Summary:The invention provides a preparation method of a current transformer, and belongs to the technical field of current transformers, and the preparation method comprises the following steps: preparing an iron core in advance; hardening and shaping the surface of the iron core to form a thin film layer for sealing and fixing the iron core on the surface of the iron core; spraying and curing ceramic powder on the surface of the thin film layer to form a protective film; winding the iron core with the thin film layer and the protective film to obtain a wound iron core; and the wound iron core is arranged in a shell, then vacuum pouring is carried out, the shell is filled with the iron core, and the current transformer is formed. The method has the beneficial effects that the surface of the prefabricated iron core is hardened and shaped, and then the ceramic powder is sprayed, so that the external force resistance of the iron core is improved, and the magnetic conductivity of the iron core of the finally prepared cu
