Description

Anti-vibration and waterproof base for installation of electrical transformers.

Object of the invention

The present invention relates to a base anti-vibration and waterproof for the installation of transformers electrical in medium and high voltage transformer stations, which absorbs the vibrations produced by the transformer in order to prevent its spread, and the inconvenience that this implies to adjoining homes.

Another aspect of the invention lies in the provision of airtight means, to collect possible leaks of oil coming from the transformer, and drowning possible fires of the same.

Background of the invention

Currently in the construction of a new building, or rehabilitation of one exists, the companies of electrical supply require the installation of a station transformer to service the new construction. For it is necessary to enable a space, either an underground pit or well a cabin on the floor of the building, for the installation of an electrical transformer and all the equipment electrical required.

The construction of the underground pit or the cabin for the installation of the electric transformer requires a concrete and / or special foundation to house all the components that make up the transformer station. Specifically, the installation of the electric transformer itself, requires a special platform built in situ by civil works that allows the displacement, placement and installation of the same, as well as a pit for the collection of possible oil leaks from the electric transformer.

A drawback of this type of platform is that must be expressly built for the occasion, by work civil, which requires a complementary work and time that delays and complicates the commissioning of the station transformer

Another drawback is that being the platform built directly on the foundations of the building, it they transmit the vibrations of the transformer to the attached houses or adjoining, with the inconvenience that this represents for its population.

Description of the invention

The anti-vibration and waterproof base for installation of electrical transformers that the invention proposes, solves the problem described above, by having means to absorb vibrations, while having a watertight compartment for collecting possible leaks from oil.

To do this, and more specifically, the basis anti-vibration and waterproof for the installation of transformers electrical, includes a transportable platform equipped with a plurality of springs that contact the ground, to absorb the vibrations produced by the transformer, on whose platform has a metal deposit, likewise Geometric configuration than the platform. This deposit is provided, in its upper opening, with a grid on which a layer of stones is available to cover the deposit, and a pair of longitudinal guides for sliding and positioning the electric transformer on the tank.

The transportable platform is composed of a metal perimeter frame filled with reinforced concrete with interlocking metal rods, the arrangement of a plurality of inverted metal drawers that host two springs.

Inverted metal drawers have a threaded screw on its upper base to axially displace the spring, in order to raise the platform from the ground.

On the other hand, the metallic deposit has in its interior of at least six metal columns to support three transverse beams of double "T", on whose fins lower supports the grid that supports the layer of stones, which, in turn, support the pair of longitudinal guides for  sliding and positioning of the electric transformer on the Deposit.

To drain the accumulated oil in the tank, this is provided with a conduit that crosses the grid metallic and the layer of stones, which is provided with a lid practicable.

Description of the drawings

To complete the description that is being performing, and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1 shows an elevation of the base anti-vibration and waterproof, sectioned longitudinally, with the Electric transformer properly installed on the guides.

Figure 2 shows a plan view of the anti-vibration and waterproof base with the electric transformer properly installed.

Figure 3 shows a plan view of the platform, partially sectioned in which you can see the interlocking metal rods.

Figure 4 shows a longitudinal section of the previous view of the platform on which the arrangement of metal drawers and springs.

Figure 5 shows a perspective view of the platform without the concrete filling, on which you can appreciate the perimeter frame and the union of the metal rods and drawers.

Preferred Embodiment of the Invention

In view of the figures outlined you can be observed as the anti-vibration and waterproof base for installation of electrical transformers (1) comprises a transportable platform (2) equipped with a plurality of springs (3), specifically eight for the present embodiment, which contact the ground to absorb the vibrations produced by the electric transformer (1), on whose platform you have a metallic deposit (4), of the same geometric configuration as the platform (2), which we will explain later.

The platform (2) is composed of a frame metal perimeter (5) reinforced concrete filling (6) with rods cross-linked metal (7), among which there is a plurality of inverted metal drawers (8), specifically eight for the present embodiment, which house two springs (3). As can be seen in Figure 5, the interlocking metal rods (7) are welded at their ends to the perimeter frame (5), and the inverted metal drawers (8) go soldiers between the grids that make up the rods metallic (7). In this way, once the structure is configured Metal platform (2) is filled with concrete to obtain a  integral block

Inside the metal drawers (8) inverted, the springs (3) are disposed, properly dimensioned, which are provided with a threaded screw (9), which emerges from the top base of the drawer (8) for the axial displacement of the spring (3), in order to raise the platform Regarding the ground. In this way, once the platform is positioned at the transformer station, the screws are turned threads (9) to raise the platform (2) from the ground through the springs (3), which will absorb the vibrations produced by the transformer. Once the platform (2) is raised and leveled, the head of the threaded screws (9) is closed by a cover practicable.

On said platform (2) the metallic tank (4), of the same geometric configuration as the platform (2) for collecting oil from possible electrical transformer leaks (1). This deposit has in your interior of at least six metal columns (10) distributed in the corners and intermediate point of the longer walls, for the support of three crossbeams (11) in double section "T", on whose lower fins (12) are supported metal gratings (13) that support a layer of stones (14). On the transverse beams (11) there are two guides Longitudinal (15) for sliding and positioning the electric transformer (1) on the tank (4). The structure formed by columns (10), cross beams (11) and guides Longitudinal (15) support the weight of the transformer (1) on the deposit (4). Also, indicate that the layer of stones (14) supported by the metal grilles (13), allow the passage towards the deposit of possible oil leaks from the transform, while serving to drown the fire in case of fire oil stored in it.

To drain the accumulated oil in the tank (4) there is a conduit (16) that crosses the grid metallic (13) and layer of stones (14), which is equipped with a cover (17) practicable.

Another advantage of the anti-vibration and waterproof base object of the present invention is that since it is not jointly and severally fixed to the foundations of the transformer station or building, it you can disassemble and transport to another location for your reuse, in case the station is dismantled transformer where it is installed.
