Description

Technical Field

[0001] The utility model belongs to the technical field of heat dissipation of power distribution cabinets, and in particular relates to a power distribution cabinet for a power substation. Background Art

[0002] A distribution cabinet (box) is a device used for power distribution and control in a power system. It is usually made of metal, closed or semi-closed, and installed in the power room of a building or industrial facility. The main function of a distribution cabinet is to control and monitor the power supply while protecting the circuit from faults and abnormal conditions.

[0003] The distribution cabinet usually generates a lot of heat during use. The heat inside the distribution cabinet will affect the normal operation and service life of the internal components. It is necessary to continuously transport fresh air from the outside into the distribution cabinet to discharge the heat inside the distribution cabinet.

[0004] In the prior art, while delivering fresh air to the interior of the distribution cabinet, a filtering mechanism is required to filter the dust in the air so that the dust does not interfere with the normal operation of the distribution cabinet. However, after the filtering mechanism has been used for a certain period of time, a large amount of dust is easily adsorbed on the surface. The dust can cause blockage inside the filtering mechanism and affect the air flow rate, thereby slowing down the speed at which heat dissipates from the interior of the distribution cabinet, causing the temperature inside the distribution cabinet to be too high.

[0005] Therefore, in view of the above technical problems, it is necessary to provide a distribution cabinet for a power substation.

[0006] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.
