the box-type transformer is used as a whole set of distribution equipment and is formed by organically combining a transformer, high-voltage control equipment and low-voltage control equipment. The basic principle of the transformer is that reasonable assembly is carried out according to a specified sequence through a pressure starting system, an armored wire, a transformer substation full-automatic system, a direct current point and corresponding technical equipment, and all components are installed in a specific waterproof, dustproof and rat-proof completely-sealed toughened box body structure, so that the specific transformer is formed. Box-type transformers have been widely used in power engineering construction.

because of the large size of the dry-type and oil-immersed transformer cores, the prior art in China generally adopts a manual-matching manual lamination mode to produce the dry-type and oil-immersed transformer cores, however, the following problems generally exist in the process:

1. when the iron core sheets of the dry-type and oil-immersed transformers are manually laminated, because the automation degree is low, only the iron core sheets with the same size on one iron core column can be stacked at one time, and the iron core sheets of the dry-type and oil-immersed transformers are generally formed by splicing five iron core columns of three different types, so that the efficiency of manually matching and manually laminating the iron core sheets of the transformers is low;

2. because of the dry-type behind the lamination, oil-immersed transformer core forms for cylindrical structure concatenation, so dry-type, oil-immersed transformer core's iron core piece is not unidimensional, consequently just need the iron core piece of a large amount of not unidimensional to place at lamination production site, thereby the required area on lamination production site has been increased, and need go to the position of different iron core pieces of placing when manually taking the iron core piece of not unidimensional, thereby make dry-type, oil-immersed transformer core lamination production process is comparatively mixed and disorderly, thereby lead to the in-process of taking the iron core piece to cause the damage to the iron core piece easily, and the efficiency of taking the iron core piece of not unidimensional is also comparatively low.
