Abstract
The utility model relates to an annular inductor with an open air gap, which is composed of an annular magnetic ring and a coil which is wound on the magnetic ring. The utility model is characterized in that the plane of the annular magnetic ring is provided with an air gap, the inner of which is large and the external of which is small, in the vertical direction. The utility model has the advantages of uniform temperature rise of inner and outer rings, fire resistance, small energy consumption, long service life, etc. Therefore, the utility model can be widely used for lighting electrical appliances and industrial electrical appliances.
Description
The utility model relates to ring-type inductor in the industrial electrical equipment field.
At present, the inductor of opening air gap comprises annular, oval ring, square annular, its air gap of opening of polygon annular all are equidistant parallel air gaps, with the function of implementing to shake and flow, but the inductor that often has this air gap burns because of heating, see its phenomenon and be the long outer ring temperature rise of the short inner ring temperature rise ratio girth of girth and burn, tracing it to its cause, to be that parallel air gap is unreasonable cause.
The purpose of this utility model provides a kind of winding coil Internal and external cycle temperature rise one, cause save the inductance energy consumption open the air gap toroidal inductor.
The technical scheme that realizes the utility model purpose is: open air gap ring-type inductor by the ring-shaped magnetic circle and forms around top coil, it is characterized in that: little air gap outside having in greatly on the vertical direction of ring-shaped magnetic circle plane.
By the magnetic circuit principle as can be known, air-gap separation 1 equates so magnetic potential all is Hd in the parallel air gap
0=0.8 φ * l
0/ S
0So the magnetic potential in the arbitrary ring layer face from the inner ring to the outer ring is all identical, i.e. H
1* L
1=H
2* L
2..., thereby magnetic strength H
1With H
2With the long L of inner ring
1With the long L in outer ring
2Linear inverse ratio, outer ring L
2Long then magnetic field intensity H
2Just, inner ring L
1Short then magnetic field intensity H
1Just strong, magnetic flux density is just big, so the caloric value of inner ring is just big than the outer ring, temperature rise is easily burnt coil covering and caused damaging whole inductance under the high temperature.Air-gap separation l of the present utility model
1＞l
2Big outer little tubaeform in being, so magnetic potential landing Hd
1Greater than outer ring magnetic potential landing Hd
2, because Internal and external cycle aspect and magnetic potential of air gap summation are definite value, this has just reduced the magnetic potential in the inner ring aspect, if make l
1/ l
2=L
2/ L
1, then the potential drop in the Internal and external cycle aspect is tending towards evenly, and caloric value must balanced be controlled, and makes winding coil temperature rise unanimity, because the temperature rise unanimity, inductor is difficult for burning, and has prolonged the useful life of inductor, and the inductor energy consumption is reduced.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is for opening air gap ring-type inductor schematic diagram.
Fig. 2 is for opening air gap ring-type inductor cutaway view.
Ring-shaped magnetic circle 1 is reeled by silicon steel strip and is formed, layer insulation, each layer from inside to outside is independent conductor, big outer little horn-like air gap 2 in cutter the cross section of ring-shaped magnetic circle 1 being split into, the plane of the vertical ring-shaped magnetic circle 1 in air gap 2 planes, interior collar extension angle α scope is 0 °＜α≤10 °, is wound with coil 3 on ring-shaped magnetic circle 1, and the shape of above-mentioned ring-shaped magnetic circle 1 can be annular, oval ring, square annular, polygon annular etc.
But in the utility model extensive use electric lighting and other industrial electrical equipment products, it is even to have a temperature rise, Long service life, low power consumption and other advantages.
