Abstract
The invention discloses a casting type power extraction coil structure and a preparation method thereof. The method comprises the steps of: winding alkali-free glass cloth on a rectangular column mold with rounded four corners, then winding a polyester film on the alkali-free glass cloth, and then winding a conducting wire on the polyester film; then orderly winding the polyester film and the alkali-free glass cloth after the winding of the conducting wire is finished; then winding an insulating layer at the upper end and the lower end of a coil respectively; and finally, demolding the wound coil, placing the wound coil in a rectangular casting mold of which the shape is the same as the coil and the volume is slightly greater than that of the coil, and using an epoxy resin for vacuum casting in a vacuum casting tank to ensure that the coil becomes a whole. The casting type power extraction coil structure prepared by the method solves the problems existing in the coil with a conventional structural type, has a simple and convenient winding method, and provides the guarantee for the safe operation of a power extraction shunt reactor.
Description
Technical field
The present invention relates to a kind of reactor winding structure and preparation method, particularly a kind of take out can shunt reactor in rectangle power extraction coil structure and preparation method.
Background technology
Continuous development innovation along with the reactor technical field, a kind of both can output reactive power, in the time of the compensation network capacitance current, can extract part energy out again, as active power, be used for throwing light on or the reactor of other household electricity-take out and to come out by shunt reactor.Take out the realization of energy function, mainly be by increase some circle coils at common iron core of electric reactor, when reactor is worked, magnetic flux passes coil and produces induced potential, in illumination (or other) loop, producing electric current again, so just drawn a part of meritorious energy. we call power extraction coil to such special coil.Because the core section of reactor mostly is rectangle, therefore, power extraction coil if adopt the winding method of conventional layer coil and with insulating paper as insulation system, its mechanical strength is difficult to guarantee, install and fix difficulty, can't bear bigger short-circuit electromotive force, bring hidden danger for the safe operation of reactor.
Summary of the invention
The present invention is directed to the existing mechanical strength of power extraction coil that adopts conventional winding method preparation and be difficult to guarantee, install and fix difficulty, can't bear bigger shortcomings such as short-circuit electromotive force, a kind of new casting type power extraction coil structure and preparation method are provided.
For reaching above purpose, the present invention takes following technical scheme to be achieved:
A kind of casting type power extraction coil structure comprises the coil of lead coiling it is characterized in that this coil section is the straight-flanked ring of four rounding of angle that the coil inboard is sequentially set with insulating barrier from lead in straight-flanked ring: polyester film, alkali-free glass cloth; The coil outside is sequentially set with insulating barrier from lead outside straight-flanked ring: polyester film, alkali-free glass cloth; The coil upper and lower end is provided with insulating barrier; The outside and upper and lower end insulating barrier all are cast with epoxy resin in the described coil, make coil become as a whole.
In the such scheme, described alkali-free glass cloth is two-layer, is provided with the alkali-free glass felt between this two-layer alkali-free glass cloth.Described coil upper and lower end insulating barrier is the alkali-free glass felt.
A kind of preparation method of above-mentioned casting type power extraction coil structure comprises the steps: at first coiling alkali-free glass cloth on the rectangular column mould of four rounding of angle, again coiling polyester film on alkali-free glass cloth, coiling lead on polyester film then; After the lead coiling is finished, coiling polyester film, alkali-free glass cloth successively again; Follow upper and lower side difference coiling insulating barrier at coil; After at last that coiling is the good coil demoulding, it is identical with coil to put shape into, and volume is a bit larger tham in the rectangle casting mold of winding volume, carries out vacuum pouring with epoxy resin in the vacuum pouring jar, makes coil become as a whole.
In the said method, described alkali-free glass cloth coiling is two-layer, two-layer between folder one deck alkali-free glass felt.The insulating barrier of the upper and lower side coiling of described coil is the alkali-free glass felt.
Adopt the cast-type rectangle power extraction coil structure of the inventive method preparation to solve the existing problem of traditional structure pattern coil fully, and winding method is simple and convenient, guarantee is provided for the safe operation of taking out the energy shunt reactor.

Embodiment
The present invention is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, a kind of casting type power extraction coil structure, the coil that comprises lead 4 coilings, this coil section is the straight-flanked ring of four rounding of angle, and the coil inboard is sequentially set with insulating barrier polyester film 1, alkali-free glass cloth 2, alkali-free glass felt 3, alkali-free glass cloth 2 from lead 4 in straight-flanked ring; The coil outside is sequentially set with insulating barrier polyester film 1, alkali-free glass cloth 2, alkali-free glass felt 3, alkali-free glass cloth 2 from lead 4 outside straight-flanked ring; The coil upper and lower end is provided with alkali-free glass felt 3; Outer insulation and upper and lower end alkali-free glass felt 3 all are cast with epoxy resin 5 in the coil, make coil become as a whole.
The preparation method of above power extraction coil structure, coiling alkali-free glass cloth 2 on the rectangular column mould of four rounding of angle at first, coiling alkali-free glass felt 3 on alkali-free glass cloth 2, coiling alkali-free glass cloth 2 again on alkali-free glass felt 3; Coiling polyester film 1 on alkali-free glass cloth 2 then; Coiling lead 4 on polyester film 1 then; After lead 4 coilings are finished, draw tap, coiling polyester film 1, alkali-free glass cloth 2, alkali-free glass felt 3, alkali-free glass cloth 2 successively again are connected tap then that (one of them joint marker is a with connector lug 6
m, another joint marker is X).The upper and lower end parts of coil 4 is used 3 coilings of alkali-free glass felt respectively.After lead 4 the coil demoulding that coiling is good, it is identical with coil to put shape into, and volume is a bit larger tham in the rectangle casting mold of winding volume, carries out vacuum pouring with epoxy resin 5 in the vacuum pouring jar, makes coil become as a whole (as shown in Figure 3).
The advantage of the cast-type rectangle power extraction coil structure of the present invention's preparation is:
1, fire-retardant. Epoxy resin is the insulating cement of base-material, because the difficult right property of himself, thereby can be not combustion-supporting when breaking out of fire.
2, firm in structure. The coil surface bag is with the multilayer insulation encapsulated layer, thus the raising of the mechanical strength of coil, thereby the also corresponding raising of Short Circuit withstand intensity.
3, safe. Coil solidifies as a whole with epoxide-resin glue, so coil can turn-to-turn short circuit not occur because of the reactor Long-term Vibration.
4, easy for installation. The loop construction cross section is four jiaos and leads round straight-flanked ring, conforms to the iron core of electric reactor cross section, and in addition, because coil has certain rigidity through poured with epoxy resin, so coil installs and fixes conveniently.
