Abstract

The utility model discloses a magnetic-ring reactor which has the advantages of simple structure and small volume, can be used for reducing magnetic-field interference of surrounding instruments and meters. The magnetic-ring reactor comprises a base (1), an aluminum shell shielding layer (2) and a wiring terminal (6) arranged outside the aluminum shell shielding layer (2). At least one single reactor body is contained in an inner cavity of the aluminum shell shielding layer (2); and epoxy resin (7) is filled in a remained space. The single reactor body comprises a plurality of overlapped magnetic rings (3) and a coil winding (5) which is wound on the overlapped magnetic rings (3), and a tap of the coil winding (5) is connected with the external wiring terminal (6). The magnetic-ring reactor disclosed by the utility model is widely applied to an active power filtering device.

Description

The magnet ring reactor

Technical field

The utility model relates to a kind of magnet ring reactor.

Background technology

The reactor product that is adopted in the present known active electric filter device is an air core reactor, and it is formed by multiply transposition copper cash or aluminum steel coiling, and it is more to consume copper cash or aluminum steel; Processing technology is complicated, and cost is higher, and caloric value is big; Load loss is bigger, and efficient is lower, and its magnetic field is to instrument, instrument are disturbed bigger on every side; Volume is bigger, does not meet the energy-saving and cost-reducing requirement that country proposes.

The utility model content

The utility model technical problem to be solved is the deficiency that overcomes prior art, provides a kind of simple in structure, and volume is little, reduces the magnet ring reactor of the magnetic interference of instrument, instrument on every side.

The technical scheme that the utility model adopted is: the utility model comprises base and aluminum hull screen and the outside binding post of aluminum hull screen; The inner chamber of said aluminum hull screen accommodates at least one reactor monomer; Be perfused with epoxy resin in its complementary space; Said reactor monomer comprises a plurality of magnet rings stacked together and is wound on the coil windings on said a plurality of magnet ring stacked together that the tap of said coil windings is connected with outside binding post.

Further, also be wound with the fixed band that one deck is used for fixing the mutual alignment of the magnet ring that is in range upon range of state between said magnet ring and the coil windings.

More concrete, said fixed band is PET insulating tape, glass fiber adhesive tape or contraction bands.

Generally comprise three above-mentioned reactor monomers at magnet ring reactor described in concrete the application.

The beneficial effect of the utility model is: because the utility model comprises base and aluminum hull screen and the outside binding post of aluminum hull screen; The inner chamber of said aluminum hull screen accommodates at least one reactor monomer; Be perfused with epoxy resin in its complementary space; Said reactor monomer comprises a plurality of magnet rings stacked together and is wound on the coil windings on said a plurality of magnet ring stacked together that this reactor adopts such structure just can adopt novel magnetic material (ferrocart core magnet ring such as Sendust Cores) to reach less relatively copper cash, greatly reduces the product load loss; Promote product efficiency; Reduce magnetic field to the influence of instrument, instrument on every side, reduce small product size, for the active electric filter device miniaturization lays the foundation; Simultaneously also greatly reduce production cost of products, meet the energy-saving and cost-reducing requirement that country proposes.Therefore the utility model is applied in the active electric filter device, generally speaking has following advantage:

1. simple in structure, loss is low, and volume is little;

2. its inductance value is a constant in bigger electric current multiple scope;

3. have magnetic masking layer (aluminum hull screen), the magnetic field in space around having weakened greatly, instrument, instrument around guaranteeing do not receive magnetic interference;

4. greatly reduce product cost.

Embodiment

As shown in Figure 1; The utility model comprises the binding post 6 of base 1, aluminum hull screen 2, magnet ring 3, fixed band 4, coil windings 5, epoxy resin 7 and aluminum hull screen 2 outsides, and its concrete internal structure is: said aluminum hull screen 2 is fixedly set on the base 1, and its inner chamber accommodates three reactor monomers; Be perfused with above-mentioned epoxy resin 7 in its complementary space around the reactor monomer; Each reactor monomer all comprises a plurality of magnet rings 3 stacked together and is wound on the coil windings 5 on said a plurality of magnet ring 3 stacked together that also be wound with the fixed band 4 that one deck is used for fixing the mutual alignment of the magnet ring 3 that is in range upon range of state between this magnet ring 3 and the coil windings 5, the tap of said coil windings 5 is connected with outside binding post 6; The magnet ring 3 of present embodiment adopts the ferrocart core magnet ring; Sendust Cores etc. for example, fixed band 4 adopts PET insulating tapes, glass fiber adhesive tape or contraction bands etc., and present embodiment adopts the PET insulating tape; Coil windings 5 is multiply enamelled wire or silk-covered wire; The line footpath of considering multiply enamelled wire (or silk-covered wire) is soft, and the bar number is more, and the big problem of insulating paint difficulty is removed in tap; So often select polyurethane enamelled wire or silk-covered wire for use, to reach the purpose that tap coating removal technology is simple, the tab terminal contact is good.

Reactor monomer structure as shown in Figure 2; A plurality of ferrocart core magnet rings 3 are superimposed together up and down; Use PET insulating tape 4 (or contraction bands) with the half lap form a plurality of ferrocart core magnet rings 3 that are superimposed together to be twined a circle along circumference again, the technique for coiling requirement of then the multiply silk-covered wire or the enamel-cover twisted wire (coil windings 5) of appropriate size, quantity, length being followed magnetic ring coil by the number of turn of designing requirement is wound on the ferrocart core magnet ring 3 that has twined PET insulating tape 4 (or contraction bands); According to the line length that goes out of designing requirement, reasonably cut out tap length, and peel off the glass fiber on the winding wire multiply silk-covered wire again, pressing the binding post 6 of appropriate size; The tap of pressing good binding post 6 is immersed in appropriate depth in the scaling powder, proposes and immersed solder line bag tap in the solder furnace that is warmed up to suitable temperature, tap line is contacted with binding post 6 well; Consider the problem of high-frequency noise influence in service of reactor winding and winding insulation intensity simultaneously, after carrying out Preliminary detection, the semi-finished product that meet performance requirement are soaked F class F insulation oil, baking processing; To flood F class F insulation oil and three good of reactor monomers of baking processing again and put aluminum hull screen 2 into, and encapsulated epoxy resin 7 is handled.
