Description

Technical Field

[0001] This utility model relates to the field of mobile substation technology, specifically a mobile substation housing. Background Technology

[0002] A mobile prefabricated substation is a combination of high-voltage switchgear, distribution transformer, and low-voltage power distribution equipment. It organically integrates 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. It is particularly suitable for urban power grid construction and renovation, and is a brand-new type of substation that has emerged after civil engineering substations.

[0003] Existing domestically produced prefabricated substations generally adopt an independent structure for each unit, with separate transformer room, high-voltage switch room, and low-voltage switch room, which are connected by wires to form a complete power supply system. In the power system, mobile substations have the advantages of short construction period, small footprint, convenient maintenance, and high reliability.

[0004] However, traditional mobile substations have limited space for cable channels under prefabricated equipment cabinets, making it difficult to drill holes, inconvenient for wiring, prone to cable wear, and have poor insulation and moisture protection, resulting in certain defects in use. Therefore, we propose a mobile substation enclosure to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a mobile substation housing to solve the problems mentioned in the background art, such as limited space for cable channels under the prefabricated equipment cabinets of existing mobile substations, difficulty in opening holes, inconvenience in wiring, easy wear of cables, and poor heat insulation and moisture protection inside.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a movable substation shell, comprising a support frame and a top plate fixedly installed on the top of the support frame, wherein a wall structure is fixedly installed on the inner side of the support frame, the wall structure comprising an outer galvanized corrugated plate and an inner decorative plate fixedly installed inside the support frame, and the inner sides of the outer galvanized corrugated plate and the inner decorative plate are filled with a foam layer.

[0007] The inner side of the support frame is provided with a base structure, and the base structure includes a first fixed frame fixedly installed at the bottom position of the inner side of the support frame and a second fixed frame fixedly installed at the top position of the inner side of the support frame. A truss is welded and fixed inside the first fixed frame, and a wiring frame is welded and fixed inside the truss. A limit member is provided on the outer side of the wiring frame.

[0008] As a preferred embodiment of this utility model, the inner side of the base structure is provided with a lateral wiring structure, and the lateral wiring structure includes a connecting ring connecting the first fixed frame and the second fixed frame.

[0009] As a preferred technical solution of this utility model, both the first fixed frame and the second fixed frame are welded and fixed by channel steel structure to form a right-angled quadrilateral structure.

[0010] As a preferred embodiment of this utility model, the trusses are evenly distributed on the outside of the wiring frame and provide support for the wiring frame.

[0011] As a preferred technical solution of this utility model, the wiring frame is welded from angle steel, and the wiring frame is symmetrically distributed on the inner side of the first fixed frame.

[0012] As a preferred technical solution of this utility model, the limiting member includes a connecting block sleeved on the outside of the wiring frame, and a connecting strip is integrally fixed on one outer end face of the connecting block.

[0013] As a preferred embodiment of this utility model, the end face of the connecting block that contacts the top of the wiring rack is closed.

[0014] As a preferred embodiment of this utility model, the lateral wiring structure further includes a fixing ring welded to the top of the first fixing frame, and a fixing ring welded to the bottom of the second fixing frame. The fixing ring is connected to both ends of the connecting ring and provides support for the connecting ring.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the mobile substation shell reduces construction costs and improves construction efficiency while ensuring strength; at the same time, it effectively reduces wear on cables and improves the overall thermal insulation, moisture resistance and sound insulation effect to a certain extent.

[0016] 1. The cabling frame is made of angle steel and welded together, eliminating the need for opening holes. This saves on the tedious opening process, reduces construction costs, and improves construction efficiency. At the same time, the cable is limited by the limiting component, so that the cable passes between the connecting block and the connecting strip during cabling, reducing the amount of cabling work and avoiding contact between the cabling frame and the cable, which would cause cable wear.

[0017] Furthermore, by replacing the cable routing on one side of the equipment cabinet with a channel steel structure, the cables pass through the connecting rings for routing, which is flexible and less prone to cable wear. At the same time, by increasing or decreasing the number of units connected by the connecting rings, the connection length of the connecting rings can be flexibly adjusted to adapt to equipment cabinets of different heights.

[0018] 2. By filling the inner side of the outer galvanized corrugated sheet and the inner decorative sheet with a foam layer, the durability and moisture resistance of the portable substation shell are improved, while the overall heat insulation and sound insulation of the shell are enhanced.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-8This utility model provides a technical solution: a movable substation shell, including a support frame 1 and a top plate 2 fixedly installed on the top of the support frame 1, combined with... Figure 1 and Figure 6 As shown, a wall structure 300 is fixedly installed on the inner side of the support frame 1. The wall structure 300 includes an outer galvanized corrugated plate 301 and an inner decorative plate 302 fixedly installed inside the support frame 1. A foam layer 303 is filled on the inner side of the outer galvanized corrugated plate 301 and the inner decorative plate 302. The foam layer 303 is filled between the outer galvanized corrugated plate 301 and the inner decorative plate 302 to improve the durability, moisture resistance and sound insulation of the mobile substation shell.

[0030] Specific examples Figure 2 As shown, a base structure 400 is provided on the inner side of the support frame 1. The base structure 400 includes a first fixed frame 410 fixedly installed at the bottom position of the inner side of the support frame 1 and a second fixed frame 440 fixedly installed at the top position of the inner side of the support frame 1. Both the first fixed frame 410 and the second fixed frame 440 are welded and fixedly formed by channel steel structure to form a right-angled quadrilateral structure. At the same time, a truss 420 is welded and fixedly fixed inside the first fixed frame 410, and a wiring frame 430 is welded and fixedly fixed inside the truss 420. Specifically, as shown... Figure 2 As shown, trusses 420 are evenly distributed on the outside of the wiring rack 430 and provide support for the wiring rack 430.

[0031] Combination Figure 7 and Figure 8 As shown, the wiring rack 430 in the prior art is usually welded from a channel steel structure. At the same time, by slotting or opening the inside of the channel steel structure, the cable passes through the inside of the slot structure to achieve the function of limiting the cable. The bending part of the channel steel is in contact with the cable for a long time, which can easily cause wear to the cable.

[0032] Specific examples Figure 2 and Figure 3 As shown, in the shell of the mobile substation, the wiring rack 430 is welded from angle steel and no openings are required. The wiring rack 430 is symmetrically distributed on the inner side of the first fixed frame 410, which eliminates the cumbersome opening steps, reduces construction costs, and improves construction efficiency.

[0033] Furthermore, a limiting member 500 is provided on the outside of the cabling rack 430, and the limiting member 500 includes a connecting block 510 sleeved on the outside of the cabling rack 430, and a connecting strap 520 is integrally fixed on one outer end face of the connecting block 510. At the same time, the end face of the connecting block 510 that contacts the top of the cabling rack 430 is closed, specifically as follows. Figure 3 and Figure 5As shown, the cable is limited by the limiting member 500. At the same time, since the connecting block 510 and the connecting strip 520 are both integrally molded from insulating silicone material, the cable passes between the connecting block 510 and the connecting strip 520 during wiring, which reduces the amount of wiring work and avoids the cable frame 430 from contacting the cable and causing cable wear. In addition, since the connecting block 510 has a certain elastic deformation, it can be disassembled from the outside of the cable frame 430 and reused.

[0034] Specific examples Figure 2 and Figure 4 As shown, a lateral wiring structure 600 is provided on the inner side of the base structure 400. The lateral wiring structure 600 includes a connecting ring 620 connecting the first fixed frame 410 and the second fixed frame 440. The lateral wiring structure 600 also includes a fixing ring 610 welded and fixed to the top of the first fixed frame 410. A fixing ring 610 is also welded and fixed to the bottom of the second fixed frame 440. The fixing ring 610 is connected to both ends of the connecting ring 620 and provides support for the connecting ring 620. The connecting ring 620 is made of insulating silicone material.

[0035] Specific examples Figure 7 As shown, since equipment cabinets need to be installed inside the substation shell, in the prior art, when wiring cables on one side of the equipment cabinet, the cables are passed through the slots or holes in the channel steel structure to limit the cables. However, the edges of the slots in the channel steel are in contact with the cables for a long time, which can easily cause wear to the cables. By replacing the channel steel with a lateral wiring structure 600, the cables pass through the connecting ring 620 for wiring. This makes the operation more flexible and less likely to wear the cables. At the same time, the fixing ring 610 and the connecting ring 620 are detachable. Furthermore, by increasing or decreasing the number of units connected by the connecting ring 620, the connection length of the connecting ring 620 can be flexibly adjusted to adapt to equipment cabinets of different heights.

[0036] The working principle of this utility model is as follows: When using this portable substation housing, the channel steel at the bottom of the equipment cabinet inside the housing is replaced with angle steel, reducing wiring workload and cable wear, and improving efficiency. Specifically, as shown below... Figure 2 and Figure 3 As shown, the cabling frame 430 is constructed from angle steel and eliminates the need for openings, thus avoiding cumbersome opening procedures, reducing construction costs, and improving construction efficiency. Simultaneously, the cable is limited by the limiting component 500, combined with... Figure 4 and Figure 5 As shown, during cabling, the cable is passed between the connector block 510 and the connector strip 520 to reduce cabling workload and avoid cable wear caused by contact between the cabling frame 430 and the cable.

[0037] Specific examples Figure 2 and Figure 4As shown, by replacing the cable routing on one side of the equipment cabinet with channel steel and using a lateral cabling structure 600, the cables pass through the connecting ring 620 for cabling, which is flexible and less likely to wear the cables. At the same time, the fixing ring 610 and the connecting ring 620 are detachable.

[0038] Specific examples Figure 1 and Figure 6 As shown, the foam layer 303 is filled between the outer galvanized corrugated plate 301 and the inner decorative plate 302 to improve the durability, moisture resistance and sound insulation of the portable substation shell.

[0039] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
