[0026] The main support 1 is provided with a connecting column 15 for connecting the first connecting table 11 and the second connecting table 12. The connecting column 15 is centrally arranged on the main support 1, and is provided with a through hole 151. The first cover plate 2 is provided with a first through hole 21, and the second cover plate 3 is provided with a second through hole 31. The first through hole 21 and the second through hole 31 are respectively opposite to both ends of the through hole 151. First mounting clamps 211 are arranged on both sides of the first through hole 21, and second mounting clamps 311 are arranged on both sides of the second through hole 31. In this embodiment, the connecting column 15 is centrally arranged on the main support 1, which ensures uniform stress on the magnetic pole piece in the horizontal direction and avoids deformation or loosening caused by uneven stress. The through hole 151 on the connecting column 15, the first through hole 21 of the first cover plate 2, and the second through hole 31 of the second cover plate 3 are aligned to form a through fixing channel, which facilitates subsequent fastening operations. In addition, the first mounting clamps 211 and the second mounting clamps 311 arranged on both sides of the first through hole 21 and the second through hole 31 respectively are key innovative points in this fixing structure. These clamps not only enhance the connection strength between the cover plate and the connecting column 15, but also realize tight fitting and fixing of the edge of the magnetic pole piece through their unique elastic design. This design not only simplifies the installation process, reduces the number of fasteners such as bolts, and thus reduces the assembly cost, but also effectively disperses the stress on the magnetic pole piece through the uniform distribution of the clamps, reducing the risk of fatigue damage caused by long-term operation. The fixing structure also has excellent adjustability and flexibility. Since the design of the connecting column 15 and the through hole allows for fine tuning within a certain range, it can be adaptively adjusted according to magnetic pole pieces of different models or sizes to ensure optimal fixing effect and electrical performance. This flexibility is crucial for improving the universality and efficiency of the production line, especially when dealing with diversified product lines, which can significantly reduce the time cost of changing tooling. In addition, from the perspective of safety, this fixing structure effectively prevents the magnetic pole piece from falling off or moving in a high-voltage and high-current environment through stable connection and uniform stress distribution, thereby ensuring the safety and reliability of the transformer operation. This is of great significance for maintaining the stable operation of the power system and avoiding power outages caused by equipment failure.

The first cover plate 2 is provided with a first matching buckle 22, which is used to match the first positioning buckle 113. Specifically, the second connecting platform 12 is provided with a second assembly positioning strip 122 and a second positioning buckle 123 on the side facing the second cover plate 3, and the second assembly positioning strip 122 is used for assembly positioning of the second pole piece 5. The second cover plate 3 is provided with a second matching buckle 32, which is used to match the second positioning buckle 123. In this embodiment, the first assembly positioning strip 112 provided on the side of the first connecting platform 11 facing the first cover plate 2 provides a precise positioning reference for the assembly of the first pole piece 4. This design not only simplifies the assembly process and reduces the errors caused by manual intervention, but also ensures the positional accuracy of the pole piece during assembly, thereby improving the stability and reliability of the overall structure. At the same time, the cooperation of the first positioning buckle 113 and the first matching buckle 22 realizes the effective fixation of the first pole piece 4, avoiding the loosening or displacement of the pole piece due to vibration or external force, and further ensuring the normal operation of the transformer. Similarly, the cooperation between the second connecting platform 12 and the second cover plate 3 also follows the same design principle. The second assembly positioning strip 122 provides clear positioning guidance for the assembly of the second pole piece 5, ensuring the accuracy and consistency of the assembly. The close cooperation of the second positioning buckle 123 and the second matching buckle 32 further enhances the fixation effect of the pole piece and improves the stability of the overall structure.

This design avoids the loosening or displacement problems that may occur in traditional fixing methods, ensuring the position accuracy and stability of the magnetic pole piece during long-term operation, thereby improving the overall performance and reliability of the transformer. Secondly, the assembly mechanism between the second connecting platform 12 and the second cover plate 3 also adopts the buckling method of buckles and clamping grooves, but the direction is opposite. This design not only realizes the symmetry of the structure, but also enhances the complementarity and redundancy of the structure. Even if the assembly buckle or clamping groove on one side is slightly worn or deformed, the assembly mechanism on the other side can still maintain good buckling effect, thereby prolonging the service life of the entire fixing structure. In addition, this assembly method also brings the advantages of convenient installation and maintenance. The operator does not need to use complex tools or equipment to complete the fixing and disassembly work of the magnetic pole piece, greatly improving the work efficiency. At the same time, the design of assembly buckles and clamping grooves makes it easy to disassemble the magnetic pole piece when replacing or repairing, reducing the maintenance cost and time cost.

In the embodiment, the opposite arrangement of the first wiring clamping groove 131 and the second wiring clamping groove 141 not only ensures the accuracy and stability of electrical connection, but also effectively simplifies the wiring process and improves the installation efficiency. Further, the opposite arrangement of the first threading groove 24 on the first cover plate 2 and the first wiring clamping groove 131, and the corresponding arrangement of the second threading groove 34 on the second cover plate 3 and the second wiring clamping groove 141, constitute an efficient and orderly cable management system. This design allows the cable to pass through the fixed structure in a more intuitive and standardized manner, avoiding the disorder of the cable and reducing the safety hazards caused by the interlacing of the cable, and also facilitating subsequent maintenance inspection and troubleshooting. In practical application, this design significantly improves the overall reliability and safety of the transformer pole piece fixing structure. On the one hand, the precise cooperation of the wiring clamping groove and the threading groove effectively prevents the cable from loosening or falling off, ensuring the durability and stability of the electrical connection; on the other hand, the neat cable layout reduces the possibility of electromagnetic interference, improving the running efficiency and performance stability of the transformer.
