چکیده انگلیسی
International Thermonuclear Experimental Reactor (ITER) adopts a pulsed power electric network (PPEN) to feed the pulsed loads including the superconducting coils and the heating and current drive (H&CD) systems, and the PPEN is received from 400Â kV grid and transformed to 66Â kV and 22Â kV distribution voltage levels via 3 main step-down transformers. The short-circuit currents of PPEN transformer are calculated based on theoretical formulas. Then the short-circuit leakage magnetic field is simulated via a two-dimensional finite element analysis software. Finally, the short-circuit electrodynamic forces and temperature rises on windings are calculated and the results are compare with the allowable values in IEC 60076-5. All calculated values of short-circuit electrodynamic forces and temperature rises are within allowable values limits. It is proved that PPEN transformer has enough anti-short circuit strength on windings.
