AI Technical Summary

Technical Problem

The fixed width and height of the busbar connections in existing low-voltage switchgear make it difficult to flexibly adapt to different current ratings of drawers from various manufacturers, affecting the applicability of construction and renovation.

Method used

The design employs an adjustable first and second mounting plate, combined with a flexible conductor, to achieve two-dimensional position adjustment of the busbar connector within the backplane plane. This ensures that the busbar connector is accurately aligned with the vertical busbar inside the cabinet. Furthermore, the flexible conductor compensates for displacement changes, replacing the traditional rigid copper busbar to guarantee the reliability of the electrical connection.

Benefits of technology

It enables flexible adjustment of the busbar connector in a two-dimensional plane of length and height, adapting to drawer structures of different current levels, avoiding incompatibility issues caused by differences in structural dimensions, improving connection reliability and safety, and eliminating the risk of poor contact and equipment damage caused by installation stress.

Abstract

This invention relates to the field of power distribution equipment technology and discloses a drawer-type low-voltage switchgear, comprising: a cabinet body with a receiving cavity; a drawer housing disposed within the receiving cavity; the drawer housing includes a bottom plate, a front plate, and a back plate, the front plate being disposed on one side of the bottom plate and the back plate on the other side of the bottom plate; a first mounting plate adjustablely disposed on the back plate along a first direction; a second mounting plate adjustablely disposed on the first mounting plate along a second direction, wherein the first direction and the second direction are perpendicular to each other in the plane of the back plate; a molded case circuit breaker disposed within the drawer housing; an operating mechanism disposed within the drawer housing and connected to the molded case circuit breaker; a busbar connector disposed on the second mounting plate; and a flexible conductor electrically connecting the molded case circuit breaker and the busbar connector. By adjusting the positions of the first and second mounting plates, the busbar connector can be accurately aligned with the vertical busbars within the cabinet, avoiding the problem of incompatibility due to differences in structural dimensions, allowing for immediate use upon adjustment and meeting the requirements of adaptive installation.
