Description

Technical Field

[0001] The invention relates to the technical field of cast type bus duct, in particular to a cast type bus duct. Background Art

[0002] Cast bus duct, also known as cast bus or cast bus duct, is a highly efficient conductive equipment for power transmission and distribution. The following is a detailed analysis of cast bus duct: 1. Definition and composition Cast bus duct uses high-performance insulating resin (such as epoxy resin, etc.) to directly cast and seal the busbar (usually made of high-purity copper material) to form an integral current transmission channel. This design not only improves the insulation performance of the bus, but also enhances its mechanical strength and heat dissipation performance. The protection level of cast bus duct is usually high, such as reaching IP68, which means that it has good dust and water resistance. 2. Technical features Excellent insulation performance: Cast bus duct uses a special process to cast organic polymer insulating materials to form an integral insulation layer, which can effectively isolate current, prevent moisture and pollutants from invading, and ensure the normal operation of the power system. Stable current transmission capacity: Cast bus duct has good conductivity and can carry a large current load to meet the power needs of equipment such as motors and inverters. Good heat dissipation performance: Since the cast bus duct adopts an integral casting design, its heat dissipation area is relatively large, which is conducive to reducing the temperature rise of the line and improving the operating efficiency of the system. High mechanical strength: The overall structure of the cast bus duct is compact, with high mechanical strength, and can withstand certain external forces and impacts. Easy installation and maintenance: Compared with traditional bus products, the cast bus duct is more convenient in installation and wiring, and its structural design is also convenient for later maintenance and repair.

[0003] According to the patent number CN116979463B published on the China Patent Network, the present invention provides a fire-resistant and waterproof cast bus duct connector, including a bus connection assembly and an angle adjustment assembly, wherein the bus connection assembly includes two connection frames, a fire-resistant cast body and a plurality of connection conductors; the present invention uses a central rod to drive the insulating inner bushing to move by rotating the locking mechanism, and the moving insulating inner bushing drives the conductor connection plate to move, so as to adjust the angle between the connection conductor and the conductor connection plate, so as to adjust the bus duct connector to a direct connection type or a transfer type according to actual needs, thereby improving the application scope of the bus duct connector, and when there is an error in the height between the fire-resistant and waterproof cast bus ducts due to insufficient construction accuracy, the angle between the connecting conductor on the other side and the conductor connection plate is adjusted by rotating the locking mechanism on the other side, so as to form a height difference between the two connection frames, so as to adapt to fire-resistant and waterproof cast bus ducts of different heights, thereby improving the construction fault tolerance rate.
