Technical Field
[0001] The utility model relates to the technical field of mobile substations, in particular to a mobile substation. Background Art
[0002] Mobile box-type substation is a kind of factory-prefabricated indoor and outdoor compact distribution equipment that integrates high-voltage switchgear, distribution transformer and low-voltage distribution device according to a certain wiring scheme. It organically combines the functions of transformer step-down and low-voltage distribution, and is installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulating, fully enclosed, movable steel structure box. It is particularly suitable for urban network construction and transformation, and is a new type of substation that has emerged after the civil substation.
[0003] The transformer of the mobile substation is placed in a closed shell and installed, so the heat dissipation requirement is relatively high. It is difficult to meet the heat dissipation requirements of the substation by relying solely on the heat dissipation holes on the side surface of the box. Therefore, we propose a mobile substation. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mobile substation, comprising a base plate and a transformer box, wherein the transformer box is supported and fixed on the upper surface of the base plate, and an opening is provided on the top surface of the transformer box, in which a copper plate is laterally embedded and fixed; a plurality of mutually parallel lower fins are laterally evenly connected to the bottom surface of the copper plate, and the lower fins are placed inside the transformer box, and a plurality of mutually parallel upper fins are laterally evenly connected to the upper surface of the copper plate, and a mesh plate is vertically fixed to the side of the upper fin, and a fan is installed on the surface of the mesh plate.
[0006] By adopting the above technical solution, a copper plate is embedded and fixed above the transformer box, and its bottom is connected to the lower fins placed inside the box. The heat from the working transformer inside the box can be quickly absorbed and transferred to the copper plate, and then dissipated through the upper fins on the surface of the copper plate, ensuring the heat dissipation effect of the equipment.
[0007] Optionally, four lifting rings are fixed to the four bottom corners of the base plate, and there are four lifting rings.
[0008] By adopting the above technical solution, the base plate and the transformer box can be lifted through the lifting rings at the four corners of the base plate.
[0009] Optionally, a through hole is opened on the surface of the lower fin, and a plurality of through holes are provided and evenly distributed on the surface of the lower fin.
[0010] By adopting the above technical solution, the through holes arranged on the surface of the lower fins can make the air inside the transformer box flow better and fill between the lower fins, so that the air absorbs heat and transfers it to the copper plate.
[0011] Optionally, a shield is fixed to the upper support of the transformer box, and the lower fins and the fan are placed below the shield.
[0012] By adopting the above technical solution, the shield is supported at the top, which can achieve the purpose of sun protection for the upper fins and rain protection for the fan.
[0013] Optionally, pillars are vertically supported and fixed at the four corners of the bottom of the shield, and the shield is supported above the transformer box by the pillars.

[0016] 1. The technical solution of the present application embeds and fixes a copper plate in the upper opening of the transformer box, and the lower fins are evenly placed inside the transformer box through the bottom, which can better absorb heat and transfer it to the copper plate, and then the upper fins cooperate with the blowing action of the fan to better dissipate the heat, thereby ensuring the heat dissipation requirements of the transformer inside the substation.

[0022] See also Figure 1-2 The utility model provides a technical solution: a mobile substation, including a base plate 1 and a transformer box 2, the transformer box 2 is supported and fixed on the upper surface of the base plate 1, and four lifting rings 11 are fixed at the four corners of the bottom of the base plate 1. When the transformer box 2 is transported, the lifting rope can be connected to the lifting rings 11 at the four corners of the base plate 1 to realize the lifting and transportation of the base plate 1 and the substation.
[0023] An opening 21 is provided on the top surface of the transformer box 2, and a copper plate 3 is laterally embedded and fixed in the opening 21. The upper and lower surfaces of the copper plate 3 are respectively placed on the outside and inside of the transformer box 2. A lower fin 32 is laterally connected and fixed to the bottom surface of the copper plate 3. A plurality of lower fins 32 are provided and are parallel to each other in the longitudinal direction. In order to allow hot air to flow smoothly between the lower fins 32, a through hole 321 is provided on the surface of the lower fin 32. A plurality of through holes 321 are provided and are evenly distributed on the surface of the lower fin 32. The heat generated by the transformer during operation can be absorbed by the lower fin 32 and transferred to the copper plate 3.
[0024] An upper fin 31 is laterally connected and fixed to the upper surface of the copper plate 3. There are multiple upper fins 31 and they are parallel to each other in the longitudinal direction. A mesh plate 312 is vertically fixed to the left side of the upper fin 31. A fan 311 is installed on the surface of the mesh plate 312. There are multiple fans 311, and the air outlet of the fan 311 faces the left side. When the fan 311 is working, the external air flows through the upper fins 31, which can better carry away the heat, thereby achieving the purpose of heat dissipation for the copper plate 3 and dissipating the heat inside the transformer box 2.
[0025] A shield 4 is horizontally arranged above the transformer box 2, and pillars 41 are vertically supported and fixed at the four corners of the bottom of the shield 4. The shield 4 is supported above the transformer box 2 by the pillars 41, and the lower fins 32 and the fan 311 are both placed below the shield 4. The shield 4 can protect the upper fins 31 from the sun and protect the fan 311 from rain.
[0026] When in use, the base plate 1 and the transformer box 2 above it can be lifted through the lifting ring 11, and the equipment can be transported after being lifted to the surface of the car. When the equipment is connected to the power grid and the substation is working, the fan 311 is connected to the low-voltage power supply and started to work. Since there are multiple lower fins 32 on the base plate 1 of the copper plate 3 and placed inside the transformer box 2, combined with the through holes 321 set on its surface, the hot air inside the transformer box 2 can flow through the through holes 321 and fill between the lower fins 32, so that the lower fins 32 can absorb the heat of the transformer inside the transformer box 2 when it is working and transfer it to the copper plate 3, and the heat is transferred to the surface of the upper fin 31. Under the action of the fan 311 blowing, the heat can be quickly dissipated, thereby achieving the purpose of good heat dissipation of the transformer inside the transformer box 2. During use, the shield 4 can also play a role in sun protection for the upper fin 31 and waterproofing for the fan 311.
