Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinet components, and particularly relates to an adjustable power distribution cabinet housing. Background Technique

[0002] Power distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), and are the terminal equipment of the power distribution system. Power distribution cabinets are the general term for motor control centers. Power distribution cabinets are used in occasions where the load is relatively dispersed and the number of circuits is small; motor control centers are used in occasions where the load is concentrated and the number of circuits is large. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby loads. This level of equipment should provide protection, monitoring, and control for the load. At present, power distribution cabinets are composed of multiple components, including power distribution cabinet housings.

[0003] The following problems still exist when the existing power distribution cabinet housing is in use: Most of the power distribution cabinet housings adopt an integral rectangular housing structure design. The front end of the rectangular housing is open, but when facing different installation space requirements inside and outside the housing, due to the fixed structure design of the overall power distribution cabinet housing, it cannot be well adapted.
