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.
