Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage complete switchgear, in particular to a low-voltage switch cabinet drawer cabinet. Background Art

[0002] Drawer cabinets are a key component of low-voltage switchgear. Their design encompasses core components such as the drawers, molded case circuit breakers, and operating mechanisms for wire connections. Currently, wire connection methods in drawer cabinets have limitations, such as insufficiently compact and standardized connections between wires, which impacts the reliability and safety of the overall equipment.

[0003] In existing low-voltage switchgear drawer cabinets, the connection between the wires and the molded case circuit breakers is usually made through copper busbars. However, the connection between the copper busbars often lacks a reasonable layout, resulting in a loose arrangement of the horizontal and vertical directions of the wire connections. This not only affects the aesthetics of the wire connection, but may also cause poor heat dissipation at the connection point, affecting the operating efficiency and safety of the equipment. Moreover, in low-voltage complete switchgear, the copper busbars in the drawer cabinet circuit are all spliced ​​at multiple points. The multi-point splicing method will increase the assembly period. At the same time, too many splicing points will increase the equipment failure rate.

[0004] For this purpose we offer a low-voltage switchgear drawer cabinet. Utility Model Content
