Problems solved by technology

[0002] In the prior art, there are many specifications of the busbar, such as circular, rectangular, tube, groove and other structural forms. The skin effect of the rectangular busbar is serious during the working process, and the heat dissipation effect is poor, which affects the overall equipment operation performance and safety.
At the same time, with the increase of current, the carrying capacity of the unit section of the busbar drops sharply, and the only way to maintain a certain temperature rise and increase the carrying capacity is to rely on increasing the cross-sectional area of ​​the busbar, so as to ensure the safe operation of the overall equipment, but at the same time Therefore, a large amount of waste of resources and a substantial increase in product production costs are caused.

Embodiment Construction

[0020] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can better understand the present invention and implement it.

[0021] Such as Figure 1-Figure 4 As shown, on the basis of a 120*10mm rectangular busbar, four 4*9mm rectangular holes are opened in the cross section, and the four holes are evenly distributed with an interval of 18mm, and a 4*5mm slot is opened on each side of the rectangular section. The distance between the grooves on both sides and the rectangular hole in the middle is 10mm, and the distance between the short sides of the six holes and the left and right sides of the rectangular section is 3mm.

[0022] Wherein, the above-mentioned four rectangular holes in the center of the section can be modified into rounded rectangular holes.

[0023] Among them, on the basis of the 120*10mm rectangular busbar, 8 circular holes with a diameter o...

Abstract

The invention discloses a rectangular perforating current-carrying busbar design. On the basis of a rectangular copper busbar, two long sides of the cross section of the rectangular busbar are maintained unchanged, uniform holes are formed inside the cross section of the busbar, and short sides of the rectangular cross section are grooved. According to the design, the materials are saved, the skin effect coefficient is reduced, the current-carrying capacity is basically not influenced, and the strength is qualified, so that the design is applied to engineering practice, the cost can be reduced effectively, and the incoming is increased.

Description

technical field [0001] The invention relates to the design of a rectangular perforated current-carrying busbar, belonging to the field of electric equipment. Background technique [0002] In the prior art, there are many specifications of the busbars, such as circular, rectangular, tube-shaped, groove-shaped and other structural forms. The rectangular busbar has serious skin effect and poor heat dissipation effect during the working process, which affects the operation performance and safety of the overall equipment. At the same time, with the increase of current, the carrying capacity of the unit section of the busbar drops sharply, and the only way to maintain a certain temperature rise and increase the carrying capacity is to rely on increasing the cross-sectional area of ​​the busbar, so as to ensure the safe operation of the overall equipment, but at the same time Therefore cause a large amount of waste of resources and a substantial increase in product production costs...
