Abstract
Description
Technical Field
[0001] This utility model relates to the field of power transmission technology, specifically to an aluminum alloy busbar casing. Background Technology
[0002] Busbar trunking is an enclosed metal device composed of copper or aluminum busbars, used to distribute high power to various components in a distributed power system. Due to its efficient power transmission capacity, busbar trunking is gradually replacing traditional cables in indoor low-voltage power transmission projects. With the rapid development of modern facilities such as high-rise buildings and large factories, electricity demand has surged. Traditional cables, due to their insufficient high-current transmission capacity, cannot meet the needs of high-load scenarios, while the parallel use of multiple cables leads to complex installation and low construction efficiency, making busbar trunking a superior solution. Currently, busbar trunking is widely used in developed countries and Hong Kong and Macau. A typical enclosed busbar trunking consists of a metal shell, conductor bars, insulation materials, and accessories. The metal shell is mostly made of steel, aluminum alloy, or a steel-aluminum hybrid material. A typical enclosed busbar trunking can be adapted to three-phase four-wire or five-wire power distribution systems with AC 50Hz, rated voltage 380V, and rated current 250A-6300A.
[0003] However, existing busbar trunking technology still faces significant drawbacks: weak cover plate support structures lead to easy deformation of the busbars, resulting in insufficient long-term stability; limited heat dissipation area of side plates causes heat accumulation, affecting system operating efficiency and safety; simultaneously, traditional steel shells are heavy, prone to corrosion, increasing installation and maintenance costs and hindering lightweight design. To address these issues, there is an urgent need to develop a new type of busbar trunking shell that combines high-strength support, efficient heat dissipation, and lightweight characteristics to overcome existing technological bottlenecks. Summary of the Invention
[0004] To address the problems of weak support, severe deformation, small heat dissipation area of side plates, uneven heat dissipation, heavy weight, and susceptibility to corrosion in existing busbar trunking shells, this utility model provides an aluminum alloy busbar trunking shell.
