Abstract
Description
L'invention concerne un châssis pour maintenir une ampoule à vide de module interrupteur de puissance, comprenant un premier montant et un second montant identiques en matériau électriquement isolant disposés de façon symétrique par rapport à un axe principal de l'ampoule à vide.The invention relates to a chassis for holding a power switch module vacuum interrupter, comprising an identical first and second amounts of electrically insulating material arranged symmetrically with respect to a main axis of the vacuum interrupter.
Un tel châssis est déjà connu du document de brevet US-5864108. Dans ce châssis connu, l'ampoule à vide est maintenue à ses deux extrémités entre les deux montants par deux pièces métalliques de fonderie fixées par plusieurs vis aux montants. Ces pièces de fonderie servent également au raccordement électrique des bornes de l'ampoule à vide. Il existe sur le marché plusieurs types d'ampoule à vide ayant des dimensions différentes et correspondant à des intensités électriques de service différentes pour répondre à des spécifications techniques particulières. Pour pouvoir installer toute une gamme d'ampoules à vide dans un châssis connu du document US-5864108, il est nécessaire de prévoir autant de pièces de fonderie différentes qu'il y a d'ampoules à vide différentes à installer, ce qui est coûteux.Such a frame is already known from US-5864108. In this known frame, the vacuum bulb is held at its two ends between the two uprights by two cast metal parts fixed by several screws to the uprights. These castings are also used for the electrical connection of the terminals of the vacuum interrupter. There are on the market several types of vacuum interrupter having different dimensions and corresponding to different electrical service intensities to meet specific technical specifications. In order to be able to install a whole range of vacuum bulbs in a frame known from US-5864108, it is necessary to provide as many different casting pieces as there are different vacuum bulbs to install, which is expensive. .
Le document US-A-4879441 décrit un châssis pour maintenir une ampoule à vide selon le préambule de la revendication 1.US-A-4879441 discloses a frame for holding a vacuum interrupter according to the preamble of
Par ailleurs, dans un module interrupteur de puissance, il est prévu de disposer plusieurs châssis côte à côte pour maintenir plusieurs ampoules à vide normalement identiques, chaque ampoule à vide servant à interrompre une phase d'une ligne de transport d'électricité. Dans un tel module, les différences de potentiel électrique entre les ampoules à vides disposées côte à côte génèrent des efforts électrodynamiques importants qui tendent à repousser l'une de l'autre les ampoules à vide, ces efforts étant d'autant plus importants que la distance séparant deux ampoules à vide est faible. Il est par conséquent primordial que la structure du châssis recevant l'ampoule à vide soit très rigide pour résister aux efforts électrodynamiques et que l'ampoule à vide ne soit pas décalée axialement entre les deux montants du châssis sous la contrainte de ces efforts.Furthermore, in a power switch module, it is expected to have several frames side by side to maintain several vacuum bulbs normally identical, each vacuum interrupter used to interrupt a phase of a power transmission line. In such a module, the differences in electrical potential between the empty bulbs arranged side by side generate significant electrodynamic forces which tend to push the vacuum bulbs away from one another, these efforts being all the more important as the distance between two vacuum bulbs is low. It is therefore essential that the frame structure receiving the vacuum bulb is very rigid to withstand the electrodynamic forces and that the vacuum bulb is not axially offset between the two uprights of the chassis under the constraint of these efforts.
Le but de l'invention est de proposer une nouvelle construction de châssis qui soit modulable pour un faible coût, c'est-à-dire qui accepte plusieurs ampoules à vide d'une gamme d'ampoules à vide pour un faible coût de réalisation, et qui est apte à supporter des efforts électrodynamiques d'intensité élevée entre phases pour permettre une disposition de plusieurs châssis d'ampoule à vide dans un module interrupteur de puissance avec un faible encombrement.The object of the invention is to provide a new chassis construction that is modular for a low cost, that is to say that accepts several vacuum bulbs of a range of vacuum bulbs for a low cost of implementation and which is adapted to withstand high phase electrodynamic forces between phases to permit a provision of a plurality of vacuum bulb frames in a power switch module with a small footprint.
A cet effet, l'invention a pour objet un châssis pour maintenir une ampoule à vide de module interrupteur de puissance, comprenant un premier montant et un second montant identiques en matériau électriquement isolant disposés de façon symétrique par rapport à un axe principal de l'ampoule à vide, caractérisé en ce qu'une plaque en matériau électriquement isolant est rigidement liée aux montants par encastrement et par clipsage, cette plaque servant au maintien et au centrage de l'ampoule à vide entre lesdits montants.For this purpose, the subject of the invention is a chassis for holding a power switch module vacuum lamp, comprising an identical first and second uprights made of electrically insulating material arranged symmetrically with respect to a main axis of the power switch module. Vacuum bulb, characterized in that a plate of electrically insulating material is rigidly connected to the uprights by fitting and clipping, this plate for maintaining and centering the vacuum bulb between said uprights.
Avec un tel agencement, l'adaptation du châssis à plusieurs types d'ampoules à vide consiste simplement en la réalisation d'une plaque de centrage pour chaque type d'ampoule à vide. Les fonctions de maintien et de centrage de l'ampoule à vide selon l'invention ne sont donc pas réalisées par une pièce métallique de fonderie. Cette plaque de centrage étant de préférence réalisée par moulage et/ou thermoformage d'une matière plastique et/ou composite, elle est d'un coût de revient très faible. D'autre part, cette plaque qui est réalisée en une matière électriquement isolante et qui est fixée aux montants du châssis par encastrement et clipsage permet, avec les pièces métalliques de connexion électrique fixées par des vis aux montants, de renforcer la structure du châssis pour reprendre une grande partie des efforts électrodynamiques qui sont appliqués à l'ampoule à vide dans un module interrupteur de puissance. Cet agencement contribue à l'obtention d'une disposition très compacte des châssis dans un module interrupteur de puissance.With such an arrangement, the adaptation of the chassis to several types of vacuum bulbs is simply the realization of a centering plate for each type of vacuum bulb. The holding and centering functions of the vacuum bottle according to the invention are therefore not performed by a metal casting part. This centering plate is preferably made by molding and / or thermoforming a plastic material and / or composite, it is a very low cost. On the other hand, this plate which is made of an electrically insulating material and which is fixed to the uprights of the frame by fitting and clipping allows, with the metal electrical connection pieces fixed by screws to the uprights, to reinforce the structure of the frame for take up a large part of the electrodynamic forces that are applied to the vacuum interrupter in a power switch module. This arrangement contributes to obtaining a very compact arrangement of the chassis in a power switch module.
L'invention sera maintenant décrite en référence aux dessins annexés qui en illustrent une forme de réalisation à titre d'exemple non limitatif.The invention will now be described with reference to the accompanying drawings which illustrate one embodiment thereof by way of non-limiting example.
La figure 1 est une vue en perspective d'un châssis selon l'invention dans lequel est montée une ampoule à vide.Figure 1 is a perspective view of a frame according to the invention in which is mounted a vacuum bulb.
La figure 2 est une vue en perspective du châssis selon l'invention sans l'ampoule à vide.Figure 2 is a perspective view of the frame according to the invention without the vacuum bulb.
La figure 3 est une vue en perspective de la plaque de centrage du châssis selon l'invention.Figure 3 is a perspective view of the centering plate of the frame according to the invention.
La figure 4 est une vue en perspective d'un montant du châssis selon l'invention.Figure 4 is a perspective view of an amount of the frame according to the invention.
La figure 5 est une vue en coupe du châssis selon l'invention dans lequel est installée une ampoule à vide.Figure 5 is a sectional view of the frame according to the invention in which is installed a vacuum bulb.
La figure 6 est une vue d'ensemble de trois châssis selon l'invention associés au sein d'un même module interrupteur de puissance.Figure 6 is an overview of three frames according to the invention associated within a same power switch module.
Sur la figure 1, on voit un châssis comprenant deux montants identiques 1 et 2 en matériau électriquement isolant disposés verticalement, une première pièce métallique 3A qui est rigidement liée à la partie supérieure des deux montants, une seconde pièce métallique 3B qui est rigidement liée à la partie inférieure des deux montants. Les deux pièces métalliques 3A et 3B servent au raccordement électrique des bornes de l'ampoule à vide 4 qui est disposée entre les deux montant 1 et 2. La pièce métallique 3A a aussi pour fonction de maintenir en suspension l'ampoule à vide 4 entre les deux montants. Comme visible sur la figure 1, une plaque 5 en matériau électriquement isolant est encastrée et clipsée entre les deux montants 1 et 2. Cette plaque 5 sert au maintien et au centrage de l'ampoule à vide entre les deux montants 1 et 2 qui sont fixés de façon amovible sur une platine par des vis 6, cette platine constituant une paroi d'un module interrupteur de puissance.FIG. 1 shows a frame comprising two
Sur la figure 1, l'ampoule à vide a un axe longitudinal principal 7 et les deux montants 1 et 2 identiques sont disposés de façon symétrique par rapport à l'axe 7. L'ampoule à vide 4, disposée verticalement entre les deux montants 1 et 2 verticaux, est maintenue et est centrée entre les deux montants par la plaque de centrage 5.In FIG. 1, the vacuum bottle has a main
Les figures 2, 3, et 4 permettent de mieux comprendre la nature de la liaison mécanique entre la plaque de centrage 5 et les deux montants 1 et 2 du châssis.Figures 2, 3 and 4 provide a better understanding of the nature of the mechanical connection between the
Sur la figure 2, on voit la plaque de centrage 5 qui est encastrée et clipsée entre les deux montants 1 et 2 de formes identiques et disposés verticalement de manière symétrique par rapport à l'axe 7 qui est normal à la plaque de centrage. L'assemblage ainsi obtenu a la forme d'un « H » dans lequel la plaque de centrage est horizontale et les montants sont verticaux.In Figure 2, we see the
Sur la figure 3, on voit que la plaque de centrage 5 a une forme approximativement rectangulaire et comporte une lumière 8 a chacune de ses deux extrémités ainsi qu'une languette de clipsage 9 disposée à proximité d'une lumière 8. Chaque languette 9 comporte un ergot 10. La plaque de centrage 5 comporte encore un alésage cylindrique 11 en position centrale entre les deux lumières 8 et les deux languettes 9. La plaque de centrage 5 peut comporter des nervures de renfort autour des lumières 8 et de l'alésage 11.In FIG. 3, it can be seen that the
Sur la figure 4, on voit que chaque montant tel que 1 ou 2 comporte dans sa partie centrale un plot de positionnement 12 qui est destiné à venir s'engager dans une lumière 8 de la plaque de centrage 5 et une lumière 13 disposée au dessus du plot 12 et dans laquelle s'engage l'ergot 10 d'une languette 9 de la plaque de centrage 5. Par ailleurs, chaque montant 1 ou 2 comporte un évidemment 14 disposé sous le plot 12 et à travers lequel peut être introduite la plaque de centrage 5.In FIG. 4, it can be seen that each upright such as 1 or 2 comprises in its central part a
En revenant à la figure 2, on voit les plots 12 des montants 1 et 2 encastrés dans les lumières 8 de la plaque de centrage 5 et les ergots 10 des languettes 9 de la plaque de centrage 5 clipsés dans les lumières 13 des montants. On comprend donc que les plots 12 des montants 1 et 2 réalisent avec les lumières 8 un positionnement relatif de la plaque par rapport aux montants qui a pour objet d'interdire à la plaque de centrage tout déplacement selon un plan normal à l'axe principal 7. Par ailleurs, les languettes 9 de la plaque de centrage réalisent avec les lumières 13 des montants un positionnement relatif de la plaque par rapport aux montants qui a pour objet d'interdire tout mouvement relatif entre eux le long de l'axe principal 7. Avec cette construction, le châssis est apte à résister à des contraintes de flexion par rapport à l'axe 7 ou de torsion par rapport à cet axe, correspondant à des efforts d'entrephase et a des efforts de boucle qui sont appliqués par l'ampoule à la plaque de centrage 5 dans le plan de cette plaque. En outre ce renforcement de la rigidité du châssis est réalisé sans matière métallique ce qui fait qu'il n'augmente pas les efforts électrodynamiques entre phase que peut subir le châssis.Returning to Figure 2, we see the
L'alésage cylindrique 11 de la plaque de centrage 5 est destiné à recevoir une partie complémentaire cylindrique de l'ampoule à vide, par exemple la partie inférieure 18 (visible sur la figure 5) de celle-ci dans laquelle coulisse la tige de manoeuvre 19 du contact mobile. Vu que l'ampoule à vide est suspendue à la pièce métallique 3A et qu'elle est centrée suivant l'axe vertical 7 entre les deux montants par la pièce de centrage 5, une grande partie des efforts électrodynamiques qui sont appliqués à l'ampoule sont repris par la plaque de centrage 5 puis par les montants si bien que la rigidité de l'ensemble du châssis s'en trouve significativement améliorée. Du point de vue de l'adaptabilité du châssis à plusieurs types d'ampoules à vide, il est important de noter qu'une adaptation de la plaque 5 au type d'ampoule à vide que l'on souhaite monter sur le châssis selon l'invention sera généralement suffisante. Ainsi, si par exemple le diamètre de centrage de l'ampoule est différent, il suffira de réaliser une plaque de centrage ayant un alésage 11 de diamètre correspondant.The
Comme la plaque de centrage 5 peut être introduite entre les deux montants 1 et 2 à travers l'un ou l'autre des évidements 14, il est préférable de prévoir le clipsage des languettes 9 dans des lumières 13 disposées sur la face extérieure des montants. La figure 5 illustre le positionnement de ces languettes 9 sur le côté extérieur des montants 1 et 2. On voit également sur la figure 5 que la plaque de centrage 5 est disposée entre les pièces métalliques 3A et 3B de raccordement électrique suivant l'axe 7.As the
En se reportant à la figure 4, on voit plus particulièrement les moyens de fixation 16 en forme de queue d'aronde prévus sur un montant pour recevoir une vis 17 de fixation des pièces métalliques 3A et 3B aux montants 1 et 2. Ce type de moyen de fixation permet d'effectuer un réglage de la position des pièces métalliques 3A et 3B selon un axe perpendiculaire à l'axe principal 7 pour les centrer par rapport à la pièce de centrage 5 entre les deux montants 1 et 2.Referring to Figure 4, we see more particularly the dovetail-shaped fastening means 16 provided on an upright for receiving a
La figure 6 illustre un module interrupteur de puissance comportant trois châssis disposés côte à côte et dans chacun desquels est installée une ampoule à vide. Les axes longitudinaux de chaque ampoules sont indiqués par 7,7',7" et les montants respectifs des châssis sont indiqués respectivement par 1,2; 1',2';1",2". On voit sur cette figure que les montants d'un châssis et les montants d'un autre châssis adjacent se font face deux à deux. Plus particulièrement, les montants 1,1',1" sont disposés en alignement parallèlement à l'alignement formés par les montants 2,2',2", les deux alignements de montants 1,1',1" et 2,2',2" étant disposés de part et d'autre de l'alignement des axes 7,7',7". L'intérêt fondamental de cette disposition est la compacité obtenue pour le module interrupteur de puissance.Figure 6 illustrates a power switch module having three frames arranged side by side and in each of which is installed a vacuum bulb. The longitudinal axes of each bulbs are indicated by 7.7 ', 7 "and the respective amounts of the frames are respectively indicated by 1.2; 1', 2 '; 1", 2 ". a frame and the uprights of another adjacent frame face each other in pairs, more particularly, the
Les deux montants et la plaque de centrage d'un châssis peuvent être fabriqués à bon marché par moulage et/ou thermoformage d'une matière plastique et/ou composite.The two uprights and the centering plate of a frame can be manufactured cheaply by molding and / or thermoforming a plastic and / or composite material.
