Method for binding iron core of transformer

Abstract

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.

Description

[0001] Technical field: [0002] The invention relates to a transformer iron core binding method, which belongs to the technical field of transformer manufacturing technology. Background technique: [0003] At present, in the production of transformers, a single material is generally used for manual or mechanical binding of the transformer core, which only achieves the purpose of binding the iron core, and has no shielding effect on the iron core. , increasing the manufacturing cost. Invention content: [0004] The object of the present invention is to provide a transformer core binding method. The binding strap has dual functions of core binding and core shielding, which shortens the binding time, reduces the manufacturing cost of the transformer, and solves the above-mentioned problems in the background technology. [0005] The technical solution of the present invention is: a transformer core binding method. The iron core is bound by a binding machine. The inner layer ...
