Disassembly and transportation method for high-impedance transformer

The invention relates to a high-impedance transformer disassembly and transportation method, which comprises the following steps: step 1, disassembly: four square variable cross-section iron cores, namely a first disassembly iron core module, a second disassembly iron core module, a third disassembly iron core module and a fourth disassembly iron core module, a coil assembly body, a modular lead, a series reactor body, an upper oil tank and a lower oil tank are obtained, and the four square variable cross-section iron cores are respectively a first disassembly iron core module, a second disassembly iron core module, a third disassembly iron core module and a fourth disassembly iron core module; the second and third iron core disassembling modules are the same in structure and are formed by combining two semicircular cross-section core columns with opposite openings, and the first and fourth iron core disassembling modules are of mirror image structures and are formed by combining elliptical cross-section side
