A high-pressure side at the upper end of the transformer tank is connected with an ascending flanged base, and the ascending flanged base comprises a first barrel and a second barrel which are vertically connected. One end in the first barrel, which is close to the second barrel, is provided with a mutual inductor, and the two ends of the mutual inductor are respectively connected with insulating branch pipes. A cable plug is arranged in the second barrel, a cable in the cable plug is connected with the transformer tank through the insulating branch pipes, and the cable plug comprises a jack arranged in the second barrel and a plug arranged outside the second barrel. In the high-pressure side cable incoming device for the transformer, the high-pressure side cable incoming mode is adopted, therefore, the size of the integral transformer appearance is reduced, and the building area and space are saved. Due to the adoption of the pull type cable plug, the safety distance between a human body and a charged body is reduced, power supply in a deep load center is suitable, the power transmission distance is shortened, and the line loss is reduced.
