Description

Technical Field

[0001] The utility model relates to the field of power distribution cabinets, in particular to a power distribution cabinet with moisture-proof and explosion-proof functions. Background Art

[0002] The distribution cabinet is a device used for electric energy distribution, control and protection. It is usually used to introduce electricity from power stations or main power sources into buildings or industrial facilities, and then distribute it to various circuits. It is a key component in the power system. It helps to ensure the safe, efficient and reliable supply of electric energy to various electrical equipment. The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the final equipment of the distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in occasions with relatively dispersed loads and fewer circuits. The motor control center is used in occasions with concentrated loads and more circuits. The distribution cabinet will generate heat during operation. In order to quickly dissipate the heat of the distribution cabinet, a cooling fan is generally installed in the distribution cabinet to dissipate the heat of the distribution cabinet. However, during the heat dissipation process, a large amount of outside air will enter the cabinet, which may cause the distribution cabinet to be damp.

[0003] According to Chinese patent number CN210201289U, a power distribution cabinet with moisture-proof function includes a power distribution cabinet body, a rotating heat dissipation mechanism is arranged on the lower inner surface of the power distribution cabinet body, a cabinet door is arranged on the front inner surface of the power distribution cabinet body, a moisture-proof mechanism and a buckle are arranged on one side of the outer surface of the cabinet door, the moisture-proof mechanism is located on one side of the buckle, a wiring trough combination is arranged on the inner surface of one side of the power distribution cabinet body, and an intelligent monitoring device is arranged on the rear inner surface of the power distribution cabinet body. In the above patent scheme, the interior of the cabinet is treated with moisture-proof agent, and the moisture-proof agent needs to be replaced regularly. If it is not replaced in time, it is easy to cause the cabinet to be damp, causing the electrical equipment to be damp. For this reason, we propose a power distribution cabinet with moisture-proof and explosion-proof function to solve the above problems. Utility Model Content
