Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a top plate component of a low-voltage power distribution cabinet. Background Art

[0002] Low-voltage distribution cabinets are suitable for AC power users such as power plants, factories and mines, heavy engineering machinery (port cranes, mining machinery, material conveying machinery, etc.). AC low-voltage distribution cabinets are motor control centers used for power transmission, distribution and power conversion. Currently, low-voltage distribution cabinets on the market are usually integrated. When installing or repairing electrical components inside the low-voltage distribution cabinet, due to the small internal space of the low-voltage distribution cabinet, its top plate is usually welded and fixed during production and cannot be opened. It can only be operated from the front door of the low-voltage distribution cabinet, which is not convenient for staff to install or repair electrical components in the low-voltage distribution cabinet.
