Abstract
The utility model discloses a composite magnetic core of a soft magnet; a nano-crystalline magnetic core is sleeved in the cavity of a ferrite magnetic core along the axial direction, or stacked with the ferrite magnetic core; the ferrite magnetic core can be also a Fe-based amorphous magnetic core; and the two magnetic cores are arranged in a protection box. The composite magnetic core is combined with the amorphous magnetic core or the ferrite magnetic core and the nano-crystalline magnetic core, which can not only meet the performance requirements of high- and low-frequency ends, but also meet the performance requirements of AC and DC, thereby reducing the process, the size, the weight, and most importantly reducing the production cost.
Description
Technical field
The utility model belongs to electrical equipment material technology field, and the soft magnetism that specifically is the instrument transformer among a kind of EMI coil that is applied to power supply, filter inductance, the CT is in conjunction with magnetic core.
Background technology
Traditional soft magnetic material magnetic core, be the soft magnetic core of homogenous material, because its intrinsic characteristic, its performance does not satisfy the requirement (comprising direct current or exchange status) of frequency end or current system, and in the middle of making, exist technology various, problems such as the part volume is big, heavyweight vehicle.
The utility model content
It is simple that the purpose of this utility model provides a kind of technology, the soft magnetism composite cores that volume is small and exquisite.Amorphous, nanocrystalline material combine magnetic core with soft magnetic material.
The technical solution of the utility model is; a kind of soft magnetism composite cores comprises the magnetic core of nanocrystalline material formation and the magnetic core that Ferrite Material constitutes, and it is characterized in that; nanocrystalline magnet core is sleeved on along vertical axial in the cavity of FERRITE CORE, and these two kinds of magnetic cores are installed in the protection box.
As another kind of implementation of the present utility model, described nanocrystalline magnet core also can stack setting with FERRITE CORE, and these two kinds of magnetic cores are installed in the protection box.
The above-described magnetic core that is made of Ferrite Material also can be the magnetic core that is made of the iron based amorphous material.
Above-described protection box is a plastic cement protection box.
The utility model is combined with nanocrystalline magnet core by amorphous magnetic core or FERRITE CORE, can satisfy low-and high-frequency end performance requirement, also can satisfy the performance requirement of alternating current-direct current, reduce technology, reduced volume, alleviated weight, most importantly reduced production cost.
