Abstract
The invention discloses an annular air gap ferrite core. The annular air gap ferrite core comprises an annular magnetic core body and an air gap, wherein the air gap of a proper length is formed in the annular magnetic core body to meet the requirements of a transformer and an inductor, and the length of the air gap is worked out according to the initial permeability of the annular magnetic core body, the size of the annular magnetic core body and the target effective magnetic permeability. The annular air gap ferrite core resolves the problems that the saturation resistance to alternating and direct current of products in the same class is poor, the products can not be applied to the inductor, the section area of a magnetic circuit is not consistent, the magnetic flux density is not consistent, a redundant magnetic core part exists, and loss is high.
Description
Technical field
The present invention relates to a kind of FERRITE CORE, particularly relate to a kind of annulus gap FERRITE CORE.
Background technology
Existing for making transformer, the FERRITE CORE of inductance has the shape such as annular and EE type, EI type, UU type, PQ type.The shapes such as EE type, EI type, UU type, PQ type belong to open circuit magnetic core, according to the needs of transformer, inductance, have the way opening air gap or cushion steam gap at the open circuit such as EE type, EI type, UU type, PQ type magnetic core center pillar, but there is magnetic core redundancy section and the high problem of loss.Toroidal core belongs to closed magnetic core, to the anti-saturation poor ability of AC and DC electric current, is not suitable for reactor, inductor.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of annulus gap FERRITE CORE is provided, make annulus gap FERRITE CORE strong to the anti-saturation ability of AC and DC electric current, reactor, inductor can be applied to.
For completing above-mentioned purpose, the technical solution used in the present invention is: in toroidal core, output the air gap of place's appropriate length to meet the needs of transformer, inductance, gas length is calculated by toroidal core initial permeability, toroidal core size, target effective magnetic permeability.
Beneficial effect of the present invention: make that magnetic circuit sectional area is consistent, magnetic flux density is consistent, eliminate redundancy magnetic core part, reduce the wastage, make inductance possess stronger anti-saturation ability to ac and dc current, reactor, inductor can be applicable to.
Accompanying drawing explanation
Below in conjunction with embodiment, the present invention is described in detail.
Fig. 1 is a kind of structure chart of annulus gap FERRITE CORE.
In figure: 1, toroidal core, 2, air gap.
Embodiment
