Abstract

The application discloses a high-voltage transmission copper bar with a honeycomb structure and a heat dissipation function, and relates to the technical field of heat dissipation copper bars. The copper bar body is provided with a butt joint hole, a butt joint thread, a heat dissipation hole and a heat dissipation groove. The butt joint hole and the butt joint thread provide a mounting butt joint interface. When the ordinary copper bar is used for high-voltage and large-current transmission, the copper bar has no heat dissipation structure, and generates a large amount of heat. When abnormal current works, the copper bar generates a large amount of heat, which easily leads to high-temperature ablation. The multiple honeycomb-shaped heat dissipation holes formed on the copper bar can greatly increase the heat dissipation area in the smallest volume space, solve the heat generation problem of the copper bar in the subsequent use process, and additionally leave multiple grooves on the surface of the copper bar to further increase the heat dissipation area. The application has the advantages of reasonable and simple structure, durability, low cost, obvious heat dissipation effect, and greatly improved characteristics of poor heat dissipation of the ordinary copper bar during work, easy high-temperature ablation and loss during abnormal current work, and is very helpful to improve the use quality.

[0002] During the use of the conductive slip ring under the special working condition of high voltage, insulation design is required between the conductive bodies and between the conductive bodies and the ground. With the continuous improvement of industrial product demand, the power load is getting larger and larger, and the current and voltage of the power transmission conductor are continuously rising. How to improve the safety technology under high-voltage and large-current load and avoid the long-term working temperature rise and heating phenomenon, which further leads to the aging of the insulation material or the melting of the conductor, has become a technical problem. The ordinary heat dissipation copper bar has a simple structure and is often not designed with a special heat dissipation structure, and the material selection is also improper. The above-mentioned phenomenon often leads to poor voltage and current resistance of the slip ring, and the long-term working temperature rise and heating phenomenon leads to the aging of the insulation material and causes the short circuit problem, and even causes a fire accident, so the safety is not high, and the product quality reliability is insufficient. Especially for large-current transmission, the heat dissipation is extremely critical to the reliability of high-temperature work. The ordinary heat dissipation copper bar has a simple design structure, poor heat dissipation leads to aging and short circuit problems, and when an additional heat dissipation system is required, the heat preservation effect is poor, the cost is high, and the use is not convenient.
