Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

La présente invention concerne un dispositif de sécurité pour la récupération de produits inflammables pouvant fuir d'un transformateur électrique, ledit dispositif comportant un capot dit de sécurité pour éviter que lesdits produits ne prennent feu et/ou pour éteindre les produits en feu lors de leur fuite. Le dispositif suivant l'invention trouvera de nombreuses applications notamment dans le domaine des équipements pour réseaux de distribution de l'électricité et en particulier aux fosses ou bacs de rétention d'huile pour transformateurs électriques.The present invention relates to a safety device for recovering flammable products that can leak from an electrical transformer, said device comprising a so-called safety cover to prevent said products from igniting and / or extinguishing the products on fire during their leak. The device according to the invention will find many applications in particular in the field of equipment for electricity distribution networks and in particular to pits or oil retention tanks for electrical transformers.

ARRIERE PLAN DE L'INVENTIONBACKGROUND OF THE INVENTION

Il est bien connu que les transformateurs électriques, servant essentiellement à modifier la tension d'un courant, produisent une grande quantité de chaleur qui doit être dissipée. Le refroidissement de ces transformateurs est assuré en immergeant les noyaux et les enroulements des transformateurs dans un fluide caloporteur et isolant électrique. Ce fluide consiste dans un diélectrique tel que les huiles minérales ou les PolyChloroBiphényles (PCB).It is well known that electrical transformers, essentially used to change the voltage of a current, produce a large amount of heat that must be dissipated. The cooling of these transformers is ensured by immersing the cores and the windings of the transformers in a coolant and electrical insulator. This fluid consists of a dielectric such as mineral oils or polychlorinated biphenyls (PCB).

Compte tenu du caractère hautement toxique des PCB, les PCB étant des polluants ubiquitaires, bioaccumulables et persistants dont la toxicité varie selon leur poids moléculaire (selon le nombre d'atomes de chlore) et la configuration spatiale de leurs molécules, les transformateurs de puissance utilisés dans les réseaux électriques sont généralement installés au-dessus d'une fosse de rétention destinée à recueillir l'huile contenue dans ces appareils lorsqu'une fuite se produit.Given the highly toxic nature of PCBs, PCBs being ubiquitous, bioaccumulative and persistent pollutants whose toxicity varies with their molecular weight (depending on the number of chlorine atoms) and the spatial configuration of their molecules, the power transformers used In the electrical networks are usually installed above a retention pit intended to collect the oil contained in these devices when a leak occurs.

Usuellement, les fosses disposées sous les transformateurs électriques sont remplies de galets.Usually, the pits arranged under the electrical transformers are filled with pebbles.

Par ailleurs, il est préconisé de ne pas installer un transformateur dans un endroit exposé à des conditions telles que circulation routière, atmosphère corrosive ou chaleur élevée. De plus, sur le plancher autour du transformateur il ne doit pas y avoir d'avaloir pour éviter qu'une éventuelle fuite de fluide se transforme, par le réseau d'égouts, en rejet dans le milieu naturel.In addition, it is recommended not to install a transformer in a place exposed to conditions such as road traffic, corrosive atmosphere or high heat. In addition, on the floor around the transformer there should be no drain to prevent any leakage of fluid is transformed, through the sewer system, into the natural environment.

De telles fosses remplies de galets ne permettent pas d'assurer une sécurité suffisante en cas d'inflammation des huiles, le feu pouvant alors se propager et causer des dégâts importants.Such pits filled with pebbles do not provide sufficient safety in case of ignition of the oils, the fire can then spread and cause significant damage.

Afin de remédier à cet inconvénient, on a déjà proposé qu'un bac ou une fosse soit placé sous le transformateur pour recueillir les fuites liquides typiquement à base d'hydrocarbures pouvant s'écouler du transformateur, le capot de protection qui le recouvre comprenant quant à lui, typiquement, des lamelles rapprochées, pentues, réservant entre elles un espace assurant au produit coulant un accès à bac.In order to remedy this drawback, it has already been proposed that a tank or a pit be placed under the transformer to collect the liquid leaks typically based on hydrocarbons that can flow from the transformer, the protective cover that covers it including to it, typically slats close together, sloping, reserving between them a space ensuring the product flow access to ferry.

Un tel système d'extinction pour bac ou fosse de rétention d'huile polluante a été mis au point et commercialisé par la société demanderesse, la société GMT, depuis 1996, sous la référence BAF ou IC.Such a fire extinguishing system for polluting oil collection tank or pit has been developed and marketed by the plaintiff company, the company GMT, since 1996, under the reference BAF or IC.

Ce type de système est constitué d'un capot comprenant des lamelles rapprochées, pentues réservant entre elles un espace assurant auxdits produits coulants un accès au bac ou à la fosse tout en évitant une alimentation suffisante en oxygène pour permettre d'entretenir une combustion des huiles si ces dernières devaient prendre feu. Chaque lamelle est réalisée en tôle pliée de manière à former un profilé comprenant une partie supérieure bordée sur ses côtés longitudinaux de deux éléments sensiblement verticaux de hauteurs différentes pour créer l'inclinaison de la lamelle. Lesdits éléments verticaux sont repliés dans leur partie inférieure dans une même direction pour former des pattes d'appui globalement horizontales, la patte d'appui de l'élément vertical le plus haut prenant appui sur la patte d'appui de l'élément vertical le plus bas.This type of system consists of a hood comprising slats close together, steep reserving between them a space ensuring said flowing products access to the tank or pit while avoiding a sufficient supply of oxygen to allow maintenance of a combustion of oils if they were to catch fire. Each slat is made of sheet metal folded so as to form a profile comprising an upper portion bordered on its longitudinal sides of two substantially vertical elements of different heights to create the inclination of the slat. Said vertical elements are folded in their lower part in the same direction to form generally horizontal bearing lugs, the support lug of the uppermost vertical element bearing on the support lug of the vertical element the lower.

Afin d'améliorer la sécurité, on a également proposé un dispositif d'extinction pour bac ou fosse de rétention d'huile polluante dont l'écoulement de l'huile est plus rapide. C'est le cas par exemple de la demande de brevet international WO2009/016203 déposée par la Demanderesse. Le dispositif comprend un capot coiffant un bac ou une fosse et comportant des lamelles rapprochées, chaque lamelle présentant des pentes d'écoulement multiples, réservant entre elles un espace assurant auxdits produits coulants un accès à au bac ou à la fosse.To improve safety, it has also been proposed an extinguishing device for tank or polluting oil retention pit whose oil flow is faster. This is the case, for example, of the international patent application WO2009 / 016203 filed by the Applicant. The device comprises a cap covering a tray or a pit and having close slats, each slat having multiple flow slopes, reserving between them a space ensuring said flowing products access to the tray or the pit.

Tous ces dispositifs améliorent nettement la sécurité autour des transformateurs électriques en évitant toute propagation d'un feu en étouffant ce dernier en cas d'inflammation des huiles et en permettant une récupération des huiles au fond du bac ou de la fosse au moyen d'une pompe ou similaire.All these devices significantly improve the safety around electrical transformers by preventing any fire spreading by smothering the latter in case of igniting the oils and allowing recovery of the oils at the bottom of the tank or pit by means of a pump or the like.

Toutefois, pour de gros transformateurs, il est nécessaire de réaliser de gros travaux de terrassement et de construction d'une fosse en béton armé grevant considérablement la durée des travaux et leurs coûts. Les coûts sont encore plus importants lorsque le sol est rocailleux, la nature du sol nécessitant de gros moyens techniques pour creuser une fosse. De plus, lorsque le sol est meuble, il est parfois impossible de réaliser de tels travaux de terrassement tout en assurant une parfaite étanchéité de la fosse.However, for large transformers, it is necessary to perform major earthworks and construction of a reinforced concrete pit significantly burdening the duration of work and their costs. The costs are even greater when the ground is rocky, the nature of the soil requiring large technical means to dig a pit. In addition, when the soil is loose, it is sometimes impossible to perform such earthwork while ensuring a perfect seal of the pit.

BREVE DESCRIPTION DE L'INVENTIONBRIEF DESCRIPTION OF THE INVENTION

L'un des buts de l'invention est donc de remédier à ces inconvénients en proposant un dispositif de sécurité pour la récupération de produits dangereux pouvant fuir d'un transformateur électrique, ledit dispositif comportant un capot dit de sécurité pour éviter que lesdits produits ne prennent feu et/ou pour éteindre les produits en feu lors de leur fuite, de conception simple, peu onéreuse, modulaire et pouvant être utilisé pour toute taille de transformateur.One of the aims of the invention is thus to remedy these drawbacks by proposing a safety device for the recovery of dangerous products that can leak from an electrical transformer, said device comprising a so-called safety cover to prevent said products from being damaged. fires and / or extinguish products on fire during their flight, simple design, inexpensive, modular and can be used for any transformer size.

Chaque bac présente une forme sensiblement parallélépipédique comportant une paroi de fond horizontale, deux parois transversales verticales et deux parois longitudinales verticales.Each tray has a substantially parallelepipedal shape comprising a horizontal bottom wall, two vertical transverse walls and two vertical longitudinal walls.

Les parois transversales de chaque bac font saillie au-delà des parois longitudinales pour former de chaque côté du bac des ailes de fixation, chaque aile de fixation comportant une pluralité de trous aptes à recevoir des boulons et des écrous.The transverse walls of each tray protrude beyond the longitudinal walls to form on each side of the tray fastening wings, each fixing wing having a plurality of holes adapted to receive bolts and nuts.

Par ailleurs, afin d'assurer l'étanchéité de la liaison entre deux bacs adjacents, le bord supérieur de l'une des parois transversales de chaque bac comporte un profilé en forme de U dont la concavité est orienté vers le bas, ledit profilé en U venant coiffé le bord supérieur de la paroi transversale du bac adjacent.Furthermore, in order to ensure the tightness of the connection between two adjacent bins, the upper edge of one of the transverse walls of each tray comprises a shaped section.

Accessoirement, chaque bac comporte une conduite dite de trop plein s'étendant depuis le fond du bac et débouchant le long d'au moins une de ses parois longitudinales, à proximité de son bord supérieur.Incidentally, each tank has a so-called overflow pipe extending from the bottom of the tank and opening along at least one of its longitudinal walls, near its upper edge.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

On décrira ci-après, à titre d'exemple non limitatif, un dispositif de sécurité destiné aux équipements pour réseaux de distribution de l'électricité et en particulier destiné à recueillir les huiles fuyant des transformateurs électriques ; Toutefois, il est bien évident que le dispositif de sécurité suivant l'invention pourra être aisément adapté à tout dispositif comportant des produits dangereux, à toutes les citernes de produits dangereux tels que des produits chimiques toxiques ou inflammables, ou similaire sans pour autant sortir du cadre de l'invention.The following will be described, by way of non-limiting example, a safety device for equipment for electricity distribution networks and in particular for collecting oils fleeing electrical transformers; However, it is obvious that the safety device according to the invention can easily be adapted to any device comprising dangerous products, to all the tanks of dangerous products such as toxic or flammable chemicals, or the like without leaving the framework of the invention.

En référence aux figures 1 à 5, le dispositif de sécurité suivant l'invention est constitué de trois bacs étanches 1, obtenus dans de l'acier inoxydable ou de l'acier galvanisé par exemple, joints deux à deux. Chaque bac 1 présente une forme sensiblement parallélépipédique et comporte une paroi de fond horizontale 2, deux parois transversales verticales 3 et deux parois longitudinales verticales 4. En référence à la figure 6, les parois transversales 3 de chaque bac 1 fait saillie au-delà des parois longitudinales 4 pour former de chaque côté du bac 1 des ailes de fixation 5, chaque aile de fixation 5 comportant une pluralité de trous 6 aptes à recevoir des boulons 7 et des écrous 8. Les ailes de fixation 5 munies de trous 6 recevant les boulons 7 et les écrous 8 forment des moyens de solidarisation des bacs entre eux.With reference to Figures 1 to 5 , the safety device according to the invention consists of three sealed tanks 1, obtained in stainless steel or galvanized steel for example, joined in pairs. Each tray 1 has a substantially parallelepipedal shape and comprises a horizontal bottom wall 2, two vertical transverse walls 3 and two vertical longitudinal walls 4. With reference to FIG. figure 6 , the transverse walls 3 of each tray 1 protrude beyond the longitudinal walls 4 to form on each side of the tray 1 of the attachment wings 5, each fixing wing 5 having a plurality of holes 6 adapted to receive bolts 7 and The fastening flanges 5 provided with holes 6 receiving the bolts 7 and the nuts 8 form means for securing the containers together.

Il va de soi que ces moyens de solidarisation pourraient être substitués par tous moyens de solidarisation équivalents bien connus de l'homme du métier sans pour autant sortir du cadre de l'invention.It goes without saying that these securing means could be substituted by any equivalent means of solidarization well known to those skilled in the art without departing from the scope of the invention.

En référence à la figure 7, le bord supérieur de l'une des parois transversales 3 de chaque bac 1 comporte un profilé en forme de U 9 dont la concavité est orienté vers le bas, ledit profilé en U 9 venant coiffer le bord supérieur de la paroi transversale 3 du bac 1 adjacent pour assurer l'étanchéité de la liaison entre lesdits bacs 1.With reference to the figure 7 , the upper edge of one of the transverse walls 3 of each tray 1 comprises a U-shaped profile 9 whose concavity is oriented downwards, said U-shaped section 9 capping the upper edge of the transverse wall 3 of the adjacent tray 1 to seal the connection between said bins 1.

Par ailleurs, en référence aux figures 1 à 4, le bac central 1 du dispositif comporte des moyens de support du transformateur électrique, non représentés sur les figures. Ces moyens de support consistent dans deux poutrelles métalliques 10 s'étendant transversalement à l'extrémité supérieure du bac central 1. L'écartement de ces poutrelles métalliques 10 de support est égal à l'écartement des pieds du transformateur électrique et la largeur de ces poutrelles est supérieure à la largeur de chaque pied du transformateur électrique. Ces poutrelles métalliques 10 sont solidarisées sur les parois longitudinales 4 par tous moyens appropriés tel que par soudage par exemple.Moreover, with reference to Figures 1 to 4 , the central tray 1 of the device comprises support means of the electrical transformer, not shown in the figures. These support means consist of two metal beams 10 extending transversely to the upper end of the central tray 1. The spacing of these metal support beams 10 is equal to the spacing of the feet of the electrical transformer and the width of these beams is greater than the width of each foot of the electrical transformer. These metal beams 10 are secured to the longitudinal walls 4 by any appropriate means such as welding for example.

De plus, en référence aux figures 1 à 6, chaque bac comporte le long de ses parois longitudinales 4, à proximité de son fond 2, au moins deux trous 11 aptes à recevoir une conduite coudée 12 pour mettre en communication deux bacs adjacents. Dans cet exemple particulier de réalisation lesdits trous 11 s'étendent l'un au dessus de l'autre et reçoivent respectivement une conduire coudée 12 flexible. Néanmoins, il est bien évident que les conduites flexibles 12 pourront être substituées par des conduites rigides. De plus, chaque bac 1 comporte une conduite dite de trop plein 13 s'étendant depuis le fond 2 du bac 1 et débouchant le long d'au moins une de ses parois longitudinales 3, à proximité de son bord supérieur.In addition, with reference to Figures 1 to 6 , each tray has along its longitudinal walls 4, near its bottom 2, at least two holes 11 adapted to receive a bent pipe 12 for communicating two adjacent tanks. In this particular embodiment, said holes 11 extend one above the other and respectively receive a bendable flexible conduit 12. Nevertheless, it is obvious that the flexible pipes 12 may be substituted by rigid pipes. In addition, each tray 1 comprises a so-called overflow pipe 13 extending from the bottom 2 of the tray 1 and opening along at least one of its longitudinal walls 3, near its upper edge.

On notera que le dispositif suivant l'invention permet ainsi de récupérer la totalité du volume des produits inflammables fuyant du transformateur électrique sans avoir à surélever exagérément le transformateur électrique, la totalité du volume de produits inflammables se répartissant dans les différents bacs 1. Ainsi, le nombre de bacs 1 utilisés dépendra de la taille du transformateur et in fine du volume de produits inflammables susceptibles de fuir.It will be noted that the device according to the invention thus makes it possible to recover the entire volume of flammable products leaking from the electrical transformer without having to overemphasize the electrical transformer, the entire volume of flammable products being distributed in the different tanks 1. Thus, the number of tanks 1 used will depend on the size of the transformer and ultimately the volume of flammable products likely to leak.

Par ailleurs, le dispositif suivant l'invention permet de répartir l'ensemble de la charge du transformateur électrique sur une grande surface de sorte qu'il est particulièrement adapté pour des transformateurs devant être installé sur des sols meubles.Furthermore, the device according to the invention makes it possible to distribute the entire load of the electrical transformer over a large area so that it is particularly suitable for transformers to be installed on soft floors.

Accessoirement, chaque bac comporte le long de l'une de ses parois longitudinales 3 au niveau de son fond 2 une vanne de vidange 14.Incidentally, each tray has along one of its longitudinal walls 3 at its bottom 2 a drain valve 14.

De manière particulièrement avantageuse, chaque bac 1 comporte à son extrémité supérieure un capot de sécurité 15 coiffant ledit bac 1 et constitué de lamelles transversales 16. le capot de sécurité 15 formant des moyens d'extinction consistent en un capot coiffant le bac 1 et comprenant des lamelles à pentes multiples 16 réservant entre elles un espace assurant aux produits coulants un accès au bac 1 tout en évitant une alimentation suffisante en oxygène pour permettre d'entretenir une combustion des huiles. Chaque lamelle 16 comporte de préférence deux pentes 16a et 16b pour l'écoulement du produit, et de préférence des pentes 16a, 16b de surfaces identiques séparées par une unique ligne de crête 17. De tels moyens d'extinction sont décrits par ailleurs en détail dans la demande de brevet WO 2009/016203 déposée par la Demanderesse qui est incorporée par référence.Particularly advantageously, each tray 1 comprises at its upper end a safety cap 15 covering said tray 1 and consisting of transverse strips 16. the safety cap 15 forming extinguishing means consist of a styling cap the tray 1 and comprising slats with multiple slopes 16 reserving between them a space ensuring the flowable products access to the tray 1 while avoiding a sufficient supply of oxygen to allow maintenance of a combustion of the oils. Each strip 16 preferably comprises two slopes 16a and 16b for the flow of the product, and preferably slopes 16a, 16b of identical surfaces separated by a single peak line 17. Such extinguishing means are described in detail in detail. in the patent application WO 2009/016203 filed by the Applicant which is incorporated by reference.

Il est bien évident que les moyens d'extinction formés par le capot de sécurité 15 pourront être substitués par tout autre moyen d'extinction tel que les moyens d'extinction décrits dans la demande de brevet français FR 0955356 déposée par la demanderesse et incorporée par référence.It is obvious that the extinguishing means formed by the safety cover 15 may be substituted by any other extinguishing means such as the extinguishing means described in the French patent application. FR 0955356 filed by the applicant and incorporated by reference.

Il va de soi que le dispositif suivant l'invention pourra ne comporter que deux bacs joints ensemble ou plus de trois bacs joints deux à deux en fonction de la taille du transformateur sous lequel le dispositif doit être placé, sans pour autant sortir du cadre de l'invention. Ainsi, le dispositif suivant l'invention est constitué d'au moins deux bacs étanches 1 comportant des moyens de solidarisation des bacs entre eux et des conduites aptes à mettre en communication lesdits bacs, au moins un bac 1 comportant des moyens de support du transformateur.It goes without saying that the device according to the invention may comprise only two tanks joined together or more than three bins joined in pairs depending on the size of the transformer under which the device must be placed, without departing from the scope of the invention. Thus, the device according to the invention consists of at least two sealed tanks 1 comprising means for securing the bins together and pipes able to put in communication said bins, at least one tray 1 having means for supporting the transformer .

Enfin, il est bien évident que les exemples que l'on vient de donner ne sont que des illustrations particulières, en aucun cas limitatives quant aux domaines d'application de l'invention.Finally, it is obvious that the examples which have just been given are only particular illustrations, in no way limiting as to the fields of application of the invention.
