Description

Système de balisage à isolation et étanc éité renforcées Beaconing system with reinforced insulation and waterproofing
Domaine techniqueTechnical area
La présente invention concerne les systèmes de balisage dans lesquels les lampes de balisage sont disposées en série le long d'un circuit primaire en boucle et concerne en particulier un système de balisage à isolation et étanchéité renforcées .The present invention relates to beacon systems in which the beacon lamps are arranged in series along a primary loop circuit and relates in particular to a beacon system with reinforced insulation and tightness.
Etat de la techniqueState of the art
Le système de balisage utilisé sur les pistes d'atterrissage dans un aéroport est généralement constitué d'un circuit primaire série en boucle le long duquel sont raccordées les lampes de balisage alimentées par un courant alternatif dont la valeur efficace est réglée par un régulateur à courant constant selon la brillance souhaitée.The beacon system used on landing strips in an airport generally consists of a primary series loop circuit along which are connected the beacon lamps powered by an alternating current whose effective value is regulated by a current regulator constant according to the desired gloss.
Les lampes de balisage sont isolées chacune du circuit primaire au moyen d'un transformateur de balisage dont les caractéristiques essentielles sont normalisées. Ces transformateurs de courant sont enrobés de caoutchouc et comportent des cordons de raccordement primaires, côté alimentation, ainsi que des cordons de raccordement secondaires, côté lampe.The beacon lamps are each isolated from the primary circuit by means of a beacon transformer whose essential characteristics are standardized. These current transformers are coated with rubber and have primary connection cords on the supply side as well as secondary connection cords on the lamp side.
Plusieurs transformateurs de ce type sont généralement installés dans des regards qui sont en fait des cavités dans le sol disposées en bordure de la piste d'atterrissage. Un regard peut comporter jusqu'à 8 transformateurs ainsi que d'autres équipements complémentaires.Several transformers of this type are generally installed in manholes which are in fact cavities in the ground arranged at the edge of the runway. A manhole can include up to 8 transformers as well as other additional equipment.
Bien que drainés, les regards dans lesquels se trouvent plusieurs transformateurs sont parfois remplis d'eau de pluie ou de ruissellement. Comme les transformateurs sont disposés pêle-mêle dans le regard, la longueur des cordons primaires et secondaires provoque après quelque temps d'utilisation et de maintenance, un mélange de câbles souvent immergé et recouvert de boue qui s'est accumulée avec le temps au fond du regard.Although drained, the manholes in which several transformers are located are sometimes filled with rain or runoff water. As the transformers are arranged pell-mell in the manhole, the length of the primary and secondary cords causes after some time of use and maintenance, a mixture of cables often submerged and covered with mud which has accumulated over time at the bottom of the manhole.
Les raccordements pendent alors en bas du regard et par conséquent, bien que les transformateurs soient hors d'eau, les connecteurs et l'ensemble des câbles se retrouvent en immersion au fond du regard.The connections then hang at the bottom of the manhole and therefore, although the transformers are out of water, the connectors and all the cables are found in immersion at the bottom of the manhole.
La disposition décrite ci-dessus entraîne un certain nombre d'inconvénients majeurs. Tout d'abord, l'emmêlement des câbles augmente les risques de déconnexion des fiches et prises. Mais surtout, le matériel en fond de regard étant souvent immergé et boueux, le repérage des câbles par rapport aux transformateurs est malaisé et source d'erreurs dans la recherche de la boucle concernée, ce qui entraîne des pertes de temps, des essais supplémentaires et des dégâts éventuels.The arrangement described above involves a number of major drawbacks. First of all, tangled cables increase the risk of disconnection of plugs and sockets. But above all, the equipment behind the manhole is often submerged and muddy, the location of the cables in relation to the transformers is difficult and source of errors in the search for the loop concerned, which leads to loss of time, additional tests and possible damage.
En outre, ajouté au fait que les caoutchoucs d'enrobage et de surmoulage possèdent une certaine porosité se dégradant avec le vieillissement, l'inconvénient principal est la mauvaise étanchéité des connexions. La pénétration d'eau dans les fiches primaires entraîne des liaisons avec la terre pouvant aller jusqu'à la destruction des isolants ou par migration, la destruction du transformateur lui-même. La pénétration de l'eau dans les fiches et prises secondaires peut provoquer une certaine dérivation du courant de lampe .In addition, added to the fact that the coating and overmolding rubbers have a certain porosity which degrades with aging, the main drawback is the poor sealing of the connections. The penetration of water into the primary plugs leads to connections with the earth which can go as far as the destruction of the insulators or by migration, the destruction of the transformer itself. The penetration of water into the plugs and secondary sockets can cause a certain diversion of the lamp current.
Exposé de l'inventionStatement of the invention
C'est pourquoi le but général de l'invention est de fournir un système de balisage à isolation et étanchéité renforcées grâce au groupement en un seul bloc multiple des transformateurs placés dans chaque regard. Un autre but de l'invention est de fournir un système de balisage dans lequel chaque transformateur comporte une prise mâle et une prise femelle de sorte que plusieurs transformateurs peuvent être groupés de façon à former un seul bloc accroché à la paroi du regard.This is why the general aim of the invention is to provide a marking system with reinforced insulation and sealing thanks to the grouping in a single multiple block of the transformers placed in each manhole. Another object of the invention is to provide a beacon system in which each transformer has a male plug and a female plug so that several transformers can be grouped so as to form a single block attached to the wall of the manhole.
L'objet de l'invention est un système de balisage, notamment de piste d'atterrissage dans un aéroport, comprenant une source d' alimentation fournissant un courant constant à un circuit primaire et une pluralité de lampes de balisage connectées respectivement au circuit primaire par une pluralité de transformateurs de courant dont le secondaire fournit le courant d'alimentation de la lampe. Un nombre déterminé de lampes de balisage adjacentes sont connectées au circuit primaire respectivement par un nombre déterminé de transformateurs formant un bloc multiple sans câble de connexion, chaque transformateur formant un bloc simple comportant une fiche mâle et une fiche femelle. Les transformateurs sont empilés de façon à constituer le bloc multiple, la fiche mâle d'un des transformateurs étant enfoncée dans la fiche femelle du transformateur immédiatement adjacent. Le bloc multiple est monté en série dans le circuit primaire au moyen de deux cordons primaires connectés respectivement à la fiche mâle du premier transformateur du bloc multiple et à la fiche femelle du dernier transformateur du block multiple.The object of the invention is a beacon system, in particular an airport runway, comprising a power source supplying a constant current to a primary circuit and a plurality of beacon lamps connected respectively to the primary circuit by a plurality of current transformers, the secondary of which supplies the lamp supply current. A determined number of adjacent beacon lamps are connected to the primary circuit respectively by a determined number of transformers forming a multiple block without connection cable, each transformer forming a single block comprising a male plug and a female plug. The transformers are stacked so as to constitute the multiple block, the male plug of one of the transformers being inserted in the female plug of the transformer immediately adjacent. The multiple block is mounted in series in the primary circuit by means of two primary cords connected respectively to the male plug of the first transformer of the multiple block and to the female plug of the last transformer of the multiple block.

Description détaillée de l'inventionDetailed description of the invention
Le système de balisage selon l'invention principalement utilisé pour les pistes d'atterrissage d'aéroport se présente de la façon illustrée sur la figure 1. Un régulateur de courant 10 fournit un courant constant, par exemple 6, 6A au circuit primaire 12. Les lampes de balisage 14-1, 14-2, 14-3, 14-4, 14-5, et 14-6, sont alimentées respectivement par les circuits secondaires des transformateurs de balisage 16-1, 16-2, 16-3, 16-4, 16-5 et 16-6 dont les enroulements primaires sont connectés en série sur le circuit primaire 12. Il est à noter que les transformateurs 16 sont des transformateurs de courant de rapport 1/1. Dans l'exemple illustré sur les figures, ces transformateurs sont des transformateurs de forme torique mais pourraient être aussi bien en tôle El. Les transformateurs 16 sont regroupés dans des regards ou cavités le long de la piste d'atterrissage. Selon l'invention, un groupe pouvant comprendre une pluralité de transformateurs forme un bloc multiple. Ainsi, selon l'exemple illustré sur les figures 2A et 2B, un tel bloc multiple peut comporter 4 transformateurs 22-1, 22-2, 22-3 et 22-4 disposés de façon adjacente sans comporter de cordons primaires exceptés le cordon primaire 24 et le cordon primaire 26 reliés aux extrémités du câble de boucle présent dans le regard de façon à connecter le bloc multiple 20 aux blocs multiples se trouvant dans les deux regards adjacents . Les fiches mâle et femelle correspondantes des couples de transformateurs adjacents sont connectées dans le même alignement correspondant à l'axe 28 des tores illustrés sur la Figure 2B. Une embase de prise femelle secondaire 30-1, 30-2, 30-3 et 30-4 est surmoulée respectivement sur chacun des transformateurs 22-1, 22-2, 22-3 et 22-4, de telle sorte qu'il suffit d'enficher le cordon secondaire en provenance de la lampe, par exemple le cordon secondaire 32 pour le transformateur 22-4. Un porte-étiquette ou tout autre dispositif similaire permet de repérer chaque transformateur et sa connexion secondaire.The beacon system according to the invention mainly used for airport landing strips is presented in the manner illustrated in FIG. 1. A current regulator 10 supplies a constant current, for example 6, 6A to the primary circuit 12. The beacon lamps 14-1, 14-2, 14-3, 14-4, 14-5, and 14-6 are supplied respectively by the secondary circuits of the beacon transformers 16-1, 16-2, 16- 3, 16-4, 16-5 and 16-6 whose primary windings are connected in series on the primary circuit 12. It should be noted that the transformers 16 are current transformers with a 1/1 ratio. In the example illustrated in the figures, these transformers are toroidal transformers but could also be made of sheet metal El. The transformers 16 are grouped in manholes or cavities along the runway. According to the invention, a group which may include a plurality of transformers form a multiple block. Thus, according to the example illustrated in FIGS. 2A and 2B, such a multiple block can comprise 4 transformers 22-1, 22-2, 22-3 and 22-4 arranged in an adjacent manner without comprising primary cords except the primary cord 24 and the primary cord 26 connected to the ends of the loop cable present in the manhole so as to connect the multiple block 20 to the multiple blocks located in the two adjacent manholes. The corresponding male and female plugs of the pairs of adjacent transformers are connected in the same alignment corresponding to the axis 28 of the toroids illustrated in FIG. 2B. A secondary socket socket 30-1, 30-2, 30-3 and 30-4 is overmolded respectively on each of the transformers 22-1, 22-2, 22-3 and 22-4, so that it just plug in the secondary cord coming from the lamp, for example the secondary cord 32 for the transformer 22-4. A label holder or any other similar device makes it possible to identify each transformer and its secondary connection.
Enfin, le bloc multiple 20 est accroché sur la paroi verticale 34 du regard, et de préférence dans la partie haute du regard, par une entretoise 36 disposant de deux blocs-écrous 38 et 40 fixés au mur 34 et serrés de manière à maintenir ensemble les transformateurs du bloc. Il va de soi que la cohésion du bloc multiple ainsi que son accrochage peuvent être réalisés par tout autre moyen sans sortir du cadre de l'invention.Finally, the multiple block 20 is hung on the vertical wall 34 of the manhole, and preferably in the upper part of the manhole, by a spacer 36 having two nut blocks 38 and 40 fixed to the wall 34 and tightened so as to hold together block transformers. It goes without saying that the cohesion of the multiple block as well as its attachment can be achieved by any other means without departing from the scope of the invention.
Selon un premier mode de réalisation de l'invention, chaque transformateur du bloc multiple 20 vu en coupe se présente de la façon illustrée sur la figure 3. Les enroulements 42 et 44 formant les deux parties du tore se trouvent de part et d'autre d'un ensemble de connexion 46 traversant le transformateur et surmoulé dans la partie du transformateur située dans l'axe du tore. Cet ensemble de connexion 46 comprend une fiche mâle 48 et son embase en caoutchouc 50 et une fiche femelle 52, creuse, dont la forme épouse la forme de la fiche mâle 48 et son embase 50. Ainsi, la connexion de deux transformateurs adjacents s'effectue en introduisant la fiche mâle 48 et l'embase 50 du premier transformateur dans la fiche femelle 52 du second transformateur. La fiche mâle 48 est connectée à un conducteur en cuivre 54 et le fond de la fiche femelle est connecté à un conducteur en cuivre 56 de manière à ce que l'enfoncement de la fiche mâle 48 d'un transformateur adjacent provoque la connexion électrique entre le conducteur 54 dudit transformateur et le conducteur 56 du transformateur adjacent. Les deux conducteurs 54 et 56 d'un même transformateur sont reliés respectivement aux deux extrémités de l'enroulement primaire du transformateur. A noter que la fiche mâle peut être intégrée d'un côté ou de l'autre du transformateur et réciproquement pour la fiche femelle .According to a first embodiment of the invention, each transformer of the multiple block 20 seen in section is presented in the manner illustrated in FIG. 3. The windings 42 and 44 forming the two parts of the torus are located on either side of a connection set 46 passing through the transformer and overmolded in the part of the transformer located in the axis of the toroid. This connection assembly 46 comprises a male plug 48 and its rubber base 50 and a female socket 52, hollow, the shape of which matches the shape of the male plug 48 and its socket 50. Thus, the connection of two adjacent transformers is performs by inserting the male plug 48 and the base 50 of the first transformer into the female plug 52 of the second transformer. The male plug 48 is connected to a copper conductor 54 and the bottom of the female plug is connected to a copper conductor 56 so that the insertion of the male plug 48 of an adjacent transformer causes the electrical connection between the conductor 54 of said transformer and the conductor 56 of the adjacent transformer. The two conductors 54 and 56 of the same transformer are connected respectively to the two ends of the primary winding of the transformer. Note that the male plug can be integrated on one side or the other of the transformer and vice versa for the female plug.
Selon un deuxième mode de réalisation illustré en coupe sur la figure 4, l'ensemble de connexion 60 surmoulé dans la partie du transformateur située dans l'axe du tore formé par les enroulements 42 et 44 comprend deux fiches femelles 62 et 64 situées sur les deux faces opposées du transformateur. La connexion de deux transformateurs adjacents s'effectue au moyen d'une double fiche mâle illustrée en coupe sur la figure 4A. Cette double fiche mâle est composée de deux fiches mâles 66 et 68 de chaque côté et d'un bloc cylindrique 70 de préférence en caoutchouc. Grâce à cette double fiche mâle, on peut transformer l'une ou l'autre des fiches femelles 62 ou 64 en fiche mâle en introduisant l'une des fiches mâles 66 ou 68 dans la fiche femelle choisie. Le cylindre 70 sert d'embase venant buter sur l'épaulement se trouvant à l'intérieur de la fiche femelle lorsque la fiche mâle est enfoncée correctement de manière à établir la connexion électrique avec l'un des conducteurs en cuivre 72 ou 74 connectés aux extrémités de l'enroulement primaire du transformateur .According to a second embodiment illustrated in section in FIG. 4, the connection assembly 60 overmolded in the part of the transformer located in the axis of the toroid formed by the windings 42 and 44 comprises two female plugs 62 and 64 located on the two opposite sides of the transformer. The connection of two adjacent transformers is carried out by means of a double male plug illustrated in section in FIG. 4A. This double male plug is composed of two male plugs 66 and 68 on each side and a cylindrical block 70 preferably made of rubber. Thanks to this double male plug, one or the other of the female plugs 62 or 64 can be transformed into a male plug by introducing one of the male plugs 66 or 68 into the chosen female plug. The cylinder 70 serves as a base abutting on the shoulder located inside the female plug when the male plug is inserted correctly so as to establish the electrical connection with one of the copper conductors 72 or 74 connected at the ends of the transformer primary winding.
Le mode de réalisation qui vient d'être décrit dans lequel l'utilisateur a la possibilité de choisir de quel côté du transformateur est placée la fiche mâle permet d' installer un bloc multiple dans un regard sans savoir à priori de quel côté du regard se trouve le cordon primaire mâle ou le cordon primaire femelle. Il suffit à l'installateur de placer une double fiche mâle du côté adéquat de chaque transformateur du bloc multiple après qu' il a déterminé les positions respectives des cordons primaires mâle et femelle. Sans cette possibilité, il pourrait s'avérer que les transformateurs du bloc multiple amenés par l'installateur ne soient pas adaptés au regard et que l'installateur soit obligé de revenir chercher les transformateurs adéquats dans un lieu souvent très éloigné du regard.The embodiment which has just been described in which the user has the possibility of choosing on which side of the transformer is placed the male plug makes it possible to install a multiple block in a manhole without knowing a priori which side of the manhole is finds the primary male cord or the primary female cord. It is sufficient for the installer to place a double male plug on the appropriate side of each transformer of the multiple block after he has determined the respective positions of the primary male and female cords. Without this possibility, it could turn out that the transformers of the multiple unit brought by the installer are not suitable for viewing and that the installer is forced to return to find the appropriate transformers in a place often far from viewing.
A noter qu'on peut prévoir d'intégrer une lampe dans chaque transformateur qui s'allume lorsque le transformateur est connecté dans le circuit primaire. Ceci permet d'éviter à un installateur de manipuler un bloc de transformateurs connecté dans le circuit primaire et donc sous tension.Note that one can plan to integrate a lamp in each transformer which lights up when the transformer is connected in the primary circuit. This prevents an installer from handling a transformer block connected in the primary circuit and therefore live.
Par sa configuration sous forme de bloc comportant plusieurs transformateurs adjacents, l'invention permet la suppression des cordons entre les transformateurs et supprime donc l'emmêlement possible des câbles primaires. En outre, les cordons primaires ne se trouvent plus au fond de regard, souvent immergés dans l'eau (et la boue) de pluie et de ruissellement. Les interfaces de connexion, étanches se trouvent donc toujours hors d'eau. Les seuls câbles mobiles sont les câbles de raccordement au circuit primaire qui sont à la même hauteur que les transformateurs et donc également hors d'eau. By its configuration in the form of a block comprising several adjacent transformers, the invention allows the removal of the cords between the transformers and therefore eliminates the possible tangling of the primary cables. In addition, the primary cords are no longer at the bottom of the manhole, often immersed in water (and mud) of rain and runoff. The waterproof connection interfaces are therefore always find out of water. The only moving cables are the primary circuit connection cables which are at the same height as the transformers and therefore also out of water.
