According to statistics, short circuit faults in transformer windings account for 70% to 80% of the total faults. Therefore, the study of the short circuit withstand capability of transformers holds significant importance. This paper focuses on investigating the winding deformation and short circuit strength of a ODFPS-700000/750 single-phase four-column transformer during high-medium voltage operation and low-voltage side short circuit conditions. The influence of pads and struts offset on various aspects of windings is considered during the implementation. The paper presents the distributions of magnetic leakage field, current, winding deformation displacement, and electromagnetic forces under transformer short circuit conditions. This provides a novel approach for the verification of short circuit strength in large-scale transformer windings.
