Description
La présente invention a pour objet un perfectionnement aux collecteurs tournants fonctionnant selon un axe sensiblement vertical, permettant d'en accroître la sécurité et la fiabilité, tout en simplifiant leur construction, leur entretien et leur réparation.The present invention relates to an improvement in rotary manifolds operating along a substantially vertical axis, making it possible to increase safety and reliability, while simplifying their construction, maintenance and repair.
Les collecteurs rotatifs à axe vertical sont utilisés pour la transmission de courants électriques continus ou alternatifs entre une partie fixe et une partie mobile pouvant effectuer une rotation de plus de 360°Rotary collectors with vertical axis are used for the transmission of direct or alternating electric currents between a fixed part and a mobile part that can rotate more than 360 °
Ces collecteurs transmettent des courants de puissance, de commande, de mesure ou de signalisation, en tension continue, ou bien basse ou haute fréquence et peuvent posséder un grand nombre de passages.These collectors transmit power, control, measurement or signaling currents, in direct voltage, or low or high frequency and can have a large number of passages.
Ils doivent apporter le moins de perturbations possibles dans la transmission de ces courants, ce qui est particulièrement important pour les signaux à bas niveau.They should bring as little disturbance as possible into the transmission of these currents, which is particularly important for low level signals.
D'une façon générale, on leur demande une grande sécurité de fonctionnement et une longue durée de vie.In general, they are asked for high operational safety and a long service life.
Dans certains cas, par exemple pour les coupoles d'observatoires, les tourelles marines ou les plate-formes pétrolières, Ils peuvent être de grande dimension.In some cases, for example for observatory domes, marine turrets or oil platforms, they can be large.
Enfin, ils sont souvent employés dans des conditions difficiles conjuguant par exemple une utilisation en milieu marin et tropical avec une ambiance corrosive et explosive et des conditions vibratoires dures.Finally, they are often used in difficult conditions, for example combining use in a marine and tropical environment with a corrosive and explosive atmosphere and harsh vibrational conditions.
Selon les techniques classiques actuelles, ces collecteurs sont constitués par des bagues ou des couronnes conductrices liées soit à la partie fixe de l'installation, soit à la partie mobile et sur lesquelles viennent s'appuyer des contacts électriques solidaires de l'autre partie.According to current conventional techniques, these collectors consist of rings or conductive rings linked either to the fixed part of the installation, or to the mobile part and on which come to rest electrical contacts integral with the other part.
Les incidents rencontrés en utilisation résultent généralement de la présence de condensations internes ou de poussières provenant de l'usure des parties mobiles, ou bien de l'introduction.de corps étrangers solides, liquides ou gazeux. Il en résulte des perturbations électriques, des court-circuits internes ou autres incidents préjudiciables à la sécurité et à la longévité du fonctionnement.Incidents encountered in use generally result from the presence of internal condensations or dust from the wear of the moving parts, or else from the introduction of solid, liquid or gaseous foreign bodies. This results in electrical disturbances, internal short circuits or other incidents detrimental to safety and the longevity of operation.
D'autre part, dans le cas des collecteurs de grand diamètre la réalisation et la protection des couronnes ou des bagues posent des problèmes pratiques croissant avec leur taille alors que leur grande dimension est généralement imposée par la nécessité de monter le collecteur autour d'autres organes occupant la partie centrale.On the other hand, in the case of large diameter collectors, the production and protection of crowns or rings poses increasing practical problems with their size whereas their large dimension is generally imposed by the need to mount the collector around other organs occupying the central part.
La présente invention est caractérisée par l'utilisation de bandes métalliques à la place de bagues ou de couronnes et par une disposition particulière des divers organes constitutifs.The present invention is characterized by the use of metal bands in place of rings or crowns and by a particular arrangement of the various constituent bodies.
Pour comprendre l'objet de la présente invention, on se rap- portera aux figures des planches jointes en annexe.To understand the object of the present invention, reference will be made to the figures of the plates attached in the appendix.
Les figures 1 et 2 donnent la description schématique des solutions classiques actuellement employées et les figures suivantes les dispositions selon la présente invention afin de montrer les points essentiels par lesquels elle en diffère et les possibilités de réalisation.Figures 1 and 2 give the schematic description of the conventional solutions currently used and the following figures the arrangements according to the present invention to show the essential points by which it differs and the possibilities of realization.
La figure 1 montre la vue schématique en coupe d'un collecteur tournant à bagues de type classique destiné à être utilisé en position sensiblement verticale. Ce collecteur tournant comporte un corps tubulaire (1) solidaire d'une embase (2), cet ensemble constituant l'enveloppe interne que nous supposerons fixe pour faciliter la présente explication.Figure 1 shows the schematic sectional view of a rotating collector with rings of conventional type intended to be used in a substantially vertical position. This rotary manifold comprises a tubular body (1) integral with a base (2), this assembly constituting the internal envelope which we will assume to be fixed to facilitate the present explanation.
Le corps tubulaire intérieur (1) laisse passage à des organes divers, fixes ou mobiles, que nous supposerons contenus dans un volume cylindrique (3).The internal tubular body (1) allows passage to various bodies, fixed or mobile, which we will assume contained in a cylindrical volume (3).
L'ensemble du collecteur est renfermé entre cette enveloppe interne fixe et une enveloppe externe mobile (4).The entire collector is enclosed between this fixed internal envelope and a mobile external envelope (4).
Les passages électriques, figurés pour simplifier au nombre de quatre, sont réalisés à l'aide de bagues conductrices telles que (5) logées dans un support isolant (6) solidaire mécaniquement de l'enveloppe fixe et reliées électriquement par des câbles à la partie fixe de l'installation générale.The electrical passages, shown to simplify the number of four, are made using conductive rings such as (5) housed in an insulating support (6) mechanically secured to the fixed casing and electrically connected by cables to the part of the general installation.
La liaison électrique avec la partie mobile est établie par des trotteurs conducteurs (7) constitués par des balais carbo-métalliques ou des contacts en métaux ou alliage appropriés adaptés aux tensions et courants à transmettre. Ces frotteurs sont en liaison électrique avec les câbles de transmission des courants à la partie mobile par l'intermédiaire de supports (8) avec lesquels ils sont en liaison souple.The electrical connection with the movable part is established by conductive trotters (7) constituted by carbon-metal brushes or contacts made of suitable metals or alloy adapted to the voltages and currents to be transmitted. These wipers are in electrical connection with the cables for transmitting currents to the mobile part by means of supports (8) with which they are in flexible connection.
Les supports de frotteurs tels que (8) sont fixés mécaniquement sur une pièce isolante (9) qui permet leur fixation sur l'enveloppe externe (4) supposée mobile.The friction shoe supports such as (8) are mechanically fixed to an insulating part (9) which allows them to be fixed to the external casing (4) assumed to be mobile.
On peut remarquer dans la présente description schématique que les bagues telles que (5) sont séparées les unes des autres par des cloisons isolantes telles que (10) qui ont pour'rôle d'augmenter la distance d'isolement entre elles afin de remédier dans une certaine mesure à des inconvénients rencontrés dans la pratique.It can be noted in the present schematic description that the rings such as (5) are separated from each other by insulating partitions such as (10) which have the role of increasing the isolation distance between them in order to remedy in some extent to the disadvantages encountered in practice.
Ces inconvénients résultent principalement du fait qu'après un certain temps de fonctionnement on constate la présence de dépôts abrasifs et conducteurs découlant de l'usure normale des contacts rotatifs se combinant avec les condensations internes résultant de la respiration de l'enceinte en fonction des variations de température. Il peut venir s'y ajouter l'influence néfaste d'une introduction de liquides conducteurs (eau de mer par exemple) ou de corps gras introduits par les agents de graissage des organes de rotation. Ces dépôts ou ruissellements suivent principalement le chemin indiqué par les flèches (f) et restent en partie enfermés dans les logements circulaires des bagues en provoquant les inconvénients signalés précédemment.These drawbacks mainly result from the fact that after a certain period of operation, the presence of abrasive and conductive deposits is observed, arising from the normal wear of the rotary contacts, combining with the internal condensations resulting from the breathing of the enclosure as a function of variations of temperature. There may be added the harmful influence of an introduction of conductive liquids (sea water for example) or fatty substances introduced by the lubricating agents of the rotating members. These deposits or runoff mainly follow the path indicated by the arrows (f) and remain partly enclosed in the circular housings of the rings, causing the drawbacks mentioned previously.
Malgré toutes les précautions prises pour améliorer les états de surface afin de réduire l'usure et augmenter l'étanchéité, il est très difficile de supprimer ces ennuis et même la surpression de l'atmosphère interne, solution compliquée et coûteuse, ne peut y remédier entièrement.Despite all the precautions taken to improve the surface conditions in order to reduce wear and increase sealing, it is very difficult to remove these problems and even the overpressure of the internal atmosphere, a complicated and expensive solution, cannot remedy them. entirely.
La figure 2 montre la disposition schématique générale des collecteurs ou type à couronnes, lesquels comportent, comme dans le cas précédent, une enveloppe interne constituée par un corps tubulaire (11) et une semelle (12), cette enveloppe interne laissant libre passage à un volume cylindrique (13) et étant supposée fixe.FIG. 2 shows the general schematic arrangement of the collectors or crown type, which comprise, as in the previous case, an internal envelope constituted by a tubular body (11) and a sole (12), this internal envelope allowing free passage to a cylindrical volume (13) and being assumed to be fixed.
L'enveloppe externe (14) est supposée tournante par rapport à l'enveloppe interne et les liaisons entre la partie fixe et la partie mobile sont établies par des couronnes conductrices telles que (15), montées sur le support isolant (16), sur lesquelles viennent s'appuyer des contacts tels que (17) et (18) fixés sur la pièce isolante (19) solidaire de la partie tournante.The outer casing (14) is assumed to rotate relative to the inner casing and the connections between the fixed part and the movable part are established by conductive rings such as (15), mounted on the insulating support (16), on which are supported contacts such as (17) and (18) fixed on the insulating part (19) integral with the rotating part.
On remarque que cette disposition de contacts en dessus et en dessous des couronnes découle de la nécessité de tenue aux accélérations dans le sens vertical.Note that this arrangement of contacts above and below the rings results from the need to withstand acceleration in the vertical direction.
Ce qui a été précédemment dit des inconvénients dus aux dépôts sur les surfaces internes s'applique évidemment à la présente disposition. On remarquera à ce sujet que les problèmes d'usure seront surtout importants pour les contacts supérieurs tels que (17) par le fait que ces dépôts restent de préférence à la partie supérieure des surfaces horizontales.What has already been said of the disadvantages due to deposits on the internal surfaces obviously applies to this provision. It will be noted in this regard that the wear problems will be especially important for the upper contacts such as (17) by the fact that these deposits preferably remain at the upper part of the horizontal surfaces.
Pour comprendre le perfectionnement aux collecteurs tournants proposé par la présente invention, on se référera à la figure (3) qui en donne la représentation schématique en élévation et en coupe.To understand the improvement in rotary manifolds proposed by the present invention, reference is made to Figure (3) which gives a schematic representation in elevation and in section.
Comme dans les descriptions précédentes, le collecteur comporte une enveloppe interne (21) et une enveloppe externe (22) tournant par rapport à celle-ci. Les liaisons électriques entre la partie fixe et la partie mobile sont réalisées par des bandes conductrices telles que (24) et (25) encastrées dans des rainures circulaires de positionnement établies à la partie inférieure d'un plateau isolant (26). Sur ces bandes viennent s'appuyer des contacts tels que (27) et (28) montés sur des supports isolants tels que (29) solidaires de la partie mobile.As in the preceding descriptions, the collector comprises an internal envelope (21) and an external envelope (22) rotating relative to the latter. The electrical connections between the fixed part and the mobile part are made by conductive strips such as (24) and (25) embedded in circular positioning grooves established at the bottom of an insulating plate (26). On these bands are supported contacts such as (27) and (28) mounted on insulating supports such as (29) integral with the movable part.
On remarquera que pour une autre bande telle que (25) les contacts mobiles (30) et (31) sont montés sur un support (32) éloigné du support (29) de la bague voisine.It will be noted that for another strip such as (25) the movable contacts (30) and (31) are mounted on a support (32) remote from the support (29) of the neighboring ring.
Enfin, entre un étage supérieur tel que décrit ci-dessus et un étage identique situé au dessous se trouve interposé un déflecteur (33) qui ne porte aucune pièce électrique nue et qui a pour but de protéger l'étage inférieur des dépôts pouvant venir d'au dessus.Finally, between an upper stage as described above and an identical stage situated below, there is interposed a deflector (33) which does not carry any bare electrical parts and which aims to protect the lower stage from deposits which may come from it. 'above.
Les figures 4 à 10 donnent, à titre indicatif et non limitatif, des exemples schématiques permettant de mieux faire comprendre la présente invention et d'en apercevoir les possibilités pratiques de réalisation.FIGS. 4 to 10 give, by way of nonlimiting indication, schematic examples making it possible to better understand the present invention and to see its practical possibilities of implementation.
La figure 4 donne la vue développée d'une bande collectrice laquelle comporte la bande proprement dite (41) sur laquelle sont brasées, à chaque extrémité, des pattes (42), de même épaisseur que la bande, entre lesquelles sont également brasées d'autres pattes telles que (43), les dites pattes servant à la fixation et au raccordement électrique de la bande ainsi qu'il sera exposé ultérieurement.Figure 4 gives the developed view of a collecting strip which comprises the actual strip (41) on which are brazed, at each end, tabs (42), of the same thickness as the strip, between which are also brazed other tabs such as (43), said tabs used for fixing and electrical connection of the strip as will be explained later.
La figure 5 montre la même bande mise en forme circulaire telle qu'elle se trouvera après montage dans les rainures du plateau support de bandes.Figure 5 shows the same band shaped circularly as it will be after mounting in the grooves of the band support plate.
La figure 6 représente la vue en demi coupe d'un ensemble plateau-collecteur et contacts. Le plateau isolant circulaire (51) étant fixé par des vis telles que (52) sur un support tubulaire (53) supposé fixe. Ce plateau comporte, sous sa partie inférieure (58) des rainures circulaires dans lesquelles viennent s'encastrer les bandes collectrices (54) à (57) et entre ces rainures se trouvent des cloisons verticales telles que 59 destinées a allonger les lignes d'isolement entre bagues et à canaliser vers le bas les dépôts et condensations.FIG. 6 represents the half-section view of a tray-collector and contacts assembly. The circular insulating plate (51) being fixed by screws such as (52) on a tubular support (53) assumed to be fixed. This plate has, under its lower part (58) circular grooves in which the collector strips (54) to (57) are fitted and between these grooves there are vertical partitions such as 59 intended to lengthen the lines of isolation. between rings and channel deposits and condensations downwards.
Dans le même but des déflecteurs isolants tels par exemple que figuré en (72) peuvent être placés entre les divers étages du collecteur. Pour donner des exemples de fixation et de raccordement des bagues collectrices on peut voir sur cette figure que la bande (54) est maintenue par des clavettes élastiques conductrices telles que (60) comportant une partie roulée (61) dans laquelle vient se souder le conducteur (62). Une autre possibilité est donnée relativement la bande (56) dont les pattes portent des trous taraudés où viennent se visser des tiges filetées telles que (63) sous les têtes desquelles sont serrées des cosses (64) recevant un conducteur (65). Tout l'ensemble des raccordements effectués à la partie supérieure du plateau est bloqué et protégé par un compoundage (66).For the same purpose insulating deflectors such as that shown in (72) can be placed between the various stages of the collector. To give examples of fixing and connecting the slip rings it can be seen in this figure that the strip (54) is held by elastic conductive keys such as (60) comprising a rolled part (61) in which the conductor is welded (62). Another possibility is given relatively the strip (56) whose legs carry threaded holes where threaded rods are screwed such as (63) under the heads of which are clamped lugs (64) receiving a conductor (65). All of the connections made to the upper part of the plate are blocked and protected by compounding (66).
On remarquera que les bandes (54) et (56) reçoivent des contacts doubles (66), (67) et (68), (69) qui viennent s'appuyer sur les faces latérales verticales des dites bandes. Cette disposition ayant pour but d'assurer une bonne tenue aux vibrations dans le sens perpendiculaire à l'axe XY. D'autre part, si ces contacts sont, pour simplifier la description, figurés dans le plan de coupe, ils sont avantageusement décalés légèrement de part et d'autre de celui-ci ainsi. qu'il sera expliqué ultérieurement.It will be noted that the strips (54) and (56) receive double contacts (66), (67) and (68), (69) which come to bear on the vertical lateral faces of said strips. The purpose of this arrangement is to ensure good resistance to vibration in the direction perpendicular to the XY axis. On the other hand, if these contacts are, to simplify the description, shown in the cutting plane, they are advantageously offset slightly on either side of it as well. that it will be explained later.
Ces contacts (66) à (69) sont placés sur un support isolant (70) fixé sur un corps tubulaire (71) lequel tourne par rapport au corps (53) selon le même axe vertical XY.These contacts (66) to (69) are placed on an insulating support (70) fixed on a tubular body (71) which rotates relative to the body (53) along the same vertical axis XY.
Les contacts s'appuyant sur les bandes (55) et (57) sont montés sur d'autres supports isolants similaires à (70) ceci afin d'augmenter la distance d'isolement entre deux contacts successifs, tels que (67) et (68), placés sur un même support.The contacts resting on the strips (55) and (57) are mounted on other insulating supports similar to (70) this in order to increase the insulation distance between two successive contacts, such as (67) and ( 68), placed on the same support.
La figure (7) qui donne une vue schématique en élévation permet de mieux comprendre les raisons d'une disposition des contacts dans le genre de celle indiquée ci-dessus en considérant que l'axe AB correspond au plan de coupe de la figure précédente et en reprenant les mêmes repères de bandes.FIG. (7) which gives a schematic elevation view makes it possible to better understand the reasons for a contact arrangement of the kind indicated above, considering that the axis AB corresponds to the section plane of the previous figure and using the same strip marks.
Si on dispose par exemple la bande intérieure (54) et la bande intermédiaire (56) de telle sorte que pour chacune de ces bandes leurs deux bouts se referment dans la partie repérée m, n on voit que par suite de leur décalage angulaire lorsqu'un des contacts tel que (66) passera à l'endroit du raccordement, l'autre contact tel que (67) en sera dégagé. Si d'autre, part un autre support de contacts correspondant à ces deux bandes est placé dans la partie p, q symétrique, les liaisons électriques seront sûrement assurées pour chaque bande par au moins trois contacts.If, for example, the inner strip (54) and the intermediate strip (56) are arranged so that for each of these strips their two ends close in the part marked m, n it can be seen only as a result of their angular offset when one of the contacts such as (66) will pass to the location of the connection, the other contact such as (67) will be released. If on the other hand, another contact support corresponding to these two strips is placed in the symmetrical part p, q, the electrical connections will surely be secured for each strip by at least three contacts.
Enfin, si les supports de contacts des bandes collectrices (55) et (57) sont placées dans les parties r, s et t, u de l'axe CD on voit que par suite de leur éloignement il sera facile d'assurer un bon isolement des uns par rapport aux autres.Finally, if the contact supports of the collector strips (55) and (57) are placed in the parts r, s and t, u of the axis CD we see that, as a result of their distance, it will be easy to ensure good isolation from each other.
Les contacts utilisés peuvent être de tout type connu et par exemple en alliages métalliques ou en matériaux carbo-métalliques et montés sur d-es lames élastiques ou des supports appropriés réalisés selon des règles de l'art, en fonction de la nature des courants transmis et des servitudes particulières imposées.The contacts used can be of any known type, for example made of metal alloys or carbon-metallic materials and mounted on elastic blades or suitable supports produced according to the rules of the art, depending on the nature of the currents transmitted. and specific easements imposed.
A titre indicatif, la figure 8 donne en coupe développée un exemple de réalisation permettant de faciliter le montage et démontage des contacts. On voit sur cette figure que le plateau isolant (80) porte la bande (81) logée dans la rainure circulaire vue en (82), laquelle bande y est fixée par la clavette élastique (83) passant au travers d'une ouverture de la patte (84) laquelle clavette sert aussi d'amenée de courant. Sur la partie (85) de la bande, dégagée en dessous de la rainure du plateau viennent s'appuyer, de part et d'.autre, les contacts (86) et (87) sur une face, (88) et (89) sur l'autre face. Ces contacts sont montés sur des lames élastiques tenues par les supports isolants (90) et (91) pouvant tourner autour des axes 0 et 0' perpendiculaires au plan de la figure.By way of indication, FIG. 8 gives in developed section an exemplary embodiment making it easier to assemble and disassemble the contacts. We see in this figure that the insulating plate (80) carries the strip (81) housed in the circular groove seen in (82), which strip is fixed there by the elastic key (83) passing through an opening of the tab (84) which key also serves as a current supply. On the part (85) of the strip, released below the groove of the plate, come to bear, on both sides, the contacts (86) and (87) on one side, (88) and (89 ) on the other side. These contacts are mounted on elastic blades held by the insulating supports (90) and (91) which can rotate around the axes 0 and 0 'perpendicular to the plane of the figure.
On comprend que les contacts peuvent être dégagés pour le démontage en tournant les supports dans les sens f et f' ou bien engagés par la manoeuvre inverse.It is understood that the contacts can be released for disassembly by turning the supports in the directions f and f 'or else engaged by the reverse operation.
On notera d'autre part que les dits supports étant mécaniquement fixés sur une pièce (92) mobile par rapport au plateau (80) les contacts montés sur (90) ou (91) sont disposés en sens inverse pour qu'il n'y ait pas de phénomène de broutement sur les deux jeux de contacts quel que soit le sens de rotation.It will also be noted that said supports being mechanically fixed to a part (92) movable relative to the plate (80) the contacts mounted on (90) or (91) are arranged in opposite directions so that there there is no chattering phenomenon on the two sets of contacts regardless of the direction of rotation.
La présente invention prévoit également qu'afin de faciliter le montage ou le démontage du collecteur le (ou les) plateau(x) porte bandes peuvent être réalisés en une seule pièce où en plusieurs et que pour les mêmes raisons une bande collectrice peut être partagée en deux ou plusieurs parties mises bout à bout. Dans ce cas, les contacts seront disposés selon les règles de l'art pour assurer une bonne sécurité des liaisons électriques.The present invention also provides that in order to facilitate the mounting or dismounting of the collector, the strip holder (s) can be made in one piece or in several and that for the same reasons a collecting strip can be shared. in two or more parts placed end to end. In this case, the contacts will be arranged according to the rules of the art to ensure good security of the electrical connections.
Il est également prévu que les plateaux et autres pièces isolantes peuvent être réalisés par tout moyen connu en matériaux appropriés et que des pièces électriques ou mécaniques peuvent y être directement incorporées, par exemple au moulage.It is also intended that the plates and other insulating parts can be produced by any known means of materials suitable and that electrical or mechanical parts can be directly incorporated therein, for example in molding.
Les figures 9 et.10 donnent des exemples de la disposition générale possible de collecteurs selon la présente invention.Figures 9 and 10 give examples of the possible general arrangement of collectors according to the present invention.
Selon la figure 9 le collecteur comporte une enveloppe extérieure (100) de forme cylindrique mobile en rotation selon l'axe vertical XY et tournant par rapport à une enveloppe circulaire interne (101), ces deux enveloppes constituant une enceinte annulaire et laissant en leur centre un passage cylindrique libre (103).According to Figure 9 the collector comprises an outer casing (100) of cylindrical shape movable in rotation about the vertical axis XY and rotating relative to an internal circular casing (101), these two casings constituting an annular enclosure and leaving in their center a free cylindrical passage (103).
Les plateaux supports de bandes sont fixés sur la pièce tubulaire (104) solidaire mécaniquement de l'enveloppe (101). Les supports de contacts sont montés sur la pièce tubulaire (105) laquelle est mobile en rotation par rapport à l'enveloppe (101) et peut être entraînée par l'enveloppe (100) lorsqu'on la solidarise à celle-ci par un doigt d'entraînement (106). On voit qu'avec une telle disposition tous les équipements électriques internes peuvent être facilement assemblés sur l'enveloppe (101), l'ensemble ainsi constitué étant ensuite coiffé par l'enveloppe extérieure (100) avec laquelle les liaisons électriques sont établies par câbles souples. Pour faciliter le montage et le démontage des éléments internes la pièce (105) possède de larges ouvertures telles que (107) et les parties intermédiaires telles que (108) servant à la fixation des supports de contacts.The band support plates are fixed to the tubular part (104) mechanically integral with the envelope (101). The contact supports are mounted on the tubular part (105) which is movable in rotation relative to the envelope (101) and can be driven by the envelope (100) when it is secured thereto by a finger drive (106). We see that with such an arrangement all the internal electrical equipment can be easily assembled on the casing (101), the assembly thus formed then being capped by the outer casing (100) with which the electrical connections are established by cables. flexible. To facilitate the assembly and disassembly of the internal elements, the part (105) has large openings such as (107) and the intermediate parts such as (108) used for fixing the contact supports.
Selon la disposition schématisée par la figure 10 les dispositions sont similaires mais tous les ensembles électriques sont disposés sur le couvercle (110) fermant la partie supérieure de la cuve (111). Les plateaux sont montés sur le support tubulaire (112) solidaire du couvercle (110) et les supports de contacts sur la pièce tubulaire (113) supportée par un chemin de roulement (114) laquelle pièce peut être solidarisée en rotation avec la cuve (111) par l'intermédiaire d'un doigt (115).According to the arrangement shown schematically in Figure 10 the arrangements are similar but all the electrical assemblies are arranged on the cover (110) closing the upper part of the tank (111). The plates are mounted on the tubular support (112) integral with the cover (110) and the contact supports on the tubular part (113) supported by a raceway (114) which part can be secured in rotation with the tank (111 ) via a finger (115).
Une telle disposition est particulièrement applicable au cas des collecteurs anti-déflagrants ou bien remplis d'un liquide isolant.Such a provision is particularly applicable in the case of explosion-proof collectors or filled with an insulating liquid.
A partir.des descriptions schématiques données précédemment à titre indicatif et non limitatif on comprendra qu'un collecteur selon la présente invention se différencie de ceux actuellement réalisés par les points principaux suivants :
- Un premier point réside dans le fait que l'es surfaces collectrices sont constituées par des bandes métalliques mises en forme circulaire et encastrées dans des rainures situées au dessous d'un plateau isolant de telle sorte que leurs faces de contact soient verticales. Il en résulte que les corps étrangers introduits accidentellement, ou bien provenant de dégradations internes et de l'usure des pièces mobiles auront peu de tendance à se déposer et à subsister dans le chemin des contacts.
- A first point resides in the fact that the collecting surfaces are formed by shaped metal strips. circular and embedded in grooves located below an insulating plate so that their contact faces are vertical. As a result, foreign bodies introduced accidentally, or coming from internal damage and wear of the moving parts will have little tendency to deposit and remain in the contact path.
Un second point résulte du fait que les contacts mobiles de deux bandes voisines sont placés sur des supports différents ce qui permet d'augmenter la distance entre les contacts placés sur un même support isolant et de donner à celui-ci la forme la plus convenable pour allonger les lignes d'isolement et éviter la présence de dépôts nuisibles.A second point results from the fact that the movable contacts of two neighboring strips are placed on different supports, which makes it possible to increase the distance between the contacts placed on the same insulating support and to give the latter the most suitable form for lengthen the isolation lines and avoid the presence of harmful deposits.
Un troisième point réside dans l'économie de métal résultant de l'adoption de bandes pour les surfaces conductrices, surtout vis-à-vis des collecteurs du type à couronnes. Ces bandes étant d'autre part plus faciles à appiovisionner que des feuilles ou des tubes de grande taille devant présenter un excellent état de surface. Pour les collecteurs de grande taille, on notera aussi qu'il est plus facile de protéger éléctrolytiquement. des bandes de grande longueur que des pièces de grande surface.A third point is the economy of metal resulting from the adoption of strips for conductive surfaces, especially vis-à-vis collectors of the crown type. These strips are moreover easier to supply than large sheets or tubes which must have an excellent surface condition. For large collectors, it should also be noted that it is easier to protect electrolytically. strips of great length than pieces of large area.
Une autre différence importante entre la présente invention et les solutions classiques réside dans le fait que le montage du collecteur ne consiste plus dans un empilage de pièces fermées ce qui entraîne une importante addition de tolérances mécaniques, mais dans la mise en plaée de pièces ouvertes dans des logements mécaniquement bien définis.Another important difference between the present invention and the conventional solutions lies in the fact that the mounting of the collector no longer consists in a stack of closed parts which results in a significant addition of mechanical tolerances, but in the placing of open parts in place. mechanically well-defined accommodation.
On doit en-dernier lieu considérer le problème posé en cas de réparation lorsqu'il s'agit d'un collecteur de type classique dont le passage central est occupé par des organes difficilement démontables. En effet lorsque, par exemple par suite d'un court-circuit extérieur, les bagues ou couronnes d'un tel collecteur se trouvent endommagées leur. remplacement nécessite un démontage de l'ensemble de l'installation, alors qu'avec un collecteur à bandes il suffit de séparer verticalement les deux enveloppes et d'ouvrir les bandes détériorées pour pouvoir les sortir et les remplacer.Finally, we must consider the problem posed in the event of repair when it is a conventional type collector whose central passage is occupied by bodies that are difficult to dismantle. Indeed, when, for example as a result of an external short circuit, the rings or crowns of such a collector are damaged. replacement requires disassembly of the entire installation, whereas with a strip collector it suffices to separate the two envelopes vertically and open the damaged strips in order to be able to remove them and replace them.
