Technical Field

[0001] The utility model relates to the technical field of transformer copper bar fixing, in particular to a transformer copper bar fixing plate. Background Art

[0002] A transformer is an electrical device that uses the principle of electromagnetic induction to change AC voltage. It is mainly composed of a primary coil, a secondary coil and an iron core. The copper busbar is part of the transformer's structure and is a low-resistance conductor used for high current transmission. It is usually installed on the low-voltage side of the transformer and communicates with other electrical equipment such as receiving cabinets, capacitor cabinets or distribution cabinets for power supply.

[0003] However, it still has the following disadvantages in actual use:

[0004] During installation and use, the existing transformer copper busbars are generally fixed with laminated wood. When a short circuit occurs in the transformer, the laminated wood will break, making its function of clamping the copper busbar ineffective, thus causing the transformer to burn out, increasing costs and safety risks.

[0031] See also Figure 1-4 As shown, this embodiment is a transformer copper bar fixing plate, comprising:

[0032] A copper bar fixing part, the copper bar fixing part comprises a front laminate 11, a rear laminate 12, and a resin adhesive 13;

[0033] The front side of the resin adhesive 13 is glued to the inner side of the front laminate 11, and the inner side of the rear laminate 12 is glued to the back side of the resin adhesive 13. The front laminate 11 and the rear laminate 12 are both made of hot-pressed polyester resin plastic.

[0034] The resin adhesive 13 is used to bond and fix the front laminate 11 and the rear laminate 12 to form a fixing piece for fixing the copper busbar, and the copper busbar is structurally installed and fixed. The hot-pressed polyester resin plastic itself has good mechanical properties, high strength, toughness and wear resistance. These properties make it very effective when used to fix the low-voltage copper busbar of the transformer, reducing safety risks and costs.

[0035] Working principle: After the resin adhesive 13 is bonded to the inner side of the front laminate 11, the back side of the resin adhesive 13 is bonded and fixed to the rear laminate 12 to form a fixing part for the copper busbar, and the copper busbar can be fixed and installed in conjunction with the following connection part;

[0036] This solution uses a front laminate 11 and a rear laminate 12 made of hot-pressed polyester resin plastic, which helps to improve its own mechanical properties, increase strength, toughness and wear resistance, and reduce safety risks and use costs in subsequent use.

[0037] See also Figure 1-4 As shown, this embodiment is based on the above embodiment and further includes a connecting portion, which includes a connecting port 21, a connecting pipe 22, and a connecting ring 23;

[0038] The connection ports 21 are provided in a plurality and are opened in the middle of the front side of the front laminate 11 and penetrate the rear laminate 12. The connection pipe 22 is arranged in the connection port 21, and the connection ring 23 is symmetrically threaded on the front and rear ends of the connection pipe 22.

[0039] The connection port 21 is used to install the connection pipe 22. The connection ring 23 is used to fix the connection pipe 22 in the connection port 21. The connection pipe 22 is locked with the external bolts to fix the copper bar with the copper bar fixing part.

[0040] The inner side wall and the front and rear ends of the outer surface of the connecting pipe 22 are equidistantly provided with threads;

[0041] The threads meet the requirements of thread installation;

[0042] The inner side of the connecting ring 23 is in conflict with the front laminate 11 and the rear laminate 12 respectively;

[0043] The formation of the resistance force fixes the connecting pipe 22 in the connecting port 21;

[0044] Working principle: After placing multiple connecting tubes 22 into the connecting port 21 in sequence, the connecting rings 23 are placed in the front and rear ends of the connecting tubes 22 in sequence, and a tightening force is applied. The connecting tubes 22 are structurally installed and fixed through the resistance force formed between the inner side of the connecting ring 23 and the front laminate 11 and the rear laminate 12;

[0045] Next, the external bolts are placed therein and tightened, and the copper bar can be structurally installed through the copper bar fixing part;

[0046] According to this solution, after a bolt is stripped or broken, the connecting pipe 22 can be directly disassembled and replaced with a new connecting pipe 22 to meet the use requirements.

[0047] See also Figure 1-4As shown, this embodiment is based on the above embodiment 1 and further includes a disassembly part, which includes a movable block 31, a torsion spring 32, an opening 33, and a disassembly column 34;

[0048] The movable blocks 31 are symmetrically arranged on opposite sides of the outer surface of the connecting ring 23, and the torsion springs 32 are symmetrically fixed to the upper and lower ends of the inner side of the movable blocks 31. The opening 33 is opened through the middle of the movable block 31, and the end of the disassembly column 34 extends out of the opening 33.

[0049] The torsion spring 32 is used to install the structure of the movable block 31, and through its own elastic force, it can automatically restore the original position after the movable block 31 is rotated. The movable block 31 is used to open the opening 33, and in conjunction with the disassembly column 34, the force required for disassembly and assembly of the connecting ring 23 can be easily applied;

[0050] A fixing column 35 is fixed at the middle of the outer end of the torsion spring 32, and the outer end of the fixing column 35 is fixed inside the upper and lower ends of the outer surface of the connecting ring 23 on opposite sides;

[0051] The fixing column 35 performs structural installation on the torsion spring 32;

[0052] Working principle: When the connecting ring 23 is screwed, an external pulling force can be applied to the movable block 31 in turn, and the movable block 31 is pulled to an angle perpendicular to the front laminate 11 under the elastic force of the torsion spring 32;

[0053] Next, the disassembly post 34 is inserted through the opening 33, and a rotational tightening force is applied to the disassembly post 34 to act on the connecting ring 23, and a reverse force is applied during disassembly;

[0054] After use, the disassembly column 34 is removed, and the torsion spring 32 recovers its deformation so that the movable block 31 returns to its original position.

[0055] This solution can conveniently apply a rotational force to the connecting ring 23 during disassembly and assembly to perform threaded disassembly and assembly, thus saving time and effort.
