Description

Technical Field

[0001] This utility model relates to the field of prefabricated substations, specifically to a heat-dissipating prefabricated substation. Background Technology

[0002] A prefabricated substation, also known as a prefabricated transformer substation, is a factory-prefabricated, compact indoor or outdoor power distribution device that integrates high-voltage switchgear, distribution transformers, and low-voltage power distribution equipment according to a specific wiring scheme. It organically combines the functions of transformer voltage reduction and low-voltage power distribution, and installs them in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, theft-proof, heat-insulated, fully enclosed, and movable steel structure box.

[0003] In existing prefabricated substations, the installation process typically involves first constructing a concrete foundation on the ground, reserving cable channels, and then hoisting the prefabricated transformer onto the concrete foundation and securing it with anchor bolts and other connectors. However, in actual use, there are often situations where prefabricated transformers need to be temporarily placed on concrete floors. Temporary placement with concrete foundations is costly and can damage the concrete floor, making repairs quite troublesome.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] To improve or solve the technical problem of high cost associated with temporary placement of prefabricated transformers and the construction of concrete foundations in existing technologies, this utility model provides a heat-dissipating prefabricated substation. The prefabricated substation includes: a transformer body, comprising a casing and electronic equipment installed inside the casing; louvers arranged on the casing; bases installed at the bottom of the casing and arranged in multiple circumferentially along the casing; the bases forming a detachable connection with the casing; and rodent-proof plates detachably installed between adjacent bases, with heat dissipation grooves formed on the rodent-proof plates.

[0006] This utility model discloses a heat-dissipating prefabricated substation, comprising a transformer body and a base. The transformer body includes a housing and electronic equipment. The housing is equipped with louvers to allow air circulation between the inside and outside, facilitating the exchange of hot air inside the housing with cool outside air. The base is installed at the bottom of the housing, allowing the housing to be suspended and facilitating cable routing. The base is detachably connected to the housing, allowing for temporary installation when needed, and stable installation on a concrete foundation. Rodent-proof panels are placed between adjacent bases to prevent small animals from entering the bottom of the housing and damaging cables. The rodent-proof panels have ventilation slots that allow hot air inside the housing to seep into the bottom and escape to the outside, enhancing the heat dissipation performance of the prefabricated substation. With these features, this heat-dissipating prefabricated substation can be conveniently and temporarily installed on a concrete floor, offering ease of use, low cost, and excellent heat dissipation performance thanks to the louvers and ventilation slots.

[0007] Furthermore, the base has a first end close to the housing and a second end away from the housing, and a connecting plate that is bolted to the housing is provided at the first end.

[0008] Furthermore, the size of the second end is larger than the size of the first end.

[0009] Furthermore, a limiting seat is provided on the base, and the limiting seat and the base form a receiving groove that matches the rodent-proof plate; bolt holes are also provided on the base, and one side of the rodent-proof plate is detachably connected to the base by bolts.

[0010] Furthermore, the enclosure includes a front wall, a rear wall arranged opposite to the front wall, and a side wall connecting the front wall and the rear wall; a closed door is arranged on the front wall, and the louvers are installed on the rear wall and the side wall.

[0011] Furthermore, a first partition and a second partition are arranged inside the box, and the first partition and the second partition are arranged in a hollowed-out manner.

[0012] In summary, compared with the prior art, this utility model has the following beneficial effects: (1) The enclosure is equipped with louvers to allow air circulation inside and outside the enclosure, thus facilitating the exchange of hot air inside the enclosure with cold air outside; the rodent-proof plate is provided with heat dissipation grooves to facilitate the hot air inside the enclosure to seep into the bottom of the enclosure and then flow out to the outside, thereby enhancing the heat dissipation performance of the box-type transformer. (2) The base is installed at the bottom of the box, which allows the box to be suspended and makes it easy for the cable to pass through the bottom of the box; the base and the box form a detachable connection, which can be installed at the bottom of the box when temporary arrangement is required, which facilitates the temporary arrangement of the box-type transformer; when it needs to be arranged on a cement foundation, the base is installed to facilitate the stable arrangement of the box-type transformer.
