A high-voltage outlet structure of an oil-immersed distribution transformer, including a tank cover, an oil tank, a high-voltage cable, a high-voltage bushing seat, and an elbow-shaped cable head plugged into the high-voltage bushing seat, wherein: the high-voltage bushing seat is sealed and installed On the tank cover or on the side wall of the fuel tank, the tail conductive part of the elbow cable head is connected to the high-voltage cable, and the connection method can be cold pressure welding. The present invention uses the high-voltage bushing seat and the elbow-shaped cable head to replace the porcelain bushing in the prior art, so that there is no exposed charged body on the high-voltage side of the transformer, and it can effectively prevent the damage caused by small animals climbing to the high-voltage terminal. The accident, improve the anti-fouling function of the transformer. At the same time, the elbow-shaped cable head and high-voltage bushing seat can be made of polymer insulating material, which has certain toughness, and is not easy to be damaged during the transportation and operation of the transformer, ensuring safety performance. In addition, after adopting the present invention, the distance between the three-phase high-voltage bushing seats can also be reduced.
