Transformer oil tank structure with a step-shaped ascending flanged base

The invention relates to the technical field of transformer manufacturing, and provides a transformer oil tank structure with a step-shaped ascending flanged base, which comprises an oil tank main body in which a plurality of single-phase transformers are arranged, and further comprises an ascending flanged base which is step-shaped and is arranged on the side wall of the oil tank main body, and the interior of the ascending flanged base is communicated with the interior of the oil tank main body; and the structure also comprises a plugging cable head arranged on the step of the ascending flanged base and used for connecting a secondary side winding of the single-phase transformer. By means of the technical scheme, the problems that in the prior art, the number of cable heads pulled out and inserted by an in-phase power supply transformer is large, arrangement is compact, and installation and replacement are inconvenient are solved. 本发明涉及变压器制造技术领域，提出了一种带台阶形升高座的变压器油箱的结构，包括油箱主体，油箱主体内设置多个单相变压器，还包括：升高座，升高座为台阶形，设置
