Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, and more specifically to a sealed moisture-proof outdoor ring network cabinet. Background Art

[0002] Ring network cabinet is a group of electrical equipment installed in metal or non-metal insulation cabinet or assembled into interval ring network power supply unit. Its core part adopts load switch and fuse. It has the advantages of simple structure, small size, low price, improved power supply parameters and performance, and power supply safety. It is widely used in distribution stations and box-type substations in urban residential areas, high-rise buildings, large public buildings, factories and enterprises and other load centers. Normal outdoor ring network cabinet is installed on the ground or roof, where moisture is easy to accumulate. Traditional outdoor ring network cabinet does not have moisture-proof function. External humid air can easily enter the ring network cabinet from the air inlet. Humid air can easily corrode the internal structural components of the ring network cabinet and cause short circuit of internal electrical equipment, shortening the normal service life of the ring network cabinet.

[0003] As disclosed in patent No. 202021000799.1, a moisture-proof device for an outdoor ring network cabinet is provided with air holes around the bottom of the inner cavity of the ring network cabinet body, a fixed frame is fixedly connected to the bottom of the ring network cabinet body, and a moisture-proof mechanism is arranged on the top of the ring network cabinet body. Through the cooperation of the moisture-proof mechanism, it is convenient for the user to dry the air drawn in by the blower, prevent the external humid air from entering the inner cavity of the ring network cabinet body, and avoid the humid air from corroding the inner cavity of the ring network cabinet body. Through the cooperation of the motor and the fan blades, the humid air in the inner cavity of the ring network cabinet body can be extracted, and the content of humid air in the inner cavity of the ring network cabinet body can be reduced, thereby enhancing the moisture-proof effect of the ring network cabinet body. However, although this structure can prevent moisture from entering during the air intake process, the traditional box door cannot achieve a sealing effect. During long-term use, the sealing strip will be deformed, resulting in humid gas entering the box door, affecting the overall moisture-proof performance.

[0004] Therefore, how to provide a ring main unit that can enhance the moisture-proof performance of the cabinet door is an urgent problem to be solved by those skilled in the art. Utility Model Content
