Variable volume switch board
Technical Field
The invention relates to the technical field of power distribution cabinets, in particular to a variable-volume power distribution cabinet.
Background
The distribution cabinet (case) is a final-stage device of a distribution system and is divided into a power distribution cabinet (case), a lighting distribution cabinet (case) and a metering cabinet (case). The power distribution cabinet is a general name of a motor control center. The power distribution cabinet is used in the occasions with dispersed loads and less loops; the motor control center is used for occasions with concentrated loads and more loops. They distribute the power of a certain circuit of the upper-level distribution equipment to the nearby loads. This level of equipment should provide protection, monitoring and control of the load.
