Description

Technical Field

[0001] The utility model belongs to the technical field of power distribution cabinets, and in particular relates to a dust and moisture proof device for a power distribution cabinet with good protection effect. Background Art

[0002] The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), and metering cabinet (box). It is the final equipment of the power distribution system. The distribution cabinet 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, and 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. Many distribution cabinets are installed outdoors, and dust will fall into the inside of the distribution cabinet through the heat dissipation holes. When it rains or the air is humid, water and moisture are easily intruded into the distribution cabinet.

[0003] However, the existing distribution cabinets are not equipped with effective dust and moisture-proof devices. Dust is blown into the distribution cabinet through the heat dissipation holes. Excessive dust accumulation can easily affect the ventilation and heat dissipation of the heating elements, causing air circulation obstruction, thereby causing the insulation of the equipment to decrease due to heat. In addition, when the air is too humid, moisture will enter the distribution cabinet, causing damage to the electrical components and affecting the normal use of the distribution cabinet. Therefore, it is very necessary to design a dust and moisture-proof device for the distribution cabinet that is highly practical and has good protection effect. Utility Model Content

The controller is arranged inside the distribution box, and the dehumidifier 12 is electrically connected to the hygrometer 13 through the controller. The aluminum oxide film inside the hygrometer 13 can absorb water from the surrounding gas and cause changes in its own capacitance and resistance values. The amplitude of the change is used to represent the relative humidity of the surrounding gas. When the humidity reaches a certain value, the controller receives a signal to start the dehumidifier 12. The dehumidifier 12 sucks in humid air from the air inlet through the operation of the internal fan, evaporates it through the evaporator, and absorbs the moisture in the air on the aluminum sheet, so that the moisture becomes dry air. Finally, the heat is dissipated through the condenser, and the dry gas is blown out from the air outlet. The moisture can flow out from the outlet pipe to the outside of the distribution cabinet. The partition can prevent the moisture and dry gas from mixing and guide the dry gas to flow downward.

[0020] The cabinet body 3 includes a first support plate 31, a second support plate 32, a third support plate 33 and a cabinet door 35. The first support plate 31 and the second support plate 32 are parallel to each other. The first support plate 31 and the second support plate 32 are both provided with interlayers and the rear sides of the interlayers are open.

[0024] Heat dissipation holes 34 are provided in the middle of the first support plate 31 and the second support plate 32. The heat dissipation holes 34 are used to enhance the flow of air between the inside and outside of the power distribution cabinet, dissipate the generated heat, protect the components inside the power distribution cabinet, and avoid overheating and damage of electrical components.

[0025] In this embodiment, when the distribution cabinet is placed outdoors and it rains, rainwater falls on the waterproof cover 11 and slides down from the waterproof cover 11 to the ground, achieving a waterproof effect. When a strong wind blows, the wind carries a lot of dust, and the dust is blocked outside by the dustproof net 22 inside the distribution cabinet, achieving a good dustproof effect. When the air is very humid, it enters the cabinet body 3. When the humidity value inside the cabinet body 3 reaches a certain value, the controller receives a signal, and the dehumidifier 12 is powered on and starts working until the humidity value drops, and the dehumidifier 12 is powered off and stops working, achieving a good moisture-proof effect.
