Abstract
The invention discloses an assembled single-phase reactor. A shell of a magnetic pot is formed by assembling two semicircular base plates positioned at two ends and a plurality of magnetic ring housings positioned between the two semicircular base plates; the shell of the magnetic pot and magnetic columns which are positioned in the magnetic ring housings and magnetically communicated with the two semicircular base plates together form an assembled magnetic pot; the magnetic columns are a plurality of series assembly structures; the shell of the magnetic pot and the magnetic columns are fixed with each other through passed bolts; one or two gaps for leading out wires is or are formed in the plurality of magnetic ring housings; foil winding coils are wound outside the magnetic columns; and a filling material is filled in a space in the pot body. By the assembled single-phase reactor, the technical problems that the conventional single-phase reactor product made of soft magnetic powder metallurgy materials and foil winding coils is low in electromagnetic compatibility and high in magnetic flux leakage, cannot change the capacity and the technical characteristic of the product conveniently, and the like can be solved.
Description
Technical field
The present invention relates to the single-phase reactor product that is applicable to use by high-frequency current of making around formula coil with a kind of soft magnetic powder metallurgical material and paper tinsel, specifically the metallurgical iron powder tank body of a kind of split mounting type soft magnetic powder paper tinsel is around single-phase reactor product.
Background technology
Be applied to the powder metallurgy iron powder core single-phase reactor of high frequency precision circuit and small power electric sub-industry, traditional mode of production is to coil on the ferrocart core of simple garden annular.Its shortcoming is that coil is exposed outside magnet, and cannot change easily product capacity and technical characteristic, and capacity is little and leakage field is large.
Summary of the invention
The object of this invention is to provide a kind of Assembled single-phase reactor, with solve the Electro Magnetic Compatibility that single-phase reactor product that traditional soft magnetic powder metallurgical material and paper tinsel make around formula coil exists poor, cannot change easily product capacity and technical characteristic, and the technical problem such as leakage field is large.
The technical scheme that the present invention realizes foregoing invention object is as follows:
A kind of Assembled single-phase reactor, by the semicircle base plate at two ends and the assembled shell that forms magnetic tank of several magnet ring shells between two semicircle base plates, shell by magnetic tank forms split mounting type magnetic tank jointly with the magnetic post that is positioned at magnet ring shell and two semicircle base plates of magnetic connection, described magnetic post is several series connection splicing structures, and the shell of described magnetic tank and magnetic post are fixed into one by the bolt passing; In described several magnet ring shells, there is one or two to have the breach of lead-out wire; Magnetic post is around with paper tinsel coiling, and the gap in described tank body is filled with filler.
The present invention is owing to adopting technique scheme, the integral prefabricatedization production of coil and the emc issue (EMC) in large power, electrically air circuit have been solved preferably, the electromagnetic radiation of inductance is had to anti-good shielding action, but also make the stable performance of reactor, insulation and heat-resisting stronger, produces more easy.Concrete advantage and effect are as follows:
1, adopt soft magnetic material to make ring-type, plate-like and column form part, use magnetic-conductive adhesive to adopt erection method that above-mentioned part is bonded to pot type.Annular element is used for forming shell, and column part is used for forming inner core, and half discoid part forms the upper and lower bottom plate of product.The shell of this tank body be the guard shield of this product be also magnetic track path, shell forms products pot city external form with inner magnetic post together with upper and lower cover plates, thereby forms the magnetic loop of a sealing.
2, this product need to form by increasing or reduce the quantity of shell magnet ring and inner magnet post the product of different capabilities due to what adopted that erection method can be according to reality.
3, by adjusting gap between assembled part, can change the magnetic resistance between magnetic parts, thereby change tank body magnetic permeability, also can be by adjusting the characteristic of binding material, the variation of the characteristic of soft magnetic material reaches this object, thereby realize the single-phase reactor product that assembles different technologies performance under the condition that does not change overall dimension.
4, the coil of this product adopts aluminium foil and the Copper Foil coiling of electrician's level to form, and with respect to wire-wound product, this product is specially adapted to use in high, medium and low frequency band, has the advantages such as temperature rise is low, noise is little, leakage field is little, coiling is simple.
5, coil adopts aluminium foil and Copper Foil coiling, and products with larger capacity adopts multilayer paper tinsel and is added with insulation film to reduce skin effect and the eddy current loss under high frequency around centre, reduces small product size simultaneously, has technique simple, the advantages such as flexible operation.Product leakage field is little, can not consider electromagnetic compatibility and the insulation distance of surrounding during installation.
6, split mounting type scheme makes each accessory size less, can adopt little tonnage press compacting soft magnetic tank part, saves equipment investment cost, improves the quality of products.
7, the coil of this product and tank body adopt epoxide resin vacuum pouring technology, make soft magnetic tank and coil be firmly bonded together moving, thermal stability is strong, long service life, electric parameter is stable not changed by any electric and environmental factor, adopts that H class F insulating material F is the highest bears 220 ℃ of high temperature continuous operations.

Embodiment
Concrete structure of the present invention is referring to accompanying drawing.The parts that adopt soft magnetic powder metallurgy to make comprise semicircle base plate, magnet ring shell and magnetic post, and the split mounting type soft magnetism pot type paper tinsel that is assemblied to form the rich formula coil of the built-in paper tinsel of pot type shell by them is around single-phase reactor.The metallurgical iron powder tank body of soft magnetic powder part is made by pressure processing by iron powder or iron silica-alumina material.
From Fig. 1,2, reactor integral body forms magnetic tank by magnetic core 3, magnet ring shell (barrier shield) 2, upper and lower base plate 1,5.Paper tinsel coiling is put into magnetic tank, by bolt 6, through fixing hole 4, whole magnetic tank is locked, and completes the composition of soft magnetism reactor.Adopt segmentation structure can freely adjust height with design capacity adjustment and adopt multilayer paper tinsel technique for coiling to realize the requirement to various capacity in electric power, electronic system.
Referring to Fig. 3, while utilizing the present invention to make reactor, a paper tinsel coiling is put into magnetic tank annular space, then two magnetic tank upper and lower bottom plates 1,5 are carried out to upper and lower involutory covering, on the magnet ring shell 2-1 of the top, have the breach that has two lead-out wires to form the reserved line outlet groove 9 of leading-out terminal.Two kinds of outlet methods of upper outlet or side outlet are optional, and shown in Fig. 2 is the structural representation of side line outlet groove 7.By line outlet groove 9, draw outlet terminal 10, then 4 li of fixing holes, put on bolt whole magnetic tank is tightened to one, the inner casting resin of barrier shield 2 at magnetic tank, adopt vacuum pouring technique to realize the bonding of integral body, this has just made a whole reactor, use performance is stable, and resistance to short-circuit capacity is strong.
Fig. 4 has omitted magnet ring shell (barrier shield) 2, the perspective view of the Assembled single-phase reactor being comprised of upper and lower bottom plate 1,5.
The present invention mainly should be in the powerful strong, weak electricity equipment industry of high, medium and low frequency band.
