Description

Technical Field

[0001] The utility model relates to a rainproof power distribution cabinet, belonging to the technical field of power distribution cabinets. Background Art

[0002] The distribution cabinet is divided into power distribution cabinet and lighting distribution cabinet. It is the final equipment of the power distribution system and 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] Due to the limitations of on-site conditions, the distribution cabinet will inevitably be placed in an open-air environment. A common solution is to use a distribution cabinet with a higher protection level or to build a rainproof shed for the distribution cabinet. However, distribution cabinets with a higher protection level often do not have good heat dissipation performance. In order to solve the heat dissipation problem, the method adopted refers to the means disclosed in application number 201810842713.0, that is, a row of horizontal air slots arranged in a vertical direction are arranged at the lower positions on the left and right sides of the box, and a rainproof cover is punched out on the outside of the slot. Although this structure achieves a certain heat dissipation purpose, since the air slots are set too low, the heat inside the box cannot be dissipated in time, and the heat dissipation effect is poor.
