The utility model discloses a distribution transformer incorporate device integrated with a distribution box, comprising a distribution box (1) and a transformer (2), and characterized in that the distribution box (1) and the transformer (2) are arranged side by side in a same box iron stand (5); a low voltage side outgoing line of the transformer (2) enters the distribution box from the lower side of the distribution box through a power cable; four corners (3) of the transformer (2) are provided with oblique corrugated sheets (4); the oblique corrugated sheets (4) are arranged at intermediate positions of the corners (3), and form angles of 45 DEG with adjacent surfaces; the high voltage side corrugated sheet length of the transformer (2) is greater than the lower voltage side corrugated sheet length of the transformer (2); lower voltage side corrugated sheets of the transformer (2) are located between the transformer (2) and the distribution box (1). The distribution transformer incorporate device can adjust corrugated sheet structures on the periphery of the transformer, and meet the requirement of integrative installation with the distribution box, and has better heat dissipation performance.
