摘要（英）：

The utility model discloses a casing of a preassembled boosting box-type transformer station used for wind power and photovoltaic generation. The casing comprises a casing body (1), a ventilation heat dissipation opening of which is provided with a double-shutter combination (11). The double-shutter combination (11) comprises an outer shutter (2) and an inner shutter (3). A top part of the outer shutter (2) and a top part of the inner shutter (3) are connected together. The outer shutter (2) is disposed on an outer side of the casing body (1), and the inner shutter (3) is embedded in a casing plate or a door plate of the casing body (1). The inner shutter (3) and the outer shutter (2) are opposite to each other, and a gap (4) is arranged between the inner shutter (3) and the outer shutter (2). A blade I (5) of the outer shutter (2) is in the shaped of an inverted Y, and a blade II (7) of the inner shutter (3) is in the shape of an inverted Y. By using the casing, the sand and the dust can be shielded, and the ventilation and the heat dissipation can be guaranteed.
