Constant-temperature low-voltage prefabricated substation

The utility model discloses a constant-temperature low-voltage preassembled transformer station, and particularly relates to the technical field of transformer stations, the constant-temperature low-voltage preassembled transformer station comprises an electrical box, a sealing door is hinged to the front side of the electrical box, and a group of air inlet holes are uniformly arranged on the sealing door in a penetrating manner. The heat dissipation assembly and the water drainage assembly are designed, the motor can drive the first rotating shaft to rotate around the axis of the motor through the first synchronous belt wheel, the first rotating shaft rotates and drives the second rotating shaft to synchronously rotate around the axis of the motor through the second synchronous belt wheel, and the first rotating shaft and the second rotating shaft rotate and drive the fan blades to synchronously rotate at the same time. The fan blades are arranged in the electrical box, air blown out by the fan blades conduc
