Problems solved by technology

[0003] 1. The dynamic and thermal stability of the rectangular busbar is poor, and it needs to be strengthened by the busbar clamp;
[0004] 2. When the rectangular busbar is connected to the branch busbar or cables, it is necessary to measure and position on the rectangular busbar before punching holes, and the workload is heavy;
[0005] 3. When the low-voltage cabinet is reconstructed on site, if connection holes need to be added on the rectangular busbar, the busbar must be removed and re-drilled, which is very inconvenient;
[0006] 4. The carrying capacity of rectangular busbars is low, especially for high-current systems that use multiple rectangular busbars superimposed. When the number of superimposed busbars increases, the carrying capacity per unit cross-sectional area of ​​the busbars decreases

Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1-3 As shown, a new type of busbar includes two C-shaped busbar main bodies 1, and the two C-shaped busbar main bodies 1 are connected back to back through a connecting plate 2; the connecting plate 2 is perpendicular to the C-shaped busbar main body 1, and its Connect the middle part of two C-shaped busbar main bodies 1; the upper and lower parallel sides of one C-shaped busbar main body 1 extend to the other C-shaped busbar main body 1 but are not connected. This structure makes the busbar form an upward direction The lower two notches, the section length of such notches is shorter than the section length of connecting plate 2.

[0023] like figure 2 As shown, such a busbar looks like 4C, with notches on all four sides, which can realize the connection without holes on all sides. The cap part is in a rectangular shape...

Abstract

The present invention relates to a novel busbar. The busbar comprises two C-type busbar main bodies which are arranged back to back and are in connection arrangement through a connection plate, the upper and lower parallel sides of one of the C-type busbar main bodies is extended to the other C-type busbar main body without connection. The busbar is similar to a shape of 4C, and is provided with openings respectively facing four surfaces to achieve four-surface connection without holes the busbar overlap joint is very convenient, and splicing of a cabinet is convenient at the front and at theback of the cabinet.

Description

technical field [0001] The invention relates to a busbar for low-voltage complete equipment, and specifically discloses a novel busbar. Background technique [0002] The main busbar of the conventional low-voltage cabinet is rectangular, and this rectangular busbar has the following disadvantages: [0003] 1. The dynamic and thermal stability of the rectangular busbar is poor, and it needs to be strengthened by the busbar clamp; [0004] 2. When the rectangular busbar is connected to the branch busbar or cables, it is necessary to measure and position on the rectangular busbar before punching holes, and the workload is heavy; [0005] 3. When the low-voltage cabinet is reconstructed on site, if connection holes need to be added on the rectangular busbar, the busbar must be removed and re-drilled, which is very inconvenient; [0006] 4. The carrying capacity of rectangular busbars is low, especially for high-current systems that use multiple rectangular busbars superimposed...
