Description
Technical Field
[0001] This utility model relates to the field of substation technology, and in particular to a prefabricated substation that is easy to load into containers. Background Technology
[0002] In existing prefabricated substations, there are no special restrictions on the size or type of transformers, medium-voltage switchgear, and low-voltage switchgear used. They are all set up in parallel without any special layout design. When packaged into container-type prefabricated substations for easy sea transport, the size of a single transformer reaches the standard of a 20-foot container, i.e., 6058 (length). 2438 (width) 2896mm (height). This is a high space utilization rate for large-capacity prefabricated substations, but a low space utilization rate for small-capacity prefabricated substations, resulting in wasted container space and increased transportation costs. More importantly, a 20-foot container occupies 14.7 square meters, which is too large to be used in all projects (some projects do not have such a large area reserved). Utility Model Content
[0003] To address the aforementioned shortcomings, the purpose of this utility model is to propose a prefabricated substation that is easy to load into containers, thus solving the problems of excessively large size of prefabricated substations, which are not conducive to container loading, resulting in wasted space, high transportation costs, and excessive area occupied during on-site installation.
[0004] To achieve this objective, the present invention adopts the following technical solution: A prefabricated substation that is easy to load into containers includes a square cube frame. The bottom surface of the square cube frame is provided with a support base. A T-shaped partition plate perpendicular to the support base is provided above the support base. The T-head horizontal plate of the T-shaped partition plate and the left part of the square cube frame form a transformer installation position. The T-tail vertical plate of the T-shaped partition plate and the right rear and right front parts of the square cube frame respectively form a low-voltage switchgear installation position and a medium-voltage switchgear installation position. A transformer, a low-voltage switchgear, and a medium-voltage switchgear are respectively installed in the transformer installation position, the low-voltage switchgear installation position, and the medium-voltage switchgear installation position. The length, width, and height of the square cube skeleton do not exceed 3m, 2.5m, and 3m, respectively.
[0005] Furthermore, the length, width, and height of the transformer do not exceed 2.3m, 1.1m, and 2.5m, respectively. The length, width, and height of the low-voltage switchgear shall not exceed 1.5m, 0.8m, and 2.2m, respectively. The length, width, and height of the medium-pressure switchgear shall not exceed 1m, 1m, and 2.2m, respectively.
[0006] Furthermore, a busbar trunking is provided on the top of the transformer, and the busbar trunking passes through the T-shaped partition plate to connect the transformer and the low-voltage switchgear.
[0007] Furthermore, a grille door and a grille encapsulation panel are installed on the side of the transformer mounting position along the square cube frame and the T-shaped partition plate; A grid encapsulation panel is installed on the top surface of the transformer mounting position along the square cube skeleton and the T-shaped partition plate.
[0008] Furthermore, a sealed door and a sealed enclosure panel are installed on the side of the low-voltage cabinet location along the square cube frame and the T-shaped partition plate. A sealed enclosure panel is installed on the top surface of the low-voltage cabinet along the square cube frame and the T-shaped partition plate.
[0009] Furthermore, a sealed door and a sealed enclosure panel are installed on the side of the medium-voltage cabinet location along the square cube frame and the T-shaped partition plate. A sealed enclosure panel is installed on the top surface of the medium-voltage cabinet along the square cube frame and the T-shaped partition plate.
[0010] Furthermore, the support base is provided with multiple reinforcing ribs, which are arranged across the bottom frame of the square cube frame, and the multiple reinforcing ribs are connected in an interlaced manner.
[0011] The technical solution provided by this utility model can include the following beneficial effects: the overall size of the prefabricated substation is limited by the square cube frame with defined length, width and height, so that it meets the 10-foot container standard, which facilitates container loading, reduces space waste and transportation costs, and reduces the floor area, basically adapting to the needs of all projects.
[0012] Based on this, the internal space of the square cubic frame is rationally divided using T-shaped partitions 3 perpendicular to the supporting base, changing the traditional parallel arrangement of transformers, medium-voltage switchgear, and low-voltage switchgear, thus adapting to the 10-foot container standard. More importantly, after using the T-shaped partitions to divide the space into sufficient lengths for transformer installation (because the size difference between large and small capacity transformers is mainly reflected in length, which is not easy to reduce, leading to the core reason for adopting the 20-foot container standard), the remaining internal space of the square cubic frame is then flexibly divided into low-voltage switchgear and medium-voltage switchgear installation positions (the size of the switchgear is easy to adjust). This allows prefabricated substations of both large and small capacity to compactly integrate the three main components of a substation within the 10-foot container standard.

[0021] The following is combined with Figures 1 to 3 This invention describes a prefabricated substation that is easy to load into containers, according to an embodiment of the present invention.
[0022] A prefabricated substation that is easy to load into containers includes a square cube frame 1. The bottom surface of the square cube frame 1 is provided with a support base 2. A T-shaped partition plate 3 perpendicular to the support base 2 is provided above the support base 2. The T-head horizontal plate of the T-shaped partition plate 3 and the left part of the square cube frame 1 enclose a transformer installation position 4. The T-tail vertical plate of the T-shaped partition plate 3 and the right rear and right front parts of the square cube frame 1 respectively enclose a low-voltage switchgear installation position 5 and a medium-voltage switchgear installation position 6. A transformer, a low-voltage switchgear, and a medium-voltage switchgear are respectively installed in the transformer installation position 4, the low-voltage switchgear installation position 5, and the medium-voltage switchgear installation position 6. The length, width, and height of the square cube skeleton 1 shall not exceed 3m, 2.5m, and 3m, respectively.
[0023] This utility model proposes a preferred embodiment of a prefabricated substation that is easy to load into containers, such as... Figure 1 As shown, the overall size of the prefabricated substation is limited by a square cube frame 1 with defined length, width, and height, making it conform to the 10-foot container standard. This facilitates container loading, reduces space waste and transportation costs, and minimizes the floor space required, thus basically meeting the needs of all projects.
[0024] Based on this, the internal space of the square cubic frame 1 is rationally divided using a T-shaped partition plate 3 perpendicular to the support base 2, changing the traditional parallel arrangement of transformers, medium-voltage switchgear, and low-voltage switchgear, thus adapting to the 10-foot container standard. More importantly, after using the T-head horizontal plate of the T-shaped partition plate 3 to divide a sufficiently long space for transformer placement 4 (because the size difference between large and small capacity transformers is mainly reflected in length, which is not easy to reduce, leading to the core reason for adopting the 20-foot container standard), the remaining internal space of the square cubic frame 1 is flexibly divided into low-voltage switchgear placement 5 and medium-voltage switchgear placement 6 (the size of the switchgear is easy to adjust), so that regardless of the size of the prefabricated substation, the three main components of the substation can be compactly integrated within the 10-foot container standard range.
[0025] Furthermore, the length, width, and height of the transformer shall not exceed 2.3m, 1.1m, and 2.5m, respectively; The length, width, and height of the low-voltage switchgear shall not exceed 1.5m, 0.8m, and 2.2m, respectively. The length, width, and height of the medium-voltage switchgear shall not exceed 1m, 1m, and 2.2m, respectively.
[0026] In this embodiment, based on the size limitation of the square cubic frame 1, the size selection of the transformer, low-voltage cabinet and medium-voltage cabinet installed at transformer installation position 4, low-voltage cabinet installation position 5 and medium-voltage cabinet installation position 6 is further limited. Based on this, T-shaped partition plates are set to separate them. Then, transformer installation position 4, low-voltage cabinet installation position 5 and medium-voltage cabinet installation position 6 will have redundant space for wiring and heat dissipation. When the prefabricated substation is installed, it can start working directly without the need for relocation.
[0027] It should be noted that the above size limits for transformers, low-voltage switchgear, and medium-voltage switchgear are derived from a summary of existing product sizes. Currently, most products on the market are slightly smaller than the specified sizes.
[0028] Furthermore, a busbar 41 is provided on the top of the transformer, and the busbar 41 passes through the T-shaped partition plate 3 to connect the transformer and the low-voltage switchgear.
[0029] In this embodiment, the substation typically distributes power externally after being electrically connected to the low-voltage switchgear. Therefore, a busbar 41 can be installed on top of the transformer to fix and connect the transformer and the low-voltage switchgear (because the transformer and the low-voltage switchgear are arranged back-to-back and close together, the busbar 41 can be, for example...). Figure 1 As shown in the diagram, an L-shaped cable tray is used for busbar connection; therefore, prefabricated substations do not require further wiring during installation, increasing the degree of prefabrication. Additionally, transformers and medium-voltage switchgear require external cables, and since the cables have a large diameter, prefabrication is not considered.
[0030] Furthermore, a grille door and a grille encapsulation panel are installed on the side of the transformer mounting position 4 along the square cube frame 1 and the T-shaped partition plate 3. A grid encapsulation panel is installed on the top surface of transformer mounting position 4 along the square cube skeleton 1 and T-shaped partition plate 3.
[0031] In this embodiment, as Figure 2 As shown, based on the fact that the transformer has a large heat dissipation requirement and generates a lot of heat when it is working, the top and side surfaces of the transformer installation position 4 are preferably encapsulated with a grid panel to facilitate anti-theft and protection after installation, and the grid door encapsulation facilitates opening the door for wiring, maintenance, and relocation.
[0032] Furthermore, a sealed door and a sealed enclosure panel are installed on the side of the low-voltage switchgear 5 along the square cube frame 1 and the T-shaped partition plate 3. A sealed enclosure panel is installed on the top surface of the low-voltage cabinet setting position 5 along the square cube frame 1 and the T-shaped partition plate 3.
[0033] Furthermore, the side of the medium-voltage switchgear 6 is equipped with a sealed door and a sealed enclosure panel along the square cube frame 1 and the T-shaped partition plate 3. A sealed enclosure panel is installed on the top surface of the medium-voltage cabinet setting position 6 along the square cubic frame 1 and the T-shaped partition plate 3.
[0034] In this embodiment, based on the requirements of anti-theft and protection, as well as their relatively small heat dissipation requirements, the low-voltage cabinet and the medium-voltage cabinet are preferably enclosed by sealed panels to cover the low-voltage cabinet mounting position 5 and the medium-voltage cabinet mounting position 6; at the same time, sealed doors should also be provided for opening the doors for wiring, maintenance, and relocation.
[0035] Furthermore, the support base 2 is provided with multiple reinforcing ribs 21, which are arranged across the bottom frame of the square cube frame 1, and the multiple reinforcing ribs 21 are connected in an interlaced manner.
[0036] In this embodiment, as Figure 3 As shown, the support base 2 of the prefabricated substation needs to support the transformer, low-voltage switchgear and medium-voltage switchgear, which is quite heavy. Therefore, the support base 2 needs to be equipped with crisscrossing reinforcing ribs to enhance the structural strength and load-bearing capacity of the support base 2; and during transportation and installation, it can effectively resist vibration and impact and avoid deformation of the support base 2.
[0037] It should be noted that there are several ways to arrange the reinforcing ribs 21 in a crisscross pattern. Multiple reinforcing ribs 21 can be arranged side-by-side from left to right, or side-by-side from front to back, and then interlocked; or as... Figure 3 As shown, the reinforcing ribs 21 are locally staggered.
