Embodiment Construction

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

[0028] The following uses the three-layer tubular bus structure as an example to illustrate the multi-layer tubular bus structure of the present invention. Of course, the present invention is not limited to the three-layer tubular bus structure, and may also be a two-layer tubular bus structure or more than three layers Tubular busbar structure. The multi-layer linear tubular busbar uses copper pipes of different diameters for multi-layer layout. According to the product application occasion and current carrying size and other factors, the number of layers can be adjusted and configured from 1 to N layers.

[0029] see figure 1 and figure 2 , the three-layer linear tubular busbar shown in the figure includes three layers of linear tubular busbars arranged from the inside to the outer layer, that is, the inner layer linear tubular busbar 10, ...

Abstract

The invention discloses a multilayer tubular busbar structure. The multilayer tubular busbar structure is characterized by comprising at least two layers of tubular busbars which are sleeved with eachother from inside to outside and at least two positioning plates; the positioning plates are arranged at the end parts of all the tubular busbars and are used for positioning each layer of tubular busbar. The multi-layer tubular busbar structure mode can meet the requirements of large current, high current carrying and electric field optimization. since the surface area of the multi-layer tubularbusbar structure is increased, the problem of large current carrying is solved; air convection is realized by utilizing gaps of the structure; and the electric field performance is optimized by meansof the pipe shape and the arc shape of the multi-layer tubular busbar structure. An alternative scheme is added for busbar selection of large-current-carrying, high-heat-dissipation and electric field optimization application products. The multi-layer tubular busbar is mature in production process, flexible in splicing and uniform in 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 structure in the market is mostly rectangular strip busbar. In the industry, especially in the electric power industry, various components with relatively large current-carrying requirements are mostly connected with large copper bars or multiple sets of strip-shaped busbars. With the advancement of technology and the times, switch cabinets and many electrical products are gradually developing towards miniaturization. Use and environment to make trade-offs. With the continuous breakthrough of technology and technology at home and abroad, the structure of busbars has also been diversified. Contents of the invention [0003] The techni...
