Specific implementation mode

Below in conjunction with drawings and embodiments, the utility model is described in further detail.

Please refer to Fig. 1 and Fig. 2, a kind of low pressure magnetic-ring reactor, including reactor body 1, N number of reactor Ontology 1 forms a magnet ring group, wherein 6<N<15, N values described in the present embodiment are 10, i.e. 10 formation of reactor body 1 One magnet ring group further includes babinet 3 and insulation board 4, and several magnet ring groups are fixed on by fixing bolt 6 in the babinet 3, It is provided with insulation board 4 on the cabinet wall to separate, the insulation plate thickness is 2mm, for preventing enameled wire and 3 shell of babinet straight Contact plays insulation and avoids generating the effects that vortex causes babinet 3 to generate heat.

The reactor body 1 is the cylindrical shape of hollow out, and the reactor body 1 is made of powder core material, magnetic powder Core is a kind of soft magnetic materials made of mixing compacting with dielectric by ferromagnetism powder.Due to ferromagnetic particle very little（High frequency Lower use is 0.5~5 micron）, and separated by non magnetic electrical insulating film substance, therefore, powder core can both completely cut off vortex, It is suitable for upper frequency again；On the other hand due to the channel effect between particle so that magnetic powder core material have low permeability and Permanent permeance；Magnetic core material particle size is small, do not occur substantially collect skin phenomenon, magnetic conductivity with frequency variation also just compared with For stabilization.It is mainly used for high-frequency inductor, the magnetic electricity performance of powder core depends primarily on the magnetic permeability of powder material, the size of powder With shape, their fill factor, the content of dielectric, briquetting pressure and heat treatment process etc..In the present embodiment, our magnetic Ring reactance uses the Fe-Si-Al magnetic core material that electric property is best in magnetic powder core material, and iron Si-Al Magnetic Powder Core is by Al, Si, Fe powder It constitutes, mainly substitutes ferrocart core, loss ratio ferrocart core low 80%.It can be used under 8kHz frequencies above；Saturation magnetic strength exists 1.05T left and right；Magnetic permeability is from 26~125；Magnetostriction coefficient is close to 0, and noiseless generates when working at different frequencies； There are higher DC biasing abilities than MPP；With the best ratio of performance to price.It is mainly used in AC inductance, outputting inductance, circuit Filter, power factor correction circuit etc..Sometimes also substituting has air gap ferrite to make transformer core use.

It is wound with a bundle of enameled wire 2 in each reactor body 1；Described a bundle there is 20-30 roots enameled wire 2, and every The production length of a piece enameled wire 2 is 4-5m, and in the present embodiment, the length of the enameled wire 2 is 4.5m, has for described a bundle and to include 25 enameled wires 2；2 specification of the enameled wire is：Diameter 1mm, F class B insulation.It is connected with terminals at the both ends of the enameled wire 2 Son 5 with three-phase alternating current for being electrically connected.

A bundle of 2 one end of enameled wire alignment is tied up by insulated wire, and the distance for being then spaced Am is tied again using insulated wire It pricks once, wherein the value range of the A is 0.8-1.2m, the value of A described in the present embodiment is 1m.A bundle of enameled wire 2 is whole Magnet ring group is pierced into neat one end, and the other end is close to the close coiling of bunchy inside and outside reactor body, coiling multiturn, in winding process, Enameled wire bunchy, circle should be kept closely to be close to turn-to-turn, harness is close to reactor body inside and outside wall；Often around two circles, insulating bar is used It pierces into magnet ring group through inner, pressure is firmly rolled, to keep magnet ring group to have unobstructed air duct.

Remove Static Electro sensibility reciprocal of the magnet wire insulation layer for measuring reactor, reactor in enameled wire both ends end If Static Electro sensibility reciprocal should meet the requirements reactor static inductance numerical quantity difference it is larger, can pass through adjust reactor coiling circle Number carrys out adjusting inductance numerical value.

The utility model can not only completely cut off vortex using magnetic powder core material, but also be suitable for upper frequency；Powder core reactance Channel effect between grain makes it have low permeability and permanent permeance；Powder core particle size is small, does not collect substantially Skin phenomenon, magnetic conductivity are relatively stable with the variation of frequency；It is mounted in shunt capacitor cabinet when this magnetic-ring reactor is used in series, Temperature lifts low, low noise, and the inductance value of output is more stablized compared to traditional silicon steel sheet material；Low, loss ratio ferrocart core is lost Low 80%.
