Abstract
The utility model discloses a reactor iron core stem stem, including folding pile a plurality of iron core cakes of being in the same place, the iron core cake is folded the sign indicating number by the multi -disc silicon steel sheet and is formed, and the reactor stem stem is stacked by a plurality of iron core cakes and forms, and it is as an organic whole to put in order the solidification of post iron core through the resin pouring, the utility model discloses a reactor iron core stem stem, a plurality of iron core cakes that will constitute the iron core stem stem are wholly poured into a mould with the resin to curing molding, iron core stem stem after the shaping, again with upper and lower indisputable for the yoke resin bond, take such technology, the noise of reactor can reduce about 10dB.
Description
Technical field
The utility model relates to a kind of iron core stem stem for converting equipment, particularly a kind of as reactorThe multistage iron core stem stem of iron core column.
Background technology
Reactor is widely used in, in electrical power trans mission/distribution system equipment, realizing the effect of current-limiting protection; By with electricityContainer coordinates the effect that can also play inhibition, filtering appts harmonic wave, can effectively improve the quality of power supply of electrical network,Reduce the wastage, improve power factor etc. Due to the particularity of reactor, iron core stem stem is by multiple disconnectedThe silicon steel sheet code system of opening forms, and because stem stem disconnects, when reactor operation, noise is larger, so reactanceDevice noise is a problem of puzzlement reactor manufacturing firm always.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of iron core stem for reactor, reactor stem stem byMultiple iron core cakes stack together, and by resin-cast, whole column iron core are cured as to one, and the stem stem after moulding againCarry out bondingly with resin with upper and lower iron yoke, take such technique, the noise of reactor can reduce 10dBLeft and right.
Iron core stem for reactor of the present utility model, comprises iron core cake; Described iron core cake is by multi-disc silicon steel sheet stackCode forms, and iron core stem stem is stacked together by multiple iron core cakes, by resin-cast, whole column iron core is cured as to oneBody.
Further, described resin-coating is in the excircle of iron core cake.
Further, between adjacent iron core cake, separate by air gap backing plate.
Further, described air gap backing plate is epoxy plate.
Further, the cross section of described iron core cake is circular.
Further, described resin is not less than 3mm along iron core cake minimum thickness radially.
Further, each silicon steel sheet height of formation iron core cake is consistent.
Iron core stem for reactor of the present utility model, will form the iron core cake entirety resin-cast of iron core stem stem,And curing molding, after stacking, carry out bondingly with upper and lower iron yoke resin again, take such technique, electricityThe noise of anti-device can reduce 10dB left and right.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Fig. 1 is structural representation of the present utility model; Fig. 2 is the top view of Fig. 1, as shown in the figure: this realityExecute routine iron core stem for reactor, comprise the multiple iron core cakes 1 that are stacked together; Described iron core cake 1 is by manySheet silicon steel sheet stack code forms, and is poured into a mould whole column iron core is cured as to one by resin 2; Whole column iron core refers toThe multiple iron core cakes 1 that are stacked together, stem stem diameter is Φ 295mm; Described iron core cake 1 is by multi-disc silicon steel sheetFolded code forms, and carries out colligation and fix, and the iron core cake after multiple colligations is stacked and becomes an integrated iron core corePost, and be integrated by resin 2 cast cured explosives; The height of iron core cake 1 is 85mm, and adopting is highly 85mmSilicon steel sheet stack code form, iron core cake cross section is made up of multistage (width do not wait) silicon steel sheet, iron core cake 1The silicon steel sheet width adopting must not exceed the inscribed circle size of stem stem diameter of phi 295mm, and by each iron core cakeCarry out colligation and fix, then the stem stem that the iron core cake after multiple colligations is stacked, resin 2 cast cured explosives adoptedBe integrated, can make the noise of reactor can reduce 10dB left and right.
In the present embodiment, described resin 2 is coated on the air gap between excircle, the iron core cake of iron core cake 1;Casting process completes by mould. Between casting mold and iron core, there is certain gap, resin filled to mould,Pass through again hot setting, last moulding.
In the present embodiment, between adjacent iron core cake 1, separate by air gap backing plate, make reactance value be similar to gasGap Magnetic circuit characters, i.e. impedance is directly proportional substantially to electric current, and air gap adopts air gap backing plate to do interval, can ensure electricityAnti-device air gap does not change in running.
In the present embodiment, described air gap backing plate is epoxy plate; Shrinkage is low, and mechanical property is good, can ensureReactor air gap does not change in running.
In the present embodiment, the cross section of described iron core cake 1 is circular.
In the present embodiment, described resin 2 is not less than 3mm along iron core cake 1 minimum thickness radially, and structure is steadyQualitative good, not fragile, the cylindrical of resin 2 is circular, can simplify mould structure, is convenient to moulding.
In the present embodiment, each silicon steel sheet height that forms iron core cake 1 is consistent.
Finally explanation, above embodiment is only unrestricted in order to the technical solution of the utility model to be described,Although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art shouldWork as understanding, can modify or be equal to replacement the technical solution of the utility model, and not depart from this realityBy aim and the scope of new technique scheme, it all should be encompassed in the middle of claim scope of the present utility model.
