Description

Technical Field

[0001] The invention relates to the technical field of power distribution cabinets, and in particular to an outdoor power distribution cabinet. Background Art

[0002] A distribution cabinet (also called a distribution panel, distribution box, distribution cabinet, etc.) is an important device in the power system, mainly used to receive, distribute and control the flow of electricity. It is usually used in industrial, commercial buildings, residential and other places to ensure the stable supply of electricity, ensure the safe operation of equipment, and provide necessary protection functions for the equipment. A distribution cabinet is generally composed of multiple electrical components, such as circuit breakers, disconnectors, contactors, ammeters, voltmeters, etc.

[0003] The patent application document with the publication number CN116581667A discloses an adaptive outdoor power distribution cabinet, including a cabinet, multiple support columns, multiple rain shields, multiple first heat dissipation holes, two groups of offset plates, a rain storage trigger box and an ejection mechanism. Multiple support columns are arranged at the lower end of the cabinet, multiple rain shields and first heat dissipation holes are fixedly arranged on both sides of the cabinet, each first heat dissipation hole is correspondingly arranged at the lower end of a rain shield, two groups of offset plates are respectively movably arranged on the inner side of the cabinet where the rain shield is installed through guide rails, and the offset plate is provided with multiple first offset holes corresponding to the first heat dissipation holes. On sunny days, the first heat dissipation hole can be aligned with the first offset hole to achieve effective heat dissipation of the cabinet; on rainy days, the ejection mechanism is pressed down by the rain storage trigger box, and rainwater can be temporarily stored in the rain storage trigger box. The greater the rainfall, the greater the storage capacity in the rain storage trigger box, and the greater the degree to which the rain storage trigger box presses the pressing rod downward, the smaller the overlap between the first heat dissipation hole and the first offset hole, so that the size of the first heat dissipation hole can be automatically adjusted according to the amount of rainfall, thereby preventing rainwater from entering the cabinet and automatically adjusting the waterproof capability.

[0004] The solution also has the following problems: although it can prevent rainwater from entering the cabinet, the premise of rain protection is that the cabinet door is closed. When a line rescue operation is encountered on a rainy day and it is necessary to operate the inside of the distribution cabinet, the operation can only be carried out by opening the cabinet door. After the cabinet door is opened, rainwater will still be swept into the cabinet, which will inevitably cause rainwater to enter when operating the distribution cabinet on rainy days, which is not conducive to the operation and maintenance of the distribution cabinet on rainy days. Summary of the invention
