Abstract

The utility model provides a kind of low pressure vertical winding type coil, including stabilizer blade and conducting wire；Conducting wire is the flat strip with wide face and leptoprosopy, and conducting wire spiral is coiled and is layering using wide face as bottom surface；Column of the section of coil generally single turn coiling for ellipse.Every two conducting wires are one group of carry out coiling, and every group of two conducting wires each other close by wide face paste.The technical solution of the utility model, breach the multiturn coiling using conducting wire leptoprosopy the bottom of as in previous traditional technology, it uses and is curled up by bottom spiral single turn of wide face, not only increase the bearing area of coil, but also improve axial and radial anti-short circuit capability while saving material.Also, mechanical automation coiling may be used in the coil of the utility model, and product size is accurate, quality is more stable.

Description

A kind of low pressure vertical winding type coil

Technical field

The utility model is related to the low-voltage coils of transformer.

Background technology

Coil is the core for forming transformer circuit part.In whole process, coil plays electric energy and arrives electricity again to magnetic energy Transformation of energy acts on, while changes the size of voltage and current.According to electromagnetic principle it is found that the current-carrying being placed in magnetic field is led Body can generate electric power under the action of electric current and magnetic field.Although the electric power of normal condition lower coil is simultaneously little, once Transformer is impacted by short circuit current, and electric current becomes several times to tens times of normal rating electric current, and electric power is to rise to To hundreds times, this is just easy to that conducting wire is made to be caused conducting wire deformation so that conductor turns by tensile stress decades of times during normal operation Insulation is destroyed, final turn-to-turn short circuit coil burnout.

Existing coil is multicircuit winding, i.e. conducting wire is formed by bottom spiral multiturn coiling of leptoprosopy.Therefore, it is necessary to design one Kind of mechanical strength is more preferable and the coil of stable quality.

Utility model content

The purpose of the utility model is to overcome shortcoming in the prior art, it is good and can to provide a kind of anti-short circuit capability The high low pressure vertical winding type coil of automated production, Mass accuracy.

To achieve these goals, the technical solution adopted in the utility model is as follows：

A kind of low pressure vertical winding type coil, including stabilizer blade and conducting wire；Conducting wire is the flat strip with wide face and leptoprosopy, is led Line spiral is coiled and is layering using wide face as bottom surface；Column of the section of coil generally single turn coiling for ellipse； Bearing ring is additionally provided at the top and bottom of coil.

Further, the cross sectional shape of the shape of bearing ring and the coil matches.

Further, conducting wire is metallic copper, and outside is coated with insulated paint.

Further, the thickness of conducting wire is 1.12mm~5.6mm, wide 3.55mm~18mm.

The technical solution of the utility model breaches the multiturn coiling using conducting wire leptoprosopy the bottom of as in previous traditional technology, adopts It is curled up to wide face for bottom spiral single turn, the bearing area of coil is not only made to increase, but also improve axis while saving material To with radial anti-short circuit capability.Also, mechanical automation coiling, product size essence may be used in the coil of the utility model Standard, quality are more stable.

Description of the drawings

Fig. 1 is the structure diagram of the utility model.

Fig. 2 is the vertical view of the utility model.

Specific embodiment

The utility model will be further described below in conjunction with the accompanying drawings.

With reference to attached drawing.The utility model includes stabilizer blade 2 and conducting wire 1.Wherein, conducting wire 1 is with wide face 10 and leptoprosopy 11 Flat strip, thickness are 1.12mm~5.6mm, wide 3.55mm~18mm.

1 spiral of conducting wire is coiled and is layering with wide face 10 for bottom surface, so that the generally single turn coiling of coil 4 Section for ellipse column.The top and bottom of coil 4 are additionally provided with bearing ring 3, the shape of bearing ring 3 and cutting for coil 4 Face shape matches.In the present embodiment, each wire 1 individually turns to circle.It is of course also possible to every two conducting wires 1 for one group into Row coiling, the wide face 10 of the conducting wire of every group two are bonded each other.

Conducting wire 1 uses metallic copper, and outside is coated with insulated paint.

It should be pointed out that the embodiment be described above the utility model.However, the technical staff of art technology should manage Solution, the present utility model is not limited to the above embodiments, the principle for only illustrating the utility model described in above-described embodiment, There are many changes and improvements for the utility model also meeting under the premise of the scope of the utility model is not departed from, these changes and improvements are all It falls into claimed the scope of the utility model.
