For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0033] As in the background art, the three-dimensional wound core transformer is a special transformer whose core structure is composed of three closed loops. This structure makes the three-dimensional wound core transformer have higher magnetic flux density and lower magnetic resistance, thereby improving the efficiency and performance of the transformer. However, this special core structure also brings great challenges to winding. Traditional winding machines are usually suitable for flat or open core structures, because they can wind wires on the core through simple mechanical movement. However, for the closed loop structure of the three-dimensional wound core transformer, the traditional winding machine cannot be directly applied. This is because the structure of the closed loop limits the entry and movement of the wire, making the winding process very difficult.

[0034] To improve the above problems, the three-dimensional wound core transformer winding drum is provided, which can efficiently perform winding operation on the complex closed loop structure through the winding drum specially designed for the three-dimensional wound core. This design overcomes the challenges that the traditional winding machine cannot cope with, making the winding process more smooth and fast, greatly improving the production efficiency. The winding drum holds the transformer core column by two clamping rings, and is equipped with quick release structure and pull hook fixing pin, ensuring the stability of the equipment during winding. The design of the pressing handle further enhances the tightness between the clamping ring and the core column, ensuring the winding accuracy and the constant wire tension, thereby improving the performance and reliability of the transformer. The winding drum adopts modular design, and the clamping ring and the gear disc assembly can be quickly disassembled, facilitating the installation, debugging and maintenance of the equipment. The design of the arc-shaped pin makes the half gear disc easily separated or locked, simplifying the operation process and reducing the operation difficulty and time cost. Since the inner diameter of the supporting cylinder is larger than the outer diameter of the transformer core column, and the winding drum can be adjusted according to different specifications of the core, the device has good universality and can adapt to various sizes and models of three-dimensional wound core transformers, enhancing the flexibility of its market application.
