Abstract
Description
La présente invention concerne un dispositif décaleur-adaptateur de tension électrique destiné à compenser les chutes de tension dues à l'impédance du réseau de distribution électrique généralement en zone rurale et en bout de ligne et répartir la tension régulée au travers d'un délesteur-décaleur.The present invention relates to an electrical voltage shifter-adapter device intended to compensate for voltage drops due to the impedance of the electrical distribution network generally in rural areas and at the end of the line, and to distribute the regulated voltage through a load shedder. shifter.
On connaft différents dispositifs pour pallier lesditesj chutes de tension notamment l'utilisation d'un ensemble redresseur-batterieonduleur. Ce mode de dispositif présente certains inconvénients, d'une part au niveau des batteries qui sont des éléments chers et polluants, et dont le nombre en fonction de l'utilisation est important, tel que par exemple pour une installation de 6 kVA, le dimensionnement normal est de 60 kWh, ce qui correspond à soixante batteries de 1 kWh ; d'autre part, la vie des batteries est limitée dans le temps ce qui nécessite leur changement régulier.Various devices are known for overcoming said voltage drops, in particular the use of a rectifier-battery-inverter assembly. This mode of device has certain drawbacks, on the one hand with batteries which are expensive and polluting elements, and the number of which depends on the use is large, such as for example for a 6 kVA installation, the dimensioning normal is 60 kWh, which corresponds to sixty 1 kWh batteries; on the other hand, the life of the batteries is limited in time which requires their regular change.
On connait aussi l'usage de délesteurs-décaleurs de charge qui permettent de gérer au mieux l'alimentation d'appareils électriques à certaines périodes de la journée et de limiter la consommation totale d'une installation ; ce mode de dispositif est contraignant pour l'usager, dans la mesure où ces actions peuvent ne pas être transparentes pour lui.We also know the use of load shedgers-shifters that allow to better manage the power supply of electrical devices at certain times of the day and limit the total consumption of an installation; this mode of device is binding on the user, insofar as these actions may not be transparent to him.
On connalt aussi des appareils de régulation de tension utilisant le principe des transformateurs variables, tels que ceux décrits dans les brevets 2 634 079 et 2 637 426, ces types d'appareil permettant de rattrapper des chutes de tension de l'ordre de 20%, au-delà le fonctionnement des appareils est trés aléatoire. De plus l'autoconsommation de ces appareils, constamment branchés sur le réseau, est importante.Voltage regulating devices using the principle of variable transformers are also known, such as those described in patents 2,634,079 and 2,637,426, these types of device making it possible to compensate for voltage drops of the order of 20%. , beyond the operation of the devices is very random. In addition, the self-consumption of these devices, constantly connected to the network, is important.
L'invention a pour but de pallier aux inconvénients précédemment exposés.The invention aims to overcome the drawbacks described above.
L'invention a pour objet un dispositif décaleur-adaptateur de tension comportant en prolongement de la ligne d'alimentation électrique un transformateur à rapport variable prolongé par un délesteur-décaleur aménagé de plusieurs sorties dotées chacune d'un contacteur, lesdits contacteurs étant pris en charge par une logique de commande afin qu'en temps réel ils connectent et déconnectent diverses charges à des périodes définies et/ou selon des conditions de tension et de courant consommé particulières.The subject of the invention is a voltage shifter-adapter device comprising, as an extension of the power supply line, a variable ratio transformer extended by a load shedder-shifter fitted with several outputs each provided with a contactor, said contactors being taken into account. load by a control logic so that in real time they connect and disconnect various loads at defined periods and / or according to particular voltage and current consumption conditions.
D'autres caractéristiques et avantages de l'invention ressortiront plus clairement de la description qui va suivre faite en regard du schéma joint donné à titre d'exemple non limitatif.Other characteristics and advantages of the invention will emerge more clearly from the description which follows, given with regard to the attached diagram given by way of nonlimiting example.
Tel que représenté, le dispositif décaleur-adaptateur de tension cornporte, prolongeant la ligne d'alimentation électrique 1, un transformateur à rapport variable 2 afin d'adapter l'impédance de la ligne d'apport à celle d'utilisation, le transformateur 2 est en sortie prolongé par un délesteur-décaleur 3 contenu dans un bottier éloigné et différent, aménagé de plusieurs sorties 4 dotées chacune d'un contacteur 5, lesdits contacteurs 5 étant pris en charge par une logique de commande 6 afin qu'en temps réel ils connectent ou déconnectent diverses charges en des périodes définies au regard de l'usage des appareils et selon des modes limitant au maximum les contraintes pour l'utilisateur. Il va de soi que la tension régulée peut être directement utilisée en continu pour certains appareils grace à la sortie 12.As shown, the voltage shifter-adapter device includes, extending the power supply line 1, a variable ratio transformer 2 in order to adapt the impedance of the supply line to that of use, the transformer 2 is extended by a load shedder-shifter 3 contained in a remote and different shoemaker, fitted with several outputs 4 each provided with a contactor 5, said contactors 5 being supported by a control logic 6 so that in real time they connect or disconnect various loads in defined periods with regard to the use of the devices and according to modes minimizing the constraints for the user. It goes without saying that the regulated voltage can be directly used continuously for certain devices thanks to output 12.
Sans sortir du cadre de l'invention, la logique de commande peut selon la prograrnrnation distribuer en des périodes définies et/ou selon des conditions de tension et de courant consommé particulières une tension non régulée au moyen du relais 7 qui dirige la tension au moyen de la déviation 8 directement vers le délesteur-décaleur 3, ledit relais 7 étant pris en charge par la logique de commande 6. Dans cette configuration, I'autoconsommation de l'ensemble est fortement réduite.Without departing from the scope of the invention, the control logic can, depending on the program, distribute in defined periods and / or according to particular voltage and current consumption conditions an unregulated voltage by means of relay 7 which directs the voltage by means from deflection 8 directly to the load shedder-shifter 3, said relay 7 being taken over by the control logic 6. In this configuration, the self-consumption of the assembly is greatly reduced.
Selon une autre variante, la tension non régulée peut être directement utilisée de manière perrnanente gracie à la déviation 9 et sortie 10 et être aussi dirigée par la déviation 11 vers le délesteur-décaleur 3 afin d'être pris en charge par la logique de commande 6. According to another variant, the unregulated voltage can be directly used permanently thanks to the deviation 9 and output 10 and also be directed by the deviation 11 towards the load shedder-shifter 3 in order to be taken over by the control logic 6.
