Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] The multi-layer tubular busbar structure of the present invention is described below by taking the three-layer tubular busbar structure as an example. Of course, the present invention is not limited to the three-layer tubular busbar structure, and can also be a two-layer tubular busbar structure or more than three layers. Tubular busbar structure. The multi-layer linear tubular busbar uses copper tubes of different diameters for multi-layer arrangement. The number of layers can be adjusted from 1 to N layers according to factors such as product application and current-carrying size.

[0029] see figure 1 and figure 2 , The three-layer linear tubular busbar shown in the figure includes three linear tubular busbars arranged from the inside to the outer layer, namely the inner layer linear tubular busbar 10, the middle layer linear tubul...

Abstract

The invention discloses a multi-layer tubular busbar structure, which is characterized by comprising at least two layers of tubular busbars arranged from the inside to the outside and at least two positioning plates, wherein the positioning plates are installed at the ends of all the tubular busbars, Position each layer of tubular busbars. The multi-layer tubular busbar structure of the present invention can meet the requirements of large current, high current carrying and electric field optimization. The large current-carrying problem is solved by increasing the surface area; the air convection is realized by using the gap of its structure; the optimized electric field performance is solved by using the tube shape and arc shape. Adds an alternative to busbar selection for high current carrying, high heat dissipation, electric field optimized applications. The multi-layer tubular busbar has mature production technology, flexible splicing and uniform electric field distribution.

Description

technical field [0001] The invention belongs to the field of industrial electrical equipment, and in particular relates to a multi-layer tubular busbar structure for satisfying large current carrying capacity, realizing electric field optimization and improving heat dissipation effect. Background technique [0002] At this stage, the busbar structures on the market are mostly rectangular strip busbars. In industry, especially in the power industry, large copper bars or multiple sets of strip-shaped bus bars are superimposed and connected between various components with relatively large current-carrying requirements. With the advancement of technology and the times, switch cabinets and many electrical products are gradually developing in the direction of miniaturization. The original layout and arrangement method are difficult to take into account many factors such as current carrying, heat dissipation, material saving, electric field and so on. Use and environment to make t...
