Box transformer substation protective cover

The embodiment of the utility model provides a box transformer substation protective cover, and relates to the field of box transformer substation heat dissipation. The box transformer substation protective cover comprises a protective cover body and a filtering piece. The protective cover body is provided with a first ventilation opening and a second ventilation opening. The first ventilation opening is communicated with an air outlet of a fan of the box-type substation, so that internal heat flow of the box-type substation can be discharged conveniently, and when the box-type substation is in the box-type substation, the box-type substation protective cover can play a role in pressure relief. In addition, the filtering piece is arranged on the protective cover body and shields the second ventilation opening, so that the environment in atrocious weather is effectively prevented, for example, insects are prevented from entering the protective cover and external sand wind is prevented from invading the protect
