AI Technical Summary
The exposed bolt connection points of traditional central cabinets result in poor cabinet aesthetics, insufficient protection, and inconvenience in cabinet assembly.
The bolt connection is moved inside the cabinet. By designing a plane that bends inward at 90 degrees at the top and bottom ends of the side panel and drilling holes in the plane, the bolts pass through these holes from the inside to make the connection, thus achieving internal fixation.
It improves the aesthetics and protection of the cabinet, simplifies the parallel operation with other types of medium-voltage switchgear, and ensures the stable operation of the power system.
