The utility model discloses a current transformer convenient to assemble and disassemble, and belongs to the technical field of current transformers. The technical problem to be solved is to provide acurrent transformer convenient to assemble and disassemble. According to the technical scheme for solving the technical problem, the transformer coil comprises a coil shell, bottom feet are arrangedat the fixed end of the coil shell, the bottom feet and the coil shell are integrally formed, and the bottom feet are fixedly connected with a fixing plate through bolts; the fixing plate is insertedinto a clamping groove formed in the mutual inductor base to be fixed. The mutual inductor base is specifically a stainless steel plate with a certain thickness; a pair of self-control screw holes areformed in the two ends of the mutual inductor base, a pair of clamping grooves are further formed in the inner sides of the self-control screw holes, and the thickness of the clamping grooves is matched with the thickness of the fixing plate. The utility model is applied to the current transformer.
