Background technique [0003] Transformers play a very critical role in the power transmission and conversion of power systems, so ensuring the stable operation of transformers is crucial to power systems. Short-circuit fault is one of the main faults in the operation of power grid system. When a short-circuit fault occurs in the power grid system, the cumulative deformation of transformer windings under the impact of short-circuit current is the main cause of transformer damage. Therefore, how to accurately analyze the cumulative deformation of transformer windings is the most effective way to prevent transformer dam...
