Description

Technical Field

[0001] The utility model relates to the field of box-type transformers, in particular to a prefabricated box-type transformer foundation. Background Art

[0002] A box-type substation is a high-voltage switchgear, a distribution transformer and a low-voltage distribution device, which are factory prefabricated indoor and outdoor compact distribution equipment arranged according to a certain wiring scheme, that is, functions such as transformer step-down and low-voltage distribution are organically combined together and installed in a moisture-proof, rust-proof, dust-proof, mouse-proof, fire-proof, anti-theft, heat-insulated, fully enclosed and movable steel structure box. It is especially suitable for urban network construction and transformation and is a brand-new substation that has emerged after civil substations. Box-type substations are applicable to mines, factories and enterprises, oil and gas fields and wind power stations. It replaces the original civil distribution rooms and substations and becomes a new type of complete set of power transformation and distribution devices. When installing a box-type substation, it should be installed on a cement foundation. Therefore, the box-type substation foundation should meet the requirements of economy, convenient construction and installation, and environmental protection.

[0003] Currently, box-type substations are generally fabricated on-site by masonry and in-situ casting, which requires a large amount of manpower, material resources and corresponding material curing time, has a long construction period, and is prone to the situation where the foundation does not match the box-type substation, making it difficult to install and resulting in rework, wasting manpower and material resources.

[0004] For the above reasons, this design proposes a prefabricated box-type transformer foundation. Summary of the Invention

[0005] The purpose of the utility model is to provide a prefabricated box-type transformer foundation.

[0006] To achieve the above purpose, the utility model is realized through such a technical solution. A prefabricated box-type transformer foundation includes a base plate. The base plate is rectangular. A plurality of columns are arranged at the lower end of the base plate to support the base plate. A box-type transformer installation groove and an accident oil pool are respectively arranged at the upper end of the base plate. The accident oil pool is distributed on the side of the box-type transformer installation groove. A plurality of installation holes are evenly distributed at the edges of the box-type transformer installation groove and the accident oil pool, and the upper part of the installation hole is wide and the lower part is narrow.

[0007] Furthermore, a staircase is connected and arranged at the left end of the base plate. A camera column installation protrusion is arranged at the lower right corner of the base plate. The camera column installation protrusion is conical. A through hole is arranged downward at the top of the camera column installation protrusion, and the camera cable extends to the lower side of the base plate through the through hole.

[0008] Advantageous Effects:

[0009] Compared with traditional box-type substations, it can effectively shorten the construction period and enable mass production. Moreover, it can be conveniently transported through assembly, and is not sensitive to on-site construction conditions through prefabrication, being unrestricted by the site and weather. In contrast, traditional cast-in-place box-type substations are restricted by the site and cannot be constructed in traditional mountainous areas and on water surfaces. However, the present utility model overcomes such defects. Additionally, by setting the installation holes to be wider at the top and narrower at the bottom, it becomes easier to match the box-type substation with the box substation installation groove, thus making the installation faster. Also, by prefabricating camera column installation protrusions on the substrate, subsequent cumbersome processes such as drilling holes in the substrate are eliminated, reducing damage to the overall structure of the substrate.

[0014] The following further clearly and completely describes the present utility model in conjunction with the accompanying drawings of the specification, but the protection scope of the present utility model is not limited thereto. Embodiment

[0015] As Figures 1 to 3 shown, a prefabricated box substation foundation includes a substrate 1, the substrate 1 is rectangular, several columns are provided at the lower end of the substrate 1 to support the substrate 1, a box substation installation groove 3 and an accident oil pool 4 are respectively provided at the upper end of the substrate 1, the accident oil pool 4 is distributed on the side of the box substation installation groove 3, several installation holes 5 are evenly distributed at the edges of the box substation installation groove 3 and the accident oil pool 4, and the upper part of the installation hole 5 is wider and the lower part is narrower.

[0016] In this embodiment, a stair 6 is further connected to the left end of the substrate 1, a camera column installation protrusion 7 is provided at the lower right corner of the substrate 1, the camera column installation protrusion 7 is conical, and a through hole 8 is provided downward from the top of the camera column installation protrusion 7, and the camera cable extends to the lower side of the substrate 1 through the through hole 8.

[0017] Working principle:

[0018] In the present utility model, the substrate 1, the box transformer installation grooves 3, the accident oil pool 4 and the columns 2 arranged above and below the substrate 1 are precast with concrete. Through factory prefabrication, they are directly transported to the site for assembly. Compared with traditional box transformers, the construction period can be effectively shortened and mass production can be achieved. Moreover, through assembly, transportation is convenient, and prefabrication is not sensitive to on-site construction conditions and is not restricted by the site and weather. Traditional cast-in-place box transformers are restricted by the site and cannot be constructed in traditional mountainous areas and on water surfaces. However, the present utility model overcomes this defect. In addition, in the present utility model, the installation holes 5 are set to be wider at the top and narrower at the bottom, making it easier to match the box-type substation with the box transformer installation grooves 3, thus making the installation faster. Furthermore, by prefabricating the camera column installation protrusions 7 on the substrate 1, subsequent cumbersome processes such as drilling holes in the substrate 1 are eliminated, reducing the damage to the overall structure of the substrate 1.
