Compensation type transformer iron core

The utility model relates to the technical field of transformer iron cores, in particular to a compensation type transformer iron core. A compensation type transformer iron core comprises a core body formed by stacking silicon steel sheets, and further comprises brackets which are symmetrically arranged at the upper end and the lower end of the outer side of the core body, detachably connected with the core body and used for clamping and fixing the core body. The elastic components are symmetrically arranged at two ends between the brackets and are used for elastically connecting the core body; the binding and fixing assemblies are uniformly and symmetrically arranged between the brackets and are used for positioning and limiting the core body; according to the iron core, the elastic assembly and the binding and fixing assembly are designed, so that the elastic assembly can play a role in expanding and buffering when the core body is heated and expanded, and position deviation between the core body and the br
