Description

La présente invention concerne un dispositif de commande du fonctionnement d'un contacteur.The present invention relates to a device for controlling the operation of a contactor.

Plus particulièrement, le dispositif selon l'invention se rapporte à la commande du fonctionnement d'un contacteur du type comportant une bobine d'appel et une bobine de maintien en position active d'un équipage mobile.More particularly, the device according to the invention relates to the control of the operation of a contactor of the type comprising a take-up coil and a coil for maintaining in active position a moving element.

Dans l'état de la technique, la bobine d'appel et la bobine de maintien sont en général connectées en série l'une avec l'autre et un interrupteur est connecté en parallèle aux bornes de la bobine de maintien pour provoquer la mise en court-circuit de cette bobine lors d'une première phase de fonctionnement du contacteur après son déclenchement.In the state of the art, the take-up coil and the holding coil are generally connected in series with each other and a switch is connected in parallel to the terminals of the holding coil to cause the activation. short-circuit of this coil during a first operating phase of the contactor after it has tripped.

En effet, lors de cette première phase de fonctionnement, seule la bobine d'appel doit être alimentée pour provoquer un déplacement rapide de l'équipage mobile.In fact, during this first phase of operation, only the call coil must be supplied to cause rapid movement of the moving assembly.

Une fois que cet équipage mobile est en position active, on provoque l'ouverture de l'interrupteur de mise en court-circuit de la bobine de maintien de manière que celle-ci soit connectée en série avec la bobine d'appel afin de réduire le courant circulant dans ces bobines.Once this moving element is in the active position, the holding coil short-circuiting switch is opened so that it is connected in series with the take-up coil in order to reduce the current flowing in these coils.

Cependant, cette structure présente un certain nombre d'inconvénients notamment au niveau de l'obligation de prévoir cet interrupteur de mise en court-cirucit de l'une des bobines et du dimensionnement de celles-ci pour obtenir les différentes caractéristiques de fonctionnement notamment de temps de déplacement de l'équipage mobile vers sa position active et vers sa position escamotée et d'échauffement limité des bobines.However, this structure has a certain number of drawbacks, in particular in terms of the obligation to provide this short-circuiting switch for one of the coils and the dimensioning of these to obtain the different operating characteristics, in particular of travel time of the moving element towards its active position and towards its retracted position and limited heating of the coils.

Dans l'état de la technique le document FR-A-2.611.981 décrit et représente un relais de démarrage de véhicule à moteur qui comporte plusieurs bobines en parallèles qui sont alimentées successivement afin de limiter la force d'appel. Dans un premier temps, une seule bobine est commandée, puis deux, puis trois bobines, seule la première bobine restant alimentée pour le maintien du relais dans le cas d'une chute de la tension d'alimentation. Ce document enseigne donc qu'il est connu de commander séparément plusieurs bobines en parallèle, en particulier simultanément pendant la phase d'appel, mais ce document ne traite pas le problème du maintien du relais dans le cas d'une chute de la tension d'alimentation.In the state of the art the document FR-A-2,611,981 describes and represents a motor vehicle starting relay which comprises several coils in parallel which are supplied successively in order to limit the appeal force. Initially, a single coil is controlled, then two, then three coils, only the first coil remaining supplied for maintaining the relay in the event of a drop in the supply voltage. This document therefore teaches that it is known to control several coils separately in parallel, in particular simultaneously during the call phase, but this document does not deal with the problem of maintaining the relay in the event of a drop in the voltage d 'food.

Le document EP-A-0164.014 décrit et représente un relais de signalisation qui peut fonctionner sous deux tensions différentes, c'est-à-dire une tension haute qui peut varier entre 20 et 26,5 Volts et une tension basse qui peut varier entre 10,5 et 13,5 Volts. Une résistance, pouvant être shuntée par un interrupteur, est branchée en série avec le relais. Le document n'indique pas que le relais puisse comporter plusieurs bobines de commande. Si la tension est basse, ce qui est détecté par un comparateur, l'interrupteur est fermé et le relais est alimenté directement. Si la tension est haute, la fermeture de l'interrupteur est commandée par une bascule monostable et la durée de l'impulsion de la bascule transmise par un circuit OU est telle que le fonctionnement du relais est assuré. Ensuite, le relais est alimenté en série avec la résistance dont la valeur est choisie de manière à maintenir la tension minimale de maintien sur le relais. Ce document ne traite donc en aucune manière du problème de maintien en cas de chute de la tension d'alimentation.The document EP-A-0164.014 describes and represents a signaling relay which can operate under two different voltages, that is to say a high voltage which can vary between 20 and 26.5 volts and a low voltage which can vary between 10.5 and 13.5 Volts. A resistor, which can be shunted by a switch, is connected in series with the relay. The document does not indicate that the relay can have multiple control coils. If the voltage is low, which is detected by a comparator, the switch is closed and the relay is supplied directly. If the voltage is high, the closing of the switch is controlled by a monostable flip-flop and the duration of the flip-flop pulse transmitted by an OR circuit is such that the operation of the relay is ensured. Then, the relay is supplied in series with the resistor whose value is chosen so as to maintain the minimum holding voltage on the relay. This document therefore does not in any way deal with the problem of maintenance in the event of a drop in the supply voltage.

Le document GB-A-2.156.156 enseigne simplement le fait de commander un relais de disjoncteur par des bobines en parallèle dont une peut être commandée séparément de l'autre.The document GB-A-2,156,156 teaches simply the fact of controlling a circuit breaker relay by coils in parallel, one of which can be controlled separately from the other.

Aucun de ces documents ne décrit, ni même ne suggère, le problème de maintien du relais en cas de chute de tension.None of these documents describes, or even suggests, the problem of maintaining the relay in the event of a voltage drop.

Ce problème est particulièrement important pour les relais de démarreur car le courant absorbé par le démarreur est très élevé, ce qui entraîne une chute de tension importante.This problem is particularly important for starter relays because the current absorbed by the starter is very high, which causes a significant voltage drop.

Le but de l'invention est donc de résoudre ces problèmes.The object of the invention is therefore to solve these problems.

A cet effet, l'invention a pour objet un dispositif de commande du fonctionnement d'un contacteur comportant une bobine d'appel et une bobine de maintien en position active d'un équipage mobile, dont l'alimentation est pilotée par des moyens de commande, caractérisé en ce que les moyens de commande comportent des moyens séparés de commande de l'alimentation des bobines, recevant en entrée une information de tension d'alimentation du contacteur, pour :

  • alimenter simultanément les deux bobines lors du déclenchement du fonctionnement du contacteur;
  • couper l'alimentation de la bobine d'appel au bout d'un temps déterminé après le déclenchement du fonctionnement du contacteur; et
  • alimenter à nouveau la bobine d'appel en cas de chute déterminée de la tension d'alimentation du contacteur lors du fonctionnement de celui-ci.
To this end, the subject of the invention is a device for controlling the operation of a contactor comprising a call coil and a coil for maintaining the active position of a mobile assembly, the supply of which is controlled by means of control, characterized in that the control means comprise separate means for controlling the supply of the coils, receiving as input a supply voltage information from the contactor, for:
  • simultaneously supply the two coils when the contactor operation is triggered;
  • cut the supply to the call coil after a determined time after the contactor has been triggered; and
  • supply the call coil again in the event of a determined drop in the supply voltage of the contactor during its operation.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée qui va suivre pour la compréhension de laquelle on se reportera aux dessins annexés dans lesquels :

  • la figure 1 représente un schéma synoptique d'un dispositif de commande du fonctionnement d'un contacteur de l'état de la technique;
  • la figure 2 représente un schéma synoptique d'un dispositif de commande du fonctionnement d'un contacteur selon l'invention; et
  • la figure 3 illustre le fonctionnement du dispositif de commande selon l'invention.
Other characteristics and advantages of the invention will appear on reading the detailed description which follows for the understanding of which reference will be made to the appended drawings in which:
  • FIG. 1 represents a block diagram of a device for controlling the operation of a contactor of the prior art;
  • FIG. 2 represents a block diagram of a device for controlling the operation of a contactor according to the invention; and
  • Figure 3 illustrates the operation of the control device according to the invention.

Ainsi qu'on peut le voir sur la figure 1, il existe dans l'état de la technique, des contacteurs qui comportent deux bobines, l'une dite bobine d'appel désignée par la référence générale 1 sur cette figure et l'autre dite bobine de maintien désignée par la référence générale 2.As can be seen in Figure 1, there are in the state of the art, contactors which have two coils, one called the call coil designated by the general reference 1 in this figure and the other said retaining coil designated by the general reference 2.

Un interrupteur de mise en court-circuit de la bobine de maintien, désigné par la référence générale 3, est prévu en parallèle sur cette bobine.A holding coil short-circuiting switch, designated by the general reference 3, is provided in parallel on this coil.

On notera que ces bobines d'appel et de maintien sont connectées en série entre une borne d'alimentation et le collecteur d'un transistor d'alimentation désigné par la référence générale 4 sur cette figure, ce collecteur étant relié à une borne positive de l'alimentation à travers une résistance 5. L'émetteur de ce transistor est relié à la masse et la base de celui-ci reçoit un signal de pilotage de moyens de commande désignés par la référence générale 6, recevant sur des entrées, des informations logiques de commande désignées par la référence 7.It will be noted that these call and holding coils are connected in series between a supply terminal and the collector of a supply transistor designated by the general reference 4 in this figure, this collector being connected to a positive terminal of the power supply through a resistor 5. The emitter of this transistor is connected to ground and its base receives a control signal from control means designated by the general reference 6, receiving information on inputs control units designated by reference 7.

Les moyens de commande présentent une structure classique à base par exemple d'un contrôleur de décodage des informations.The control means have a conventional structure based for example on an information decoding controller.

On notera qu'un organe de protection est connecté en parallèle sur les bobines d'appel et de maintien et est désigné par la référence générale 8.It will be noted that a protection member is connected in parallel on the call and holding coils and is designated by the general reference 8.

Le fonctionnement de ce dispositif est le suivant.The operation of this device is as follows.

Dans l'état initial de ce dispositif, l'interrupteur 3 est fermé de sorte que la bobine de maintien 2 est en court-circuit.In the initial state of this device, the switch 3 is closed so that the holding coil 2 is short-circuited.

Les moyens de commande 6, sous la commande des informations 7, provoquent l'alimentation de la bobine d'appel à travers le transistor 4.The control means 6, under the control of the information 7, cause the supply of the call coil through the transistor 4.

L'équipage mobile du contacteur est alors attiré vers sa position active.The moving part of the contactor is then drawn to its active position.

Au bout d'un temps déterminé, supérieur au temps nécessaire à l'équipage mobile pour arriver en position active, l'interrupteur de mise en court-circuit 3 est ouvert de sorte que la bobine de maintien 2 est connectée en série avec la bobine d'appel 1 afin de réduire le courant circulant dans ces bobines.After a determined time, greater than the time necessary for the moving element to reach the active position, the short-circuiting switch 3 is open so that the holding coil 2 is connected in series with the coil call 1 to reduce the current flowing in these coils.

Dans un exemple de réalisation, le contacteur est alimenté par une tension continue, VAlim, dont la valeur nominale est de 28 Volts et qui peut varier dans de grandes proportions, par exemple de 10 à 32 V.In an exemplary embodiment, the contactor is supplied by a direct voltage, VAlim, whose nominal value is 28 Volts and which can vary in large proportions, for example from 10 to 32 V.

La bobine d'appel est alimentée par un créneau de courant de 40 mS pour une tension de 28 V et une température de 20°C. La précision admissible pour cette durée du créneau est fonction de la valeur de la tension (10 à 32 V.) et de la température, qui peut varier par exemple entre -55°C et +85°C.The call coil is supplied by a 40 mS current slot with a voltage of 28 V and a temperature of 20 ° C. The admissible accuracy for this time period depends on the value of the voltage (10 to 32 V.) and the temperature, which can vary for example between -55 ° C and + 85 ° C.

Le courant d'appel est égal à 1 A pour la tension nominale de 28 V et une température de 20°C alors que le courant de maintien dans les même conditions n'est que de 250 mA.The inrush current is equal to 1 A for the nominal voltage of 28 V and a temperature of 20 ° C while the holding current under the same conditions is only 250 mA.

La tension de seuil inférieur en dessous de laquelle la bobine d'appel est réactivée est fixée entre 12 V et 12,5 V et la tension de seuil supérieur au dessus de laquelle la bobine d'appel est désactivée lorsqu'elle avait été réactivée est fixée entre 14 V et 14,5 V.The lower threshold voltage below which the call coil is reactivated is fixed between 12 V and 12.5 V and the upper threshold voltage above which the call coil is deactivated when it was reactivated is fixed between 14 V and 14.5 V.

La tension de commande du contacteur, VCde, doit être au moins égale à 3 V pour une tension d'alimentation, VAlim, qui doit être supérieure à 18 V. Ceci est obtenu au moyen d'une porte logique ET qui reçoit en entrée deux signaux représentatifs de la valeur des tensions de commande et d'alimentation et commande la délivrance du créneau d'alimentation de la bobine d'appel indiqué ci-dessus. Si la tension de commande tombe en dessous de cette valeur de 3 V, le dispositif de commande économiseur selon l'invention commande l'ouverture du contacteur.The contactor control voltage, VCde, must be at least 3 V for a supply voltage, VAlim, which must be greater than 18 V. This is obtained by means of an AND logic gate which receives two inputs signals representative of the value of the control and supply voltages and controls the delivery of the supply niche of the call coil indicated above. If the control voltage falls below this value of 3 V, the economizer control device according to the invention controls the opening of the contactor.

Le fonctionnement du contacteur est résumé sur la figure 3 dans le cas d'une baisse de la tension d'alimentation puis dans le cas d'une réaugmentation de cette tension consécutive à une baisse. Par ailleurs, le tableau qui suit fournit les différentes valeurs de réglage en fonction de la température de fonctionnement.

The operation of the contactor is summarized in FIG. 3 in the case of a drop in the supply voltage and then in the case of a increase in this voltage following a drop. In addition, the following table provides the different setting values depending on the operating temperature.
Figure imgb0001

Ainsi qu'on l'a mentionné précédemment, cette structure présente un certain nombre d'inconvénients du fait de l'utilisation d'un interrupteur de mise en court-circuit de la bobine de maintien et de la nécessité de surdimensionner les bobines et en particulier la bobine d'appel afin de provoquer un déplacement rapide de l'équipage mobile vers sa position active dans la mesure où lors de cette phase de fonctionnement, la bobine de maintien ne participe pas à ce déplacement.As mentioned previously, this structure has a number of drawbacks due to the use of a short-circuiting switch for the holding coil and the need to oversize the coils and in particular the call coil in order to cause a rapid displacement of the moving assembly towards its active position insofar as during this operating phase, the retaining coil does not participate in this displacement.

Par ailleurs, cette structure présente également des problèmes d'échauffement des bobines et une faible capacité d'adaptation à des variations importantes de la tension d'alimentation du contacteur.Furthermore, this structure also presents problems of heating of the coils and a low capacity of adaptation to large variations in the supply voltage of the contactor.

Le dispositif de commande selon l'invention permet de résoudre ces problèmes.The control device according to the invention overcomes these problems.

Un schéma synoptique de ce dispositif est représenté sur la figure 2, dans laquelle des éléments analogues à ceux représentés sur la figure 1 sont désignés par les mêmes numéros de référence.A block diagram of this device is shown in Figure 2, in which elements similar to those shown in Figure 1 are designated by the same reference numbers.

C'est ainsi que l'on reconnaît sur cette figure 2, la bobine d'appel 1, la bobine de maintien 2, les moyens de commande 6 et les informations de commande 7.This is how we recognize in this FIG. 2, the call coil 1, the holding coil 2, the control means 6 and the control information 7.

Contrairement au dispositif classique représenté sur la figure 1, dans le dispositif de commande selon l'invention, les moyens de commande de l'alimentation des bobines comprennent des moyens séparés de commande de l'alimentation de celles-ci.Unlike the conventional device shown in FIG. 1, in the control device according to the invention, the means for controlling the supply of the coils comprise separate means for controlling the supply of the latter.

En effet, dans le dispositif représenté sur cette figure 2, l'une des bornes de chaque bobine 1, 2 est connectée à une borne d'alimentation, tandis que l'autre borne de chacune de celles-ci est reliée au collecteur d'un transistor respectivement 9,10, ces collecteurs étant reliés à une borne d'alimentation à travers des résistances 11 et 12.Indeed, in the device shown in this figure 2, one of the terminals of each coil 1, 2 is connected to a supply terminal, while the other terminal of each of these is connected to the collector a transistor 9,10 respectively, these collectors being connected to a supply terminal through resistors 11 and 12.

Les émetteurs de ces transistors sont reliés à la masse et les bases de ceux-ci sont reliées à des sorties de pilotage des moyens de commande 6 en fonction des informations logiques de commande 7.The emitters of these transistors are connected to ground and the bases of these are connected to pilot outputs of the control means 6 as a function of the logic control information 7.

Des organes de protection 13 et 14 sont connectés en parallèle aux bornes des bobines.Protection members 13 and 14 are connected in parallel to the terminals of the coils.

Par ailleurs, les moyens de commande reçoivent également en entrée une information de tension d'alimentation du contacteur, comme cela sera décrit plus en détail par la suite.Furthermore, the control means also receive, as input, supply voltage information from the contactor, as will be described in more detail below.

On conçoit alors que la commande séparée des bobines permet d'améliorer les caractéristiques de fonctionnement du contacteur.It can therefore be seen that the separate control of the coils makes it possible to improve the operating characteristics of the contactor.

En effet, les moyens de commande séparés de l'alimentation des bobines peuvent être adaptés pour alimenter simultanément les bobines d'appel et de maintien lors du déclenchement du fonctionnement du contacteur, pour accélérer le déplacement de l'équipage mobile vers sa position active.In fact, the separate control means for supplying the coils can be adapted to simultaneously supply the call and holding coils when the operation of the contactor is triggered, in order to accelerate the movement of the moving element to its active position.

L'alimentation de la bobine d'appel 1 est ensuite coupée au bout d'un temps déterminé supérieur au temps de déplacement de l'équipage mobile vers sa position active par contrôle du fonctionnement du transistor 9.The supply to the call coil 1 is then cut off after a determined time greater than the time for the moving equipment to move to its active position by checking the operation of the transistor 9.

Cependant, cette bobine d'appel 1 peut à nouveau être alimentée en cas de chute de tension déterminée de la tension d'alimentation du contacteur, chute de tension qui risquerait de provoquer le retour de l'équipage mobile vers sa position escamotée.However, this call coil 1 can again be supplied in the event of a determined voltage drop in the supply voltage of the contactor, voltage drop which would risk causing the moving assembly to return to its retracted position.

Les moyens de commande 6 contrôlent en permanence la tension d'alimentation du contacteur et déclenchent l'alimentation de la bobine d'appel lorsque cette tension chute au-dessous d'un seuil déterminé, ce qui se produit notamment en cas de forte charge du reste du circuit.The control means 6 permanently monitor the supply voltage of the contactor and trigger the supply of the call coil when this voltage drops below a determined threshold, which occurs in particular in the event of a high load of the rest of the circuit.

On conçoit alors que l'alimentation des bobines est commandée en fonction de l'évolution de la charge dans le reste du circuit pour permettre un meilleur fonctionnement du contacteur.It is therefore understood that the supply of the coils is controlled as a function of the evolution of the load in the rest of the circuit to allow better operation of the contactor.

L'alimentation de la bobine d'appel en cas de chute importante de la tension d'alimentation du contacteur permet de réduire de façon notable le courant dans la bobine de maintien et par conséquent le volume de cuivre des bobines de même que le volume de fer du circuit magnétique de ce contacteur.The supply of the call coil in the event of a significant drop in the supply voltage of the contactor makes it possible to significantly reduce the current in the holding coil and consequently the volume of copper in the coils as well as the volume of iron of the magnetic circuit of this contactor.

La réduction des courants d'appel et de maintien se traduit également par une réduction de l'échauffement des bobines.The reduction in inrush and holding currents also results in a reduction in the heating of the coils.

Par ailleurs, cette structure permet également d'assurer une plus grande vitesse de déplacement de l'équipage mobile d'une part de sa position escamotée vers sa position active et d'autre part, de sa position active vers sa position escamotée, du fait de l'énergie plus faible emmagasinée dans les bobines.Furthermore, this structure also makes it possible to ensure a greater speed of movement of the mobile assembly on the one hand from its retracted position to its active position and on the other hand, from its active position to its retracted position, because lower energy stored in the coils.

Enfin, il est également à noter que l'interrupteur de mise en court-circuit de la bobine de maintien est supprimé, cet interrupteur étant relativement difficile à régler.Finally, it should also be noted that the switch for short-circuiting the holding coil is eliminated, this switch being relatively difficult to adjust.
