Description

Technical Field

[0001] This utility model belongs to the field of busbar technology, and specifically relates to a busbar packaging product, and more particularly to a packaging product for aluminum alloy busbars. Background Technology

[0002] Busbars are one of the key equipment (materials) in power transmission and transformation systems. They are mainly used in my country's power construction projects as conductors connecting power grid transmission lines and substation transformers, jumpers in transmission lines, connecting conductors in power equipment, and as current-carrying conductors in high-current DC de-icing devices. They are a new type of conductor that replaces traditional rectangular, channel, and rod-shaped busbars and flexible conductors. They play a vital role in the safe and reliable operation of power transmission and transformation systems and power equipment. They are usually made of aluminum alloy tubes.

[0003] When busbars leave the factory, they need to be packaged. In the existing technology, they are usually packaged by wrapping the busbars with pearl cotton film (usually less than 3mm thick) or wrapping them with protective film (such as PET film).

[0004] For example, patent application number CN202220653292.9 discloses a copper tube busbar winding and packaging machine, which wraps a protective film around the outside of the busbar.

[0005] The applicant discovered the following problems when actually using the aforementioned methods:

[0006] 1. Aluminum alloy is relatively soft, and the busbar may need to be transported over long distances (such as to remote areas or abroad, with transportation distances of thousands of kilometers); during transportation, the protective film is relatively thin and may be bumped and scratched.

[0007] 2. The protective film is thin and easily scratched, which affects its waterproof performance;

[0008] 3. The two ends of the busbar are usually not sealed, which allows moisture, dust and other contaminants to enter and affect the electrical performance of the busbar (such as affecting resistance, causing partial discharge, corrosion, etc.). Summary of the Invention

[0009] To address the aforementioned problems, this utility model provides a busbar packaging product. It utilizes a thicker sheet of pearl cotton for packaging and is waterproofed. Two pearl cotton end caps seal both ends of the busbar. An electrostatic film secures the pearl cotton sheet and end caps, and seals the gap between them. The technical solution is as follows:

[0010] This utility model provides a busbar packaging product, including a busbar 1 and its outer packaging; the packaging includes a pearl cotton sheet 2 and two pearl cotton end caps 3; the outer sides of the pearl cotton sheet 2 and the pearl cotton end caps 3 are coated with a waterproof membrane with a thickness greater than or equal to 7mm; the two pearl cotton end caps 3 are respectively placed on both ends of the busbar 1, and their inner sides are coaxially provided with an embedded part 4 that cooperates with the busbar 1; the pearl cotton sheet 2 covers the circumference of the busbar 1, and its two ends overlap to form a cylinder that cooperates with the busbar 1; an electrostatic film 5 is wound around the outside of the cylinder; the electrostatic film 5 at the end of the cylinder is wound in a ring with multiple layers, which simultaneously covers the end of the pearl cotton sheet 2 and the edge of the pearl cotton end cap 3, fixing the pearl cotton end cap 3 to the busbar 1; the electrostatic film 5 in the middle of the cylinder is spirally wound to fix the pearl cotton sheet 2 to the busbar 1.

[0011] In this embodiment of the utility model, the pearl cotton sheet 2 is rectangular, with a length equal to the length of the busbar 1 plus twice the thickness of the pearl cotton end cap 3, and a width greater than the outer perimeter of the busbar 1. Its wide side is aligned with the outer side of the corresponding pearl cotton end cap 3.

[0012] In this embodiment of the present invention, both the pearl cotton end cap 3 and the embedded part 4 are circular; the diameter of the pearl cotton end cap 3 is equal to the outer diameter of the busbar 1, and its inner edge abuts against the end face of the busbar 1; the diameter of the embedded part 4 is equal to the inner diameter of the busbar 1, and its height at the end of the busbar 1 is greater than or equal to 5mm.

[0013] Preferably, in this embodiment of the present invention, the embedded part 4 is a frustum-shaped structure with a larger inner part and a smaller outer part.

[0014] In this embodiment of the invention, the waterproof membrane is a PET membrane.

[0015] In this embodiment of the invention, the electrostatic film 5 is a PET film.

[0016] Preferably, in this embodiment of the invention, the outer sides of the pearl cotton sheet 2 and the pearl cotton end cap 3 are embossed to form a raised texture, and they are both made of pearl cotton without any additives.

[0017] Specifically, in the embodiments of this utility model, the raised areas of the embossed texture are square and arranged in a square array.

[0018] Furthermore, in this embodiment of the present invention, the packaged multiple busbars 1 are bundled together by multiple cable ties 6. The packaged multiple busbars 1 are arranged side by side and tightly attached together. The multiple cable ties 6 are arranged side by side in the direction of the busbars 1 and are perpendicular to the busbars 1.

[0019] Specifically, in this embodiment of the present invention, the two packaged busbars 1 are tied together by three cable ties 6, which are evenly distributed.

[0020] The beneficial effects of the technical solution provided by this utility model embodiment are as follows: This utility model embodiment provides a busbar packaging product, which uses a relatively thick pearl cotton sheet for packaging (providing better protection, but thicker sheets are difficult to wrap around the busbar, so an electrostatic film is used for fixation) and is waterproofed (the pearl cotton sheet has a cushioning effect, reducing the possibility of the waterproof film being punctured). Simultaneously, two pearl cotton end caps seal both ends of the busbar to prevent water and dust from entering; the electrostatic film is used to fix the pearl cotton sheet and the pearl cotton end caps and to seal the gap between the pearl cotton sheet and the pearl cotton end caps. The electrostatic film wrapping multiple layers at both ends also serves as a form of protection. Attached Figure Description

[0026] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] See Figure 1 and 3 -4. Example 1 provides a busbar packaging product, including the busbar 1 and its external packaging. The packaging includes a pearl cotton sheet 2 and two pearl cotton end caps 3. The outer sides of the pearl cotton sheet 2 and the pearl cotton end caps 3 are laminated with a waterproof membrane, and the thickness of the membrane is greater than or equal to 7 mm. The waterproof membrane can be a PET film (or other films), and it is very thin (usually less than 0.5 mm thick).

[0029] Two pearl cotton end caps 3 are respectively installed on both ends of the busbar 1. The inner side of each pearl cotton end cap 3 has a coaxially arranged insert 4 that mates with the busbar 1. This insert 4 is circular, with a diameter equal to the outer diameter of the busbar 1, and its inner edge rests against the end face of the busbar 1. The insert 4 is embedded into the end of the busbar 1 and is circular or polygonal in shape to mate with the busbar 1.

[0030] The pearl cotton sheet 2 is rectangular, covering the circumference of the busbar 1. Its length is equal to the length of the busbar 1 plus twice the thickness of the pearl cotton end cap 3. Its two ends overlap (the overlap length is preferably greater than 2cm) to form a cylinder that mates with the busbar 1. Its width is greater than the outer circumference of the busbar 1 to ensure the overlap, and its wide side is aligned with the outer side of the corresponding pearl cotton end cap 3. The cylinder and the two pearl cotton end caps 3 form a cylindrical structure.

[0031] The cylinder is wrapped with an electrostatic film 5 to fix the EPE foam sheet 2 and EPE foam end cap 3 to the busbar 1, while sealing the gap between the EPE foam sheet 2 and the EPE foam end cap 3. The electrostatic film 5 at the end of the cylinder is wound in multiple layers (e.g., 2-6 layers) to ensure the strength of the end (the most vulnerable area). It also covers the end of the EPE foam sheet 2 and the edge of the EPE foam end cap 3 to connect and seal them, thus fixing the EPE foam end cap 3 to the busbar 1. The electrostatic film 5 in the middle of the cylinder is spirally wound to fix the EPE foam sheet 2 to the busbar 1 and prevent the cylinder from unraveling. The spiral pitch is 30-60cm. The electrostatic film 5 can be a PET film (or other films), and it is very thin (usually less than 0.2mm thick).

[0032] Example 2

[0033] See Figure 4 Example 2 provides a busbar packaging product, whose structure is basically the same as that of Example 1. The difference is that the embedded part 4 in this example is circular, and its diameter is equal to the inner diameter of the busbar 1. The height of the end of the embedded part 4 is greater than or equal to 5mm.

[0034] Example 3

[0035] Example 3 provides a busbar packaging product, whose structure is basically the same as that of Example 2, except that the embedding part 4 in this example is a frustum-shaped structure with a larger inner part and a smaller outer part, so as to facilitate embedding.

[0036] Example 4

[0037] See Figure 3Example 4 provides a busbar packaging product with a structure basically the same as that of Example 1, except that the outer sides of the pearl cotton sheet 2 and the pearl cotton end cap 3 in this example are embossed to form a textured surface. Both are made of pearl cotton without any additives (such as solvent oil (to improve processing performance), specifically kerosene; experiments have shown that pearl cotton with additives will cause the friction area to turn black when in contact with aluminum alloy busbars). The textured surface provides better anti-collision performance and reduces slippage when the busbars 1 are stacked and bundled together.

[0038] Example 5

[0039] See Figure 3 Example 5 provides a busbar packaging product, whose structure is basically the same as that of Example 1, except that the raised bumps of the embossed pattern in this example are square and arranged in a square array, and the size of the raised bumps is 4-10mm*4-10mm.

[0040] Example 6

[0041] See Figure 2 Example 6 provides a busbar packaging product, the structure of which is basically the same as that of Example 1, except that: in this example, the packaged multiple busbars 1 are tied together by multiple cable ties 6, the packaged multiple busbars 1 are arranged side by side and tightly attached together, and the multiple cable ties 6 are arranged side by side in the direction of the busbars 1 and are perpendicular to the busbars 1.

[0042] Example 7

[0043] See Figure 2 Example 7 provides a busbar packaging product, the structure of which is basically the same as that of Example 6, except that: in this example, the two packaged busbars 1 are tied together by three cable ties 6, and the three cable ties 5 are evenly distributed.

[0044] Example 8

[0045] Example 8 provides a busbar packaging product, the structure of which is basically the same as that of Example 1, except that: in this example, the busbar 1 is an aluminum alloy busbar with a diameter of 150mm and a length of 15m. The thickness of the pearl cotton sheet 2 and the pearl cotton end cap 3 is 10mm, and the pitch of the spiral winding is 40-50cm.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
