Description

Technical Field

[0001] This utility model relates to the field of switchgear, and in particular to a modular component assembly rack for low-voltage switchgear. Background Technology

[0002] Low-voltage switchgear is a core piece of equipment in power systems used for power distribution, control, and protection. It contains various modular components such as circuit breakers, busbars, relays, and instruments. These modular components are typically mounted on assembly racks inside the switchgear. The assembly racks have mounting plates, and the modular components have slots that allow them to be secured to the mounting plates for installation and use.

[0003] Existing assembly racks cannot adjust the spacing between mounting plates. Generally, the mounting plates are fixed to the surface of the rack, resulting in a fixed spacing. This leads to problems because the modular components vary in size, causing either insufficient spacing for installation or excessive spacing, resulting in wasted internal space in the low-voltage switchgear, reduced practicality and applicability, inconvenience in use, and a lack of cable management functionality. Furthermore, the modular components in the low-voltage switchgear require wire connections, resulting in numerous and tangled cables, impacting installation efficiency, maintenance, and ease of use. To address these issues, we propose a modular component assembly rack for low-voltage switchgear. Utility Model Content
