Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinets, in particular to an intelligent power distribution cabinet with good sealing performance. Background Art

[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the terminal equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in occasions where the load is relatively dispersed and there are fewer circuits; the motor control center is used in occasions where the load is concentrated and there are more circuits. They distribute the electric 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. The intelligent distribution cabinet is also a precision distribution cabinet. It is a distribution cabinet for the energy terminal of the data center computer room that comprehensively collects all energy data.

[0003] Distribution cabinets can be used for power distribution. Existing intelligent distribution cabinets have poor sealing performance for the cabinet body and cabinet doors. When used outdoors or in a working environment exposed to water for a long time, it is easy for ambient water to seep into the cabinet body and cause circuit short circuits. In addition, when the distribution cabinet catches fire due to short circuits or other reasons, it is difficult for surrounding personnel to detect and deal with it in time, which poses a potential fire risk. In addition, if there is water accumulation when the distribution cabinet falls to the ground, the cabinet body will also be soaked in water. Summary of the Invention
