Abstract

The invention relates to a modular unit made up of at least one lower module, one intermediate module and one upper module, where each module in turn comprises a motherboard, side openings for connection or linking with other adjacently arranged modules, which can be covered with a set of covers, using a side linking part between modules; in addition the modules (10) comprise an upper and lower linking means suitable for linking with other modules or with an upper or lower sealing cover. The modules are made up of stackable parts, thus reducing storage and transport space, as well as allowing the configuration of as large a centralisation of meters as required, since the system supports horizontal and vertical expansion (15).

Description

MODULAR ASSEMBLY FOR APARTMENT AND CENTRALIZATION OF

COUNTERS

DESCRIPTION

OBJECT OF THE INVENTION It is an object of the present invention as the title of the invention itself establishes, a modular assembly intended to accommodate low voltage switchgear and counters, that is, the modular assembly allows centralizing the counters of different supplies in one place. electrical (residential buildings, commercial premises, etc). The set comes to create a type of modular cabinet with its corresponding corresponding doors according to the needs.

The present invention characterizes the special configuration and design of the parts and pieces that make up the modular assembly, so that they allow to achieve, in addition to the functionalities of a meter centralization, that the different parts or pieces can be manufactured and distributed separately for subsequent mounting on site. This fact reduces the volume of the modular assembly when storing and transporting. The design of all its parts allows us to use new recyclable, reusable and lighter plastic materials, obtained by injection at the time of its manufacture, this being a safer working system than the compression with presses used with polyester, which is generally used mostly for the manufacture of parts of this type. In addition, it is also possible to form columns of centralization of counters as wide as desired, and can be expanded in both directions, both vertically and horizontally, and can even be intercommunicated with each other. Therefore, the present invention is circumscribed within the scope of the cabinets or modules used in the conformation of the meter centralizations, which allow to house the different counters of a building, as well as the associated switchgear, that is, busbars, bomas, fuses, etc.

BACKGROUND OF THE INVENTION

The modules for the centralization of counters are well known in the state of the art. There are different existing manufacturers and each manufactures with its own characteristics adjusted to their own standards or practices.

In general, the existing modules for the realization of meter centralizations are multiple, with three basic types of modules, a busbar module, another meter module and a third busbar module and connecting bolts.

These modular elements are arranged stacked forming columns, their lateral expansion not being possible. They are also manufactured as a whole, except for a piece such as the front, which means that the modules occupy quite a lot of volume independently, this being an inconvenience for storage and subsequent distribution.

Therefore, it is the object of the present invention to develop a modular set for switchgear and centralization of counters that overcome the above drawbacks, that is to say that its expansion is not limited horizontally or vertically, as well as that the different modules that comprise it are manufactured so that they occupy the smallest possible volume, and are intercommunicated.

DESCRIPTION OF THE INVENTION

The invention of a modular assembly for switchgear and centralization of meters basically consists of three types of modules (depending on the size of the counters or their number may be made in different sizes):

- lower busbar module

- intermediate module for wiring and counters and

- end module for busbars and connecting bolts, where the whole assembly is closed inferiorly by means of a lower closing cover, while at the top, it is covered by an upper closing cover. Between adjacent modules there is a separation plate between modules, also presenting lateral link pieces between modules.

In addition, the intermediate module or modules have, on their own structure, a recess where a side link window cover can be accommodated between modules of small dimensions for certain cables, such as ground cables, etc.

In order to favor the union between the different modules, these have in their lower and upper part with ends designed so that they fit on the upper or lower part of the immediate module, and if it were the last module, on these ends the lower and upper closure lid.

The modules are made up of a base plate and a closing cover. The bodies of the modules, are formed by a bottom pocket or base plate, on which a grill can be fixed, then on it a meter holding plate, on which the counters are arranged and finally on This is a cover. In order to facilitate the fastening of each of the modules, these have a perforated side ears in their center through which some screws can be passed to fix to the wall. Thanks to the configuration described in which each of the modules is removable and formed by a base plate and a transparent cover, where the lower busbar module and the busbar upper and connecting bolts also have a lower or upper cover, side covers, as well as a separation plate between the intermediate modules and with covers of the side link windows, managing to reduce the volume when storing or transporting the pieces that form the future boxes, also it is possible to form centralization columns very wide, allowing its expansion both laterally and vertically, and also allows the interconnection between adjacent modules, whether arranged above or below or laterally attached.

Figures 10, 1 1 and 12 show different representations of the pocket (15) or base plate of the intermediate module (1), in which it is possible to review the ears (26) that it presents on its lateral sides so that they can be fixed to walls and walls this module. These ears (26) are also found in the lower modules (1) for busbars, and in the upper module (3) for busbars and bumpers.

Figures 13 and 14 show the perforated clamping areas (27) for fixing the tie plate (7) to the pocket or base plate (15) of an intermediate module (1).

In figures 15 and 16 it can be seen how the lower closing cover (4) has a series of ears (28) for mooring this cover (4), where in addition the cover (4) laterally has holes (17) for fitting of the ends or projections (12) of the base plate of a lower module (1).

In Figures 17 and 18 it is shown how the upper closing cover (5) has laterally recesses (18) in which the upper ends (13) of the base plate of an upper module (3) fit. Also on the cover (5) there are pre-cut areas (29) prepared to be removed from the cover (5) if necessary, for the corresponding wiring.

Figures 19, 20 and 21 show the separation and reinforcement pieces (6) between modules arranged vertically, where the presence of ears (30) for fixing the pieces (6) is noteworthy. Figures 22, 23 and 24 show different views of a cover or transparent revolving door (8) that can be sealed to the modules and that have pins (31) as hinges, allowing access to the interior of the module without having to remove the cover completely.

It does not alter the essentiality of this invention variations in materials, shape, size and arrangement of the component elements, described in a non-limiting manner, this being sufficient for reproduction by an expert.
