Abstract
Description
Technical Field
[0001] This utility model relates to the field of transformer substation technology, and more specifically, to a low-voltage chamber transformer substation structure. Background Technology
[0002] Prefabricated substations are mainly used in various applications such as temporary power supply at construction sites, residential communities, and new energy power plants, and their advantages are particularly evident in scenarios with limited space. To better meet these needs, the design and manufacturing of prefabricated substations are continuously developing towards miniaturization and integration.
[0003] However, conventional prefabricated substations typically have a relatively square shape, which makes them relatively large in some situations, making it difficult to meet the usage requirements of specific sites. This is especially true for locations where strict space control is required, such as urban centers and areas surrounding high-rise buildings, where the application of conventional prefabricated substations is significantly limited. Utility Model Content
[0004] The purpose of this utility model is to provide a low-voltage box-type transformer structure that can solve the technical problem that existing square box-type transformers cannot be placed due to space limitations, thereby reducing the size and manufacturing cost.
[0005] The embodiments of this utility model can be implemented as follows:
[0006] In a first aspect, this utility model provides a low-voltage transformer substation structure, including a base plate and a transformer substation body disposed on the base plate. The transformer substation body includes a low-voltage chamber unit, a high-voltage chamber unit, and a transformer unit. The low-voltage chamber unit, the high-voltage chamber unit, and the transformer unit are arranged in a triangular pattern. The low-voltage chamber unit and the high-voltage chamber unit are arranged side by side on one side of the transformer unit.

[0028] Please refer to Figure 1 This utility model provides a low-voltage transformer substation structure 100, including a base plate 10 and a transformer substation body disposed on the base plate 10. The transformer substation body includes a low-voltage chamber unit 20, a high-voltage chamber unit 30, and a transformer unit 40. The low-voltage chamber unit 20, the high-voltage chamber unit 30, and the transformer unit 40 are arranged in a triangular pattern. The low-voltage chamber unit 20 and the high-voltage chamber unit 30 are arranged side by side on one side of the transformer unit 40. A first notch 26 is provided on the side of the low-voltage chamber unit 20 away from the transformer unit 40. The first notch 26 is located at the corner of the low-voltage chamber unit 20 away from the high-voltage chamber unit 30.
[0029] Understandably, in this embodiment, the low-voltage chamber unit 20 and the high-voltage chamber unit 30 are located within the enclosure. The enclosure is divided to form the low-voltage chamber unit 20 and the high-voltage chamber unit 30. Both the low-voltage chamber unit 20 and the high-voltage chamber unit 30 are surrounded by a partition. A first notch 26 is formed by an inward recess at one corner of the enclosure. The first notch 26 is used to avoid external environmental features, such as pillars, thereby allowing the low-voltage chamber transformer structure 100 to be placed.
[0030] Specifically, the low-pressure chamber unit 20 has a first panel 22 and a second panel 23 at the first notch 26. The low-pressure chamber unit 20 includes a first side 21 and a second side 24. The first side 21, the first panel 22, the second panel 23, and the second side 24 are connected vertically in sequence. It can be understood that the first notch 26 is provided with the first panel 22 and the second panel 23 as a surrounding plate to enclose the low-pressure chamber unit 20.
[0031] Furthermore, exhaust vents 25 are provided on the first panel 22 and the second panel 23. A fan is installed at the exhaust vent 25 for dissipating heat from the interior of the low-pressure chamber unit 20. Specifically, the low-pressure chamber unit 20 also has an air inlet. The air inlet is equipped with louvers. By driving the air flow through the fan, an air duct is formed between the air inlet and the exhaust vent 25, carrying away the heat dissipated by the internal components.
[0032] Furthermore, in order to increase the installation clearance of the low-voltage transformer substation structure 100, in this embodiment, an arc surface or a chamfered plane is provided between the first side 21 and the first panel 22, and between the second side 24 and the second panel 23.
[0033] Please refer to Figure 2 The base plate 10 has a second notch 16. The second notch 16 corresponds to the first notch 26.
[0034] Specifically, the base plate 10 is a frame structure formed by welding angle steel. The base plate 10 includes at least a first angle steel 11, a second angle steel 12, a third angle steel 13, and a fourth angle steel 14 connected vertically in sequence. The first angle steel 11 corresponds to the first side panel 21. The second angle steel 12 corresponds to the first panel 22. The third angle steel 13 corresponds to the second panel 23. The fourth angle steel 14 corresponds to the second side panel 24. It can be understood that the first angle steel 11 is located at the bottom of the first side panel 21 and is fixedly connected to the bottom of the first side panel 21. The second angle steel 12 is located at the bottom of the first panel 22 and is fixedly connected to the first panel 22. The third angle steel 13 is located at the bottom of the second panel 23 and is fixedly connected to the second panel 23. The fourth angle steel 14 is located at the bottom of the second side panel 24 and is fixedly connected to the second side panel 24. This makes the shape of the base plate 10 correspond to the shape of the low-pressure chamber unit 20.
[0035] Furthermore, to enhance the strength of the low-voltage room transformer substation structure 100, in this embodiment, a reinforcing rib 15 is connected between the second angle steel 12 and the third angle steel 13. Specifically, one end of the reinforcing rib 15 is connected to the end of the second angle steel 12 near the first angle steel 11. The other end of the reinforcing rib 15 is connected to the end of the third angle steel 13 near the fourth angle steel 14. Specifically, in this embodiment, the second angle steel 12, the third angle steel 13, and the reinforcing rib 15 are connected to form a triangular structure, enhancing the stability and strength of the low-voltage room transformer substation structure 100.
[0036] Please continue to refer to Figure 1 The low-voltage transformer substation structure 100 also includes a top plate 50. A third notch 54 corresponding to the first notch 26 is provided on the top plate 50.
[0037] Specifically, the top plate 50 includes a first top plate 51 and a second top plate 52 connected to each other. The first top plate 51 is disposed above the low-pressure chamber unit 20. The second top plate 52 is disposed above the high-pressure chamber unit 30. The height of the first top plate 51 gradually decreases along the direction from the low-pressure chamber unit 20 away from the high-pressure chamber unit 30. The height of the second top plate 52 gradually decreases along the direction from the high-pressure chamber unit 30 away from the low-pressure chamber unit 20. It can be understood that, in this embodiment, the first top plate 51 and the second top plate 52 are inclined downwards towards the outside of the housing, forming a herringbone structure, so that rainwater can flow down the surfaces of the first top plate 51 and the second top plate 52.
[0038] Furthermore, a drainage channel 53 is also provided on the top plate 50. Specifically, the drainage channel 53 is provided along the inclined direction of the first top plate 51 or the second top plate 52.
[0039] Furthermore, an operating corridor is also provided within the low-voltage chamber unit 20. Specifically, the operating corridor is arranged along the direction away from the transformer unit 40 in the low-voltage chamber unit 20, and corresponds to the first notch 26. It can be understood that, in this embodiment, by providing the first notch 26, the length of the operating corridor is reduced, thereby lowering the manufacturing cost of the low-voltage chamber transformer structure 100.
[0040] The beneficial effects of the low-voltage chamber transformer structure 100 provided in this embodiment of the utility model include:
[0041] The low-voltage transformer substation structure 100 of this utility model includes a base plate 10 and a transformer substation body disposed on the base plate 10. The transformer substation body includes a low-voltage chamber unit 20, a high-voltage chamber unit 30, and a transformer unit 40. The low-voltage chamber unit 20, the high-voltage chamber unit 30, and the transformer unit 40 are arranged in a triangular pattern. The low-voltage chamber unit 20 and the high-voltage chamber unit 30 are arranged side by side on one side of the transformer unit 40. A first notch 26 is provided on the side of the low-voltage chamber unit 20 away from the transformer. The first notch 26 is located at the corner of the side of the low-voltage chamber unit 20 away from the high-voltage chamber unit 30. By opening a first notch 26 on one side of the edge of the low-voltage chamber, this utility model changes the conventional square triangular arrangement of the low-voltage chamber transformer substation structure 100 into an irregular shape, which can be applied to environments with limited space, such as environments with columns, where the transformer substation does not need to be placed at an angle. This solves the technical problem that existing square transformer substations cannot be placed due to space limitations, reduces the external size, and lowers the manufacturing cost.
[0042] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
