Abstract

The invention discloses a multi-layer tubular bus structure which is characterized by comprising an outer tubular bus arranged on the outermost layer and an inner tubular bus concentric with the outer tubular bus, wherein a plurality of middle-layer tubular buses are arranged between the outer tubular bus and the inner tubular bus; the outer tubular bus, the middle-layer tubular buses. and the inner tubular bus are all of tubular structures; at least one first supporting piece is arranged between the inner wall of the outer tubular bus and the outer wall of the middle-layer tubular buses; and at least one second supporting piece is arranged between the inner wall of the middle-layer tubular buses and the outer wall of the inner tubular bus. The production technology of the multi-layer tubular bus structure is easy to implement, and the requirement for batch production can be met. According to different application requirements, the multi-layer tubular bus structure can be designed and bent into required angles and lengths for application.

Description

technical field [0001] The invention relates to the field of industrial electrical equipment, in particular to a multilayer tubular busbar structure. 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 busbars or multiple sets of strip-shaped busbars. Even the application of tubular busbars mostly appears as solid or single-layer tubular busbars. The strength of multi-layer busbars partially supported is limited by the application. 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. C...
