[0002] For some existing box-type substations of new energy, in order to facilitate export to all over the world, the outer shape of the box-type substation is usually made similar to that of a container, so that the box-type substation can be stored at the dock and stacked and shipped by a transport ship. Usually, the sea transportation cycle is not very accurate, and procedures such as customs clearance need to be waited for. Therefore, the box-type substation usually needs to be stored at the dock and on the transport ship for at least one or two months. The rain and salt spray weather near the sea is likely to corrode the outer wall of the outer box of the box-type substation. In addition, the accumulated water and stains under the outer box will also cause continuous corrosion to the bottom of the outer box.
[0003] In order to reduce the risk of corrosion of the outer box of the box-type substation, an existing solution is to directly coat a paint film evenly on the outer wall of the outer box. However, it is found in practice that there is still a certain possibility that the bottom of the outer box is corroded; another existing solution is to make the whole outer box of stainless steel, but this method has a high cost.

Those skilled in the art can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.
[0027] For some existing box-type substations of new energy, in order to facilitate export to all over the world, the outer shape of the box-type substation is usually made in a form similar to a container, so that the box-type substation can be stored at the dock and stacked and shipped by a transport ship. Usually, the shipping cycle is not very accurate, and procedures such as waiting for customs clearance are required. Therefore, the box-type substation usually needs to be stored at the dock and on the transport ship for at least one or two months. The rain and salt spray weather near the sea are likely to cause corrosion to the outer wall of the outer box body of the box-type substation. In addition, the accumulated water and stains under the outer box body will also cause continuous corrosion to the bottom of the outer box body.
[0028] In order to reduce the risk of corrosion of the outer box body of the box-type substation, an existing solution is to directly coat a paint film evenly on the outer wall of the outer box body. However, it is found in practice that there is still a certain possibility that the bottom of the outer box body will be corroded; another existing solution is to make the whole outer box body of stainless steel, but this method has a high cost.
[0029] Refer to Figures 1 to 3, is a box-type substation suitable for sea transportation according to an embodiment of the present invention, including an outer box body 100 and a power conversion device. The outer box body 100 is provided with an accommodation chamber; the power conversion device is arranged in the accommodation chamber of the outer box body 100; wherein a first isolation film 110 is arranged on the top and the outer walls around the outer box body 100, and a second isolation film 120 is arranged on the outer wall of the bottom of the outer box body 100, and the thickness of the second isolation film 120 is greater than that of the first isolation film 110.
[0030] The first isolation film 110 on the top and the outer walls around the outer box body 100 can isolate salt spray and rainwater. A second isolation film 120 is arranged on the outer wall of the bottom of the outer box body 100, so that the outer wall of the bottom of the outer box body 100 can have an isolation effect on salt spray and rainwater. In addition, by setting the second isolation film 120 to be thicker than the first isolation film 110, its isolation function can be strengthened, and it can better isolate accumulated water and stains under the bottom of the outer box body 100, etc., so that the outer wall of the bottom of the outer box body 100 is not easily corroded, thereby reducing the risk of corrosion of the outer box body 100 during the sea transportation process, and the cost is relatively low.
[0031] In the embodiment, both the first isolation film 110 and the second isolation film 120 are paraffin films. Using paraffin to make the first isolation film 110 and the second isolation film 120, paraffin can better isolate the corrosion of salt spray and rainwater, etc. during sea transportation, and also has a certain protective effect on sunlight irradiation. At the same time, the material cost is relatively low. And by using paraffin films, a temporary isolation and protection can be formed only during sea transportation, which is convenient to remove the paraffin films by heating and wiping, etc. after arriving at the destination, so as to improve the visual effect of the box-type substation and is suitable for destinations with relatively low anti-corrosion requirements, and the cost of temporary protection is relatively low.
[0032] It can be understood that after the box-type substation arrives at the destination, the paraffin film can also not be removed by heating, so as to extend the protection effect on the outer box body 100 of the box-type substation.
[0033] It can be understood that the first isolation film 110 and the second isolation film 120 can also be films made of other materials, and those skilled in the art can specifically configure them according to actual needs.
[0034] In an embodiment, the first isolation film 110 includes two stacked first constituent layers 111. The first constituent layer 111 is a paraffin layer, and the first isolation film 110 is formed by stacking two paraffin layers. During production, liquid paraffin can be evenly sprayed on the top and the outer walls around the outer box 100 first, and the liquid paraffin cools and solidifies to form a first constituent layer 111. Subsequently, the above operation is repeated to form other first constituent layers 111. In the above manner, multiple paraffin layers are sequentially sprayed and solidified to form the first isolation film 110, making the first isolation film 110 relatively uniform on the top and the outer walls around the outer box 100, and avoiding the risk that the liquid paraffin cannot flow down the outer wall of the outer box 100 during the process of forming a relatively thick paraffin film by one-time spraying, thus improving the process stability of the first isolation film 110.
[0035] It can be understood that the first isolation film 110 can also include three or more stacked first constituent layers 111, and those skilled in the art can specifically configure according to actual needs.
[0036] In an embodiment, the first isolation film 110 includes two stacked first constituent layers 111, and the two first constituent layers 111 have the same thickness. The above structure makes the forming difficulty of each first constituent layer 111 similar, facilitating the unification of the production processes of the first constituent layers 111 and reducing the production complexity of the first isolation film 110. It can be imagined that the thicknesses of the two first constituent layers 111 can also be different, and those skilled in the art can specifically configure according to actual needs.
[0037] In an embodiment, the second isolation film 120 includes two stacked second constituent layers 121. The second constituent layer 121 is a paraffin layer, and the second isolation film 120 is formed by stacking two paraffin layers. During production, liquid paraffin can be evenly sprayed on the bottom outer wall of the outer box 100 first, and the liquid paraffin cools and solidifies to form a second constituent layer 121. Subsequently, the above operation is repeated to form other second constituent layers 121. In the above manner, multiple paraffin layers are sequentially sprayed and solidified to form the second isolation film 120, making the second isolation film 120 relatively uniform on the bottom outer wall of the outer box 100, and avoiding the risk that the liquid paraffin cannot flow down the outer wall of the outer box 100 during the process of forming a relatively thick paraffin film by one-time spraying, thus improving the process stability of the second isolation film 120.
[0038] It can be understood that the second isolation film 120 can also include three or more stacked second constituent layers 121, and those skilled in the art can specifically configure according to actual needs.
[0039] In an embodiment, the second isolation film 120 includes two stacked second constituent layers 121, and the two second constituent layers 121 have the same thickness. The above structure makes the forming difficulty of each second constituent layer 121 similar, facilitating the unification of the production processes of the second constituent layers 121 and reducing the production complexity of the second isolation film 120. It can be imagined that the thicknesses of the two second constituent layers 121 can also be different, and those skilled in the art can configure them specifically according to actual needs.
[0040] In an embodiment, a paint film is further provided on the outer wall of the outer box body 100, and the first isolation film 110 and the second isolation film 120 are located outside the paint film. The above structure provides better protection for the outer box body 100. The paraffin film can also protect the paint film, making the paint film not easily damaged or faded.
[0041] In an embodiment, the thickness A of the first isolation film 110 satisfies: 10 μm ≤ A ≤ 15 μm. Through tests, it can meet the anti-corrosion requirements of the top and the outer walls around the outer box body 100, and save the material of the first isolation film 110 as much as possible to reduce the production cost. It can be understood that the thickness of the first isolation film 110 can be 10 μm, 13 μm, 15 μm, etc., or any value between them, and those skilled in the art can configure it specifically according to actual needs.
[0042] In an embodiment, the thickness B of the second isolation film 120 satisfies: 25 μm ≤ B ≤ 30 μm. Through tests, it can meet the anti-corrosion requirements of the top and the outer walls around the outer box body 100, and save the material of the second isolation film 120 as much as possible to reduce the production cost. It can be understood that the thickness of the second isolation film 120 can be 25 μm, 27 μm, 30 μm, etc., or any value between them, and those skilled in the art can configure it specifically according to actual needs.
[0043] In an embodiment, both the first isolation film 110 and the second isolation film 120 are hot-melt films. When it is necessary to remove the first isolation film 110 and the second isolation film 120, the outer wall of the outer box body 100 can be heated to relatively conveniently remove the first isolation film 110 and the second isolation film 120 to meet the usage requirements for different destinations.
