Definitions
- the invention relates to current disconnectors comprising several electrical switches and in particular five-switch disconnectors used as phase inverters in a three-phase system, for example for pumping units where the alternator becomes the engine in order to obtain reversing the direction of rotation of the rotating machine.
- FIG. 1 very schematically shows such a disconnector phase inverter comprising five switches C1 to C5. He's plugged in between three phase inputs indicated respectively by A, B, C and three outputs of phases indicated respectively by A ', B', C '.
- Each switch comprises a first fixed contact 1 and a second contact 2 which cooperates with the first contact.
- the second contact 2 is movable to occupy a first position in which it is electrically connected to the fixed contact (see switches C2, C3, C4) and a second position according to which it is separated from the fixed contact (see switches C1 and C5).
- the movable contacts 2 of the switches C1 and C4 are electrically connected to the phase input C

- this disconnector for phase inverter is summarized in the table of FIG. 2.
- switches C1 and C5 are open (these switches being in the position indicated by O) and the switches C2 to C4 are closed (these switches being in the position indicated by F).
- phase input A is electrically connected to phase output A '
- the input of phase B is electrically connected to phase output B '
- phase input C is electrically connected to the phase output C '.
- switches C1 to C5 are all open. According to this position, the isolator inputs are all separate from its outputs.

- this disconnector is designed to pass from the position E1 to position E2 (or vice versa) necessarily passing through the position E0, other connection possibilities between inputs and outputs of the disconnector being prohibited.
- the object of the invention is to propose a switch arrangement for such a disconnector for phase inverter use in which the switches are controlled by a single command while avoiding connection possibilities prohibited.
- this problem is solved using a switch electric comprising a first fixed contact and a second cooperating with the fixed contact, this second contact being movable to occupy a first position according to which it is connected to the fixed contact and a second position according to which it is separate from the fixed contact, characterized in that the second contact is arranged to move between its first position and its second position by a movement in translation in a longitudinal direction and in that the displacement of the second contact is ensured by the play of a pair of levers articulated together in rotation and comprising a first lever, one of which end is connected to the second contact via an axis of rotation movable in translation in said longitudinal direction and a second lever, one end is rotatably mounted on a fixed axis relative to the first contact.
- such a switch arrangement allows to design a disconnector with five switches functioning as phase reverser with a single three-position control and a system connecting rod connecting the second levers of the switches to the control, by a judicious choice of the ratio between the linkage kinematics and the kinematics internal electrical switches.

- Figure 5 shows the disconnector of Figure 3 in a third position corresponding to position E2 of the table in FIG. 2.
- FIG 3 shows schematically five switches C1 to C5 according to the invention which are part of a so-called pentapole disconnector serving as phase inverter, similar to that shown in Figure 1, the inputs and the outputs corresponding to phases A to C and A 'to C' are however not represented.
- Each switch such as C1 includes a fixed contact 1 and a contact 2 which is movable to occupy a first position according to which it is connected to fixed contact 1 (closing position F of the switch) and a second position according to which it is separated from fixed contact 1 (opening position O of the switch).
- the movable contact 2 moves between these two positions by a translational movement in a longitudinal direction of movement indicated by 3.
- the translational movement in the direction 3 of the movable contact 2 is ensured by the play of a pair of levers L1 and L2. More specifically, the lever L1 has one end which is connected to contact 2 via an axis A1 of rotation mobile in translation in the longitudinal direction 3. The levers L1 and L2 are hinged together in rotation about an axis A2. The lever L2 has one end which is rotatably mounted on an axis A3 fixed relative to the contact 1.
- the relative angular displacement between the levers L1 and L2 is transformed in a translational movement of the movable contact 2, the choice of the length levers L1 and L2 and the relative angular displacement between these two levers for adjusting the stroke of the movable contact.
- a disconnector according to the invention with five switches electrics used as phase inverter includes a single control three-position rickshaw 4 mechanically connected to the switches by through a linkage system 5.
- the three-position control 4 is here an electric motor whose rotor A4 serves as a movement transmission device for the linkage system.
- the connecting rod system 5 comprises, for each switch C1, C2, C4 and C5, a lever L3 integral in rotation with the lever L2 of each switch and for the switch C3 a lever L4 integral in rotation with the lever L2 of this switch.
- the operation of the linkage system 5 is as follows.
- lever L6 moves in translation the control rod L5 to which it is connected.
- the displacement of this lever L5 is transformed into an angular displacement of the lever L3 associated with the switch C5.
- the translational movement of this connecting rod command L5 causes the translational movement of the control rod L5 associated with switch C4, causing the translational movement of the movable contact 2 of this switch C4, and so on for the others switches C3 to C1.
- the displacement in translation of the connecting rods command L5 is transformed by the levers L3 and L4 in a displacement angle of levers L1 and L2 of each switch C1 to C5 which in turn transforms the moving contacts 2 into translation switches C1 to C5.
- Obtaining positions E1, E0, E2 of the disconnector in accordance with table in Figure 2 is based on the ratio of the linkage kinematics and the internal kinematics of the switches, the lengths of the control rods L5 having no influence on the operation of the disconnector.
- the disconnector is shown in its position E0 in the table of the Figure 2. In this position, we see that all the movable contacts 2 of switches are separated from the fixed contacts 1.
- the levers L3 and L4 are here parallel to each other.
- the switches C1 and C5 have their levers L1 and L2 which occupy a first identical angular position.
- the levers L1 and L2 of switches C2 and C4 occupy a second identical angular position.
- the levers L1 and L2 of switch C3 occupy a third angular position intermediate to the first and second angular positions above.
- the kinematics of the levers L1 and L2 of the switch C3 is different from that of levers L1 and L2 of the switches C1, C2 and C4, C5. Furthermore, the angular position of the levers L1 and L2 of the switch C1 is symmetrical, in direction 3, at the angular position of levers L1 and L2 of switch C2.
- the lever L6 has rotated in a first direction of rotation of 90 ° relative to its position in Figure 4.
- the levers L1 and L2 of the switches C1 and C5 now occupy said second angular position so that these switches are open.
- the L2 levers of these switches have turned counterclockwise by an angle a.
- the levers L2 of the switches C2 and C4 have rotated counterclockwise by an angle a so these switches are also in a closed position.
- the L2 lever of switch C3 has rotated counterclockwise by a larger angle ⁇ that a (because the length of the lever L4 is less than the length of the levers L3) so that this switch is in the closed position.
- the lever L6 has rotated in a second direction of rotation of 90 ° relative to its position in Figure 4.
- the levers L1 and L2 of the switches C2 and C4 now occupy said first angular position and these switches are open.
- the L2 levers of these switches have therefore turned clockwise at an angle a.
- the levers L2 of switches C1 and C5 have turned clockwise by an angle a so these switches are in closed position.
- the lever L2 of the switch C3 has turned in the direction time of an angle ⁇ so that this switch is also in a position of closing.
- the transition from position E0 to the position E1 of the disconnector is obtained by a first 90 ° rotation of the rotor of command 4 and the transition from position E0 to position E2 is obtained by a second 90 ° rotation of the rotor of control 4 but in the direction reverse at the first rotation.
- the angle of rotation of the rotor A4 may be different 90 ° (for example 30 °) but an angle of 90 ° ensures no reversibility of the transmission of the command on the move.
- the length of the rod L6 is chosen according to the power of control 4 and the effort required to move the movable contacts 2.
- linkage system 5 can be replaced by a gear system or a cable system.

Description
L'invention concerne les sectionneurs de courant comprenant plusieurs commutateurs électriques et notamment les sectionneurs à cinq commutateurs utilisés comme inverseurs de phases dans un système triphasé, par exemple pour des groupes de pompage où l'alternateur devient moteur afin d'obtenir l'inversion du sens de rotation de la machine tournante.The invention relates to current disconnectors comprising several electrical switches and in particular five-switch disconnectors used as phase inverters in a three-phase system, for example for pumping units where the alternator becomes the engine in order to obtain reversing the direction of rotation of the rotating machine.
La figure 1 montre de façon très schématique un tel sectionneur
inverseur de phases comportant cinq commutateurs C1 à C5. Il est branché
entre trois entrées de phases indiquées respectivement par A,B,C et trois sorties
de phases indiquées respectivement par A',B',C'. Chaque commutateur
comprend un premier contact fixe 1 et un second contact 2 qui coopère avec le
premier contact. Le second contact 2 est mobile pour occuper une première
position selon lequel il est relié électriquement au contact fixe (voir les
commutateurs C2,C3,C4) et une seconde position selon laquelle il est séparé du
contact fixe (voir les commutateurs C1 et C5).Figure 1 very schematically shows such a disconnector
phase inverter comprising five switches C1 to C5. He's plugged in
between three phase inputs indicated respectively by A, B, C and three outputs
of phases indicated respectively by A ', B', C '. Each switch
comprises a first fixed
Comme visible sur la figure 1, les contacts mobiles 2 des commutateurs
C1 et C4 sont reliés électriquement à l'entrée de phase C, les contacts mobiles 2
des commutateurs C2 et C5 sont reliés électriquement à l'entrée de phase A et
le contact mobile 2 du commutateur C3 est relié à l'entrée de phase B. Par
ailleurs, les contacts fixes 1 des commutateurs C1 et C2 sont reliés
électriquement à la sortie de phase A', les contacts fixes 1 des commutateurs C4
et C5 sont reliés électriquement à la sortie de phase C' et le contact fixe 1 du
commutateur C3 est relié électriquement à la sortie de phase B'.As seen in Figure 1, the
Le fonctionnement de ce sectionneur à usage d'inverseur de phases est résumé dans le tableau de la figure 2. Selon une première position E1 du sectionneur, les commutateurs C1 et C5 sont ouverts (ces commutateurs étant dans la position indiquée par O) et les commutateurs C2 à C4 sont fermés (ces commutateurs étant dans la position indiquée par F). Selon cette position, l'entrée de phase A est reliée électriquement à la sortie de phase A', l'entrée de phase B est reliée électriquement à la sortie de phase B' et l'entrée de phase C est reliée électriquement à la sortie de phase C'. Selon une seconde position E0 du sectionneur, les commutateurs C1 à C5 sont tous ouverts. Selon cette position, les entrées du sectionneur sont toutes séparées de ses sorties. Selon enfin une troisième position E2 du sectionneur, les commutateurs C1,C3 et C5 sont fermés et les commutateurs C2 et C4 sont ouverts. Selon cette position, l'entrée de phase C est reliée électriquement à la sortie de phase A', l'entrée de phase B est reliée électriquement à la sortie de phase B' et l'entrée de phase A est reliée électriquement à la sortie de phase C'. Il en résulte une inversion des phases A et C en sortie du sectionneur par rapport à la position El du sectionneur.The operation of this disconnector for phase inverter is summarized in the table of FIG. 2. According to a first position E1 of the disconnector, switches C1 and C5 are open (these switches being in the position indicated by O) and the switches C2 to C4 are closed (these switches being in the position indicated by F). According to this position, phase input A is electrically connected to phase output A ', the input of phase B is electrically connected to phase output B 'and phase input C is electrically connected to the phase output C '. According to a second position E0 of the disconnector, switches C1 to C5 are all open. According to this position, the isolator inputs are all separate from its outputs. According to finally a third position E2 of the disconnector, switches C1, C3 and C5 are closed and switches C2 and C4 are open. According to this position, phase input C is electrically connected to phase output A ', the input of phase B is electrically connected to phase output B 'and phase input A is electrically connected to the phase output C '. This results in an inversion of the phases A and C at the output of the disconnector relative to the position El of disconnector.
D'une façon générale, ce sectionneur est prévu pour passer de la position E1 à la position E2 (ou inversement) en passant nécessairement par la position E0, les autres possibilités de connexion entre les entrées et les sorties du sectionneur étant interdites.In general, this disconnector is designed to pass from the position E1 to position E2 (or vice versa) necessarily passing through the position E0, other connection possibilities between inputs and outputs of the disconnector being prohibited.
Le but de l'invention est de proposer un agencement de commutateur pour un tel sectionneur à usage d'inverseur de phases dans lequel les commutateurs sont commandés par une commande unique tout en évitant les possibilités de connexion interdites.The object of the invention is to propose a switch arrangement for such a disconnector for phase inverter use in which the switches are controlled by a single command while avoiding connection possibilities prohibited.
Selon l'invention, ce problème est résolu à l'aide d'un commutateur électrique comprenant un premier contact fixe et un second coopérant avec le contact fixe, ce second contact étant mobile pour occuper une première position selon laquelle il est relié au contact fixe et une seconde position selon laquelle il est séparé du contact fixe, caractérisé en ce que le second contact est agencé pour se déplacer entre sa première position et sa seconde position par un mouvement en translation selon une direction longitudinale et en ce que le déplacement du second contact est assuré par le jeu d'une paire de leviers articulés entre eux en rotation et comprenant un premier levier dont une extrémité est reliée au second contact par l'intermédiaire d'un axe de rotation mobile en translation selon ladite direction longitudinale et un second levier dont une extrémité est montée à rotation sur un axe fixe par rapport au premier contact.According to the invention, this problem is solved using a switch electric comprising a first fixed contact and a second cooperating with the fixed contact, this second contact being movable to occupy a first position according to which it is connected to the fixed contact and a second position according to which it is separate from the fixed contact, characterized in that the second contact is arranged to move between its first position and its second position by a movement in translation in a longitudinal direction and in that the displacement of the second contact is ensured by the play of a pair of levers articulated together in rotation and comprising a first lever, one of which end is connected to the second contact via an axis of rotation movable in translation in said longitudinal direction and a second lever, one end is rotatably mounted on a fixed axis relative to the first contact.
Comme cela apparaítra par la suite, un tel agencement de commutateur permet de concevoir un sectionneur à cinq commutateurs fonctionnant comme inverseur de phases avec une seule commande à trois positions et un système d'embiellage reliant les seconds leviers des commutateurs à la commande, par un choix judicieux du rapport entre la cinématique d'embiellage et la cinématique interne des commutateurs électriques.As will appear later, such a switch arrangement allows to design a disconnector with five switches functioning as phase reverser with a single three-position control and a system connecting rod connecting the second levers of the switches to the control, by a judicious choice of the ratio between the linkage kinematics and the kinematics internal electrical switches.
D'autres caractéristiques et avantages apparaítront encore mieux à la lecture de la description qui suit d'un exemple de réalisation de l'invention en relation avec les dessins. Other characteristics and advantages will appear even better on reading of the description which follows of an exemplary embodiment of the invention in relationship with the drawings.
La figure 1 est une représentation très schématique d'un sectionneur comportant cinq commutateurs et servant comme inverseur de phases.Figure 1 is a very schematic representation of a disconnector comprising five switches and serving as a phase inverter.
La figure 2 résume sous la forme d'un tableau, le fonctionnement d'un tel sectionneur inverseur de phases.Figure 2 summarizes in the form of a table, the operation of such phase reversing disconnector.
La figure 3 montre de manière schématique un sectionneur à cinq commutateurs selon l'invention dans une première position correspondant à la position E1 du tableau de la figure 2.Figure 3 shows schematically a disconnector with five switches according to the invention in a first position corresponding to the position E1 of the table in FIG. 2.
La figure 4 montre le sectionneur de la figure 3 dans une seconde position correspondant à la position E0 du tableau de la figure 2.Figure 4 shows the disconnector of Figure 3 in a second position corresponding to position E0 of the table in FIG. 2.
La figure 5 montre le sectionneur de la figure 3 dans une troisième position correspondant à la position E2 du tableau de la figure 2.Figure 5 shows the disconnector of Figure 3 in a third position corresponding to position E2 of the table in FIG. 2.
La figure 3 montre de façon schématique cinq commutateurs C1 à C5 selon l'invention qui font partie d'un sectionneur dit pentapolaire servant comme inverseur de phases, analogue à celui montré sur la figure 1, les entrées et les sorties correspondant aux phases A à C et A' à C' n'étant toutefois pas représentées.Figure 3 shows schematically five switches C1 to C5 according to the invention which are part of a so-called pentapole disconnector serving as phase inverter, similar to that shown in Figure 1, the inputs and the outputs corresponding to phases A to C and A 'to C' are however not represented.
Chaque commutateur tel que C1 comprend un contact 1 fixe et un
contact 2 qui est mobile pour occuper une première position selon laquelle il est
relié au contact fixe 1 (position de fermeture F du commutateur) et une seconde
position selon laquelle il est séparé du contact fixe 1 (position d'ouverture O du
commutateur).Each switch such as C1 includes a
Le contact mobile 2 se déplace entre ces deux positions par un
mouvement en translation suivant une direction de déplacement longitudinale
indiquée par 3.The
Le déplacement en translation suivant la direction 3 du contact mobile 2
est assuré par le jeu d'une paire de leviers L1 et L2. Plus particulièrement, le
levier L1 a une extrémité qui est reliée au contact 2 par l'intermédiaire d'un axe
A1 de rotation mobile en translation selon la direction longitudinale 3. Les leviers
L1 et L2 sont articulés entre eux en rotation autour d'un axe A2. Le levier L2 a
une extrémité qui est montée à rotation sur un axe A3 fixe par rapport au contact
1. Ainsi, le déplacement angulaire relatif entre les leviers L1 et L2 est transformé
en un déplacement en translation du contact mobile 2, le choix de la longueur
des leviers L1 et L2 et du déplacement angulaire relatif entre ces deux leviers
permettant de régler la course du contact mobile.The translational movement in the
Figures 3 à 5, un sectionneur selon l'invention à cinq commutateurs
électriques servant d'inverseur de phases comprend une commande unique à
tire-pousse à trois positions 4 reliée mécaniquement aux commutateurs par
l'intermédiaire d'un système d'embiellage 5.Figures 3 to 5, a disconnector according to the invention with five switches
electrics used as phase inverter includes a single control
three-
La commande à trois positions 4 est ici un moteur électrique dont le rotor
A4 sert d'organe de transmission de mouvement au système d'embiellage.The three-
Le système d'embiellage 5 comprend, pour chaque commutateur
C1,C2,C4 et C5, un levier L3 solidaire en rotation du levier L2 de chaque
commutateur et pour le commutateur C3 un levier L4 solidaire en rotation du
levier L2 de ce commutateur.The
Il comprend encore un ensemble de bielles de commande L5 articulées
en rotation les unes à la suite des autres et aux leviers L3 et L4. Une de ces
bielles L5 est reliée à la commande 4 par l'intermédiaire d'un levier L6 solidaire
du rotor A4 de la commande 4.It also includes a set of articulated L5 control rods
in rotation one after the other and to the levers L3 and L4. One of these
connecting rods L5 is connected to
Le fonctionnement du système d'embiellage 5 est le suivant. Quand le
rotor A4 de la commande 4 tourne d'un certain angle, le levier L6 déplace en
translation la bielle de commande L5 à laquelle il est relié. Le déplacement de ce
levier L5 est transformé en un déplacement angulaire du levier L3 associé au
commutateur C5. Il en résulte un déplacement angulaire du levier L2 solidaire de
ce levier L3 et donc un déplacement en translation du contact mobile 2 du
commutateur C5. Par ailleurs, le déplacement en translation de cette bielle de
commande L5 provoque le déplacement en translation de la bielle de commande
L5 associée au commutateur C4, entraínant le déplacement en translation du
contact mobile 2 de ce commutateur C4, et ainsi de suite pour les autres
commutateurs C3 à C1. Ainsi, le déplacement en translation des bielles de
commande L5 est transformé par les leviers L3 et L4 en un déplacement
angulaire des leviers L1 et L2 de chaque commutateur C1 à C5 qui se
transforme à son tour en un déplacement en translation des contacts mobiles 2
des commutateurs C1 à C5.The operation of the
L'obtention des positions E1,E0,E2 du sectionneur conformément au tableau de la figure 2 repose sur le rapport de la cinématique d'embiellage et la cinématique interne des commutateurs, les longueurs des bielles de commande L5 n'ayant pas d'influence sur le fonctionnement du sectionneur.Obtaining positions E1, E0, E2 of the disconnector in accordance with table in Figure 2 is based on the ratio of the linkage kinematics and the internal kinematics of the switches, the lengths of the control rods L5 having no influence on the operation of the disconnector.
Plus particulièrement, pour réaliser la succession des positions fermées et ouvertes, d'une part des commutateurs C1, C2, C4, et C5, et d'autre part, du commutateur C3, les leviers L1 et L2 ce chaque commutateur étant identiques, il faut que, lors d'un changement de position du sectionneur, par exemple lors du changement de la position E1 à la position E0, le levier L2 des commutateurs C1, C2, C4 et C5 tourne d'un angle a et que le levier L2 du commutateur C3 tourne simultanément d'un angle β tel que β vérifie la relation 3α = 2β. Ceci est obtenu simplement par une construction des leviers L3 et L4 telle que la longueur I du levier L4 et la longueur L d'un levier L3 vérifient la relation suivante : L*sinus(α) = I*sinus(β), c'est-à-dire que L est supérieure à 1.More specifically, to carry out the succession of closed positions and open, on the one hand switches C1, C2, C4, and C5, and on the other hand, switch C3, the levers L1 and L2 this each switch being identical, it when changing the position of the disconnector, for example when change from position E1 to position E0, lever L2 of switches C1, C2, C4 and C5 turns by an angle a and that the lever L2 of the switch C3 rotates simultaneously by an angle β such that β satisfies the relation 3α = 2β. this is obtained simply by a construction of the levers L3 and L4 such that the length I of lever L4 and length L of lever L3 verify the relationship following: L * sine (α) = I * sine (β), i.e. L is greater than 1.
Figure 4, le sectionneur est montré dans sa position E0 du tableau de la
figure 2. Dans cette position, on voit que tous les contacts mobiles 2 des
commutateurs sont séparés des contacts fixes 1. Les leviers L3 et L4 sont ici
parallèles entre eux. Les commutateurs C1 et C5 ont leurs leviers L1 et L2 qui
occupent une première position angulaire identique. Les leviers L1 et L2 des
commutateurs C2 et C4 occupent une seconde position angulaire identique. Les
leviers L1 et L2 du commutateur C3 occupent une troisième position angulaire
intermédiaire par rapport aux première et seconde positions angulaires ci-dessus.
Comme visible sur cette figure, la cinématique des leviers L1 et L2 du
commutateur C3 est différente de celle des leviers L1 et L2 des commutateurs
C1,C2 et C4,C5. Par ailleurs, la position angulaire des leviers L1 et L2 du
commutateur C1 est symétrique, suivant la direction 3, à la position angulaire des
leviers L1 et L2 du commutateur C2.Figure 4, the disconnector is shown in its position E0 in the table of the
Figure 2. In this position, we see that all the
Figure 3, le levier L6 a tourné selon un premier sens de rotation de 90° par rapport à sa position sur la figure 4. Les leviers L1 et L2 des commutateurs C1 et C5 occupent maintenant ladite seconde position angulaire de sorte que ces commutateurs sont ouverts. Les leviers L2 de ces commutateurs ont tourné dans le sens horaire inverse d'un angle a. Les leviers L2 des commutateurs C2 et C4 ont tourné dans le sens horaire inverse d'un angle a de sorte que ces commutateurs sont aussi dans une position de fermeture. Le levier L2 du commutateur C3 a tourné dans le sens horaire inverse d'un angle β plus grand que a (du fait que la longueur du levier L4 est inférieure à la longueur des leviers L3) de sorte que ce commutateur est en position de fermeture.Figure 3, the lever L6 has rotated in a first direction of rotation of 90 ° relative to its position in Figure 4. The levers L1 and L2 of the switches C1 and C5 now occupy said second angular position so that these switches are open. The L2 levers of these switches have turned counterclockwise by an angle a. The levers L2 of the switches C2 and C4 have rotated counterclockwise by an angle a so these switches are also in a closed position. The L2 lever of switch C3 has rotated counterclockwise by a larger angle β that a (because the length of the lever L4 is less than the length of the levers L3) so that this switch is in the closed position.
Figure 5, le levier L6 a tourné selon un second sens de rotation de 90° par rapport à sa position sur la figure 4. Les leviers L1 et L2 des commutateurs C2 et C4 occupent maintenant ladite première position angulaire et ces commutateurs sont ouverts. Les leviers L2 de ces commutateurs ont donc tourné dans le sens horaire d'un angle a. Les leviers L2 des commutateurs C1 et C5 ont tourné dans le sens horaire d'un angle a de sorte que ces commutateurs sont en position de fermeture. Le levier L2 du commutateur C3 a tourné dans le sens horaire d'un angle β de sorte que ce commutateur est aussi dans une position de fermeture.Figure 5, the lever L6 has rotated in a second direction of rotation of 90 ° relative to its position in Figure 4. The levers L1 and L2 of the switches C2 and C4 now occupy said first angular position and these switches are open. The L2 levers of these switches have therefore turned clockwise at an angle a. The levers L2 of switches C1 and C5 have turned clockwise by an angle a so these switches are in closed position. The lever L2 of the switch C3 has turned in the direction time of an angle β so that this switch is also in a position of closing.
Ainsi que cela ressort des figures 3 à 5, le passage de la position E0 à la
position E1 du sectionneur est obtenu par une première rotation de 90° du rotor
de la commande 4 et le passage de la position E0 à la position E2 est obtenu par
une seconde rotation de 90° du rotor de la commande 4 mais dans le sens
inverse à la première rotation. L'angle de rotation du rotor A4 peut être différent
de 90° (par exemple de 30°) mais un angle de 90° permet de garantir une non
réversibilité de la transmission de la commande en déplacement. La longueur de
la bielle L6 est choisie en fonction de la puissance de la commande 4 et de
l'effort à fournir pour déplacer les contacts mobiles 2.As shown in Figures 3 to 5, the transition from position E0 to the
