Description
La présente invention est relative à un disjoncteur à haute tension comprenant pour chaque pôle, une enveloppe cylindrique remplie de gaz isolant à l'intérieur de laquelle sont disposés les organes de coupure et une résistance, disposée axialement, associée à des moyens pour son insertion temporaire lors de la fermeture du disjoncteur.The present invention relates to a circuit breaker with high voltage including for each pole, an envelope cylindrical filled with insulating gas inside which the cut-off members and a resistor are arranged, axially arranged, associated with means for its temporary insertion when closing the circuit breaker.
On a décrit, dans la demande de brevet français n° 79 05 478, un disjoncteur dans la chambre de coupure duquel sont disposés une résistance et des moyens pour insérer temporairement cette résistance dans le circuit du disjoncteur lors d'une opération d'enclenchement. Ces moyens comprennent un contact solidaire de l'équipage mobile, mais mobile par rapport à ce dernier. C'est la raison pour laquelle on le désigne par contact semi-mobile. Généralement, le contact semi-mobile est une pièce de tungstène choisie massive car elle doit subir le choc d'une opération de fermeture. Ce contact présente donc une masse dont la proportion dans la masse de l'équipage mobile est importante, contribuant ainsi à augmenter la puissance de la commande du disjoncteur. Par ailleurs, le contact de fermeture est de fort encombrement, nécessitant une enveloppe de grand diamètre.We have described, in French patent application n ° 79 05 478, a circuit breaker in the breaking chamber of which a resistor and means are provided for inserting temporarily this resistance in the circuit of the circuit breaker during an interlocking operation. These means include a contact integral with the moving part, but mobile relative to the latter. This is the reason which it is designated by semi-mobile contact. Generally, the semi-mobile contact is a part of tungsten chosen massive because it must undergo the shock of a closing operation. This contact therefore has a mass whose proportion in the mass of the moving assembly is important, thereby helping to increase the power of the circuit breaker control. In addition, the contact of closure is very bulky, requiring a large diameter envelope.
Or, les constructeurs recherchent tous à diminuer la puissance de la commande, de manière à diminuer le prix de revient et d'exploitation du disjoncteur.However, manufacturers are all looking to reduce the power of the command, so as to decrease the price by returns and operating the circuit breaker.
Un premier but de l'invention est de réaliser un disjoncteur du type précité dans lequel les moyens d'insertion de la résistance sont allégés, ce qui permet de réduire la puissance de la commande.A first object of the invention is to provide a circuit breaker of the aforementioned type in which the means resistance are reduced, which allows reduce the power of the control.
Un autre but de l'invention est de réaliser un disjoncteur du type précité dans lequel les moyens d'insertion de la résistance sont de volume réduit, ce qui permet de réduire le diamètre des enveloppes utilisées. Another object of the invention is to provide a circuit breaker of the aforementioned type in which the means resistance are reduced in volume, which reduces the diameter of the envelopes used.
La présente invention a pour objet un disjoncteur selon les revendications.The present invention relates to a circuit breaker according to the claims.
L'invention sera bien comprise par la description ci-après d'un mode préféré de réalisation, en référence au dessin annexé, dans lequel:
- la figure 1 est une vue partielle en coupe axiale d'un pôle de disjoncteur selon l'invention, représenté en position enclenchée,
- les figures 2 à 5 sont des vues similaires du disjoncteur pendant les différentes phases d'une manoeuvre de déclenchement,
- les figures 6 à 7 sont des vues similaires du disjoncteur montrant deux phases successives d'une opération de fermeture.
- FIG. 1 is a partial view in axial section of a circuit breaker pole according to the invention, shown in the engaged position,
- FIGS. 2 to 5 are similar views of the circuit breaker during the different phases of a tripping operation,
- Figures 6 to 7 are similar views of the circuit breaker showing two successive phases of a closing operation.
Dans ce qui suit, on décrira un pôle de disjoncteur, étant bien entendu que l'invention s'applique à un disjoncteur triphasé comprenant trois pôles identiques.In what follows, we will describe a circuit breaker pole, it being understood that the invention applies to a three-phase circuit breaker comprising three identical poles.
On décrira un pôle de disjoncteur de type ouvert, mais bien entendu l'invention s'applique aux disjoncteurs à enveloppe métallique à la terre.We will describe an open type circuit breaker pole, but of course the invention applies to circuit breakers with metal shell to earth.
Dans la Fig. 1, la référence 1 désigne une enveloppe isolante, par exemple en céramique, remplie d'un gaz à bonnes propriétés diélectriques tel que l'hexafluorure de soufre SF6.In Fig. 1, reference 1 designates an envelope insulating, for example ceramic, filled with a gas good dielectric properties such as hexafluoride sulfur SF6.
La chambre de coupure comprend un ensemble fixe
comprenant un cylindre métallique fixe 2 relié à une
première prise de courant non représentée. Une résistance 3
dite "de fermeture" est disposée axialement dans l'enveloppe
1; elle est constituée d'un empilement de disques 3A
entourés d'une gaine isolante latérale 4; une première
extrémité de l'empilement est relié à la première prise de
courant mentionnée plus haut; l'autre extrémité de
l'empilement est terminé par un flasque métallique 6.The breaking chamber includes a fixed assembly
comprising a fixed metal cylinder 2 connected to a
first socket not shown.
Au cylindre métallique 2 est fixé un tube métallique 7
constituant le contact principal fixe du disjoncteur; au
même cylindre 2 est fixé, par des bras métalliques 8, une
portion tubulaire métallique 9 dont l'extrémité 9A est
réalisée en un alliage résistant aux effets de l'arc
électrique. Cette portion tubulaire 9-9A constitue le
contact d'arc, fixe, du disjoncteur.To the metal cylinder 2 is fixed a metal tube 7
constituting the fixed main contact of the circuit breaker; at
same cylinder 2 is fixed, by
Au flasque 6 est fixé, de préférence par des vis 10,
une pièce métallique 11 portant des bras métalliques 12
parallèles à l'axe de l'enveloppe; les bras sont de
préférence au nombre de deux; à l'extrémité de ces bras est
soudée une couronne métallique 13 constituant une électrode
fixe pour l'insertion de la résistance à la fermeture.The
L'ensemble mobile du disjoncteur comprend un flasque
métallique circulaire 15 disposé perpendiculairement à l'axe
de l'enveloppe.The mobile circuit breaker assembly includes a flange
Ce flasque métallique porte une couronne de doigts de
contact 16 constituant les contacts principaux mobiles qui
coopèrent avec le tube 7. Les doigts 16 sont protégés par un
capot pare-effluves 16A.This metallic flange wears a crown of
A l'opposé des contacts 16, le flasque est relié à
deux cylindres coaxiaux dont l'axe commun est l'axe de
l'enveloppe. Ces cylindres, référencés 17 et 18, définissent
un volume de soufflage V1 dans lequel est disposé un piston
de soufflage fixe non représenté. L'un des cylindres, le
cylindre intérieur 17 par exemple, est relié mécaniquement à
une tringle de manoeuvre non représentée; l'autre cylindre,
18, est relié électriquement par des contacts glissants non
représentés, à une seconde prise de courant non représentée.Opposite the
Le cylindre intérieur 17 se prolonge de l'autre côté
du flasque 15 par une portion cylindrique 17A munie
intérieurement de contacts glissants 17B.The
Une portion cylindrique 20, solidarisée au flasque 15,
entoure coaxialement la portion cylindrique 17A. Les
portions cylindriques 17A et 20 définissent un volume
annulaire V2 dans lequel se déplace l'extrémité d'une buse
de soufflage 22 en matériau isolant. La buse 22 possède,
comme les buses classiques de disjoncteur, un col 22A, mais
elle se termine par une couronne 22B constituant un
épaulement facilitant son coulissage dans le volume V2. Un
ressort 24 s'appuie d'une part sur l'épaulement 22B et
d'autre part sur un épaulement 20A à l'extrémité de la
portion cylindrique 20.A
La buse 22 est solidarisée, par une couronne 26 à une
portion tubulaire métallique 30 constituant un contact d'arc
semi-mobile coopérant avec le contact d'arc fixe 9-9A. La
portion 30 est terminée à une extrémité par une pièce de
contact 30A réalisée en un alliage résistant aux effets de
l'arc électrique.The
On note que le flasque 15 comporte des passages 15A
pour le passage du gaz de soufflage du volume V1 au volume
V2 lors d'une opération d'ouverture.Note that the
Le fonctionnement du disjoncteur est le suivant.The circuit breaker works as follows.
En régime de fonctionnement normal, le disjoncteur est
dans la configuration de la Fig.1. Le courant permanent
transite par la première prise de courant, le cylindre 2, le
tube 7, les doigts 16, le flasque 15, le tube 18 et la
seconde prise de courant.In normal operating conditions, the circuit breaker is
in the configuration of Fig. 1. The permanent current
goes through the first socket, cylinder 2, the
tube 7, the
Le déclenchement du disjopncteur est produit par le déplacement de l'ensemble mobile, sous l'action de la commande du disjoncteur, non représentée, vers la droite de la Fig.1.The tripping of the circuit breaker is produced by the displacement of the mobile assembly, under the action of the circuit breaker control, not shown, to the right of Fig. 1.
Dans une première phase, représentée dans la Fig.2,
l'ensemble mobile s'est déplacé de quelques dizaines de mm
vers la droite. Par inertie, et aussi en raison de la montée
de la pression dans le volume V2 derrière la couronne 22B,
due à la compression du gaz dans le volume V1, le sous-ensemble
semi-mobile constitué par la buse (22) et le
contact d'arc (30-30A) reste dans la position qu'ils
occupaient dans la configuration de la Fig. 1. Ceci permet
aux contacts principaux 7 et 16 de se séparer, le courant
commutant dans les contacts d'arc 9-9A et 30-30A. Dans ce
mouvement, le ressort 24 est comprimé.In a first phase, represented in Fig. 2,
the mobile assembly has moved a few tens of mm
to the right. By inertia, and also due to the rise
pressure in the volume V2 behind the
Après une course supplémentaire de l'équipage mobile,
les contacts 16 ont dépassé l'électrode d'insertion 13, et
les contacts d'arc 9-9A et 30-30A sont sur le point de se
séparer, puisque le ressort étant complètement comprimé, le
contact d'arc 30-30A du sous-ensemble semi-mobile est
entraíné par l'ensemble mobile.After an additional run of the moving crew,
the
Après la séparation des contacts d'arc, (Fig. 4), un
arc jaillit entre ces contacts, mais il est rapidement
éteint par le soufflage énergique à travers la buse 22.After the separation of the arcing contacts, (Fig. 4), a
arc spurts between these contacts but it's quickly
extinguished by vigorous blowing through
La pression dans le volume V2 décroít rapidement et,
sous l'effet du ressort, le sous-ensemble semi-mobile
constitué par la buse 22 et le contact d'arc 30-30A reprend
sa position initiale par rapport à l'ensemble mobile.The pressure in volume V2 decreases rapidly and,
under the effect of the spring, the semi-mobile sub-assembly
constituted by the
En fin de manoeuvre d'ouverture, le disjoncteur est,
en position déclenchée, dans la configuration de la Fig.5.
La tension est tenue entre les extrémités des contacts 9A et
30A, ainsi qu'entre l'extrémité des capots pare-effluves 16A
et l'électrode 13, grâce à des distances d'isolement
suffisantes. On note que, dans la configuration déclenchée
du disjoncteur (Fig.5), la distance entre l'extrémité du
capot (16A) du contact principal mobile (16) et l'électrode
(13) est inférieure à la distance entre les extrémités
respectives 9A et 30A des contacts d'arc 9 et 30. C'est
cette particularité qui va permettre l'insertion temporaire
de la résistance lors de l'opération de fermeture du
disjoncteur.At the end of the opening operation, the circuit breaker is,
in the tripped position, in the configuration of Fig. 5.
The voltage is held between the ends of the
Une manoeuvre de fermeture se traduit par un déplacement vers la gauche de l'équipage mobile.A closing operation results in a movement of the moving part to the left.
C'est le capot pare-effluves 16A qui s'approche le
premier de l'électrode d'insertion 13. Lorsque la distance
qui sépare ces deux pièces devient inférieure à la distance
d'isolement (Fig.6), un arc s'amorce entre l'électrode 13 et
le capot pare-effluves 16A, ce qui a pour conséquence
d'insérer la résistance 3 en série dans le circuit du
disjoncteur.It is the
Lorsque, l'ensemble mobile poursuivant sa course, la
distance entre les extrémités respectives des 9A et 30A des
contacts d'arc devient inférieure à la distance d'isolement
(Fig.7), un arc s'amorce entre ces contacts, ce qui a pour
conséquence de court-circuiter la résistance 3. Les
dimensions des divers éléments du disjoncteur et la valeur
de la vitesse de déplacement de l'ensemble mobile sont
choisis pour que la durée d'insertion soit comprise entre 8
et 10 millisecondes, ce qui est la fourchette prescrite par
les utilisateurs de réseaux.When, the moving assembly continuing its course, the
distance between the respective ends of 9A and 30A of
arcing contacts becomes less than the insulation distance
(Fig. 7), an arc begins between these contacts, which has the
consequence of shorting the
Poursuivant se course, l'ensemble mobile retrouve sa position initiale (Fig.1).Continuing to race, the mobile assembly regains its initial position (Fig. 1).
Les moyens d'insertion de la résistance à la fermeture qui viennent d'être décrits permettent de résoudre les problèmes techniques énoncés dans le préambule du présent mémoire:
- réduire la masse des éléments liés à l'ensemble
mobile, ce qui est réalisé puisque les masses
supplémentaires viennent seulement de l'allongement de la
buse 22, des contacts glissants 18 et duressort 24, ce qui, au total, est très faible. - diminuer l'encombrement. Ce problème est résolu puisque l'électrode d'insertion est de diamètre inférieur au capot pare-effluves 16A de la couronne des doigts de contacts principaux 16.
- reduce the mass of the elements linked to the mobile assembly, which is achieved since the additional masses only come from the extension of the
nozzle 22, the slidingcontacts 18 and thespring 24, which, in total, is very small. - reduce clutter. This problem is solved since the insertion electrode is of smaller diameter than the
corona hood 16A of the crown of themain contact fingers 16.
