The utility model discloses a double -deck double -transformer box -type substation, including box, top cover and baffle, the box is divided into high -low voltage layer and transformer layer by baffle, and transformer layer is located high -low voltage layer top, and top cover is located transformer layer top. Transformer layer includes first, second transformer room, and high -low voltage layer includes adjacent high -voltage cable isolation chamber, high -voltage chamber and low -voltage chamber, and the first ventilation groove is equipped with between transformer layer and high -low voltage layer, and top cover is equipped with ventilation structure, and the first ventilation groove and ventilation structure form the heat dissipation channel of transformer layer, and the second ventilation groove and exhaust structure that high -low voltage layer outside set form the heat dissipation channel of high -low voltage layer. The utility model two transformer rooms can assemble two transformers on the upper layer structure, and the lower layer is high -low voltage cabinet, compared with the conventional single -deck or double -deck box -type substation, and the upper and lower layers adopt independent heat dissipation and do not interfere with each other, can effectively avoid the lower layer equipment heating too big influence upper layer transformer operating condition.
