Abstract:
The finite element check model of the radial short-circuit withstand ability of amorphous alloy transformer rectangular winding is built based on the bifurcation instability theory. The buckling analytical method is employed to calculate the buckling critical loads and buckling modes under different compression forces of rectangular winding. The short-circuit withstand capability of several amorphous alloy transformer windings are checked, and the validity of the proposed computational model is proved. At the same time, the influence factors of radial short-circuit withstand ability of rectangular winding are studied. The results show that the maximal spacing of the spacers is the most important factor to prevent the winding from local buckling. A state of complete failure of many inner winding spacers is one of the reasons leading to the shortage of the radial withstand short-circuit ability of amorphous alloy transformer. The transformer radial limit load is approximately proportional to the cube of the thickness of the wire, so the short-circuit withstand ability of rectangular winding can be effectively improved by increasing the radial thickness of the wire.
