Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a power distribution cabinet with a protection mechanism. Background Art

[0002] The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), and metering cabinet (box). It 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.

[0003] The patent document with announcement number CN215299834U discloses a low-voltage distribution cabinet with an isolation protection mechanism, which includes: an outer cabinet body and an isolation mechanism, wherein the isolation mechanism includes an electric cylinder, an isolation plate and an isolation curtain. The device adopts the form of upper exhaust and lower air intake, so that the heat generated in the distribution cabinet can be discharged to the outside of the cabinet body to the maximum extent, and an air detector is arranged inside the air inlet slot of the traditional distribution cabinet to detect the air quality of the make-up air entering the cabinet body in real time. When the set value is exceeded, the electric cylinder drives the isolation plate to block the air inlet slot to prevent external impurities such as dust or water droplets from entering the cabinet body, affecting the hygiene and safety of electrical components in the distribution cabinet. The isolation curtain arranged on the front side of the cabinet isolates the electromagnetic waves generated by the electrical components to prevent radiation interference.

[0004] However, the above patent document is not convenient for adjusting the height of the cabinet during use, which leads to water easily entering the cabinet when the rainfall is heavy.
