Abstract

The utility model discloses an improved structure of a transformer, which mainly comprises a primary-side coil, secondary-side coils and an iron core. The primary-side coil comprises an outer frame; two openings are formed in the middle of the outer frame; primary-side coil windings are arranged inside the outer frame in the positions of the openings; conducting wires at two ends of each primary-side coil winding protrude out of the outer frame; two secondary-side coils are connected beside the primary-side coil; each secondary-side coil comprises a frame; a secondary-side coil winding is arranged at the outer part of the frame; an opening is formed in the middle of the frame; and the opening is communicated with the two openings of the primary-side coil. The iron core is arranged in the openings of the primary-side coil and the secondary-side coils in a penetrating manner to enable the primary-side coil, the secondary-side coils and the iron core to be combined as an integral transformer structure. The utility model ensures that the manufacturing cost of the transformer is reduced, and only homogeneous primary-side coil winding or secondary lateral coil winding products are required to be produced. Therefore, the production yield is improved, the maintenance is easier, and the service life of the product is relatively long.

Description

The structure-improved of transformer

Technical field

The utility model is the structure-improved about a kind of transformer.

Background technology

The coil form transformer is one of modal project in the existing power transformer product, and it uses history to surpass more than the century.Also because use for a long time and demand, so the coil form transformer has many improvement so far, in the hope of better application.Yet, no matter developing and which kind of form, it is consistent that the principle of this coil form transformer remains.

Aforementioned coil form transformer is a principle of utilizing electric energy and magnetic energy transformation induction, with two groups of coil windings on the housing of ccontaining common iron core (core).These two groups of coils generally are divided into the first siding ring that connects power end, and the second siding ring that connects load end.When first siding ring connects AC power, the electric current that passes through in this coil can produce magnetic flux change in iron core, and the second siding ring of the other end can produce the alternating current of another same frequency because of induction.And the relation of induced voltage is the coil turn ratio that depends on two groups of coils.If the second siding ring number of turn is greater than first siding ring, then output voltage can become step-up transformer greater than input voltage; Otherwise less than first siding ring, then output voltage can become step-down transformer less than input voltage as if the second siding ring number of turn.

Therefore, the function of existing coil form transformer depends primarily on the setting of coil.The material, thickness, the number of turn ratio that comprise coil ... or the like, all be the key factor that influences this transformer function or the good and the bad.

Yet the mode of finishing of existing coil form transformer is still iron core and framework assembled and winds the line after finishing.The shortcoming of this kind method has down:

1. production line complexity, it must design a series of processing procedure and finish a transformer, if wherein a link generation problem is arranged, for example winds the line the stage, and the transformer that promptly may cause producing damages, and causes huge loss.And complicated production line is difficult for overhauling, so the probability that has problems is also higher.

2. quality easy care not, its first siding ring and second siding ring can't be tested separately, thus be difficult to control of quality in process of production, as long as and an end generation problem is arranged, promptly cause damage of product, its product yield is reduced.

3. cost is higher, because all trades and professions are for the demand difference of transformer, and each transformer all must the independent processing procedure of design, can't change easily, and nature can't force down cost.

The utility model content

Main purpose of the present utility model is to provide a kind of structure-improved of transformer, and it has and disposes effect flexibly, and the user looks the power of required transformer, the unit of selecting to be suitable for makes up, can finish required transformer device structure, significantly reduce cost, and reduce generation of waste.

Another purpose of the present utility model is to provide a kind of structure-improved of transformer, and it only need be provided with a spot of production line, again according to the power demand combined transformer, makes the production of factory more efficient, avoids the space waste with idle.

A purpose more of the present utility model is to provide a kind of structure-improved of transformer, and its product has the yield of height because the problem of avoiding primary side coiling institute to be produced, so be difficult for breaking down, and safeguard easy, the raising life of product.

Another purpose of the present utility model is to provide a kind of structure-improved of transformer, and thick, thin end can not take place the coiling of its secondary side twines mutually, thus avoid short circuit problem between genetic horizon, keep the normal use of transformer.

Can reach the structure-improved of the transformer of above-mentioned utility model purpose, mainly be that first siding ring, second siding ring and the iron core of this transformer are separately made, and the demand of looking makes up again, so quality management is more or less freely, significantly reduces cost.The first siding ring of this transformer includes housing, is formed with two openings in the middle of this housing, is provided with the primary side coiling in the housing of this opening part, and the two ends lead of this primary side coiling is protruded out in the housing outside.This second siding ring rests on the second siding ring next door side by side with two, and this second siding ring includes framework, and this framework outside is arranged with the secondary side coiling, and has opening in the middle of this framework, and two openings of this opening and first siding ring connect.This iron core then is set in the opening of this first siding ring and second siding ring, makes this first siding ring, second siding ring and iron core group synthesize a complete transformer device structure.

The utility model and prior art are compared, and have more following advantage:

1. the utility model can reduce the production cost of transformer, and factory only need produce coiling of monistic primary side or secondary side coiling product, looks required transformer efficiency again and makes up and get final product, and not only ties the cost-saving, and can reduce generation of waste.

2. the utility model can increase the space utilization of production line, and factory need not to be provided with a large amount of production lines, and the flow process of each production line is comparatively simple, not only makes production more efficient, and avoids the space waste with idle.

3. the utility model can improve the quality of power transformer product, but the primary side of each transformer winds the line and all individual inspiration of secondary side coiling, improve and produce yield, and maintenance is also more or less freely, and life of product is longer.
