Modularized galvanized sheet box transformer substation assembly structure

The utility model discloses a modularized galvanized sheet box transformer substation assembly structure, and relates to the technical field of galvanized sheets. According to the modularized galvanized plate box transformer substation assembling structure, through arrangement of the connection assembly and the positioning assembly, a corresponding positioning shaft sleeve can be inserted into a limiting groove, so that the positioning shaft sleeve can be inserted into a threaded hole formed in the end part of a limiting frame through an external thread formed in the outer side; then the pulling plates are pulled outwards to drive the corresponding connecting columns to move upwards to be separated from the clamping grooves, then the positioning shaft sleeves are rotated to fix the limiting frames and the top plate, the pulling plates are inserted into the clamping grooves again, and positioning among the pulling plates, the positioning shaft sleeves, the top plate and the limiting frames is kept; after the l
