The invention discloses a box-type substation and relates to the field of power transformation operation and maintenance. The box-type substation comprises a box body, a plurality of partition plates, a water tank and a heat pump system, wherein the interior of the box body is divided into a plurality of chambers through the partition plates; the heat pump system comprises a compressor, a first heat exchanging structure, an expansion valve and a second heat exchanging structure. The first heat exchanging structure is used for heating water in the water tank. Heat exchanging channels are arranged in the partition plates and a top plate of the box body. The second heat exchanging structure comprises a first heat exchanging path and a second heat exchanging path. A first circulation loop for a first heat exchanging medium is formed by the first heat exchanging path and the heat exchanging channel. A second circulation loop for a second heat exchanging medium is formed by the second heat exchanging path, the compressor, the first heat exchanging structure and the expansion valve. According to the box-type substation, very good heat dissipation can be formed, heat is applied to heating water in the water tank, waste heat is effectively utilized, and energy conservation and environment protection are achieved.
