Abstract
A self-clamping structure for solving a short-circuit resistance problem of amorphous alloy transformers comprises an A-phase coil, a B-phase coil and a C-phase coil which are horizontally arranged, the A-phase coil being in close contact with the B-phase coil, and the B-phase coil being in close contact with the C-phase coil. By using a solidified low-voltage coil as a fastening splint and binding with a high-strength binding strap, the low-voltage coils of the A-phase and the B-phase clamp and fix a weak portion between the A and B phases; and the low-voltage coil of the B-phase and the C-phase clamp and fix a weak portion between the B and C phases. Outer sides of the A- and C-phase coils are each provided with a high-strength insulation splint, so that the splint and the low-voltage coil of corresponding phase constitute the splint pair to clamp and fix the corresponding weak portion.
