Low-voltage large-current output transformer

Abstract

The invention discloses a low-voltage large-current output transformer, which comprises a primary side winding wound on an iron core and a secondary side winding wrapped outside the primary side winding. The secondary side winding is formed by assembling a first seat body, a second seat body and a second round-tube-shaped center post. A first center post and the second center post are large in superficial areas, capable of bearing large current and heat productivity, small in self loss and capable of producing large power. The second center post can be suitable for transformers with different secondary side windings, has generality and can achieve large-batch production. The secondary side winding is divided into three independent portions including the first seat body, the second seat body and the second center post, and is convenient to manufacture and assemble. Especially, the second seat body and the second center post are small in volume and can be made of scrap edges, thereby reducing the production cost. The second center post and the first center post adopt concentrically-nested installing structures, thereby facilitating expansion of the number of the secondary side windings of the transformer.

Description

technical field [0001] The invention relates to a transformer, in particular to a low-voltage, high-current output transformer suitable for electroplating, electrolysis and other industries. Background technique [0002] In electroplating, electrolysis and other industries, transformers are required to output low-voltage, high-current AC power. The secondary side of this transformer generally has only a few turns. The document discloses a transformer capable of outputting low voltage and high current. The technical scheme adopted by the transformer is as follows: it includes a primary winding wound on a ring iron core, and the secondary side is composed of a left base and a right base that are insulated from each other. , the left base and the right base are respectively provided with a left groove and a right groove with opposite opening directions, the left groove divides the left base into a left middle column and a left outer base, and the right groove divides the right ...

AI Technical Summary

Problems solved by technology

As we all know, due to the existence of the skin effect, when the alternating current passes through the conductor, the current will flow concentrated on the surface of the conductor. The surface area of ​​the left center column and the right center column of the above patent document is small, resulting in the output current of this kind of transformer smaller

[0004] 2. Since the secondary side of the transformer is often changed according to the needs, the secondary side of the above-mentioned transformer is connected by the left base body and the right base body, the left middle column and the left outer base body, the right middle column and the right outer base body, As a result, the left seat and the right seat are not universal
