Abstract: In order to verify the engineering availability of a transformer anti-short-circuit calculation method, based on the finite element method, transformer theory and national standard recommended values, the winding modeling analysis software was applied to establish the transformer winding model, and the finite element method was used to analyze the short-circuit force of the transformer winding and check the strength.Finally, taking a transformer that has passed the sudden short-circuit test as an example, the engineering application effectiveness of the anti-short-circuit calculation method was verified.
