[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-4A transformer copper busbar comprises a transformer copper busbar body 1, an extension protrusion 11 is provided at the bottom of one side of the transformer copper busbar body 1, the extension protrusion 11 comprises a horizontal fixed block portion and a vertical protrusion portion, a plurality of auxiliary extension blocks 15 are equidistantly installed on the top of the vertical protrusion portion, and a limit card slot is provided at the extension protrusion 11 on the other side of the transformer copper busbar body 1, a plurality of limit plugs 14 are equidistantly installed in the limit card slot at the horizontal fixed block portion;

[0022] In addition, a plurality of first extension protrusions 13 are installed at equal distances above the side of the transformer copper busbar body 1 close to the limiting plug 14 , and a plurality of second extension protrusions 16 are installed at equal distances on the side of the extension protrusion 11 away from the horizontal fixing block.

[0023] At the same time, one side of the horizontal fixing block is connected to the transformer copper busbar body 1, and the other side of the horizontal fixing block is connected to the vertical protrusion part, and a first through-hole is opened through the top of the horizontal fixing block at the limiting plug block 14.

[0024] Furthermore, the auxiliary extension block 15 is in a convex shape, and a second through hole is formed through the auxiliary extension block 15 in the transformer copper busbar body 1 .

[0025] Furthermore, the first extending protrusion 13 is in the shape of a triangular prism, and a first limiting groove 17 is formed at the top of the transformer copper busbar body 1 at the first extending protrusion 13 .

[0026] Furthermore, a first limiting groove 17 is formed at the bottom of the vertical protrusion portion of the extending protrusion 11 at the first extending protrusion 13 .

[0027] In addition, an arc-shaped groove 12 is provided in the middle of the top of the transformer copper bar body 1. The arc-shaped groove 12 increases the surface area of ​​the transformer copper bar body 1 and the contact area between the transformer copper bar body 1 and the cavity, thereby enhancing the air circulation. When the transformer copper bar body 1 is in use, more heat is dissipated from the surface of the transformer copper bar body 1, thereby ensuring the heat dissipation efficiency of the transformer copper bar body 1 and reducing the weight of the transformer copper bar body 1.

[0028] In this embodiment, an extension protrusion 11 is provided on one side of the transformer copper busbar body 1, and a plurality of first extension protrusions 13, limiting plugs 14, second extension protrusions 16 and auxiliary extension blocks 15 are provided on the transformer copper busbar body 1 and the extension protrusion 11, so that when the transformer copper busbar is connected to the adjacent transformer copper busbar, the connection is more secure.

[0029] When two adjacent transformer copper bars A and B need to be connected, the two adjacent transformer copper bars are plugged in, and the first extension protrusion 13 of the plugged transformer copper bar A is inserted into the first limiting groove 17 of the transformer copper bar B, and the limiting plug 14 of the transformer copper bar A is inserted into the first through plug of the transformer copper bar B.

[0030] The second extension protrusion 16 of the transformer copper busbar B is inserted into the second limiting groove 18 of the transformer copper busbar A, and the auxiliary extension block 15 of the transformer copper busbar A is inserted into the second through-insert block of the transformer copper busbar B. Then, welding can be performed at the insertion point, and the first extension protrusion 13, the limiting insert block 14, the second extension protrusion 16 and the auxiliary extension block 15 increase the surface area of ​​the welded joint.

[0031] Among them, by providing the arc-shaped groove 12, the surface area of ​​the transformer copper busbar body 1 is increased, and the contact area between the transformer copper busbar body 1 and the cavity is increased, thereby enhancing the air circulation. When the transformer copper busbar body 1 is in use, more heat is dissipated from the surface of the transformer copper busbar body 1, ensuring the heat dissipation efficiency of the transformer copper busbar body 1 while reducing the weight of the transformer copper busbar body 1.

[0032] In the present invention, an extension protrusion 11 is provided on one side of the transformer copper busbar body 1, and a plurality of first extension protrusions 13, limiting plugs 14, second extension protrusions 16 and auxiliary extension blocks 15 are provided on the transformer copper busbar body 1 and the extension protrusion 11, so that welding can be performed at the connection point after two adjacent transformer copper buses are plugged in, and the first extension protrusion 13, the limiting plug 14, the second extension protrusion 16 and the auxiliary extension block 15 increase the surface area of ​​the welding joint, thereby ensuring the firmness of the connection between the two adjacent transformer copper buses.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
