Power transformer capable of automatically adjusting oil level

The invention discloses a power transformer capable of automatically adjusting an oil level. The power transformer comprises a box body and an iron core which is positioned in the box body, wherein a radiating plate is arranged on the circumferential side of the box body through an elastic mechanism; an annular sleeve is arranged on the circumferential side of the box body; a flow-guiding part is arranged below the annular sleeve; a radiation-preventing thermal-insulation coating layer is arranged outside the flow-guiding part; a conduction pipe which is connected with the flow-guiding part is arranged below the flow-guiding part; a hole is formed in the ground below the box body; and the conduction pipe is positioned in the hole. The transformer does not need a radiating fan; and meanwhile, the transformer is good in the cooling effect, and safe and reliable in operation. 本发明公开了种油位自调节电力变压器，包括箱体和位于箱体内铁芯，所述箱体周侧通过弹性机构设有散热板，所述箱体周侧设有环形套筒，所述环形套筒下设有导流件，所述导流件外侧设置抗辐射隔热涂料层。所述导流件下设有与之连通的导管。箱体下的地面设有地洞，所述导管位于地洞内。该变压器无需安装
