Description

Low-voltage coil for transformator
Technical field
The present invention relates to a kind of low-voltage coil for transformator.
Background technology
Dry-type transformer, for oil-filled transformer, is that a kind of iron core is not immersed in iknsulating liquid with low-voltage coil Transformator, be generally used for local lighting, electronic circuit.Along with transformator requirement is improved constantly by transformator user, become The structure of depressor becomes increasingly complex, and in order to meet the demand of voltage, the low-voltage coil quantity on transformer core gets more and more, and becomes This is higher.
Continuous progressive along with transformer technology, adequately and reasonably utilize low-voltage coil inner space to become most to pay close attention to asks Inscribing, this and cost have direct relation coil to be often referred to wire winding ringwise, and the application of modal coil has: horse Reach, inductance, transformator and loop aerial etc..As the one of coil, low-voltage coil is widely used in transformator.Along with transformation Being continually changing of device working environment, especially under complex environmental condition, to the low-voltage coil of its inside in insulating properties Requirement on energy is more and more higher.
Summary of the invention
The present invention provide a kind of have ensure that good electrically and mechanically intensity, can be greatly saved into material-saving again The low-voltage coil for transformator of this advantage.
The technical scheme is that a kind of low-voltage coil for transformator, the described low-voltage coil for transformator Including coil base and the multicircuit winding that is wound in coil base, described multicircuit winding is by metal material layer and insulating barrier Coiling is formed, and described low-voltage coil also includes that some air gap stays, described air gap stay are positioned at described multicircuit winding mid portion Metal material layer and insulating barrier between, and through metal material layer and the axial distance of insulating barrier, outside described multicircuit winding Surface is provided with several air drains.
In a preferred embodiment of the present invention, described air gap stay is strip, and cross section is rectangle.
In a preferred embodiment of the present invention, the cross section of described low-voltage coil is rounded.
In a preferred embodiment of the present invention, described metal material layer is iron sheet.
In a preferred embodiment of the present invention, the number of described air gap stay is 40.
In a preferred embodiment of the present invention, the number of described air drain is 7.
A kind of low-voltage coil for transformator of the present invention, has and ensure that good electrically and mechanically intensity, again may be used With material-saving, the advantage being greatly saved cost.
Accompanying drawing explanation
Accompanying drawing 1 is used for the sectional view of the low-voltage coil of transformator for the present invention;
Accompanying drawing 2 is used for the structural representation of low-voltage coil one preferred embodiment of transformator for the present invention;
In accompanying drawing, the labelling of each parts is as follows: 1, coil base, and 2, multicircuit winding, 3, air gap stay.
Detailed description of the invention
Preferred embodiment to invention is described in detail, so that advantages and features of the invention can be more below in conjunction with the accompanying drawings It is prone to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
Wherein, the described low-voltage coil for transformator includes coil base 1 and the multiturn being wound in coil base Winding 2, described multicircuit winding 2 is to be formed by metal material layer and insulating barrier coiling, and described low-voltage coil also includes some air gaps Stay 3, described air gap stay 3 between metal material layer and the insulating barrier of described multicircuit winding 2 mid portion, and through Metal material layer and the axial distance of insulating barrier, described multicircuit winding 2 outer surface is provided with several air drains, described air gap stay 3 In strip, cross section is rectangle, and the cross section of described low-voltage coil is rounded, and described metal material layer is iron sheet, described air gap The number of stay is 40, and the number of described air drain is 7.
After low-voltage coil structure coiling completes, only needing drying, end seal, it is not necessary to cast, concrete technology flow process is: Low-voltage coil is coiling on common die, is directly extracted by low-voltage coil, then proceed to next low-voltage coil of coiling after complete, The seriality produced is ensured.Because the layer insulation of low-voltage coil, overhang insulation and external insulation use from resin Insulant, thus coil complete for coiling is placed directly in curing oven is heated after take out the most plastic, and insulating properties, machinery Performance is ensured.
The performance indications of low-voltage coil are exactly mainly the size of inductance value.It addition, the wire of coiling low-voltage coil typically comes Saying always have certain resistance, generally this resistance is the least, can ignore and not remember.But when the electricity flow through in some circuit When flowing the biggest, this least resistance of coil cannot have ignored because the biggest electric current can on this coil consumed work Rate, causes coil heating even to burn out, so it is also contemplated that the electrical power that coil can bear sometimes.Inductance value L represents line Enclose inherently characteristic, unrelated with size of current.In addition to special low-voltage coil (colour coding inductance), inductance value is marked the most specially Note is on coil, and marks with specific title.Inductance value is also referred to as electrodynamic capacity, represents that inducer is produced from sensing capability One physical quantity.The size of inductor current amount, depend primarily on the number of turns (number of turn) of coil, winding method, with or without magnetic core and Material of magnetic core etc..Generally, wire circle is the most, the coil of coiling is the most intensive, and inductance value is the biggest.There is the coil ratio of magnetic core Winding inductance quantity without magnetic core is big;The coil that magnetic core permeability is the biggest, inductance value is the biggest.The present invention provides a kind of for transformation The low-voltage coil of device, has and ensure that good electrically and mechanically intensity, again can be with material-saving, the advantage being greatly saved cost.
The detailed description of the invention of the present invention, but protection scope of the present invention is not limited thereto, any is familiar with this area Technical staff in the technical scope that disclosed herein, the change can expected without creative work or replacement, all should contain Cover within protection scope of the present invention.Therefore, the protection model that protection scope of the present invention should be limited with claims Enclose and be as the criterion.
