit breakers, or others, and possibly perform automatic actions from this information.
ETAT DE LA TECHNIQUE STATE OF THE ART
Les réseaux de distribution électrique comprennent de nombreux appareillages, pour protéger et exploiter la ligne (disjoncteurs, sectionneurs), pour transformer la tension, pour transformer le courant en valeurs mesurables par les équipements de contrôle/commande et de protection... Ces appareillages primaires sont habituellement pilotés par des systèmes d'automatisation qui comprennent des appareillages dits secondaires qui acquièrent des informations issues de l'appareillage primaire ou de tout autre équipement associé à son fonctionnement comme un capteur ; par exemple, les appareillages secondaires peuvent comprendre des calculateurs de contrôle/commande ou des relais de protection digitaux. Ces dispositifs électroniques dits intelligents IED (pour « Intelligent Electronic Device » selon la terminologie anglo-saxonne) sont aptes à recevoir des informations, généralement du type tout ou rien DI (pour « Digital Input » selon la terminologie anglo-saxonne) relatives aux appareillages primaires, par exemple du type : disjoncteur fermé, disjoncteur ouvert, sectionneur fermé, sectionneur ouvert, seuil de densité du gaz d'isolation bas,... Electrical distribution networks include many devices, to protect and operate the line (circuit breakers, disconnectors), to transform the voltage, to transform the current into measurable values by the control / command and protection equipment ... These primary devices are usually driven by automation systems that include so-called secondary devices that acquire information from the primary switchgear or other equipment associated with its operation as a sensor; for example, the secondary devices may include control / control computers or digital protection relays. These so-called intelligent electronic devices IED (for "Intelligent Electronic Device" according to the English terminology) are able to receive information, usually all-or-nothing type (for "Digital Input" according to English terminology) relating to equipment primary, for example of the type: closed circuit-breaker, open circuit-breaker, closed disconnector, open disconnector, low insulation gas density threshold, ...
A cette fin, tel qu'illustré en figure 1A, un IED 1 comprend une unité centrale 2, typiquement installée dans un coffret basse tension, qui comprend des organes d'acquisition de signalisation externe 4 raccordés à des connecteurs 6 auxquels sont branchés des fils 8, usuellement en cuivre de section de l'ordre de 1,5 mm , qui les relient à des équipements externes 10, par exemple des disjoncteurs ou sectionneurs du réseau de distribution électrique. Classiquement, le coffret de l'IED 1 est câblé en usine et il comprend des borniers de jonction 12 à l'autre extrémité des fils 8 raccordés aux connecteurs 6 de l'unité centrale 2 ; les borniers de jonction 12 sont adaptés pour le raccordement aux appareillages externes 10 par des fils de cuivre 14, souvent de section plus importante que les fils 8 entre les borniers 12 et l'unité centrale 2 ; les borniers 12 peuvent par exemple être adaptés pour une connexion vissée. For this purpose, as illustrated in FIG. 1A, an IED 1 comprises a central unit 2, typically installed in a low voltage cabinet, which comprises external signaling acquisition members 4 connected to connectors 6 to which wires are connected. 8, usually copper section of the order of 1.5 mm, which connect to external equipment 10, for example circuit breakers or disconnectors of the network. electrical distribution. Conventionally, the cabinet of the IED 1 is wired in the factory and it comprises terminal blocks 12 at the other end of the son 8 connected to the connectors 6 of the central unit 2; the junction terminal blocks 12 are adapted for connection to the external equipment 10 by copper wires 14, often of larger section than the son 8 between the terminal blocks 12 and the central unit 2; the terminal blocks 12 may for example be adapted for a screw connection.
Au vu de la complexité du raccordement de telles unités centrales 2, du coût généré par les fils de cuivre 8 eux-mêmes et du coût associé au temps de câblage, pour le domaine de l'automatisation, des IED modulaires ont été développés, tel que schématisé en figure 1B. Typiquement, l'IED comprend une embase 16 fixée dans l'armoire basse tension, classiquement sur un rail, assurant la fonction de borne de jonction avec les fils 14 de raccordement aux équipements 10. Dans cette embase 16 peuvent être enfichés des boîtiers 18 qui contiennent des organes d'acquisition de signalisation externe 20, qui sont reliés aux bornes de jonction de l'embase 16 par des broches 22. Les organes d'acquisition de signalisation externe 20 transmettent l'état présent ou absent de l'équipement 10 au travers d'une communication, typiquement numérique, 24 qui relie l'embase 16 à l'unité centrale 2' : pour permettre la communication entre l'unité centrale 2' et le module débrochable 18, un connecteur de communication 26 est prévu. La communication d'information 24, 26 transmet en outre l'alimentation nécessaire au fonctionnement des organes d'acquisition de signalisation externe 20 ; éventuellement, des voyants de signalisation alimentés en fonction de l'état des organes d'acquisition 20 peuvent également être installés sur le boîtier 18. Ainsi, lorsque le module enfichable 18 est inséré dans l'embase 16, une double connexion se met en place : les bornes de raccordement sont reliées par un connecteur 22 aux organes d'acquisition de signalisation externe 20, et le connecteur de communication 26 permet la transmission des signaux de communication via la connexion 24. Cependant, lorsque le module 18 est débroché, les organes d'acquisition de signalisation externe 20 ne sont plus opérationnels puisque la communication numérique entre l'unité centrale 2' et le boîtier 18 est interrompue : il n'est alors pas possible de tester facilement le bon fonctionnement de ce module 18. EXPOSE DE L'INVENTION In view of the complexity of the connection of such central units 2, the cost generated by the copper wires 8 themselves and the cost associated with the wiring time, for the field of automation, modular IEDs have been developed, such as that schematized in Figure 1B. Typically, the IED comprises a base 16 fixed in the low-voltage cabinet, conventionally on a rail, acting as a terminal terminal with the wires 14 for connection to the equipment 10. In this base 16 can be plugged boxes 18 which contain external signal acquisition members 20, which are connected to the junction terminals of the base 16 by pins 22. The external signal acquisition means 20 transmit the present or absent state of the equipment 10 to the through a communication, typically digital, 24 which connects the base 16 to the central unit 2 ': to allow communication between the central unit 2' and the withdrawable module 18, a communication connector 26 is provided. The information communication 24, 26 further transmits the power required for the operation of the external signal acquisition means 20; optionally, signaling lights powered according to the state of the acquisition members 20 may also be installed on the housing 18. Thus, when the plug-in module 18 is inserted into the base 16, a double connection is put in place the connection terminals are connected by a connector 22 to the external signaling acquisition members 20, and the communication connector 26 enables the transmission of the communication signals via the connection 24. However, when the module 18 is unplugged, the devices external signal acquisition 20 are no longer operational since the digital communication between the central unit 2 'and the housing 18 is interrupted: it is then not possible to easily test the proper operation of this module 18. SUMMARY OF THE INVENTION
Parmi autres avantages, l'invention vise à pallier des inconvénients des équipements de protection ou de contrôle/commande existants, en ce que les entrées d'acquisition d'informations en provenance des appareils externes sont déportées sur les modules d'interface et non plus intégrées dans l'unité centrale ou l'embase. Ainsi, le module reste entièrement opérationnel lorsqu'il est débroché et son bon fonctionnement peut notamment être vérifié, par exemple par mise en place sur un banc de test simulant la présence ou l'absence des signalisations externes. Among other advantages, the invention aims to overcome the drawbacks of existing protection or control / command equipment, in that the information acquisition inputs from the external devices are deported to the interface modules and no longer integrated in the central unit or the base. Thus, the module remains fully operational when disconnected and its proper operation can be verified, for example by setting up a test bench simulating the presence or absence of external signals.
En particulier, l'invention est relative à un groupe de modules DI, notamment aptes à recevoir des informations relatives à des appareils externes, chacun des modules comprenant : un dispositif de raccordement électrique vers un bus de données, notamment un fil de raccordement vers l'appareil externe ; un organe d'acquisition de signaux issus du bus de données, éventuellement couplé à un organe de pilotage dudit bus de données, par exemple un relai basse tension à contacts de signalisation ou des moyens de détection d'informations relatives aux fils, notamment sous forme de carte de circuit imprimé ; et un dispositif de communication recevant les informations issues de l'organe d'acquisition, et éventuellement apte à activer l'organe de pilotage en fonction du signal reçu, lui aussi par exemple sous forme de carte de circuit imprimé. Les modules sont logés dans un boîtier du groupe de contrôle et/ou commande, ledit boîtier comprenant un connecteur apte à acheminer les signaux de contrôle et/ou commande entre les dispositifs de communication et une unité centrale. In particular, the invention relates to a group of DI modules, in particular able to receive information relating to external devices, each of the modules comprising: an electrical connection device to a data bus, in particular a connection wire to the external device; a signal acquisition member from the data bus, possibly coupled to a control member of said data bus, for example a low-voltage relay with signaling contacts or means for detecting information relating to the wires, in particular in the form of printed circuit board; and a communication device receiving the information from the acquisition member, and possibly able to activate the control member according to the received signal, also for example in the form of a printed circuit board. The modules are housed in a housing of the control group and / or control, said housing comprising a connector adapted to route the control and / or control signals between the communication devices and a central unit.
L'invention concerne un appareillage électronique intelligent qui comprend, outre le groupe électronique de modules précédent, une embase munie d'un logement apte à recevoir le boîtier des modules, de connecteurs aptes à se raccorder à chacun des dispositifs de raccordement lorsque le groupe électronique est reçu dans l'embase et reliés à une borne de jonction vers les fils de raccordement des appareils externes. L'invention se rapporte enfin à un équipement comprenant au moins un appareillage électronique intelligent et une unité centrale apte à échanger des informations avec les dispositifs de communication du ou des groupes électroniques.

Other advantages and features will emerge more clearly from the following description of particular embodiments of the invention, given by way of illustration and in no way limitative, shown in the accompanying figures.

La figure 2 montre un appareillage de contrôle/commande selon un mode de réalisation de l'invention. Figure 2 shows a control / control apparatus according to one embodiment of the invention.

Dans un mode de réalisation de l'invention illustré en figure 2, un IED 30 comprend plusieurs modules 32, identiques ou non, qui sont logés dans un boîtier commun 34. Chaque module 32 comprend un organe d'acquisition de signalisation externe 36, éventuellement couplé à un organe de pilotage 38, émergeant du boîtier 34 par des moyens de raccordement 40, par exemple un contact mâle/femelle glissant. Les organes 36 peuvent être montés sur une carte de circuit imprimé. Les moyens de raccordement 40 sont connectés indirectement aux équipements 10 contrôlés par l'IED 30 lorsque le module 32 est enfiché dans un support adapté. En particulier, l'IED 30 comprend une embase 42 munie d'un logement 44 dans lequel peut être inséré le boîtier 34. L'embase 42 est fixée dans l'armoire basse tension, et elle comprend des bornes de jonction 46 permettant de la relier aux équipements basse tension 10 environnants notamment par des fils de cuivre isolés 48 ; les bornes 46 peuvent par exemple être des connexions vissées. In one embodiment of the invention illustrated in FIG. 2, an IED 30 comprises several modules 32, identical or not, which are housed in a common housing 34. Each module 32 comprises an external signaling acquisition member 36, optionally coupled to a control member 38, emerging from the housing 34 by connecting means 40, for example a sliding male / female contact. The members 36 may be mounted on a printed circuit board. The connection means 40 are indirectly connected to the equipment 10 controlled by the IED 30 when the module 32 is plugged into a suitable support. In particular, the IED 30 comprises a base 42 provided with a housing 44 in which the housing 34 can be inserted. The base 42 is fixed in the low-voltage cabinet, and it comprises junction terminals 46 enabling the to connect to surrounding low voltage equipment 10 including insulated copper son 48; the terminals 46 may for example be screwed connections.
Les informations de signalisation issues des fils 48, parfois aussi appelés bus de données bien que l'invention concerne principalement des informations de type tout ou rien et non numériques, acquises par le module 32 qui leur est raccordé sont transmises à une unité centrale 50 par un dispositif de communication 52 qui est directement intégré au boîtier 34 du groupe électronique de modules 32 ; le dispositif de communication 52 peut être sous forme de carte de circuit imprimé, séparée ou couplée à celle de l'organe d'acquisition de signalisation externe 36. En particulier, la connexion peut être réalisée par tout moyen, notamment via une liaison numérique. Ainsi, l'embase 42 ne contient plus de connecteur de communication, ni vers l'unité centrale 50, ni vers un module 32 ou le boîtier enfichable 34 : les organes d'acquisition de signalisation externe 36 transmettent les informations acquises via une liaison 54 qui est directement reliée au boîtier 34 par un dispositif de communication 52, par exemple via un connecteur 56, même si une liaison sans fil peut être prévue. De fait, par la nouvelle configuration, l'insertion du module 32 dans l'embase 42 s'accompagne du seul raccordement des organes d'acquisition de signalisation externe 36 par un connecteur 40 dit de puissance, par opposition à un connecteur de communication qui ne transite que des signaux très basse tension. The signaling information from the wires 48, sometimes also called data buses, although the invention mainly concerns on-off and non-digital type information, acquired by the module 32 connected thereto, is transmitted to a central unit 50 by a communication device 52 which is directly integrated with the housing 34 of the electronic module group 32; the communication device 52 may be in the form of a printed circuit board, separate or coupled to that of the external signaling acquisition member 36. In particular, the connection can be made by any means, in particular via a digital link. Thus, the base 42 no longer contains a communication connector, neither to the central unit 50 nor to a module 32 or the plug-in box 34: the external signaling acquisition members 36 transmit the information acquired via a link 54 which is directly connected to the housing 34 by a communication device 52, for example via a connector 56, even if a wireless link can be provided. In fact, by the new configuration, the insertion of the module 32 in the base 42 is accompanied by the only connection of the external signaling acquisition members 36 by a power connector 40, as opposed to a communication connector which only transits very low voltage signals.
Du fait de la séparation des fonctions d'alimentation électrique et de communication d'information, il est également possible de séparer physiquement les deux types de connexion, ce qui simplifie le respect des normes et la réalisation des circuits imprimés associés au dispositif de communication et à l'organe d'acquisition. Due to the separation of the power supply and information communication functions, it is also possible to physically separate the two types of connection, which simplifies the respect of the standards and the production of the printed circuits associated with the communication device and to the acquisition organ.
Lorsque le groupe 34 de modules 32 est débroché, les relais d'acquisition de signalisation externe 36 sont toujours opérationnels puisque la communication numérique entre l'unité de commande 50 et le boîtier 34 n'est plus interrompue : il est possible de tester le bon fonctionnement de ce boîtier 34 même lorsqu'il est débroché de son embase 42, ce qui permet par exemple de vérifier le changement d'état des organes d'acquisition de signalisation externe 36 sans aucune interférence sur les équipements reliés aux fils 48, notamment lors des opérations de mise en service ou de maintenance. When the group 34 of modules 32 is disconnected, the external signaling acquisition relays 36 are still operational since the digital communication between the unit 50 and the housing 34 is not interrupted: it is possible to test the proper operation of this housing 34 even when it is removed from its base 42, which allows for example to check the change of state of organs acquisition of external signaling 36 without any interference on equipment connected to the son 48, especially during commissioning or maintenance operations.
L'équipement est adapté pour la protection, ainsi que pour le contrôle/commande et la télégestion. L'unité centrale 50 peut d'ailleurs comprendre plusieurs ports de communication 58 qui peuvent se raccorder chacun à un appareillage électronique intelligent 30, 30' similaires entre eux ou différents si d'autres fonctions doivent être réalisées. Quel que soit le nombre de ports de communication 58, le raccordement vers un groupe de modules d'entrée DI est réalisé par l'intermédiaire d'un câble 54 de communication de faible section, dont le temps d'installation est bien plus faible que celui des fils de cuivre utilisés pour des modules DI individuels tels qu'illustré en figure 1A. The equipment is suitable for protection, as well as for control / command and remote management. The central unit 50 may moreover comprise a plurality of communication ports 58 which may each connect to an intelligent electronic apparatus 30, 30 'which are similar to one another or different if other functions are to be performed. Regardless of the number of communication ports 58, the connection to a group of input modules DI is made via a communication cable 54 of small section, whose installation time is much lower than that of the copper wires used for individual DI modules as illustrated in Figure 1A.
La solution selon l'invention offre donc l'avantage de permettre un raccordement facilité, à moindre coût, tout en conservant les options de tests individuels des modules DI 32 sans raccordement aux appareillages primaires ou équipements externes 10. A ces gains en temps et coût de raccordement s'ajoute une économie en cuivre, dont l'utilisation est minimisée à des raccordements indispensables. De plus, comme le raccordement électrique d'alimentation 40 et le raccordement de communication 52 de l'appareillage intelligent IED 30 sont localisés dans deux parties distinctes séparables, boîtier et embase, le groupe électronique de contrôle et/ou commande reste opérationnel lors d'une déconnexion de l'IED 30, et les modules de contrôle/commande 32 peuvent par exemple être testés. The solution according to the invention therefore offers the advantage of allowing easy connection, at a lower cost, while retaining the individual test options of the DI 32 modules without connection to the primary equipment or external equipment 10. These gains in time and cost In addition, there is a saving in copper, the use of which is minimized at essential connections. In addition, since the electrical supply connection 40 and the communication connection 52 of the IED 30 intelligent switchgear are located in two separate separable parts, housing and base, the electronic control and / or control unit remains operational when a disconnection of the IED 30, and the control / control modules 32 may for example be tested.
Bien que l'invention ait été décrite en référence à un équipement de contrôle et/ou commande, notamment de protection, avec des relais DI, elle ne s'y limite pas : d'autres éléments peuvent être concernés par l'invention. Notamment, outre des organes d'acquisition de signalisation externe 36, les fils 48 peuvent faire transiter d'autres types d'information, par exemple des signaux analogiques de l'ordre de 4 à 20 mA, et la liaison de communication 52, 54 peut être adaptée pour fournir à l'unité centrale 50 des informations relatives à ces autres types de signaux, par exemple pour former un équipement de télégestion du réseau. En particulier, l'équipement selon l'invention peut être adapté pour gérer à distance des installations de type WAGES (pour « Water, Air, Gas, Electricity and Steam » selon la terminologie anglo-saxonne), c'est-à-dire vérifier des paramètres relatifs à des moteurs industriels dans les applications dans le domaine de l'eau (pompes...), air (climatisation,...), gaz (valves,...), électricité, vapeur, ou des paramètres climatiques et environnementaux pour la gestion de motorisations d'installations de production d'énergie renouvelable. Although the invention has been described with reference to a control equipment and / or control, including protection, with DI relays, it is not limited to: other elements may be concerned by the invention. In particular, in addition to the external signal acquisition means 36, the wires 48 can pass other types of information, for example analog signals of the order of 4 to 20 mA, and the communication link 52, 54 may be adapted to provide the CPU 50 with information relating to these other types of signals, for example to form a network remote management equipment. In particular, the equipment according to the invention can be adapted to remotely manage installations of WAGES type (for "Water, Air, Gas, Electricity and Steam"), that is to say check parameters relating to industrial engines in applications in the field of water (pumps ...), air (air conditioning, ...), gas (valves, ...), electricity, steam, or parameters climatic and environmental aspects for the management of engines for renewable energy production facilities.
