Definitions
- the present invention relates to the field of electrical switchgear, in particular the disconnector or earthing switch type, preferably high voltage.
- the invention relates to an electrically conductive moving assembly of the apparatus, intended to be set in motion by a drive device and being conventionally equipped with a permanent contact and an electric arc contact.
- the electrically conductive assembly of an electrical switchgear of the disconnector or earthing switch type is moved at constant translation speed during each opening operation and during each operation. closure.
- the conductor assembly which generally takes the form of a cylinder equipped with a permanent contact and an electric arc contact, undergoes mechanical and electrical stresses that gradually lead to its degradation. This phenomenon is also observed on the other permanent contact and on the other arcing contact of the apparatus.
- the document FR 2 547 107 proposes an electrical apparatus with a fixed arc contact coupled to a spring, which makes it possible to accelerate the spacing speed of the two arcing contacts at the time of their separation. Nevertheless, the fixed arcing contact can no longer really be regarded as fixed, since it is slidably mounted on the fixed frame of the apparatus.
- conventional designs of switchgear usually do not monitor the area of the fixed contact, so that the detection of a possible anomaly on the spring is not possible. This seems unacceptable, as a failure of the undetected spring would cause a dangerous malfunction of the switchgear.
- the invention therefore aims to at least partially overcome the disadvantages mentioned above, relating to the achievements of the prior art.
- the subject of the invention is an electrical switchgear, in particular a disconnector or an earthing switch, comprising an electrically conductive moving assembly comprising an electrically conductive main body incorporating a permanent contact and an arc contact. electric.
- said movable electrically conductive assembly also comprises a secondary body slidably mounted relative to said main body in a direction of movement of said electrically conductive assembly, said secondary body being intended to be connected to an attachment point of a drive device of said movable electrically conductive assembly, the latter further comprising resilient return means interposed between said main body and said secondary body, and said apparatus being designed so that during an opening operation, said elastic return means can first store energy by displacement of the secondary body relative to the main body, then release the stored energy to cause an acceleration of said main body.
- the invention is first of all remarkable in that it makes it possible to vary the speed of the main body of the moving assembly, during the same opening operation, by means of the acceleration caused. by the release of energy from the elastic return means. Consequently, this controlled variation can be determined in such a way as to best limit the mechanical and electrical wear of the electrically conductive assembly.
- the release of energy is preferentially initiated after the separation of the permanent contacts, and during the separation of the arcing contacts, that is to say initiated at the precise moment of the separation of the contacts. arcs or before that moment, and completed after they are separated.
- the speed of the moving arc contact embossed on the electrically conductive assembly is even higher during this critical phase of the opening operation, which limits the damage due to electrical stresses.
- the invention is also advantageous in that it allows a variation in the speed of the main body of the moving assembly, while moving said attachment point constant speed of translation. Therefore, the driving device of this conductive assembly can advantageously incorporate a motor driven at a speed constant, even if a variable speed could be implemented, without departing from the scope of the invention.
- the acceleration spring is not arranged on the side of the fixed elements, but on the assembly comprising the movable electrodes.
- the proposed solution reduces the overall size of the equipment compared to those encountered in the prior art.
- the modification made to the fixed contact to make it slightly mobile causes a significant increase in the dimensioning, especially for purposes of translational guidance of this contact.
- the impact on the dimensioning is much smaller because this assembly already has a large bulk, notably a long length for ensure its guidance in translation. This large space can therefore advantageously be used to integrate said secondary body and the elastic return means, without much impact on the sizing overall, or even with no impact on this dimensioning.
- the apparatus comprises stop means allowing, during an opening operation, to block the translational movement of said main body relative to a fixed body of the apparatus, said secondary body being equipped with means unlocking means adapted to release said abutment means after said secondary body has been moved relative to the main body by a predetermined distance.
- said elastic return means comprise at least one compression or traction spring.
- said stop means are arranged on a fixed body of the apparatus and on the main body of the movable electrically conductive assembly.
- the electrical equipment could also have resilient means of return function similar to that described above, to accelerate the contacts during a specific phase of the closing operation. This could for example be done by replacing the compression spring with a tension spring. If a solution with several springs is therefore envisaged, however, it is possible to use the same spring to ensure the required acceleration during opening and closing, respectively after compression and traction, or vice versa.
- the electrical equipment also comprises a drive device of said mobile assembly, this device comprising a rotary input shaft and an output member having said attachment point to said electrically conductive assembly, said attachment point being movable in translation in the direction of movement of said electrically conductive assembly.
- this driving device comprises a mechanical system for transmitting motion between said point of attachment and said rotary input shaft, this mechanical system being designed to obtain a variable speed of the point of attachment when a constant angular speed rotation of said rotary input shaft, during an opening operation and / or during a closing operation of the electrical equipment.
- the speed of the electrically conductive assembly can be slow, until the separation of the permanent contacts in order to limit the mechanical wear thereof then rise to limit the electrical wear of the arcing contacts.
- the variation of the speed of the output member can be adapted to limit at best the harmful effects of the induced, capacitive, bar transfer and closure currents. on short circuit.
- the variation of the translational speed of the output member is obtained with a constant angular velocity of the input shaft, easily applicable with the aid of an electric motor. classic. Nevertheless, a variable angular velocity could be applied to the input shaft.
- the shaft can be connected directly or indirectly to the electric drive motor, or even be the output shaft of the engine.
- the input rotary shaft can be manually operated by a crank, as is known to those skilled in the art. During this actuation, the operator will advantageously benefit from the reduction effect and / or overdrive speed mechanically conferred by said specific transmission system.
- the mechanical transmission system therefore preferably takes the form of a positive-acting link between the rotary input shaft and the output member comprising the attachment point.
- positive action it is meant that there exists a bidirectional link between these two last elements, implying in particular that at any position of the point of attachment corresponds an angular position of the tree. of entry, and vice versa, and in all points between the two extreme positions.
- said mechanical system comprises at least two elements each provided with a groove and a movable pin member movable in the groove of the other of the two elements.
- Each element thus forms a kind of cam cooperating with its associated member which performs a similar function to that of a cam follower.
- This technology is particularly reliable and easily achievable.
- the number, arrangement and shape of the elements, grooves and peg members can be modulated according to the desired speed variations.
- the mechanical transmission system is designed so that the driving of one of the two elements by the other of the elements is carried out by pressing one of the peg members into the bottom of its associated groove, and by simultaneously moving the other peg member into its associated groove.
- the driving element of the transmission is the support of the peg member in the bottom of its associated groove, the simultaneous movement of the other peg member in its associated groove serving more to maintain a desired orientation of the element or elements involved.
- the mechanical transmission system is designed so that during an opening operation and / or during a closing operation of the electrical equipment, each organ pin forming passes at least once of its configuration in abutment against the bottom of its groove associated with its configuration moving in its associated groove, or vice versa.
- This configuration change is naturally conducive to obtaining a linear speed change of the output member.
- these changes are made simultaneously, that is to say that the moment when one of the two pawn members leaves the bottom of its associated groove corresponds to the moment when the other member enters into position. contact with the bottom of its associated groove.
- the mechanical transmission system is designed so that the two pawn members respectively describe, during an opening operation and / or during a closing operation of the electrical equipment, two concentric trajectories respectively. in an arc centered on an axis of said rotary input shaft.
- this is naturally conducive to obtaining a linear speed change of the output member, since being located at different distances from the axis of the input shaft, the two pins present necessarily different linear speeds during the rotation of this input shaft.
- one of the two elements of the mechanical transmission system is integral in rotation with said rotary input shaft, and the other of the two elements carries a connecting rod on which is said attachment point.
- similar intermediate elements could be arranged between these two elements, as has been mentioned above, without departing from the scope of the invention.
- the apparatus comprises an electric motor driving the rotary input shaft of the drive device.
- this disconnector may be an earthing switch, preferably high voltage.
- the disconnector 1 comprises a cutoff chamber 2 shown only partially, enclosed in an enclosure containing an insulating gas such as SF6 gas or any other gaseous mixture deemed appropriate.
- the chamber 2 encloses a stationary permanent contact 4a and a fixed electric arc contact 5a located radially inwardly relative to the permanent contact 4a.
- it contains an electrically conductive moving assembly 6, electrically connected to a fixed body 8 in which it is movable in translation, in a direction of displacement represented by the arrow 11.
- This assembly 6 has an end equipped with a permanent contact mobile 4b, and a movable arcing contact 5b, intended to cooperate with the contacts 4a, 5a mentioned above.
- the assembly 6 generally takes the form of a sliding cylinder, like the piston of a jack, in a cylindrical housing 10 of the body 8. It comprises a main body 9 electrically conductive, forming an outer body, and integrating the permanent contact 4b and the electric arc contact 5b. Inside this main body 9 is formed a through bore 12 oriented in the direction 11, and slidably housing a secondary body 14. Thus, the secondary body 14 is slidably mounted relative to the main body 9 in the direction of displacement 11.
- the electrically conductive assembly 6 comprises elastic return means, such as a compression spring 16, forcing the secondary body 14 to move towards a first end position relative to the main body, corresponding at the position in which it is located closer to the fixed permanent contact 4a.
- This first position, towards which the spring 16 tends to push the secondary body 14 also corresponds to a position in which the body 14 is located in the bottom 17 of the opening bore 12.
- the spring 16 disposed around the secondary body 14 is supported at one of its ends on a flange 18 of the body, and is supported at the other end thereof on a ring 20 fixedly mounted in the bore opening 12 of the body 9.
- this body secondary 14 is connected to an attachment point 22 of a driving device 30, a preferred embodiment of which will now be described. Nevertheless, any other conventional embodiment could be retained to drive the point of attachment 22, without departing from the scope of the invention.
- the device 30 comprises a rotary input shaft 32, substantially orthogonal to the sliding direction 11 of the moving assembly 6. As shown schematically on the figure 2 , the input rotary shaft 32 is provided to be driven by an electric motor 35, directly or indirectly, preferably at constant angular velocity for each of the opening and closing operations.
- the drive device 30 also comprises an output member 34 in the form of a connecting rod, one end of which comprises the point of attachment 22 to the secondary body 14, which can move in translation in the direction 11.
- the connecting rod 34 is substantially parallel to this direction 11, and intended to remain during the opening and closing operations, even if oscillations of a few degrees can be encountered around the attachment point 22 forming pivot connection, without departing from the scope of the invention.
- the device 30 comprises a mechanical movement transmission system 40 between the connecting rod 34 and the rotary input shaft 32, this mechanical system 30 being generally designed so as to obtain a variable translational speed of the point of attachment. 22 during a rotation at angular speed constant of the rotary input shaft 32, during an opening operation and during a closing operation of the electrical equipment.
- This variable translation speed is defined in the direction 11, relative to the fixed body 8 of the disconnector.
- the mechanical system 40 comprises two elements 44, 46, the first 44 being integral in rotation with the shaft 32, and the second 46 being integral with the connecting rod 34. They can each take an overall shape of a triangle, being arranged parallel facing one another, orthogonally to the axis 48 of the shaft 32 and parallel to the direction 11.
- the first element 44 has a groove 50 in the form of an arc of a circle, arranged near the opposite side to the apex receiving the shaft 32.
- This groove 50 can be made on one of the faces of the element 44, or alternatively to be through.
- the first element 44 comprises a pin member 52 protruding from one of the faces towards the second element 46, parallel to the direction of the axis 48.
- the pin 52 is located between the groove 50 and same axis 48 of the rotary input shaft 32.
- the second element 46 has a groove 56 in the form of an arc of a circle, arranged near the opposite side to the vertex carrying a pin member 58.
- This groove 56 can also be made on one of the faces of the element 46, or alternatively be through.
- the pawn 58 protrudes from one of the faces towards the first element 44, parallel to the direction of the axis 48.
- each element 44, 46 thus forms a kind of cam cooperating with its associated member 58, 52 which performs a similar function to that of a cam follower.
- the drive of one of the two elements 44, 46 by the other of the elements is carried out by pressing one of the pin members 52, 58 in the bottom of its associated groove and by simultaneously moving the other peg member into its associated groove.
- the drive element of the transmission is the support of the pin member in the bottom of its associated groove
- the simultaneous movement of the other member pin in its associated groove is more to maintain a substantially constant orientation of the rod 34 fixedly supported by the element 46, namely an orientation substantially parallel to the sliding direction 11.
- the second element 46 also maintains a substantially identical orientation during its movement observed during closing and opening operations.
- the design of the mechanical transmission system 40 is such that the two pin members 52, 58 respectively describe, during an opening operation and during a closing operation of the electrical equipment, two concentric circular concentric paths 62, 64 centered on the axis 46.
- the mechanical system 40 having a positive action between the input rotary shaft 32 and the connecting rod 34, is such that the arcuate paths are identical for the opening and closing phases.
- the disconnector 1 is shown in the open position, in which the moving assembly 6 is at a distance from the fixed contacts 4a, 4b.
- the pin 52 is supported in the bottom of the groove 56, at one end thereof said end of the counterclockwise direction relative to the axis 48.
- the pin 58 is supported in the bottom of the groove 50, at one end thereof also said end of the counterclockwise direction with respect to the axis 48.
- the rotation of the shaft 32 is carried out counterclockwise. From the beginning of this rotation, the first element 44 rotates in the same direction, and drives the second element 46 by the support of the pin 52 in the groove 56. At the same time, the pin 58 moves in the groove 50, in the direction of the other end thereof, said end of the clockwise direction relative to the axis 48.
- This displacement of the pin 58 in the groove 50 essentially allows here to maintain a substantially identical orientation of the second element 46 in its plan of evolution during its drive by the pin 52, in order to maintain a substantially identical to the rod 34. The latter therefore moves only along its axis, possibly being subject to small angular oscillations around the point of attachment 22.
- the displacement of the attachment point 22 in the direction 11 towards the fixed contacts 4a, 5a causes only the displacement of the secondary body 14 in the bore 12, until the contact with the bottom 17.
- This state represented on the figure 3a corresponds to that of the point P1 of the graph of the figure 4 , showing that the displacement of the main body 9 of the electrically conductive assembly 6, shown schematically by the solid line curve, has meanwhile not yet begun.
- the spring 16 decompresses until contact of the body 14 with the bottom 17.
- the configuration of the figure 3a the one adopted in the open position. The closing operation would then begin with the secondary body 14 in contact with the bottom 17 of the bore 12.
- the rotation of the shaft 32 is continued at the same angular speed, always by the support of the pin 52 in the groove 56, which causes the simultaneous movement of the main body 9 and the secondary body 14 of the moving assembly 6.
- the pawn 52 moving according to the circular arc trajectory 62, its linear speed is constant, which is conducive to obtaining a linear speed of constant translation of the attachment point 22 until the configuration of the mechanical system 30 ' reverse. Inversion here means that the driving element of the displacement of the second element 46 by the first element 44 is no longer the support of the pin 52 in the groove 56, but the support of the other pin 58 in the groove 56. the bottom of the groove 50.
- the trajectory 64 in an arc of the pin 58, centered on the axis 48 in the same way as the trajectory 62 of the pin 52, has a radius greater than that of the latter trajectory, which results in an accelerated translation speed of the point of attachment 22, after passing through point P2.
- This speed is moreover preferably substantially constant until the end of the schematized closing operation on the figure 3c when the point of attachment 22 reaches the point P3.
- This last figure thus shows the disconnector in the closed position, in which the electrical contacts 4a, 4b, 5a, 5b cooperate in pairs.
- the pin 52 is supported in the bottom of the groove 56, at the end of the clockwise direction relative to the axis 48, and the pin 58 is supported in the bottom of the groove 50, also at the end of the clockwise direction relative to the axis 48.
- the slower speed applied at the start of the closing operation makes it possible to limit the mechanical wear of the elements moving relatively relative to one another, while the faster speed at the end of the closing operation. makes it possible to limit the electrical wear of the arcing contacts 5a, 5b.
- the linear speed of the moving elements is relatively slow and constant, which makes it possible to limit the mechanical wear of the disconnector.
- the permanent contacts 4a, 4b At the moment when the attachment point 22 reaches the point P4, instant represented on the figure 5a the permanent contacts 4a, 4b have been separated, but the arcing contacts 5a, 5b are still in contact. It is at this moment that the configuration of the mechanical system 40 is reversed.
- inversion means that the driving element of the displacement of the second element 46 by the first element 44 is no longer the support of the pin 52 in the groove 56, but the support of the other pin 58 in the bottom of the groove 50.
- This inversion generates an acceleration of the linear translational velocity of the attachment point 22, which will be kept substantially constant until the open position shown on FIG. figure 5e , corresponding to point P7 of the graph of the figure 6 , at which the drive device 30 adopts a configuration identical to that adopted at point P0 of the graph of FIG. figure 4 .
- the main body 9 remains a moment in position, without being driven by the secondary body 14 which continues its course.
- this causes the spring 16 to store energy by shifting the secondary body 14 relative to the main body 9 towards a second end position opposite to the aforementioned first end position.
- the figure 5b shows the state of the device 30 with the highly compressed spring 16, and the electrical arcing contacts still in contact.
- this second position after the body 14 has been moved by a determined distance relative to the body 9, it unlocks the stop means 100 in a manner which will also be exemplified below.
- the two bodies 9, 14 are driven substantially at the same linear speed, to the point P6 of the point of attachment 22.
- the main body stops because it is in abutment on the fixed body 8, and the secondary body 14 continues its course to the point P7, corresponding to the moment when the pin 52 comes to rest in the bottom of the groove 56, at its end of the sense counterclockwise along the axis 48.
- the disconnector is at this instant in the open state, identical to that shown on the figure 1 .
- the abutment means 100 which, as a reminder, help to ensure that during an opening operation, the spring 16 can first store energy by displacement of the secondary body 14 relative to the main body 9 temporarily blocked by these means 100, then release the stored energy to cause acceleration of the main body 9.
- the abutment means 100 comprise radial pins 102 housed in corresponding orifices 104 formed in the fixed body 8.
- the pins 102 are coupled to resilient return means of the spring type, pushing them radially inwardly so as to project into the housing 10.
- the main body 9 has meanwhile longitudinal slots 106 at its portion located opposite the contacts 4b, 5b, slots in which slide the ends of the pins 102.

Description
La présente invention se rapporte au domaine des appareillages électriques de coupure, en particulier du type sectionneur ou sectionneur de terre, de préférence haute tension.The present invention relates to the field of electrical switchgear, in particular the disconnector or earthing switch type, preferably high voltage.
Plus précisément, l'invention concerne un ensemble mobile électriquement conducteur de l'appareillage, destiné à être mis en mouvement par un dispositif d'entraînement et étant classiquement équipé d'un contact permanent et d'un contact d'arc électrique.More specifically, the invention relates to an electrically conductive moving assembly of the apparatus, intended to be set in motion by a drive device and being conventionally equipped with a permanent contact and an electric arc contact.
Classiquement et de façon connue de l'homme du métier, l'ensemble électriquement conducteur d'un l'appareillage électrique de coupure du type sectionneur ou sectionneur de terre est déplacé à vitesse de translation constante durant chaque opération d'ouverture et durant chaque opération de fermeture.Conventionally and in a manner known to those skilled in the art, the electrically conductive assembly of an electrical switchgear of the disconnector or earthing switch type is moved at constant translation speed during each opening operation and during each operation. closure.
Au cours de ces opérations effectuées à répétition, l'ensemble conducteur, qui prend généralement la forme d'un cylindre équipé d'un contact permanent et d'un contact d'arc électrique, subit des sollicitations mécaniques et électriques qui engendrent progressivement sa dégradation. Ce phénomène s'observe également sur l'autre contact permanent et sur l'autre contact d'arc électrique de l'appareillage.During these repeated operations, the conductor assembly, which generally takes the form of a cylinder equipped with a permanent contact and an electric arc contact, undergoes mechanical and electrical stresses that gradually lead to its degradation. This phenomenon is also observed on the other permanent contact and on the other arcing contact of the apparatus.
Ces problèmes génèrent la création de particules, de la pollution, de l'échauffement, et affectent la durée de vie de l'appareillage électrique.These problems generate the creation of particles, pollution, heating, and affect the life of the electrical equipment.
En particulier, lors d'une opération d'ouverture, si la vitesse de l'ensemble électriquement conducteur est trop rapide, elle entraîne une usure mécanique des contacts permanents. Cela pourrait inciter à réduire la vitesse de l'ensemble électriquement conducteur, mais il se produirait en contrepartie une usure électrique des contacts d'arc.In particular, during an opening operation, if the speed of the electrically conductive assembly is too fast, it causes mechanical wear of the permanent contacts. This could be an incentive to reduce the speed of the electrically conductive assembly, but in return there would be electrical wear of the arcing contacts.
Pour tenter de résoudre ce problème, le document
Enfin, le couplage du ressort au contact fixe nécessite une augmentation sensible de l'encombrement de la zone, ce qui se traduit par un accroissement pénalisant de l'encombrement global de l'appareillage électrique de coupure, qui est pourtant un critère jugé primordial sur les appareillages actuels.Finally, the coupling of the spring to the fixed contact requires a significant increase in the size of the area, which results in a penalizing increase in the overall size of the electrical switchgear, which is nevertheless a criterion considered essential on current equipment.
L'invention a donc pour but de remédier au moins partiellement aux inconvénients mentionnés ci-dessus, relatifs aux réalisations de l'art antérieur.The invention therefore aims to at least partially overcome the disadvantages mentioned above, relating to the achievements of the prior art.
Pour ce faire, l'invention a pour objet un appareillage électrique de coupure, en particulier un sectionneur ou un sectionneur de terre, comprenant un ensemble mobile électriquement conducteur comportant un corps principal électriquement conducteur intégrant un contact permanent ainsi qu'un contact d'arc électrique.To do this, the subject of the invention is an electrical switchgear, in particular a disconnector or an earthing switch, comprising an electrically conductive moving assembly comprising an electrically conductive main body incorporating a permanent contact and an arc contact. electric.
Selon l'invention, ledit ensemble mobile électriquement conducteur comporte également un corps secondaire monté mobile à coulissement relativement audit corps principal selon une direction de déplacement de cet ensemble électriquement conducteur, ledit corps secondaire étant destiné à être relié à un point d'attache d'un dispositif d'entraînement dudit ensemble mobile électriquement conducteur, ce dernier comportant en outre des moyens élastiques de rappel interposés entre ledit corps principal et ledit corps secondaire, et ledit appareillage étant conçu de sorte qu'au cours d'une opération d'ouverture, lesdits moyens élastiques de rappel puissent d'abord emmagasiner de l'énergie par déplacement du corps secondaire relativement au corps principal, puis libérer l'énergie emmagasinée pour provoquer une accélération dudit corps principal.According to the invention, said movable electrically conductive assembly also comprises a secondary body slidably mounted relative to said main body in a direction of movement of said electrically conductive assembly, said secondary body being intended to be connected to an attachment point of a drive device of said movable electrically conductive assembly, the latter further comprising resilient return means interposed between said main body and said secondary body, and said apparatus being designed so that during an opening operation, said elastic return means can first store energy by displacement of the secondary body relative to the main body, then release the stored energy to cause an acceleration of said main body.
Ainsi, l'invention est tout d'abord remarquable en ce qu'elle permet de faire varier la vitesse du corps principal de l'ensemble mobile, au cours d'une même opération d'ouverture, par le biais de l'accélération provoquée par la libération d'énergie des moyens élastiques de rappel. Par conséquent, cette variation maîtrisée peut être déterminée de manière à limiter au mieux les usures mécanique et électrique de l'ensemble électriquement conducteur. A cet égard, la libération d'énergie est préférentiellement amorcée après la séparation des contacts permanents, et pendant la séparation des contacts d'arc électrique, c'est-à-dire amorcée à l'instant précis de la séparation des contacts d'arcs ou avant ce même instant, et achevée après qu'ils soient séparés. De ce fait, la vitesse du contact d'arc mobile embraqué sur l'ensemble électriquement conducteur est encore plus élevée durant cette phase critique de l'opération d'ouverture, ce qui limite les dégradations dues aux sollicitations électriques.Thus, the invention is first of all remarkable in that it makes it possible to vary the speed of the main body of the moving assembly, during the same opening operation, by means of the acceleration caused. by the release of energy from the elastic return means. Consequently, this controlled variation can be determined in such a way as to best limit the mechanical and electrical wear of the electrically conductive assembly. In this respect, the release of energy is preferentially initiated after the separation of the permanent contacts, and during the separation of the arcing contacts, that is to say initiated at the precise moment of the separation of the contacts. arcs or before that moment, and completed after they are separated. As a result, the speed of the moving arc contact embossed on the electrically conductive assembly is even higher during this critical phase of the opening operation, which limits the damage due to electrical stresses.
Bien entendu, l'invention est également avantageuse en ce sens qu'elle permet une variation de la vitesse du corps principal de l'ensemble mobile, tout en déplaçant ledit point d'attache à vitesse de translation constante. Par conséquent, le dispositif d'entraînement de cet ensemble conducteur peut avantageusement intégrer un moteur piloté à vitesse constante, même si une vitesse variable pourrait être mise en oeuvre, sans sortir du cadre de l'invention.Of course, the invention is also advantageous in that it allows a variation in the speed of the main body of the moving assembly, while moving said attachment point constant speed of translation. Therefore, the driving device of this conductive assembly can advantageously incorporate a motor driven at a speed constant, even if a variable speed could be implemented, without departing from the scope of the invention.
Par ailleurs, contrairement à la solution décrite dans le document
Enfin, la solution proposée permet de réduire l'encombrement global de l'appareillage par rapport à ceux rencontrés dans l'art antérieur. Effectivement, dans l'art antérieur, la modification apportée au contact fixe pour le rendre légèrement mobile entraîne une augmentation sensible du dimensionnement, notamment pour des besoins de guidage en translation de ce contact. En revanche, lorsque l'élément accéléré est agencé du côté des électrodes / conducteurs mobiles, sur l'ensemble conducteur, l'impact sur le dimensionnement est largement plus faible car cet ensemble dispose déjà d'un encombrement important, notamment une longueur importante pour assurer son guidage en translation. Cet encombrement important peut donc avantageusement être mis à profit pour y intégrer ledit corps secondaire et les moyens élastiques de rappel, sans trop d'impact sur le dimensionnement global, voire avec un impact nul sur ce dimensionnement.Finally, the proposed solution reduces the overall size of the equipment compared to those encountered in the prior art. Indeed, in the prior art, the modification made to the fixed contact to make it slightly mobile causes a significant increase in the dimensioning, especially for purposes of translational guidance of this contact. On the other hand, when the accelerated element is arranged on the side of the mobile electrodes / conductors, on the driver assembly, the impact on the dimensioning is much smaller because this assembly already has a large bulk, notably a long length for ensure its guidance in translation. This large space can therefore advantageously be used to integrate said secondary body and the elastic return means, without much impact on the sizing overall, or even with no impact on this dimensioning.
De préférence, l'appareillage comporte des moyens de butée permettant, au cours d'une opération d'ouverture, de bloquer le mouvement de translation dudit corps principal par rapport à un corps fixe de l'appareillage, ledit corps secondaire étant équipé de moyens de déverrouillage conçus pour libérer lesdits moyens de butée après que ledit corps secondaire ait été déplacé relativement au corps principal, selon une distance prédéterminée.Preferably, the apparatus comprises stop means allowing, during an opening operation, to block the translational movement of said main body relative to a fixed body of the apparatus, said secondary body being equipped with means unlocking means adapted to release said abutment means after said secondary body has been moved relative to the main body by a predetermined distance.
De préférence, lesdits moyens élastiques de rappel comprennent au moins un ressort de compression ou de traction.Preferably, said elastic return means comprise at least one compression or traction spring.
De préférence, lesdits moyens de butée sont agencés sur un corps fixe de l'appareillage et sur le corps principal de l'ensemble mobile électriquement conducteur.Preferably, said stop means are arranged on a fixed body of the apparatus and on the main body of the movable electrically conductive assembly.
L'appareillage électrique pourrait également présenter des moyens élastiques de rappel de fonction similaire à celle décrite ci-dessus, visant à accélérer les contacts lors d'une phase précise de l'opération de fermeture. Cela pourrait par exemple s'effectuer en remplaçant le ressort de compression par un ressort de traction. Si une solution avec plusieurs ressorts est donc envisagée, il est cependant possible d'utiliser le même ressort pour assurer l'accélération requise durant l'ouverture et la fermeture, respectivement après sa compression et sa mise en traction, ou inversement.The electrical equipment could also have resilient means of return function similar to that described above, to accelerate the contacts during a specific phase of the closing operation. This could for example be done by replacing the compression spring with a tension spring. If a solution with several springs is therefore envisaged, however, it is possible to use the same spring to ensure the required acceleration during opening and closing, respectively after compression and traction, or vice versa.
De préférence, l'appareillage électrique comprend également un dispositif d'entraînement dudit ensemble mobile, ce dispositif comportant un arbre rotatif d'entrée ainsi qu'un organe de sortie comportant ledit point d'attache audit ensemble électriquement conducteur, ledit point d'attache étant mobile à translation selon la direction de déplacement dudit ensemble électriquement conducteur. De plus, ce dispositif d'entraînement comporte un système mécanique de transmission de mouvement entre ledit point d'attache et ledit arbre rotatif d'entrée, ce système mécanique étant conçu de manière à obtenir une vitesse variable du point d'attache lors d'une rotation à vitesse angulaire constante dudit arbre rotatif d'entrée, au cours d'une opération d'ouverture et/ou au cours d'une opération de fermeture de l'appareillage électrique.Preferably, the electrical equipment also comprises a drive device of said mobile assembly, this device comprising a rotary input shaft and an output member having said attachment point to said electrically conductive assembly, said attachment point being movable in translation in the direction of movement of said electrically conductive assembly. In addition, this driving device comprises a mechanical system for transmitting motion between said point of attachment and said rotary input shaft, this mechanical system being designed to obtain a variable speed of the point of attachment when a constant angular speed rotation of said rotary input shaft, during an opening operation and / or during a closing operation of the electrical equipment.
Néanmoins, tout dispositif d'entraînement conventionnel peut être employé, sans sortir du cadre de l'invention.Nevertheless, any conventional drive device can be used without departing from the scope of the invention.
Cependant, la conception particulière décrite ci-dessus rompt avec les dispositifs d'entraînement classiques de l'art antérieur, prévoyant une vitesse de translation constante du point d'attache au cours d'une même opération d'ouverture et au cours d'une même opération de fermeture de l'appareillage électrique. Ici, le système mécanique permet effectivement de faire varier la vitesse de translation du point d'attache au cours de l'une et/ou de l'autre de ces opérations. Par conséquent, cette variation maîtrisée peut être déterminée de manière à limiter au mieux les usures mécanique et électrique de l'ensemble électriquement conducteur. Pour l'opération d'ouverture, cette possible variation s'ajoute à celle spécifique à la présente invention, procurée par l'accélération du corps principal de l'ensemble mobile via lesdits moyens élastiques de rappel.However, the particular design described above breaks with the conventional drive devices of the prior art, providing a constant speed of translation of the point of attachment during the same opening operation and during a same closing operation of the electrical equipment. Here, the mechanical system effectively makes it possible to vary the speed of translation of the point of attachment during one and / or the other of these operations. Consequently, this controlled variation can be determined in such a way as to best limit the mechanical and electrical wear of the electrically conductive assembly. For the opening operation, this possible variation is added to that specific to the present invention, provided by the acceleration of the main body of the moving assembly via said elastic return means.
A titre d'exemple, lors de la phase initiale d'une opération d'ouverture, la vitesse de l'ensemble électriquement conducteur peut être lente, jusqu'à la séparation des contacts permanents afin de limiter l'usure mécanique de ceux-ci, puis s'élever ensuite pour limiter l'usure électrique des contacts d'arc.For example, during the initial phase of an opening operation, the speed of the electrically conductive assembly can be slow, until the separation of the permanent contacts in order to limit the mechanical wear thereof then rise to limit the electrical wear of the arcing contacts.
De même, durant une opération de fermeture, il peut être intéressant de débuter la mise en mouvement lentement afin d'éviter l'usure mécanique, puis d'accélérer ensuite pour limiter l'usure électrique des contacts d'arc. Il pourrait également être fait en sorte de limiter la vitesse lors de l'emboîtement des contacts permanents, après la mise en contact des contacts d'arc.Similarly, during a closing operation, it may be advantageous to start the movement slowly to avoid mechanical wear, and then accelerate to limit the electrical wear of the arcing contacts. It could also be done so as to limit the speed during the engagement of the permanent contacts, after the contacting of the arcing contacts.
D'une manière plus générale, pour ce qui concerne les sollicitations électriques, la variation de la vitesse de l'organe de sortie peut être adaptée pour limiter au mieux les effets néfastes des courants induits, capacitifs, de transfert de barres, et de fermeture sur court-circuit.In a more general manner, with regard to electrical stresses, the variation of the speed of the output member can be adapted to limit at best the harmful effects of the induced, capacitive, bar transfer and closure currents. on short circuit.
Quoi qu'il en soit, la variation de la vitesse durant chacune des opérations d'ouverture et de fermeture peut être fixée par l'homme du métier, en fonction des besoins et des contraintes rencontrées. Il suffit d'adapter la conception du système mécanique de transmission, qui, par définition, est une solution mécanique facilement réalisable, fiable et peu coûteuse, au contraire par exemple d'un simple variateur de vitesse commandant la fréquence du courant statorique du moteur électrique. Cette dernière solution peut néanmoins être retenue, sans sortir du cadre de l'invention.In any case, the variation of the speed during each of the opening and closing operations can be fixed by those skilled in the art, according to the needs and constraints encountered. It suffices to adapt the design of the mechanical transmission system, which by definition is a mechanical solution that is easily achievable, reliable and expensive, unlike for example a simple speed controller controlling the frequency of the stator current of the electric motor. This last solution can nevertheless be retained, without departing from the scope of the invention.
Comme évoqué ci-dessus, il est indiqué que la variation de la vitesse de translation de l'organe de sortie s'obtient avec une vitesse angulaire constante de l'arbre d'entrée, facilement applicable à l'aide d'un moteur électrique classique. Néanmoins, il pourrait être appliqué une vitesse angulaire variable à l'arbre d'entrée. A titre indicatif, il est noté que l'arbre peut être relié de manière directe ou indirecte au moteur électrique d'entraînement, voire constituer l'arbre de sortie de ce moteur. Enfin, en cas de panne moteur, l'arbre rotatif d'entrée peut être actionné manuellement par une manivelle, tel que cela est connu de l'homme du métier. Lors de cet actionnement, l'opérateur bénéficiera avantageusement de l'effet de démultiplication et/ou de surmultiplication de vitesse conféré mécaniquement par ledit système spécifique de transmission.As mentioned above, it is stated that the variation of the translational speed of the output member is obtained with a constant angular velocity of the input shaft, easily applicable with the aid of an electric motor. classic. Nevertheless, a variable angular velocity could be applied to the input shaft. As an indication, it is noted that the shaft can be connected directly or indirectly to the electric drive motor, or even be the output shaft of the engine. Finally, in case of engine failure, the input rotary shaft can be manually operated by a crank, as is known to those skilled in the art. During this actuation, the operator will advantageously benefit from the reduction effect and / or overdrive speed mechanically conferred by said specific transmission system.
Le système mécanique de transmission prend donc préférentiellement la forme d'une liaison à action positive entre l'arbre rotatif d'entrée et l'organe de sortie comprenant le point d'attache. Par action positive, il est signifié qu'il existe un lien bidirectionnel entre ces deux derniers éléments, impliquant en particulier qu'à toute position du point d'attache correspond une position angulaire de l'arbre d'entrée, et inversement, et ce en tout point entre les deux positions extrêmes.The mechanical transmission system therefore preferably takes the form of a positive-acting link between the rotary input shaft and the output member comprising the attachment point. By positive action, it is meant that there exists a bidirectional link between these two last elements, implying in particular that at any position of the point of attachment corresponds an angular position of the tree. of entry, and vice versa, and in all points between the two extreme positions.
De préférence, ledit système mécanique comporte au moins deux éléments pourvus chacun d'une rainure et d'un organe formant pion logé mobile dans la rainure de l'autre des deux éléments. Chaque élément forme donc une sorte de came coopérant avec son organe associé qui remplit quant à lui une fonction assimilable à celle d'un suiveur de came. Cette technologie s'avère particulièrement fiable et facilement réalisable. Naturellement, le nombre, la disposition et la forme des éléments, des rainures et des organes formant pion peuvent être modulés en fonction des variations de vitesse désirées.Preferably, said mechanical system comprises at least two elements each provided with a groove and a movable pin member movable in the groove of the other of the two elements. Each element thus forms a kind of cam cooperating with its associated member which performs a similar function to that of a cam follower. This technology is particularly reliable and easily achievable. Naturally, the number, arrangement and shape of the elements, grooves and peg members can be modulated according to the desired speed variations.
De préférence, le système mécanique de transmission est conçu de sorte que l'entraînement de l'un des deux éléments par l'autre des éléments s'effectue par appui de l'un des organes formant pion dans le fond de sa rainure associée, et par déplacement simultané de l'autre organe formant pion dans sa rainure associée. Encore plus préférentiellement, il est prévu que l'élément moteur de la transmission soit l'appui de l'organe formant pion dans le fond de sa rainure associée, le déplacement simultané de l'autre organe formant pion dans sa rainure associée servant davantage à maintenir une orientation désirée du ou des éléments en présence.Preferably, the mechanical transmission system is designed so that the driving of one of the two elements by the other of the elements is carried out by pressing one of the peg members into the bottom of its associated groove, and by simultaneously moving the other peg member into its associated groove. Even more preferably, it is provided that the driving element of the transmission is the support of the peg member in the bottom of its associated groove, the simultaneous movement of the other peg member in its associated groove serving more to maintain a desired orientation of the element or elements involved.
De préférence, le système mécanique de transmission est conçu de sorte qu'au cours d'une opération d'ouverture et/ou au cours d'une opération de fermeture de l'appareillage électrique, chaque organe formant pion passe au moins une fois de sa configuration en appui contre le fond de sa rainure associée à sa configuration en déplacement dans sa rainure associée, ou inversement. Ce changement de configuration est naturellement propice à l'obtention d'un changement de vitesse linéaire de l'organe de sortie. Préférentiellement, ces changements s'effectuent de manière simultanée, c'est-à-dire que l'instant où l'un des deux organes formant pion quitte le fond de sa rainure associée correspond à l'instant où l'autre organe entre en contact avec le fond de sa rainure associée.Preferably, the mechanical transmission system is designed so that during an opening operation and / or during a closing operation of the electrical equipment, each organ pin forming passes at least once of its configuration in abutment against the bottom of its groove associated with its configuration moving in its associated groove, or vice versa. This configuration change is naturally conducive to obtaining a linear speed change of the output member. Preferably, these changes are made simultaneously, that is to say that the moment when one of the two pawn members leaves the bottom of its associated groove corresponds to the moment when the other member enters into position. contact with the bottom of its associated groove.
De préférence, le système mécanique de transmission est conçu de sorte que les deux organes formant pion décrivent respectivement, au cours d'une opération d'ouverture et/ou au cours d'une opération de fermeture de l'appareillage électrique, deux trajectoires concentriques en arc de cercle centrées sur un axe dudit arbre rotatif d'entrée. Ici aussi, cela est naturellement propice à l'obtention d'un changement de vitesse linéaire de l'organe de sortie, puisqu'en étant situés à des distances différentes de l'axe de l'arbre d'entrée, les deux pions présentent nécessairement des vitesses linéaires distinctes lors de la rotation de cet arbre d'entrée.Preferably, the mechanical transmission system is designed so that the two pawn members respectively describe, during an opening operation and / or during a closing operation of the electrical equipment, two concentric trajectories respectively. in an arc centered on an axis of said rotary input shaft. Here too, this is naturally conducive to obtaining a linear speed change of the output member, since being located at different distances from the axis of the input shaft, the two pins present necessarily different linear speeds during the rotation of this input shaft.
De préférence, l'un des deux éléments du système mécanique de transmission est solidaire en rotation dudit arbre rotatif d'entrée, et l'autre des deux éléments porte une bielle sur laquelle se trouve ledit point d'attache.

En référence tout d'abord aux
Le sectionneur 1 comprend une chambre de coupure 2 montrée uniquement partiellement, enfermée dans une enceinte contenant un gaz isolant tel que du gaz SF6 ou tout autre mélange gazeux réputé approprié. La chambre 2 renferme un contact permanent fixe 4a, ainsi qu'un contact fixe d'arc électrique 5a, situé radialement vers l'intérieur par rapport au contact permanent 4a. En outre, elle renferme un ensemble mobile électriquement conducteur 6, relié électriquement à un corps fixe 8 dans lequel il est mobile à translation, selon une direction de déplacement représentée par la flèche 11. Cet ensemble 6 présente une extrémité équipée d'un contact permanent mobile 4b, et d'un contact mobile d'arc électrique 5b, destinés à coopérer avec les contacts 4a, 5a susmentionnés.The
L'ensemble 6 prend globalement la forme d'un cylindre mobile à coulissement, comme le piston d'un vérin, dans un logement cylindrique 10 du corps 8. Il comporte un corps principal 9 électriquement conducteur, formant un corps extérieur, et intégrant le contact permanent 4b ainsi que le contact d'arc électrique 5b. A l'intérieur de ce corps principal 9 est pratiqué un alésage débouchant 12 orienté selon la direction 11, et logeant à coulissement un corps secondaire 14. Ainsi, le corps secondaire 14 est monté mobile à coulissement relativement au corps principal 9 selon la direction de déplacement 11.The
De plus, l'ensemble électriquement conducteur 6 comporte des moyens élastiques de rappel, tel qu'un ressort de compression 16, forçant le corps secondaire 14 à se déplacer en direction d'une première position d'extrémité par rapport au corps principal, correspondant à la position dans laquelle il se situe au plus près du contact permanent fixe 4a. Cette première position, vers laquelle le ressort 16 tend à pousser le corps secondaire 14, correspond également à une position dans laquelle ce corps 14 se situe dans le fond 17 de l'alésage débouchant 12.In addition, the electrically
Pour ce faire, le ressort 16 disposé autour du corps secondaire 14 prend appui à l'une de ses extrémités sur une collerette 18 de ce corps, et prend appui à l'autre de ses extrémités sur une bague 20 montée fixement dans l'alésage débouchant 12 du corps 9.To do this, the
Ainsi, lorsque le corps secondaire 14 se déplace selon la direction 11 dans le sens de l'ouverture, conduisant à l'écartement des contacts électriques, il transmet ce mouvement au corps principal 9 intégrant les contacts, par le biais de la réaction du ressort de compression sur la bague 20. Inversement, lorsque le corps secondaire 14 se déplace selon la direction 11 dans le sens de la fermeture, conduisant à un rapprochement des contacts électriques, il transmet ce mouvement au corps principal 9 par appui de son extrémité dans le fond 17 de l'alésage 12.Thus, when the
Pour mettre le corps secondaire en mouvement, afin de mettre en oeuvre les opérations d'ouverture et de fermeture du sectionneur, ce corps secondaire 14 est relié à un point d'attache 22 d'un dispositif d'entraînement 30, dont une réalisation préférée va à présent être décrite. Néanmoins, toute autre réalisation conventionnelle pourrait être retenue pour entraîner le point d'attache 22, sans sortir du cadre de l'invention.To put the secondary body in motion, in order to implement the opening and closing operations of the disconnector, this body secondary 14 is connected to an
Le dispositif 30 comprend un arbre rotatif d'entrée 32, sensiblement orthogonal à la direction de coulissement 11 de l'ensemble mobile 6. Comme cela a été montré schématiquement sur la
Le dispositif d'entraînement 30 comporte également un organe de sortie 34 en forme de bielle, dont l'une des extrémités comporte le point d'attache 22 au corps secondaire 14, mobile à translation selon la direction 11. D'ailleurs, la bielle 34 est sensiblement parallèle à cette direction 11, et prévue pour le rester durant les opérations d'ouverture et de fermeture, même si des oscillations de quelques degrés peuvent être rencontrées autour du point d'attache 22 formant liaison pivot, sans sortir du cadre de l'invention.The
En outre, le dispositif 30 comporte un système mécanique de transmission de mouvement 40 entre la bielle 34 et l'arbre rotatif d'entrée 32, ce système mécanique 30 étant globalement conçu de manière à obtenir une vitesse de translation variable du point d'attache 22 lors d'une rotation à vitesse angulaire constante de l'arbre rotatif d'entrée 32, au cours d'une opération d'ouverture et au cours d'une opération de fermeture de l'appareillage électrique. Cette vitesse de translation variable est définie selon la direction 11, par rapport au corps fixe 8 du sectionneur.In addition, the
Ici, le système mécanique 40 comporte deux éléments 44, 46, le premier 44 étant solidaire en rotation de l'arbre 32, et le second 46 étant solidaire de la bielle 34. Ils peuvent prendre chacun une forme globale de triangle, en étant disposés parallèlement en regard l'un de l'autre, orthogonalement à l'axe 48 de l'arbre 32 et parallèlement à la direction 11.Here, the
Le premier élément 44 présente une rainure 50 en forme d'arc de cercle, agencée à proximité du côté opposé au sommet recevant l'arbre 32. Cette rainure 50 peut être réalisée sur l'une des faces de l'élément 44, ou alternativement être traversante. De plus, le premier élément 44 comporte un organe formant pion 52, faisant saillie de l'une des faces en direction du second élément 46, parallèlement à la direction de l'axe 48. Le pion 52 se situe entre la rainure 50 et ce même axe 48 de l'arbre rotatif d'entrée 32.The
De manière analogue, le second élément 46 présente une rainure 56 en forme d'arc de cercle, agencée à proximité du côté opposé au sommet portant un organe formant pion 58. Cette rainure 56 peut aussi être réalisée sur l'une des faces de l'élément 46, ou alternativement être traversante. De plus, le pion 58 fait saillie de l'une des faces en direction du premier élément 44, parallèlement à la direction de l'axe 48.Similarly, the
A l'état assemblé, le pion 52 est logé mobile à coulissement dans la rainure 56, tandis que le pion 58 est logé mobile à coulissement dans la rainure 50. Chaque élément 44, 46 forme donc une sorte de came coopérant avec son organe associé 58, 52 qui remplit quant à lui une fonction assimilable à celle d'un suiveur de came.In the assembled state, the
Avec cette configuration, il est prévue que l'entraînement de l'un des deux éléments 44, 46 par l'autre des éléments s'effectue par appui de l'un des organes formant pion 52, 58 dans le fond de sa rainure associée, et par déplacement simultané de l'autre organe formant pion dans sa rainure associée. Plus précisément, il est prévu que l'élément moteur de la transmission soit l'appui de l'organe formant pion dans le fond de sa rainure associée, le déplacement simultané de l'autre organe formant pion dans sa rainure associée servant davantage à maintenir une orientation sensiblement constante de la bielle 34 portée fixement par l'élément 46, à savoir une orientation sensiblement parallèle à la direction de coulissement 11. A cet égard, il est noté que le second élément 46 conserve également une orientation sensiblement identique durant son mouvement observé lors des opérations de fermeture et d'ouverture.With this configuration, it is provided that the drive of one of the two
Enfin, il est indiqué que la conception du système mécanique de transmission 40 est telle que les deux organes formant pion 52, 58 décrivent respectivement, au cours d'une opération d'ouverture et au cours d'une opération de fermeture de l'appareillage électrique, deux trajectoires 62, 64 concentriques en arc de cercle centrées sur l'axe 46. Le système mécanique 40, à action positive entre l'arbre rotatif d'entrée 32 et la bielle 34, est tel que les trajectoires en arc de cercle sont identiques pour les phases d'ouverture et de fermeture.Finally, it is stated that the design of the

La rotation de l'arbre 32 s'effectue dans le sens antihoraire. Dès le début de cette rotation, le premier élément 44 tourne dans le même sens, et entraîne le second élément 46 par l'appui du pion 52 dans la rainure 56. Dans le même temps, le pion 58 se déplace dans la rainure 50, en direction de l'autre extrémité de celle-ci, dite extrémité du sens horaire par rapport à l'axe 48. Ce déplacement du pion 58 dans la rainure 50 permet ici essentiellement de conserver une orientation sensiblement identique du second élément 46 dans son plan d'évolution durant son entraînement par le pion 52, afin de conserver une orientation sensiblement identique de la bielle 34. Cette dernière se déplace donc uniquement selon son axe, en étant éventuellement sujet à de faibles oscillations angulaires autour du point d'attache 22.The rotation of the
Durant la phase initiale de l'opération de fermeture, le déplacement du point d'attache 22 dans la direction 11 vers les contacts fixes 4a, 5a n'entraîne que le déplacement du corps secondaire 14 dans l'alésage 12, jusqu'au contact avec le fond 17. Cet état représenté sur la
La rotation de l'arbre 32 est poursuivie à la même vitesse angulaire, toujours par l'appui du pion 52 dans la rainure 56, ce qui entraîne le déplacement simultané de corps principal 9 et du corps secondaire 14 de l'ensemble mobile 6. Le pion 52 se déplaçant selon la trajectoire en arc de cercle 62, sa vitesse linéaire est constante, ce qui est propice à l'obtention d'une vitesse linaire de translation constante du point d'attache 22 jusqu'à ce que la configuration du système mécanique 30 s'inverse. Par inversion, on entend ici le fait que l'élément moteur du déplacement du second élément 46 par le premier élément 44 n'est plus l'appui du pion 52 dans la rainure 56, mais l'appui de l'autre pion 58 dans le fond de la rainure 50.The rotation of the
Cet instant de l'inversion de configuration, correspondant au point P2 sur le graphe de la
La trajectoire 64 en arc de cercle du pion 58, centrée sur l'axe 48 au même titre que la trajectoire 62 du pion 52, présente un rayon supérieur à celui de cette dernière trajectoire, ce qui se traduit par une vitesse de translation accélérée du point d'attache 22, après son passage par le point P2. Cette vitesse est d'ailleurs de préférence sensiblement constante jusqu'à la fin de l'opération de fermeture schématisée sur la
Avec ce fonctionnement, la vitesse plus lente appliquée au démarrage de l'opération de fermeture permet de limiter l'usure mécanique des éléments se déplaçant relativement les uns par rapport aux autres, tandis que la vitesse plus rapide en fin de l'opération de fermeture permet de limiter l'usure électrique des contacts d'arcs 5a, 5b.With this operation, the slower speed applied at the start of the closing operation makes it possible to limit the mechanical wear of the elements moving relatively relative to one another, while the faster speed at the end of the closing operation. makes it possible to limit the electrical wear of the arcing

La rotation de l'arbre 32 s'effectue à présent dans le sens horaire. Dès le début de cette rotation, le premier élément 44 tourne dans le même sens, et entraîne le second élément 46 par l'appui du pion 52 dans la rainure 56. Dans le même temps, le pion 58 se déplace dans la rainure 50, en direction de son extrémité du sens antihoraire par rapport à l'axe 48. Ce déplacement du pion 58 dans la rainure 50 permet ici encore essentiellement de conserver une orientation sensiblement identique du second élément 46 dans son plan d'évolution durant son entraînement par le pion 52, afin de conserver une orientation sensiblement identique de la bielle 34. Cette dernière se déplace donc ici aussi uniquement selon son axe, en étant éventuellement sujet à de faibles oscillations angulaires autour du point d'attache 22.The rotation of the
Durant la phase initiale de l'opération d'ouverture, le déplacement du point d'attache 22, dans la direction 11 dans le sens opposé à celui des contacts fixes 4a, 5a, entraîne simultanément le corps secondaire 14 et le corps principal 9 via le ressort 16, comme cela est montré sur la
Cette inversion engendre une accélération de la vitesse linéaire de translation du point d'attache 22, qui sera maintenue sensiblement constante jusqu'à la position ouverte montrée sur la
Au moment suivant l'instant du changement de vitesse linéaire du point d'attache 22, le corps secondaire 14 est entraîné par ce point d'attache et le ressort 16 se comprime fortement, car le corps principal 9 est temporairement bloqué en translation par rapport au corps fixe 8, par des moyens de butée représentés schématiquement par l'élément 100. Cette spécificité est propre à la présente invention, et plusieurs conceptions possibles vont être détaillées ci-après.At the moment following the instant of the linear speed change of the
Le corps principal 9 reste donc un moment en position, sans être entraîné par le corps secondaire 14 qui continue sa course.The
Ainsi, cela conduit le ressort 16 à emmagasiner de l'énergie par déplacement du corps secondaire 14 relativement au corps principal 9 en direction d'une seconde position d'extrémité opposée à la première position d'extrémité susmentionnée. La
Après ce contact avec le fond 17 de l'alésage 12, les deux corps 9, 14 sont entraînés sensiblement à la même vitesse linéaire, jusqu'au point P6 du point d'attache 22. A cet instant, le corps principal s'arrête car il est en butée sur le corps fixe 8, et le corps secondaire 14 poursuit sa course jusqu'au point P7, correspondant à l'instant où le pion 52 arrive en appui dans le fond de la rainure 56, à son extrémité du sens antihoraire selon l'axe 48. Le sectionneur se trouve à cet instant à l'état ouvert, identique à celui représenté sur la
Il va à présent être décrit plusieurs exemples concrets de réalisation pour les moyens de butée 100, qui, pour rappel, contribuent à faire en sorte qu'au cours d'une opération d'ouverture, le ressort 16 puisse d'abord emmagasiner de l'énergie par déplacement du corps secondaire 14 relativement au corps principal 9 bloqué temporairement par ces moyens 100, puis libérer l'énergie emmagasinée pour provoquer une accélération du corps principal 9.Several concrete examples of embodiment will now be described for the abutment means 100, which, as a reminder, help to ensure that during an opening operation, the

Le corps principal 9 comporte quant à lui des fentes longitudinales 106 au niveau de sa partie située à l'opposé des contacts 4b, 5b, fentes dans lesquelles coulissent les extrémités des goupilles 102. Plus précisément, une goupille 102 est logée dans chaque fente 106, qui se décompose en deux parties de largeurs différentes, la partie 106b située la plus proche des contacts étant de largeur inférieure à l'autre partie 106a dans laquelle elle débouche, comme cela est le mieux visible sur la
Le corps secondaire 14 est équipé de moyens 110 de déverrouillage des moyens de butée, qui sont assimilables à des coulisseaux portés fixement par ce corps 14, et logés à coulissement dans les parties 106b des fentes 106 du corps principal. Chaque coulisseau 110 peut être chanfreiné afin d'adoucir son entrée en contact avec sa goupille associée.The

Ainsi, lors de l'initiation de la phase d'ouverture, les corps 9 et 14 se déplacent ensemble, avec pour conséquences le coulissement des coulisseaux 110 dans les parties 106b des fentes 106, et le coulissement des goupilles 102 dans les parties 106a de ces mêmes fentes. A partir d'un instant schématisé sur la
Sur cette même figure, il est montré que les coulisseaux 110 sont conçus pour libérer les moyens de butée après que le corps secondaire 14 ait été déplacé relativement au corps principal 9 selon une distance prédéterminée, au bout de laquelle ces coulisseaux viennent au contact des goupilles 102 et les repoussent radialement vers l'extérieur, en s'opposant à la force de rappel exercée sur ces mêmes goupilles. Le corps principal est alors libéré des goupilles qui s'enfoncent dans le corps fixe 8 sous l'effet des coulisseaux, et le ressort 16 se décomprime alors brusquement en produisant une accélération du corps principal 9 dont le fond d'alésage 17 vient se plaquer contre le corps secondaire 14, comme visible sur la
Ensuite, l'ouverture se poursuit de manière analogue à celle décrite précédemment, avec les goupilles 102 en appui glissant sur la surface extérieure du corps principal 9.Then, the opening continues in a similar manner to that described above, with the

Le corps secondaire 14 est équipé de moyens 210 de déverrouillage des moyens de butée, qui sont assimilables à des coulisseaux portés fixement par ce corps 14, et qui peuvent coulisser dans les parties 206b et 206a des fentes 206 de l'organe fixe 8a. Chaque coulisseau 210 peut être chanfreiné afin d'adoucir son entrée en contact avec sa goupille associée.The

Ainsi, lors de l'initiation de la phase d'ouverture, les corps 9 et 14 se déplacent ensemble, avec pour conséquences l'introduction et le coulissement des coulisseaux 210 dans les parties 206b des fentes 206, et le coulissement des goupilles 202 dans les parties 206a de ces mêmes fentes. A partir d'un instant schématisé sur la

L'organe fixe 8a est alors libéré des goupilles qui s'enfoncent dans le corps principal 8 sous l'effet des coulisseaux, et le ressort 16 se décomprime alors brusquement en produisant une accélération du corps principal 9 dont le fond d'alésage 17 ou un épaulement vient se plaquer contre le corps secondaire 14, comme visible sur la
Ensuite, l'ouverture se poursuit de manière analogue à celle décrite précédemment, avec les goupilles 202 en appui glissant sur la surface extérieure de l'organe fixe 8a, et les coulisseaux 210 coulissant dans les parties rétrécies 206a des fentes 206.Then, the opening continues in a similar manner to that described above, with the

De plus, le corps principal 9 présente, à son extrémité du côté opposé aux contacts 4b, 5b faisant partie intégrante des moyens de butée, des fentes longitudinales 306 dans lesquelles coulisse une extrémité du corps secondaire 14. Cette extrémité forme des moyens 210 de déverrouillage des moyens de butée, qui sont assimilables à des coulisseaux pouvant chacun être chanfreiné afin d'adoucir son entrée en contact avec la tulipe mécanique.In addition, the
Dans cet exemple, le ressort 16 n'est plus un ressort de compression, mais un ressort de traction. Il relie le fond 17 de l'alésage 12 au fond du corps secondaire 14. De plus, une tige 330 solidaire du fond 17 traverse un orifice du fond du corps secondaire 14, et se termine par une butée 332.In this example, the

Ainsi, lors de l'initiation de la phase d'ouverture, les corps 9 et 14 se déplacent ensemble via le ressort 16, avec pour conséquence un déplacement du corps 9 dans la tulipe 302.Thus, during the initiation of the opening phase, the

Ensuite, l'ouverture se poursuit de manière analogue à celle décrite précédemment, avec les rebords de la tulipe en appui glissant sur la surface extérieure du corps principal 9. L'ouverture est stoppée après que le corps principal ait été mis en butée à son extrémité contre le corps fixe 8, et que la butée de tige 332 ait été mise au contact du fond du corps secondaire 14, ce qui conduit à une mise en traction du ressort 16. Ainsi, dans ce dernier exemple, les contacts sont amenés en position ouverte de manière certaine, par le point d'attache 22, via la tige 330.Then, the opening continues in a similar manner to that described above, with the edges of the tulip sliding support on the outer surface of the
