Abstract

The utility model discloses a kind of miniature transformers, including iron core, primary side winding and vice-side winding, and the iron core is annular in shape, and the vice-side winding and primary side winding are wound on iron core successively;It is provided with insulating layer between the vice-side winding and primary side winding, the insulating layer includes the adhesive tape being wound on vice-side winding and the insulating paper that is wound on adhesive tape;The input voltage of the primary side winding is 10KV, and the number of turns is 10000 circles, and the output voltage of the vice-side winding is 220V, and the number of turns is 220 circles.The utility model eliminates step-up transformer by could be adjusted to change the output voltage of transformer to vice-side winding the number of turns compared to for existing miniature transformer, simple in structure, the case where saving material, avoid wiring error.

Description

Miniature transformer
Technical field
The utility model is related to a kind of transformers, relate generally to a kind of miniature transformer.
Background technology
Transformer is the device for changing alternating voltage using the principle of electromagnetic induction, mainly by iron core (or magnetic core) and Coil forms, coil there are two or more than two windings, wherein the winding for connecing power supply is primary coil, remaining winding is secondary Grade coil, major function is voltage transformation, current transformation, impedance transformation, isolation, voltage stabilizing etc..
As shown in Figure 1, the existing miniature transformer for providing power supply to equipment is to export U with a voltage transformer 1ab= The AC power of 100V, this power supply are connected to the input terminal of step-up transformer 2, are raised to voltage from 100V by boost voltage device 2 The U needed1a1bEquipment is given to provide power supply after=220V, the shortcomings that this miniature transformer is:Complicated, waste material, company Link is easy error.
Utility model content
For the above the deficiencies in the prior art, the utility model proposes a kind of small-sized transformations simple in structure, saving material Device.
In order to achieve the above objectives, the technical solution of the utility model is:
A kind of miniature transformer, including iron core, primary side winding and vice-side winding, the iron core is annular in shape, it is described pair side around Group and primary side winding are wound on iron core successively;Insulating layer, the insulation are provided between the vice-side winding and primary side winding Layer includes the adhesive tape being wound on vice-side winding and the insulating paper being wound on adhesive tape;The input voltage of the primary side winding is 10KV, the number of turns are 10000 circles, and the output voltage of the vice-side winding is 220V, and the number of turns is 220 circles.
Preferably, the primary side winding and vice-side winding are formed using enameled wire coiling.
Preferably, the iron core using silicon steel sheet stack at.
Preferably, the thickness of the adhesive tape is 1-2mm, and the thickness of the insulating paper is 1-3mm.
The utility model to vice-side winding the number of turns by could be adjusted to change the output voltage of transformer, compared to existing small For type transformer, step-up transformer is eliminated, it is simple in structure, the case where saving material, avoid wiring error.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Attached drawing needed in description is briefly described, it should be apparent that, the accompanying drawings in the following description is only that this practicality is new Wherein two width of type for those of ordinary skill in the art without having to pay creative labor, can be with root Other attached drawings are obtained according to these attached drawings.
Fig. 1 is the circuit diagram of existing miniature transformer.
Fig. 2 is the circuit diagram of the utility model embodiment.
Fig. 3 is the winding structure figure of the utility model embodiment.
Specific implementation mode
Below in conjunction with attached drawing, the technical solution in the utility model is clearly and completely described, it is clear that retouched The embodiment stated is only the preferred embodiment of the utility model, instead of all the embodiments.Based in the utility model Embodiment, every other embodiment obtained by those of ordinary skill in the art without making creative efforts, all Belong to the range of the utility model protection.
Embodiment
As shown in Figures 2 and 3, the miniature transformer of the utility model includes iron core 3, primary side winding 4 and vice-side winding 5, iron Core 3 is annular in shape, using silicon steel sheet stack at;Primary side winding 4 and vice-side winding 5 are formed using enameled wire coiling, vice-side winding 5 and original Side winding 4 is wound on successively on iron core 3;Insulating layer is provided between vice-side winding 5 and primary side winding 4, insulating layer includes coiling Adhesive tape 7 on vice-side winding and the insulating paper 6 being wound on adhesive tape;The number of turns of primary side winding 4 is 10000 circles, input electricity Press UABThe number of turns of=10KV, vice-side winding 5 are 220 circles, the output voltage U of vice-side winding 5ab=220V.
The utility model to vice-side winding the number of turns by could be adjusted to change the output voltage of transformer, compared to existing small For type transformer, step-up transformer is eliminated, it is simple in structure, the case where saving material, avoid wiring error;Meanwhile by Insulating layer between primary side winding 4 and vice-side winding 5 includes two layers of adhesive tape and insulating paper, avoids to ensure that insulation in this way Effect extends the service life of transformer.
In the present embodiment, the thickness of adhesive tape 7 is 1-2mm, and the thickness of insulating paper 6 is 1-3mm.Due to the utility model There is two layers of insulation material, therefore two layers of insulation material can be thinner, is conducive to save between primary side winding 4 and vice-side winding 5 Material.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection domain within.
