Description

Technical Field

[0001] The utility model specifically relates to the technical field of bus ducts, in particular to a bus duct with a heat dissipation mechanism. Background Art

[0002] Bus duct is a closed metal device composed of copper and aluminum busbars, which is used to distribute high power to various components of the distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects.

[0003] After searching, it is found that the bus duct in the prior art is typically disclosed in CN208753923U, which includes a trough body, the inner wall of the trough body is provided with a plurality of installation grooves for inserting copper sheets, the installation groove has a notch facing the trough body cavity, a limit plate is provided at the notch, the depth of the installation groove is greater than the thickness of the copper sheet, and the two ends of the installation groove are slidably connected with a clamping column, and the end of the clamping column extends into the installation groove and is provided with a clamping sheet. When installing the copper sheet, the clamping column is slid outward, and the clamping column drives the clamping sheet to the bottom of the installation groove. The size of the installation groove is large, which is convenient for inserting the copper sheet. After the copper sheet is inserted, the clamping column is slid inward, and the clamping sheet presses the copper sheet, and the copper sheet contacts the limit plate, and the copper sheet is fixed. Through the arrangement of the clamping column and the clamping sheet, the size of the installation groove can be greater than the thickness of the copper sheet, which is convenient for the installation of the copper sheet. After the installation is completed, the clamping sheet presses and fixes the copper sheet, and the copper sheet is not easy to slide and has good stability.

[0004] In summary, when a bus duct in the above case is connected to electricity and working, the internal copper sheet will generate a lot of heat during long-term operation. This heat will cause the temperature of the bus duct itself to be too high. Relying solely on ventilation ducts to dissipate heat is far from achieving a good heat dissipation effect, resulting in aging of the insulator in the bus duct. Utility Model Content
