The invention relates to an unequal sections iron core structure of saturated core superconducting current limiter. The iron core is a closed iron core and comprises an excitation section, a working section and a magnetic conduction section. The iron core is characterized in that: the cross-section area ratio of an excitation section iron core and a working section iron core is equal to between 1.01 and 10, the cross-section area ratio of the excitation section iron core and a magnetic conduction section iron core is equal to between 1 and 10, and cross-section area of the magnetic conduction section iron core is more than that of the working section iron core, and less than or equal to that of the excitation section iron core. The structure reduces the influence of magnetic leakage on the iron core by changing the structural shape and the dimension of the iron core further to cause magnetic potential on the iron core to be redistributed, can ensure that the iron core reaches the designed saturation under the
