[0030] See Figures 1 to 6 This utility model provides a novel split-type prefabricated substation, comprising: three independent compartments: a high-voltage compartment 1, a low-voltage compartment 2, and a transformer compartment 3; a parallel cabinet strip 4; an L-shaped upturned retaining edge 5; and a connecting assembly 6. The high-voltage compartment 1 and the low-voltage compartment 2 are installed on the left and right sides of the transformer compartment 3. Each of the high-voltage compartment 1, the low-voltage compartment 2, and the transformer compartment 3 is equipped with an independent outer enclosure. Conventional integrated prefabricated substations also have an outer enclosure, which is located on the outermost side to improve the protection level of the product. In this embodiment, the outer enclosure of the split-type prefabricated substation is similar in materials and structure to that of conventional outer enclosures, except that it is divided into three independent parts, each located outside the independent compartment; this will not be described in detail here.

[0031] See Figure 5 The bottom of the transformer chamber 3 is provided with four detachable plates 31; the detachable plates 31 are made of galvanized steel plate material, and the shape is not unique, so it is convenient to observe the inside of the square hole of the detachable plate 31. In this embodiment, a rectangle is preferred.

[0032] See Figure 4 , Figure 6The L-shaped flip-up baffle 5 is set on the edge of the top cover and cabinet end face of the three independent compartments; the cabinet strip 4 includes a top cabinet strip 41 and front and rear cabinet strips 42; wherein, the top cabinet strip 41 is installed on the top of the L-shaped flip-up baffle 5, and the front and rear cabinet strips 42 are set at the splicing point of each outer box; the three independent compartments and the outer box are provided with cabinet holes 7 at preset positions, and the connecting component 6 connects the three independent compartments and the outer box through the cabinet holes 7.

[0033] In this embodiment, the connecting component 6 includes: front and rear column bolt assemblies, a middle column bolt assembly, and a channel steel bolt assembly 61 located at the connection point of the three independent compartments; a cabinet-joining strip bolt assembly located at the top of the three independent compartments; an L-shaped upturned edge bolt assembly 62 located at the top cover and cabinet-joining surface of the three independent compartments; an outer box cabinet-joining strip bolt assembly located at the cabinet-joining surface of the three outer boxes; and an outer box channel steel bolt assembly located at the base of the cabinet-joining surface of the three outer boxes (the remaining components are not shown in the figure). The connecting component 6 is composed of bolts, nuts, flat washers, spring washers, and other components. The nuts in the channel steel bolt assembly 61 and the outer box channel steel bolt assembly are pre-welded to the inside of the side wall of the channel steel base of the high and low pressure chambers to improve the cabinet-joining efficiency on site.

[0034] See Figures 1 to 3 The high-voltage chamber 1, the low-voltage chamber 2, the transformer chamber 3, and the outer enclosure are connected by a first paralleling hole 71 on the inner side of the base channel steel. The detachable plate 31 is located on the top of the base channel steel. The detachable plate 31 is removed, and the channel steel bolt assembly 61 passes through the first paralleling hole 71 in the three independent compartments to connect the three independent compartments. The outer enclosure channel steel bolt assembly passes through the first paralleling hole 71 in the outer enclosure to fasten the outer enclosure.

[0035] See Figures 1 to 3 Each of the three independent compartments is provided with a central column 8 and front and rear columns 9 on the side of the cabinet. The central column 8 and the front and rear columns 9 have a second cabinet-joining hole 72. The second cabinet-joining hole 72 of the front and rear columns 9 is preferably an elongated hole. The second cabinet-joining hole 72 of the central column 8 is preferably a round hole. The central column bolt assembly passes through the second cabinet-joining hole 72 of the central column and the front and rear column bolt assembly passes through the second cabinet-joining hole 72 of the front and rear columns, connecting the three independent compartments and the outer casing.

[0036] See Figures 1 to 3 A reinforcing plate 721 is welded inside the second parallel cabinet hole; the thickness of the reinforcing plate 721 is preferably ≥3mm to prevent the bolt preload from causing deformation of the second parallel cabinet hole 72.

[0037] See Figure 4 , Figure 6 The L-shaped upward-folding baffle has a third cabinet-joining hole 73 at its edge, top, and the joint of the outer box body. The third cabinet-joining hole 73 at the top and the joint of the outer box body has a pre-drilled threaded hole (which can be riveted). The L-shaped upward-folding baffle bolt assembly 62 passes through the third cabinet-joining hole 73 located on the baffle and connects and joins the L-shaped upward-folding baffles 5 of the three independent compartments. The L-shaped upward-folding baffle bolt assembly 62 preferably uses double rows of bolts at the front and back to reduce the top gap. The top cabinet-joining strip bolt assembly passes through the third cabinet-joining hole 73 located on the top and connects and fixes the L-shaped upward-folding baffle 5 and the top cabinet-joining strip 41. The outer box cabinet-joining strip bolt assembly passes through the third cabinet-joining hole 73 located at the joint of the outer box body and connects and fixes each of the front and back cabinet-joining strips 42 to cover the cabinet-joining gaps, improve the appearance and protection level.

[0038] See Figure 6 The L-shaped upward-folding edge 5 and the top cabinet strip 41 are fixed by the connecting component 6 to form a labyrinth-type waterproof structure, providing high protection. No additional waterproof strips or waterproof sealant are required, and there is no leakage in the rain test.

[0039] In this embodiment, the cabinet-connecting holes 7 are distributed according to the principle of equal strength, with a preferred spacing of ≤300mm, and the hole diameter is adapted to high-strength bolts. For example, M16 high-strength bolts are preferably used at the first cabinet-connecting hole, and M12 high-strength bolts are preferably used at the second cabinet-connecting hole.

[0040] In this embodiment, the size of each independent compartment is within 2.5m*2m*2.5m. Since the volume of the independent compartment is smaller than that of a conventional prefabricated substation, about 1 / 3, it is convenient for the new type of split prefabricated substation to be loaded into a container, which facilitates long-distance transportation.

[0041] In this embodiment, each independent compartment is preferably constructed from a 2mm thick galvanized steel sheet, independently welded, and pre-installed with equipment, which will not be described here. If galvanized steel sheets of other thicknesses are used, they are also within the scope of protection of this utility model.

[0042] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0043] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Since these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
