Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinets, in particular to a low-voltage cabinet busbar connection structure. Background Art

[0002] The original dual power busbar solution for the low-voltage cabinet is complex and has many flip-up fastening bolts. In order to achieve the commonality of the left and right unit chamber busbars, the flip-up busbars are placed horizontally. However, the amount of copper busbars is greatly increased, and the vertical busbars need to be bent into an L shape before they can be connected to the flip-up busbars, which reduces the efficiency of the workshop processing and cannot meet the project bidding requirements. The connection structure of the busbar needs to be improved. Utility Model Content

[0012] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0013] Reference Figures 1 to 3 A low-voltage cabinet busbar connection structure includes a three-phase bridge bar 10, a three-phase flip bar 2 and a three-phase vertical bar 3. The B-phase flip bar of the three-phase flip bar 2 is in a Z shape, and the A phase and the C phase on both sides are connected by two Z-shaped flip bars. The A phase, the B phase and the C phase of the three-phase vertical bar 3 are in a vertical straight line shape. The three-phase bridge bar 10 and the three-phase vertical bar 3 are connected through the three-phase flip bar 2. In the utility model, by designing the three-phase flip bar 2 in a Z shape, wherein the A phase and the C phase are connected by two Z-shaped flip bars, replacing the previous horizontal shape, and the three-phase vertical bar 3 is designed to be a vertical straight line shape, replacing the previous L shape, it can be realized that the left and right unit chamber busbars are common, and at the same time the busbar structure is simple, reducing the overall copper consumption of the busbar and the number of subsequent bolt connections, and the three-phase flip bar 2 before the improvement is placed horizontally, so the three-phase vertical bar 3 needs to be bent into an L shape before it can be connected to it, which reduces the processing efficiency of the workshop.
