Technical Field

The utility model relates to the technical field of electrical equipment, in particular to a building control distribution cabinet.

Background Art

The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet, which is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits; the motor control center is used in places where the load is concentrated and there are more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load. Including the first-level distribution equipment, the second-level distribution equipment and the final distribution equipment, the first-level distribution equipment is collectively referred to as the power distribution center. They are centrally installed in the substation of the enterprise to distribute the power to the lower-level distribution equipment in different locations. This level of equipment is close to the step-down transformer, so the electrical parameters are required to be higher and the output circuit capacity is also larger. The second-level distribution equipment is a general term for the power distribution cabinet and the motor control center. The power distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits; the motor control center is used in places where the load is concentrated and there are more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load. The final distribution equipment is generally called lighting power distribution box. They are far away from the power supply center and are decentralized small-capacity distribution equipment.
