Description

Technical Field

[0001] This utility model relates to a metal-armored removable switch cabinet. Background Technology

[0002] Metal-clad withdrawable switchgear is a widely used device in medium- and high-voltage power distribution systems, primarily for the reception and distribution of electrical energy, as well as the control, protection, and monitoring of circuits. Metal-clad withdrawable switchgear includes switchgear side panels, switchgear doors, and switchgear linkage components. These linkage components enable the opening and closing of the switchgear doors. However, existing linkage components, especially their connection to the switchgear side panels and doors, generally exhibit weak stability under frequent door opening and closing. Particularly after long-term operation, the connections of the linkage components are prone to loosening or even detachment, affecting the stable opening and closing of the doors and posing safety hazards. Therefore, improvements and optimizations are proposed to address these issues. Utility Model Content
