Description

Technical Field

[0001] The utility model belongs to the technical field of power distribution cabinets, in particular to a power distribution control cabinet. Background Art

[0002] A distribution cabinet is a general term for a motor control center. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits; motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy 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. Usually, when the distribution cabinet is in use, it will be placed against the wall, and the electrical equipment in the distribution cabinet is usually installed on the back plate of the inner wall of the cabinet. This will cause the back plate of the distribution cabinet to receive more heat, and the cabinet against the wall will seriously affect its heat dissipation effect. In addition, due to its large size during use, the common distribution cabinet has the problem of being inconvenient to move. For this reason, the present application proposes a distribution control cabinet. Utility Model Content
