DETAILED IMPLEMENTATION METHOD

[0026] In order to make the technical solutions and advantages of the present patent clearer, the present patent will be further described in detail below in conjunction with the accompanied figures.

[0027] As shown in FIG. 1, a ventilation and heat dissipation box-type substation, which includes a substation box 1 and a substation box roof 2 erected on top of the substation box 1. The surroundings of the substation box roof 2 located on the outside of the substation box 1 and not higher than the height of the top of the substation box 1. The substation box 1 is provided with a substation box door 3, and the substation box door 3 is provided with a return air inlet 31. The return air inlet 31 serves the function of making the gas outside the substation box 1 to flow into the substation box 1.

[0028] As shown in FIG. 2 and FIG. 3, the inside of the substation box roof 2 is provided with an inner top plate 21 that collects the heat in the substation box 1. A circulation fan 4 is arranged on the top of the inner top plate 21 and forms a circulation cavity 22 with the substation box roof 2. One end of the circulation cavity 22 away from the circulation fan 4 is connected with the outside of the substation box. When the density of heat in the air decreases due to thermal expansion and contraction, the hot air rises and is collected by the inner top plate 21, and when the circulation fan 4 is turned on, the air with a large amount of heat collected by the inner top plate 21 will enter the circulation cavity 22 and finally discharged to the outside of the substation box, so as to effectively avoid heat accumulation which affects the service life of electronic components.

[0029] It is necessary to mention that, the inner top plate 21 is inclined and the height of one end close to the circulation fan 4 is higher than that of the other end, so as the inclined inner top plate 21 serves the function of guiding heat to flow to the circulation fan 4, and improves the heat dissipation effect of the box-type substation. Meantime, the inner top plate 21 is connected with an inclined deflector plate 23, wherein the inclination angle between the inner top plate 21 and the horizontal plane is greater than 0° and smaller than 30°, and the inclination angle between the inclined deflector plate 23 and the horizontal plane is smaller than 60° and greater than the inclination angle between the inner top plate 21 and the horizontal plane. The inclined deflector plate 23 and the inner top plate 21 cooperate and serve the function of further guiding heat to flow to the circulation fan 4, and improves the heat dissipation effect of the box-type substation. It has to mention that, a refrigeration element is arranged in the circulation cavity 22. The refrigeration element plays a role of condensing the water vapor in the hot air, which is converted into liquid state water and adhered on the inner top plate 21 and inclined deflector plate 23, and discharged through the opening under the guidance of the inner top plate 21 and the inclined deflector plate 23, and the purpose of further dissipating the heat in the box-type substation is achieved.

[0030] As shown in FIG. 2 and FIG. 3, a downward opening is formed between the surrounding of the substation box roof 2 and the outer side wall of the substation box 1. And an air outlet plate 6 is arranged at the opening. Therefore, the setting up of a downward opening plays a role in preventing debris from entering the circulation cavity 22, and at the same time, it effectively prevents rainwater from entering and affecting the electrical safety of the box-type substation, and the air outlet plate 6 plays a further blocking role, preventing animals from entering the box-type substation through the opening and affecting the safety of the box-type substation. The top of the substation box 1 is provided with a plurality of box connectors 11. The lower side of the substation box roof 2 is provided with a plurality of box roof sleeves 24 matching the box connectors 11. The box roof sleeves 24 are provided with box roof connectors 5 which are elastic in nature. The box connectors 11 are inserted into the box roof sleeves 24 and abut the box roof connectors 5. When the box connectors 11 are inserted into the box roof sleeves 24, they play a role of connecting the substation box 1 and the substation box roof 2, and then under the action of the elastic box roof connectors 5, the ability of box-type substation to resist wind and vibration is improved, thereby significantly extending the service life of the box-type substation.

[0031] The above are only preferred embodiments of the present patent, and the protection scope of the present patent is not limited to the above embodiments, but all technical solutions under the idea of the present patent belong to the protection scope of the present patent. It should be pointed out that for those of ordinary skill in the art, several modifications and changes made without departing from the principles of the present patent should also be regarded as the protection scope of the present patent.
