One end is bolt-connected to the terminal by a copper row, and the other end is welded by using the copper-aluminum explosion welding process; Disadvantages: The copper-aluminum explosion welding process is complex and costly.

[0004] Now, in order to solve the above technical problems, the utility model designs a current transmission structure of a graphitization system. Summary of the Utility Model

[0020] As Figure 1 shown, a current transmission structure of a graphitization system, characterized in that: it includes a transformer 1, a rectifier cabinet 2, a copper flexible 3, a small aluminum row 4, and a bus aluminum row 5. A copper row 11 is provided at the terminal of the transformer 1, and the end of the copper row 11 is connected to the copper flexible 3. One end of the small aluminum row 4 is welded to the bus aluminum row 5, and the other end is connected to the copper flexible 3.

[0021] Between the end of the copper row 11 and the copper flexible 3, and between the copper flexible 3 and the small aluminum row 4, bolt connections are used. The detachable feature of the bolt connection makes regular inspection and maintenance simple, and problems can be quickly discovered and necessary adjustments or replacements can be made. When a certain component is damaged, the component can be directly replaced without replacing the entire assembly.

[0022] A layer of tin is plated on the end of the copper row 11 to improve the electrical connection performance and prevent oxidation corrosion. The tin layer can reduce the oxide layer formed when copper contacts other metals, thereby reducing the contact resistance and ensuring better current transmission.

[0023] The copper flexible 3 has upper and lower layers, which are a positive electrode layer and a negative electrode layer respectively.

[0024] The copper flexible 3 is a copper conductor with high flexibility. The copper flexible 3 has high flexibility, can adapt to slight deformation or vibration of the connection point, can absorb the stress between the connection points, reduce the damage caused by temperature change or mechanical vibration, and helps to extend the service life of the system. The flexibility of the copper flexible makes it more flexible during installation, facilitating wiring and position adjustment.

[0025] By physically separating the positive electrode and the negative electrode, electromagnetic interference between them can be reduced, and short-circuit accidents caused by accidental contact can also be effectively avoided, increasing the safety of the system. The double-layer design can increase the total surface area, helping to improve the heat dissipation efficiency.

[0026] As Figure 2 and Figure 3As shown, the flexible copper strip 3 includes a flexible connection part 35, a first clamping plate part 31, a second clamping plate part 32, and a third clamping plate part 33 and a fourth clamping plate part 34 that are mirror-symmetrical to the first clamping plate part 31 and the second clamping plate part 32. Bolt holes are provided in the first clamping plate part 31, the second clamping plate part 32, the third clamping plate part 33, and the fourth clamping plate part 34.

[0027] Through bolt connection, the flexible copper strip 3 can be easily connected to the copper busbar 11 at the transformer terminal and the small aluminum busbar 4, simplifying the installation process.

[0028] The clamping plate structure combined with bolt fixation makes the installation process simple and fast. With appropriate pre-tightening force, bolt connection can ensure a low contact resistance, thereby reducing energy loss and improving electrical performance. Compared with welding or other connection methods, bolt connection has a lower cost, reducing additional processing procedures and material costs.

[0029] In use, the transformer 1 receives alternating current from the power grid and converts it into a voltage level suitable for use in the graphitization system. The rectifier cabinet 2 converts the alternating current output by the transformer into direct current for use in the graphitization system. The rectified direct current transmits the current from the copper busbar 11 to the small aluminum busbar 4 through the flexible copper strip 3, and finally reaches the busbar aluminum busbar 5, and then is distributed to each component of the graphitization system.

[0030] The above has illustrated the present invention by way of example, but the present invention is not limited to the above specific embodiments. Any modification or variation based on the present invention falls within the scope of protection required by the present invention.
