Description

Rack and gutter for electrical wiring.

Object of the invention

The present invention, as expressed in the set forth in this specification, refers to a casket and gutter for electrical wiring, which have been conceived and made for the passage, guidance and separation of high cables voltage with respect to the control and maneuver cables, in their access and arrangement on the casket itself.

The object of the invention is to prevent the wiring manipulative operators can, without pretending, act or touch a high voltage cable that is passing through the casket together with control and maneuver cables.

The cassette and gutter are preferably intended for application in the food service electric on railway tracks, where the casket is enclosed, although its application can be extended to other fields and / or sectors in which its use is possible and necessary.

Background of the invention

Currently, the power wiring electric to service railways, usually run through established boxes next to the track, usually  buried, to avoid any type of accident.

Now, these boxes access both the high voltage wiring such as command and maneuver wiring, distinguishing some cables from others by their color and even for its thickness.

Well, sometimes it can happen that by mistake, carelessness or any other circumstance, the operators that manipulate the control cables and maneuver touch without pretending a high voltage cable, with the consequent risk of accident, and this as a consequence of said high voltage cables and of command and maneuver run together without independence or separation between them. It is clear that it is desirable that high voltage cables run in a hidden and separate way regarding the control and maneuver cables.

Description of the invention

The casket and gutter object of the invention they have particular characteristics based on which high voltage cables run in a guided and isolated way with respect to the control and maneuver cables, thereby avoiding that the operators in charge of handling them can touch or act on high voltage cables, unless wish or have to do it after the relevant shots of Caution and / or safety.

In that sense, the casket of the invention, being constituted in concrete with internal reinforcement and being of general prismatic configuration, has the peculiarity that the access and / or output of the high voltage cables to it, is made through paths of fairings established in the interior, in correspondence with two walls, preferably opposite, those fairings being inferiorly communicated with each other through a tunnel established at the bottom or base of the own casket

These fairings communicate abroad to through paths lateral and superior openings of the casket, from whose openings respective outer grooved sections emerge in which they connect and connect respective gutters by which the cables run.

The two corrugated sections provided in the upper side openings of the case, have a partition longitudinal offset from the center, which gives rise to two channels, one of smaller width and destined to the passage and guided of the cables of high voltage, while the other channel is smaller and is provided for control and maneuver cables.

These two channels face each other two analogues established in the same way in the gutter that connects and attaches to the grooved sections derived from the casket, forming between them a continuity for the positioning and guidance of high voltage and control cables and maneuver, respectively.

The gutter channels close together with an upper cover that in turn covers and is above a cover that closes the channel of smaller width by the that the high voltage cables run. Each cover of the referred support on steps or longitudinal seats provided to the effect on the upper edge of the side walls of the gutter, or in one of these and in the partition that delimits the channels

As for the running of the control cables and maneuver through the box, they do it outside the fairings and the tunnel, that is, independently and visible with respect to the high voltage cables that run from Hidden way to avoid unwanted contact.

Finally say that the casket is also affected by holes for the passage of control and maneuver cables,  holes that are intended to allow the change of direction of the cited cables as it passes through the casket itself.

Brief description of the drawings

To complement the description that then it will be done and in order to help a better understanding of the features of the invention, accompanies the present descriptive memory a set of drawings based on the which innovations and advantages will be more easily understood of the cassette and gutter for the passage of electrical wiring, made in accordance with the object of the invention.

Description of the preferred embodiment

As you can see in the referred figures, the casket 1 of the invention is constituted by a prismatic body  rectangular materialized in concrete with its armor, in two of whose opposite side walls have planned openings superior 2, and faced with these, occupying a part of their amplitude, two internal fairings 3 that communicate inferiorly to each other through a tunnel 4, so that the High voltage cables access and / or exit through openings 2, running through fairings 3 and tunnel 4 of communication of them.

The rest of the amplitude of the openings 2 of the sides of the box 1 constitute the access and / or exit for control and maneuver cables.

In correspondence with those openings 2 have provided for two ribbed sections 5 with a longitudinal partition 6 outdated center, which originates two channels 7 and 8, this being last of greater height and planned for the passage of the cables of command and maneuver, while channel 7 of smaller width is provided for the passage of high voltage cables.

On those stretched sections 5 are coupled and They connect respective channels 9 equipped with a partition longitudinal 10 offset of the center, which gives rise to two channels 11 and 12 whose amplitude corresponds to that of channels 7 and 8 of the ribbed sections 5, so that through channel 11 of the 9 gutters will run the high voltage cables while the control cables and through the larger channel 12 will run maneuver.

Channel 11 of each channel 9 closes by an upper cover 13 resting on a step established in the inner part of the wall corresponding to the gutter 9 and in the partition 10 itself, while above that lid 13 has been provided a second cover 14 that covers the entire gutter 9, supporting in respective steps established on the inner side of the two longitudinal side walls of such gutter 9, as left see clearly in figure 1.

In this way, high voltage cables they always run independently and hidden from the control and maneuver cables, since through channel 9 they go through narrow channels 11 and control and maneuver cables by the wide channels 12, as happens in the sections fluted 5 where high voltage cables follow channels 7 of smaller width and the control and maneuver cables channels 8 of wider width, accessing the inside of the box 1 through the side openings 2, so that the high voltage cables access fairings 3 directly and run under the tunnel lower 4, while the control and maneuver cables access through the rest of the openings 2 outside the fairings 3 to run inside the box 1 itself but totally independent and insulated with respect to high voltage cables that run, as has been said, by fairings 3 and tunnel 4, is say in a hidden way, which prevents any operator who handle the control and maneuver cables can come into contact With high voltage cables.

Finally, say that in the box they have provided holes 15 that allow the change of direction of the control and maneuver cables that access and run inside of the casket itself 1.
