Description
La présente invention concerne un interrupteur auto-sectionneur à moyenne tension, utilisable jusqu'à 36 kV, avec extensions possibles jusqu'à 72 kV. Cet appareil trouve application dans la réalisation de cellules et postes à moyenne tension, intérieurs ou extérieurs.The present invention relates to a self-isolating switch at medium voltage, usable up to 36 kV, with possible extensions up to 72 kV. This device finds application in the realization of cells and substations medium voltage, indoor or outdoor.
On appelle interrupteur auto-sectionneur un appareil électrique ayant le pouvoir de couper une intensité nominale, le plus souvent 400, 630 ou 1250 ampères et qui, lorsqu'il est en position ouverte, présente entre ses bornes une excellente tenue diélectrique, au moins égale à celle qui est exigée pour les sectionneurs.We call an auto-disconnector switch a device electric having the power to cut an intensity nominal, most often 400, 630 or 1250 amps and which, when in the open position, present between its terminals excellent dielectric strength, at least equal to that which is required for disconnectors.
L'interrupteur auto-sectionneur de l'invention est dérivé du disjoncteur auto-sectionneur ayant fait l'objet de la demande de brevet européen EP-A-0 543 681 dont le principe est rappelé maintenant.The self-disconnecting switch of the invention is derived from the self-isolating circuit breaker that was the subject of European patent application EP-A-0 543 681, the principle is recalled now.
Un tel disjoncteur auto-sectionneur comprend, pour chaque pôle, un traversée isolante enfermant une ampoule à vide, la traversée comprenant à une première extrémité un premier contact relié à une première borne de l'ampoule à vide et à une seconde extrémité un second contact relié à une seconde borne de l'ampoule à vide, les traversées étant fixées à un profilé métallique le long duquel est disposé un arbre de manoeuvre commun aux ampoules à vide et actionné par une commande de manoeuvre des ampoules à vide contenu dans un coffret solidaire du profilé, ce dernier étant actionné en rotation pour assurer la fonction sectionnement.Such a self-disconnecting circuit breaker includes, for each pole, an insulating bushing enclosing a light bulb empty, the crossing comprising at a first end a first contact connected to a first terminal of the light bulb empty and at a second end a second contact connected to a second terminal of the vacuum interrupter, the bushings being fixed to a metal profile along which is disposed a operating shaft common to vacuum interrupters and operated by a command to operate the vacuum bulbs contained in a box integral with the profile, the latter being actuated in rotation to ensure the sectioning function.
Un tel disjoncteur auto-sectionneur permet de remplir les fonctions de coupure du courant et de sectionnement, et, de ce fait, il est équivalent à un disjoncteur encadré par deux sectionneurs. Sa construction est économique, son encombrement réduit, sa maintenance est facilitée par le fait qu'en position de sectionnement, les pôles se trouvent logés dans un tiroir extractible sous tension en toute sécurité. Such a self-disconnecting circuit breaker allows filling the current cut and disconnect functions, and, therefore, it is equivalent to a circuit breaker framed by two disconnectors. Its construction is economical, its reduced dimensions, its maintenance is facilitated by the causes the poles to be in the sectioning position housed in an extractable drawer under full tension security.
L'interrupteur auto-sectionneur de l'invention repose sur deux principes importants:
- l'utilisation d'une ampoule à vide de performances réduites, donc de prix de revient relativement faible,
- la combinaison des mouvements de coupure par l'ampoule et d'isolement par la rotation des pôles.
- the use of a vacuum bulb of reduced performance, therefore of relatively low cost price,
- the combination of cutting movements by the bulb and isolation by rotation of the poles.
L'invention a pour objet un interrupteur auto-sectionneur triphasé caractérisé en ce qu'il comprend trois traversées isolantes contenant chacune une ampoule à vide, les traversées étant solidaires d'une poutre pouvant pivoter à l'intérieur d'un chassis, les ampoules à vide étant manoeuvrées par l'intermédiaire d'un arbre de commande associé à un mécanisme de manoeuvre, la poutre étant solidaire d'un organe de mise en rotation par ressort à passage de point mort, l'ouverture de l'interrupteur se faisant par la manoeuvre successive de l'arbre de commande et de l'organe de mise en rotation de la poutre.The subject of the invention is a self-isolating switch three-phase characterized in that it comprises three insulating bushings each containing a vacuum interrupter, the crossings being integral with a beam which can pivot inside a chassis, the vacuum bulbs being operated by a control shaft associated with an operating mechanism, the beam being secured to a spring-rotating member shift from neutral, the switch opens by the successive operation of the control shaft and of the member for rotating the beam.
Selon un premier mode de réalisation de l'invention, l'arbre de commande est du type tire-pousse, le mécanisme de manoeuvre comprenant un électro-aimant.According to a first embodiment of the invention, the drive shaft is of the rickshaw type, the operation comprising an electromagnet.
Selon un deuxième mode de réalisation de l'invention, l'arbre de commande est un arbre rotatif, le mécanisme de manoeuvre comprenant un électro-aimant.According to a second embodiment of the invention, the control shaft is a rotary shaft, the mechanism operation comprising an electromagnet.
Dans tous les cas, l'électro-aimant est alimenté jusqu'au passage par le point mort de l'organe de mise en rotation à passage de point mort.In all cases, the electromagnet is supplied until passing through the neutral point of the setting member rotation at neutral.
L'invention est expliquée en détail par la description de deux exemples de réalisation, en référence au dessin annexé dans lequel:
- la figure 1 représente, en perspective, un interrupteur auto-sectionneur selon un premier mode de mise en oeuvre de l'invention, dans lequel la manoeuvre des pôles est assurée par un système de type "tire-pousse",
- la figure 2 est une vue partielle en élévation de l'interrupteur auto-sectionneur de la Fig. 1, montrant notamment le système "tire-pousse",
- la figure 3 est une vue de face de l'interrupteur auto-sectionneur de la Fig. 1,
- la figure 4 est une vue en perspective d'un interrupteur auto-sectionneur selon un second mode de mise en oeuvre de l'invention, dans lequel la manoeuvre des pôles est assurée par un système de type rotatif,
- la figure 5 est une vue de face de l'interrupteur de la figure 4.
- FIG. 1 represents, in perspective, a self-disconnecting switch according to a first embodiment of the invention, in which the operation of the poles is ensured by a system of the "pull-pull" type,
- FIG. 2 is a partial view in elevation of the auto-disconnector switch of FIG. 1, showing in particular the "rickshaw" system,
- FIG. 3 is a front view of the auto-disconnector switch of FIG. 1,
- FIG. 4 is a perspective view of a self-disconnecting switch according to a second embodiment of the invention, in which the operation of the poles is ensured by a system of the rotary type,
- FIG. 5 is a front view of the switch in FIG. 4.
Dans la figure 1, la référence 1 désigne un châssis
tubulaire, muni de roulettes 2, destiné à être placé, à la
manière d'un tiroir extractible, dans une armoire non
représentée.In Figure 1,
Une poutre horizontale 4 est articulée par ses deux
extrémités 4A et 4B à des plaques 5A et 5B fixées au
châssis, de manière à pouvoir effectuer un mouvement de
rotation de 90° autour de son axe longitudinal. La poutre 4
est au potentiel de la terre.A
A la poutre 4 sont fixées trois traversées isolantes 7A, 7B et 7C, contenant chacune une ampoule à vide. Chacune de ces traversée constitue un pôle de l'interrupteur. Pour la clarté du dessin, la traversée 7C n'a été représentée que partiellement et en traits tiretés; seule l'ampoule 9B de la traversée 7B a été représentée. Selon une caractéristique de l'invention, l'ampoule à vide est choisie, parmi les ampoules du commerce fabriquées économiquement en grande série, en fonction de son aptitude à couper le courant nominal du dispositif dans lequel l'interrupteur est installé, sans se préoccuper de la tenue en tension entre les bornes de l'ampoule. Cette tension est nulle lorsque l'ampoule a ses contacts en position fermée. La tenue en tension est assurée par le pivotement des pôles, comme il sera expliqué plus loin. A titre d'exemple, on choisira, pour couper 400 ou 630 ampères sous la tension simple correspondant à un réseau 24 kV, on choisira la moins chère et la plus petite des ampoules utilisées habituellement:
- pour un recloser 11 kV ou,
- pour un
contacteur 7,2 kV ou 3,3 kV ou 1 kV.
- for a recloser 11 kV or,
- for a 7.2 kV or 3.3 kV or 1 kV contactor.
A l'abri de la poutre 4 est disposé un arbre 10 de
commande d'ouverture et de fermeture des pôles, qui peut
être actionné par rotation ou par translation.Sheltered from
Dans l'exemple de la figure 1, cet arbre 10 est un
arbre du type "tire-pousse", puisqu'il agit en se déplaçant
en translation le long de son propre axe, sous l'action
d'une bobine d'électro-aimant 12; le mécanisme de commande
des pôles est expliqué en référence au pôle 7B: la tige
mobile 12B de l'ampoule à vide 9B est reliée à une première
extrémité d'une bielle métallique 13B articulée autour d'un
axe 14B solidaire de la traversée 7B; la seconde extrémité
de la bielle 13B est articulée à une première extrémité
d'une bielle isolante 15B susceptible de tenir la tension de
fonctionnement de l'appareil; la seconde extrémité de la
bielle isolante 15B est articulée dans une lumière 17B d'une
première extrémité d'une équerre métallique 18B dont la
seconde extrémité 19B est articulée sur l'arbre de commande
10. L'équerre 18B pivote autour d'un axe 20B solidarisé à la
poutre 4. Le déplacement en translation le long de son axe
de l'arbre 10 provoque la rotation de l'équerre 18B et ce
mouvement est communiqué à la tige de commande 12B par les
bielles 15B et 13B.In the example of FIG. 1, this
Pour permettre le débattement nécessaire vers le haut
de l'arbre 10, il est muni, de part et d'autre des pôles
d'articulations 22 et 23 appropriées. On note que l'arbre 10
a de préférence une section rectangulaire dans sa partie
comprise entre les articulations, pour permettre la fixation
aisée des équerres; de part et d'autre de ces articulations
il a de préférence une forme circulaire, pour coulisser
librement à travers les plaques 5A et 5B.To allow the necessary upward travel
of the
On notera que l'arbre de commande 10 de manoeuvre des
ampoules est logé à l'intérieur des articulations de la
poutre 4, l'arbre 10 se déplaçant en translation tout à fait
indépendemment du mouvement de rotation de la poutre 4. It will be noted that the
Le pôle 7B possède une première prise de courant 24B
coopérant avec une arrivée de courant 25B, et une seconde
prise de courant 26B coopèrant avec une barre 27B. Les autre
pôles possèdent les mêmes prises coopérant avec les mêmes
éléments homologues. Des capots isolants tels que 29C
assurent une isolation entre les pôles.The
Le fonctionnement de l'interrupteur est le suivant.The operation of the switch is as follows.
Le pôle est dans la configuration de la Fig.1The pole is in the configuration of Fig. 1
La bobine de l'électro-aimant 12 est excité, ce qui a
pour effet de déplacer l'arbre 10 en translation, provoquant
l'ouverture des ampoules à vide. Immédiatement, ou après un
délai déterminé, on provoque le pivotement brusque à 90° de
la poutre 4, ce qui entraíne le sectionnement des pôles. Dès
que le passage par le point mort est effectué, au plus tard
lorsque le sectionnement est achevé, on cesse l'alimentation
de l'éléctro-aimant; sous l'effet de la pression
atmosphérique, les ampoules à vide se referment.The coil of the
Il suffit de provoquer la rotation de la poutre 4 de
90°, dans le sens opposé à celui de l'ouverture. En
variante, la fermeture peut être effectuée par rotation de
la poutre, les contacts de l'ampoule à vide restant ouverts.
Le courant dans le circuit principal est alors établi à la
fin de la rotation en fermant les contacts de l'ampoule à
vide.It is enough to cause the rotation of the
On décrit maintenant, en référence aux Fig. 1 à 3, le
mécanisme permettant de provoquer la rotation brusque de la
poutre 4.We will now describe, with reference to FIGS. 1 to 3, the
mechanism for causing the sudden rotation of the
Une came 30 est solidarisée à la poutre 4 par une tube
31 traversant la plaque 5A dans laquelle il peut pivoter
librement; on note qu'à l'intérieur de ce tube passe l'arbre
10 de manoeuvre des pôles. On désigne par O la trace de
l'axe de rotation de la came 30.A
La came 30 est articulée à une première extrémité A
d'un ressort 30A qui est maintenu comprimé lorsque
l'interrupteur est en position fermée. La seconde extrémité
B du ressort 30A est fixée à la plaque 5A. Lorsque
l'interrupteur est en position fermée, le ressort pousse la
came dans le sens tendant à la faire pivoter en sens inverse
des aiguilles d'une montre. L'angle entre l'axe AB du
ressort 30A et la ligne AO est légèrement inférieur à 180
degrés d'angle.
La came est maitenue immobile par un ergot 32 fixé à
un écrou 33 déplaçable en translation sur une tige filetée
34 pouvant être entraínée en rotation par un moteur 35;
l'écrou 34 est immobilisé en rotation par des glissières 36
et 37; l'ergot coopère avec un premier épaulement 30' de la
came, qui est munie d'un second épaulement 30".The cam is kept stationary by a
Le fonctionnement est le suivant:
immédiatement après l'ouverture des pôles, ou avec un
retard donné, le moteur 35 est actionné en rotation,
provoquant le déplacement de l'ergot 32 vers la droite de la
Fig.2., ce qui fait tourner la came 30 dans le sens des
aiguilles d'une montre. Dès que la ligne AB dépasse passe la
ligne de point mort, le ressort 30A se détend brusquement et
entraíne en rotation rapide la came et tout l'ensemble
mobile qui lui est solidaire, c'est-à-dire poutre 4 et
pôles.The operation is as follows:
immediately after the opening of the poles, or with a given delay, the
La position sectionnée est représentée en traits tiretés dans la Fig. 2.The sectioned position is shown in lines dashed lines in Fig. 2.
La fermeture de l'interrupteur se fait en actionnant
le moteur en sens inverse du sens utilisé pour l'ouverture;
l'ergot, en butée sur l'épaulement 30", entraíne la came
dans le sens anti-horaire, jusqu'à passage du point mort,
avec compression du ressort 30A; après quoi l'ergot est
ramené dans la position en butée contre l'ergot 30', prête
pour une nouvelle interruption.The switch is closed by operating
the motor opposite to the direction used for opening;
