The invention relates to a method for binding an iron core of a
transformer, which belongs to the technical field of
transformer manufacturing processes. The method adopts a technical scheme that: the iron core is bound by a binding
machine; an inner binding band of the iron core is a
semiconductor electric band (6), and an outer binding band is a special weftless band (3) for iron core binding; packing wood (4) is arranged on the end part of the an exposed head of a coil, and
semiconductor electric vanish (7) is coated on the packing wood for shielding the iron core; the
semiconductor electric
varnish is reliably connected with the semiconductor electric band; and the binding is carried out in a way of combining the iron core binding and the iron core shielding together. When the method is used, the iron core is bounded by the binding
machine, the inner binding band of the iron core is the semiconductor electric band, and the outer binding band is the special weftless band for the iron core binding. In the invention, the iron core is bound by the binding
machine, the inner binding band of the iron core is the semiconductor electric band, and the outer binding band the special weftless band for the iron core binding. The technology combines the regular iron core binding and an iron core shielding
barrel together, and the binding bands have the double function of iron core binding and iron core shielding, so that
binding time is shortened and the manufacturing cost of the
transformer can be reduced; and using effects are good, binding requirements are met, the iron core is well shielded, and requirements on product quality are met.
