Method for enlarging diameter varying range of adjustable winding mould of transformer coil

Abstract

The invention relates to a method for enlarging a diameter varying range of an adjustable winding mould of a transformer coil. The method for enlarging the diameter varying range of the adjustable winding mould of the transformer coil includes following steps: preparing a plurality of wood struts; confirming the size and the distance of threaded holes of the wood struts and intervals and the length of struts of an existing mould according to the distance of bolt holes, and the width and the length of bracing plates of the existing mold; drilling stepped holes in positions of the wood struts, corresponding to the bolt holes in the existing mold; replacing screws used to install the bracing plates on the existing mold with lengthened screws so as to install the wood struts on the outer sides of the existing mold bracing plates, and thereby achieving the purpose of enlarging the diameter varying range of the adjustable winding mould. The method for enlarging the diameter varying range of the adjustable winding mould of the transformer coil enlarges the diameter varying size of the adjustable winding mould, not only meets demands of coil winding, but also simultaneously saves cost used by purchasing another coil mold, shortens a production period of a product, does not damage the existing mould, facilitates installation and dismantlement, and is strong in practicability and remarkable in economical benefit.

Description

technical field [0001] The invention relates to a transformer manufacturing technology, in particular to a method for enlarging the variable diameter range of a transformer coil with an adjustable winding die. Background technique [0002] At present, in the field of transformer manufacturing, adjustable winding dies are mainly used for coil winding. Now, the transformer industry is developing rapidly, and user units have higher and higher requirements for the performance of transformer products. Therefore, enterprises continue to develop innovative high-voltage, high-current large-capacity transformers, and these transformers are major products in national key projects. Therefore, the production schedule of the product is not only urgent, but also the product structure is complex. The requirements for tooling tools used in production are also getting higher and higher. The mold used for conventional products generally only needs to be 3 meters, but these high-voltage, la...
