Transformer structure

The invention discloses a transformer structure, which comprises a frame-shaped iron core, wherein a primary coil is wound on the left rim of the iron core; a secondary coil is wound on the right rim of the iron core; the iron core is a hollow iron core with a hollow cavity therein; the hollow cavity of the iron core is arranged into a ring along with the shape of the iron core; and the hollow cavity of the iron core is filled with a magnetic-conducting liquid. According to the transformer structure, the iron core is set to be the hollow iron core; and the hollow cavity of the iron core is filled with the magnetic-conducting liquid, so that magnetic coupling of the coils is achieved by cooperation of the magnetic-conducting liquid and the iron core. Compared with a transformer in the prior art, the iron loss can be effectively reduced; and the transformer structure has relatively long service lifetime. 本发明公开了种变压器结构，包括有呈框形的铁芯，所述铁芯左侧框边上缠绕有初级线圈，铁芯右侧框边上缠绕有次级线圈，所述铁芯为内有空腔的空心铁芯，铁芯中空腔随铁芯形状设为环形，且铁芯空腔中充入有导磁液。本发明将铁芯设为空心
