As to the background art, the forced heat dissipation of the traditional box-type transformer substation only adopts a mode of adding filter cotton or a filter screen to the fan, and the mode is used for windless and clean environment with better effect, but the forced heat dissipation device is not functional in environments with large wind sand such as desert gobi and the like. When the air conditioner is used for a period of time in a severe environment, dust can block meshes and the air exhaust and heat dissipation functions are lost. And when the sand wind is very big, outside sand wind can blow into box-type substation inside, damages electrical components.

In order to improve the above-described problems, the present embodiment provides a box transformer substation protection cover that effectively prevents intrusion of external wind and sand or clogging of mesh holes, and is advantageous in terms of exhaust air heat dissipation.

Fig. 1 is a schematic structural diagram of a box transformer substation protection cover provided in the present embodiment, fig. 2 is a schematic structural diagram of a protection cover body 100 provided in the present embodiment, and referring to fig. 1 and 2, the box transformer substation protection cover provided in the present embodiment includes a protection cover body 100 and a filter 300. Wherein, the protection cover body 100 is provided with a first ventilation opening 111 and a second ventilation opening 131, the protection cover body 100 is arranged on the shell 710 of the box-type substation, the first ventilation opening 111 is communicated with the air outlet of the fan 730 of the box-type substation, and the filter 300 is arranged on the protection cover body 100 and shields the second ventilation opening 131.

Through the arrangement, the box transformer substation protective cover is externally arranged on the box-type substation, and can effectively prevent the environment under severe weather, for example, insect entering and external sand and wind invasion. And, the box transformer substation protection cover communicates the box transformer substation with the external environment through the first ventilation opening 111 and the second ventilation opening 131 so that internal heat flow of the box transformer substation is discharged, and when the box transformer substation, the box transformer substation protection cover can play a pressure relief function.

In order to further strengthen the resistance to the external environment, the second ventilation opening 131 is provided downward. In this way, wind and rain or wind and sand can be effectively prevented from entering the box-type substation, and the electric elements in the box-type substation are damaged.

In this embodiment, as shown in fig. 2, the protection cover body 100 further includes a first ventilation surface wall 110 and a second ventilation surface wall 130, and the first ventilation opening 111 is disposed on the first ventilation surface wall 110, and the second ventilation opening 131 is disposed on the second ventilation surface wall 130. Further, the second ventilation face wall 130 is disposed horizontally.

That is, the second ventilation opening wall 130 disposed horizontally is provided with the second ventilation opening 131 disposed downward, and the filter 300 is disposed on the second ventilation opening wall 130 and covers the second ventilation opening 131. Based on the above arrangement, the filter 300 prevents various insects and dust from entering, and at the same time, also prevents rain from entering, thereby ensuring safe and normal use of the box-type substation.

In addition, because the second air vent 131 is horizontally arranged, the dust deposit or the wind sand at the filter 300 falls down along with the gravity, and the filter 300 is kept clean, so that the filter 300 is blocked by dust or the wind sand, and the box transformer protective cover loses the functions of exhausting and radiating.

Further, the protective cover body 100 further includes a first wall 150, a second wall 170 and a third wall 190, which are sequentially connected at an included angle, and the second wall 170 is used for guiding the airflow and is disposed obliquely towards the first ventilation opening 111 and the second ventilation opening 131.

As shown in fig. 1, the second wall 170 is an air guiding wall inclined towards the first ventilation opening 111 and the second ventilation opening 131, and can guide air flowing inside the box transformer substation protection cover, that is, hot air exhausted by the fan 730 corresponding to the first ventilation opening 111 is guided to the second ventilation opening 131 and exhausted from the second ventilation opening 131.

In this embodiment, the unidirectional grille 500 is disposed at the first ventilation opening 111, and when the wind pressure of the blower 730 is greater than the external wind pressure, the unidirectional grille 500 is opened; when the external wind pressure is greater than the wind pressure of the blower 730, the unidirectional grille 500 is closed. Wherein, the unidirectional grille 500 is made of aluminum alloy. By the above arrangement, it is described that one side of the first ventilation opening 111 corresponds to the fan 730 of the box-type substation, and one side corresponds to the unidirectional grille 500. It should be further noted that the size and number of the unidirectional gratings 500 may be set according to actual needs.

On the one hand, when the blower 730 is not running, the unidirectional grille 500 will be closed under the action of gravity, the box-type substation is completely closed, and the box-type substation protective cover is isolated from the box-type substation, and further guarantee is provided for dust prevention and dust prevention.

On the other hand, when the blower 730 is opened at a high temperature in the box-type transformer substation for heat dissipation, when the air pressure of the blower 730 is greater than the external air pressure, the unidirectional grille 500 is opened under the blowing of the air flow of the blower 730, and at this time, the hot air generated by the blower 730 is smoothly discharged from the box-type transformer substation protective cover through the first ventilation opening 111 and the second ventilation opening 131; when the air pressure of the blower 730 is greater than the external air pressure, the unidirectional grille 500 will be closed under the wind force of the external strong wind, at this time, the box-type substation is closed, and the sand wind entrained by the strong wind cannot enter the inside of the box-type substation even though passing through the filter 300.

By the above arrangement, it is described that the case-change protective cover is provided with two layers of protective structures for coping with the external severe environment, wherein one layer of protective structure is a unidirectional grille 500 at the first ventilation opening 111, and the other layer of protective structure is a filter 300 at the second ventilation opening 131.

In detail, the filter 300 includes a filter screen, a first frame and a second frame, the first frame and the second frame are mounted in cooperation, and the filter screen is disposed between the first frame and the second frame.

In addition, the first ventilation opening 111 is provided with a one-way grille 500, the second ventilation opening 131 is provided with a filter 300, and the protective cover body 100 further includes a second surface wall 170 inclined toward the first ventilation opening 111 and the second ventilation opening 131.

Based on the above arrangement, when the blower 730 is not operating, the unidirectional grille 500 will be closed under the force of gravity and the box-type substation is completely closed. When the temperature in the box-type transformer substation is high and the fan 730 is started to radiate heat, when the air pressure of the fan 730 is larger than the external air pressure, the unidirectional grille 500 is opened under the blowing of the air flow of the fan 730, and at the moment, the hot air generated by the fan 730 is smoothly discharged from the box-type transformer substation protective cover through the first ventilation opening 111 and the second ventilation opening 131; when the air pressure of the blower 730 is greater than the external air pressure, the unidirectional grille 500 is closed under the action of the wind force of the external strong wind, and at this time, the filter 300 filters the wind sand to prevent the wind sand from entering the inside of the box-type substation protection cover; the unidirectional grille 500 isolates the box transformer substation protective cover from the box substation.

In summary, the present embodiment provides a box transformer substation protection cover, which includes a protection cover body 100 and a filter 300. Wherein, the shield body 100 is provided with a first vent 111 and a second vent 131.
