Semi-buried dry-type transformer

The invention relates to the field of transformers, in particular to a semi-buried dry-type transformer which comprises a dry-type transformer body, a protection box, a circulating pipe and a cooling assembly. A placement plate in the protection box divides an inner cavity of the protection box into a mounting cavity and a cooling cavity, an inner cavity of the circulating pipe is communicated with the mounting cavity, a horizontal section of the circulating pipe is arranged in cooling water in the cooling cavity, and an exhaust fan is arranged at one end of the circulating pipe. By adopting the technical scheme, the protection box, the circulating pipe and the exhaust fan form a closed circulating cooling passage, so that the air in the protection box exchanges heat with the cooling water in the cooling cavity at the horizontal section of the circulating pipe, the temperature of the air in the circulating pipe is reduced, and the heat dissipation of the dry-type transformer is further realized; the dry-type
