The box body of the European-style substation is composed of three parts: a base, an outer shell, and a top cover. The base is generally made of channel steel, angle steel, flat steel, steel plate, etc., and is welded or connected with bolts to form a fixed shape; in order to meet the needs of ventilation, heat dissipation and wire access, strip holes and moderately sized circles should be opened at the corresponding positions.形孔. Shaped hole. The box shell, top cover channel steel, angle steel, steel plate, aluminum alloy plate, color steel plate, cement board, etc. are bent, assembled or connected by screws, hinges or related special accessories.
Regardless of the material of the box-transformer shell, it must have the following five prevention functions: sun, rain, dust, rust, and small animals (such as snakes) from entering according to the standard requirements. In order to prevent the strong solar radiation in the hot summer, the shell of European-style substation is generally equipped with insulation material with low thermal conductivity as filler. Commonly used fillers are: rock wool board, polystyrene foam and so on.
In the traditional "combined substation" of unified design, the shell is usually filled with insulating fillers. This method is no longer adopted by most designers. This is because the insulating fillers can prevent strong solar radiation in hot summer At the same time, it also hinders the dissipation of a large amount of heat generated during the operation of the transformer. Therefore, in addition to the method of punching the blind holes on the shell, the designers also adopt the method of increasing the heat dissipation area and strengthening the air convection to dissipate the heat, while reducing the manufacturing cost.
The surface of the European-style box change: There are many methods for the surface of the European-style box change. In northern China, traditional methods such as painting, baking, and spraying are mostly used for treatment; in the economically developed areas of southern China, in addition to the above methods, there are also Paste colored tiles on the outer shell of the cement board structure, or paste veneers and other methods for surface treatment, especially the appearance of the box change placed in the residential area, which is more coordinated and unified with the style of the local buildings.
