Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to an intelligent power distribution cabinet. Background Technology

[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, and are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. 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 previous level of power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.

[0003] Currently, traditional manual switch-type distribution cabinets rely on manual operation to connect and disconnect circuits, which is not only time-consuming and labor-intensive, but also prone to safety accidents caused by misoperation. In addition, they lack real-time monitoring functions and cannot detect faults in time. Semi-automatic distribution cabinets, on the other hand, can achieve partial automation by introducing a simple relay control system, but still require a lot of manual intervention and do not have fault early warning functions.
