Description

Technical Field

[0001] The present invention belongs to the technical field of bus duct bends, and specifically relates to a bus duct bend unit that is easy to install. Background Art

[0002] After 20 years of development, various solutions for intensive busbars have gradually stabilized. In order to adapt to the market's higher requirements for delivery and installation conditions, mainstream manufacturers in the industry have begun to design their own standardized products.

[0003] Existing bus duct products still follow the early manufacturing process, where on-site technicians first measure the direction, send back the drawings for technical analysis, and then design and order manufacturing. When encountering non-standard units of elbows, the long design and processing cycle will greatly limit the customer's delivery time. In order to better adapt to the market environment, a standardized solution is needed to support it. Utility Model Content

[0004] In order to solve the above problems, this paper proposes a bus duct bending unit that is easy to install. Two bus ducts are connected by a bus connector. The ends of the two bus ducts are vertically butted against each other. The outer side of the vertical butt end of the bus duct is provided with a beveled side ear. The inside of the bus duct is provided with a beveled conductor. The outer contour of the beveled side ear is larger than the end of the beveled conductor. The beveled side ear is an end double-cut beveled side ear plate. The lower side of the end of the beveled side ear is a connecting bevel. The upper side of the connecting bevel is provided with a vertical bevel. The beveled conductor is provided at one end corner. The beveled edge is parallel to the connecting beveled edge, the connecting beveled edge is perpendicular to the vertical beveled edge, the connecting beveled edge of the beveled side ear is connected to the outer sides of the left and right sides of the busbar connector, and the vertical beveled edge of the beveled side ear is flush with the upper and lower sides of the busbar connector. Starting from the most common vertical bend, a standardized design improvement is carried out, so that the vertical bend of the new solution can be directly connected through an ordinary connector, and there is no need to weld the conductor and the shell profile like the previous vertical bend, which greatly improves the manufacturing efficiency of the product.

[0005] The bus duct comprises a bus body, a beveled conductor and beveled side ears. A plurality of beveled conductors are arranged in parallel on the inner side of the bus body, and beveled side ears are arranged on the front and rear sides of the end of the bus body.

[0006] The busbar connector is a universal straight-through connector. The outer contour of the busbar connector is rectangular. The left and right sides of the busbar connector are provided with plug-in connecting ports. The center of the busbar connector is provided with a fastening bolt. The use of a universal busbar connector can achieve right-angle bending and turning, thereby minimizing the difficulty of production.

[0007] The beveled side ear is a pentagonal sheet metal structure. One side of the beveled side panel is provided with a sheet metal bent right-angled edge, and the other side of the beveled side panel is provided with a connecting bevel and a vertical bevel. The connecting bevel is an equilateral forty-five-degree bevel. A vertical bevel is provided at the side of the beveled side panel at the upper end of the connecting bevel. The vertical bevel and the connecting bevel are perpendicular to each other. The angle of the beveled edge of the beveled conductor is forty-five degrees. The end length of the beveled conductor at one end of the beveled edge is greater than the vertical end of the beveled conductor. The vertical bevel on site is passed through two sections of special-shaped straight lines and a connector to quickly realize the installation of the bend. For occasions where the on-site space is small and ordinary bends cannot be transported, the new solution is more convenient for disassembly and installation, which effectively reduces the difficulty of installation and construction.

[0008] Beneficial effects:

[0009] Starting with the most common vertical bend, we made standardized design improvements so that the vertical bend of the new solution can be directly connected through ordinary connectors. Unlike previous vertical bends, there is no need to weld conductors or shell profiles, which greatly improves the manufacturing efficiency of the product.

[0010] The same new connector vertical bend design can quickly realize the installation of the bend on site by using two special-shaped straight lines and a connector. For occasions where the on-site space is small and ordinary bends cannot be transported, the new solution is more convenient for disassembly and installation, effectively reducing the difficulty of installation and construction.
