[0025] Embodiment: An anti-condensation structure suitable for a 10kV switch of an outdoor common box type electric box body, such as Figure 1-Figure 4As shown, it includes a common box type electric box body 1, the front side of the common box type electric box body 1 is provided with a main door panel 2 and auxiliary door panels 3 located on both sides of the main door panel 2, the main door panel 2 and the auxiliary door panel 3 are provided with a heat dissipation net 4 connected to the inside of the common box type electric box body 1, and it is characterized in that: the backs of the main door panel 2 and the auxiliary door panel 3 are provided with a limit frame 6 surrounding the corresponding sides and bottom of the heat dissipation net 4, the limit frame 6 is a U-shaped structure, and the interior of the limit frame 6 is provided with a detachable anti-condensation component, the anti-condensation component seals the internal opening of the corresponding heat dissipation net 4 and is connected to the upper and lower parts, and the inner bottom surface of each limit frame 6 is provided with a dust exhaust hole 5 connected to the outside of the common box type electric box body 1, the anti-condensation component includes an insulating frame 7 sliding inside the limit frame 6, and the interior of the insulating frame 7 is inlaid with a drying net 701 corresponding to the heat dissipation net 4.
[0026] The two ends of the limit frame 6 are symmetrically provided with slide grooves 601, and the two ends of the insulating frame 7 are symmetrically connected with sliders 702 that slide in the slide grooves 601. By symmetrically providing the slide grooves 601 in the limit frame 6, the anti-condensation component arranged in the limit frame 6 can be docked and limited, so as to prevent the anti-condensation component from falling off from the limit frame 6 due to external collision.
[0027] The sliders 702 on both sides of each of the insulating frames 7 are provided with connecting holes 704 and connecting blocks 703 in the upper and lower pairs. The upper and lower insulating frames 7 are stacked and docked by connecting the corresponding connecting blocks 703 to the connecting holes 704. By providing the connecting blocks 703 and the connecting holes 704 on the two sliders 702 of the insulating frame 7, it is convenient to splice and install multiple groups of insulating frames 7 inside the limiting frame 6, and they can also be adjusted and installed according to the lengths of different heat dissipation nets 4.
[0028] A power controller 8 connected to the anti-condensation component is arranged on the outer side of each of the limit frames 6. The power controller 8 is electrically connected to the insulating frame 7 through a wire. By arranging the power controller 8 connected to the anti-condensation component on the limit frame 6, the power controller 8 can heat the anti-condensation component through the wire to prevent humid air from condensing through the anti-condensation component to produce water droplets, thereby drying the humid air.
[0029] A baffle 602 is vertically arranged on the rear side of each of the limit frames 6. By arranging the baffle 602 inside the limit frame 6, when the bottom of the anti-condensation component located in the limit frame 6 is inserted into the interior of the limit frame 6, the bottom of the anti-condensation component is located in the area between the baffle 602 and the interior of the limit frame 6, which has the effect of bottom support for the anti-condensation component installed inside the limit frame 6, and can also guide the dust falling on the anti-condensation component downward to the internal bottom surface of the limit frame 6, and then discharge it outward from the dust exhaust hole 5.
[0030] Working principle of the utility model: by arranging anti-condensation components and limit frames 6 corresponding to the heat dissipation net 4 on the back of each main door panel 2 and the auxiliary door panel 3, the humid air entering the common box type electric box body 1 from the outside can be dried to avoid the harm of short circuit caused by the penetration of humid air into the common box type electric box body 1. At the same time, the anti-condensation device in the technical solution is assembled in the way of upper and lower splicing, and can be adapted and adjusted according to the length or height of different heat dissipation nets 4, which is convenient to use;
[0031] At the same time, the anti-condensation components that are stacked and docked up and down cooperate with the limit frame 6 and the dust discharge hole 5 connected to the outside at the bottom of the limit frame 6, which can not only perform multiple limit installations on the anti-condensation components to improve the stability after assembly, but also some water droplet solutions generated in the dry humid air will drip downward on the inner bottom surface of the limit frame 6, and then be discharged outward from the channel of the dust discharge hole 5, which has the advantage of directional guidance and outward discharge of water droplets condensed by the humid air on the anti-condensation components.
[0032] The device adopts a detachable anti-condensation component, which can be easily maintained and replaced. At the same time, it is assembled by splicing up and down, and can be adapted and adjusted according to different heat dissipation net lengths or heights, which improves the flexibility of use. In addition, the power controller 8 is electrically connected to the insulating frame 7 through a wire, and is heated in the anti-condensation component to prevent humid air from condensing through the anti-condensation component to produce water droplets, thereby drying the humid air. Therefore, in outdoor environments, the device has good moisture-proof and anti-smog effects, and can effectively ensure the safe use of the 10kV switch of the common box type electrical box body.
