Abstract
The invention relates to a reactor. The reactor comprises two groups of hollow coils, two iron yokes made of ferromagnetic materials and a clamping part, wherein the coil groups are connected in series; each coil group can be formed by one or more coils which are connected in parallel or in series; the section of each coil can be made into any shape, the heights of the coils can be equal or unequal, and the winding directions of the coils can be the same or reverse. The reactor has the advantages that except the upper iron yoke and the lower yoke, the magnetic flux outside the coils is basically neutralized, so that the electromagnetic interference to the ambient environment is basically eliminated and the linearity of coil inductance is also greatly improved; the structure is simple and the manufacture is simple and convenient.
Description
Technical field
The present invention relates to a kind of reactor, be mainly used for the reactor of electric power system.
Background technology
Existing reactor generally has following two types: a kind of is the iron-core coil being with air gap, its objective is to utilize in iron core and contain air gap to improve the linearity of voltage-current characteristic, but during this kind of reactor work, noise is very large, and the linearity of voltage-current characteristic can not keep good in full voltage range; Another kind of reactor not ribbon core, and coil is an entirety, but this kind of reactor volume is large, causes very large electromagnetic interference during work to surrounding environment, and ferromagnetic substance around also seriously affects the inductance value of reactor.
Summary of the invention
The object of this invention is to provide one without electromagnetic interference, inductance value calculation accuracy is high, and the linearity of voltage-current characteristic keeps well in full voltage range, and structure is simple, and volume is little, the reactor that during work, noise is little.
The present invention is achieved in that a kind of reactor, comprises two groups of air core coils, two iron yokes made with ferromagnetic material, folder.Coil groups is series connection, and often group can by one or more coils from parallel connection of coils or in series, and the cross sectional shape of each coil is arbitrary, and height can not wait or not etc., around to can be identical or contrary.
Coil outer of the present invention, except magnetic flux all basic neutralisations of upper and lower iron yoke, essentially eliminates the electromagnetic interference to surrounding environment, substantially increases again the linearity of coil inductance, and structure is simple, simple for production.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention
Embodiment
Below in conjunction with drawings and Examples, the present invention is further elaborated.
As shown in Figure 1, a kind of reactor, comprises coil 1 and 2, iron yoke 3 and 4, folder 5.Described coil is by wire being wound in two air core coils, its shape being fixed by boiling hot paint; Make upper and lower iron yoke 3,4 with two groups of ferromagnetic materials, the coil of having shaped is placed between two iron yokes 3,4, and with folder 5, two groups of coil clamps are located between upper and lower iron yoke 3,4; Finally fix with bolt 6, nut 7.Coil 1 and coil 2 are series connection, and its connected mode is for when alternating current passes through, and the flow direction that their produce is contrary.
When the coil midstream of reactor crosses alternating current, because the flow direction produced in two coils 1,2 is contrary, make at all local magnetic flux all basic neutralisation of coil outer except upper and lower iron yoke 3,4, thus main flux can only pass through in the inside of two coils 1,2, namely magnetic circuit forms loop by the inside of two coils 1,2 and upper and lower iron yoke 3,4, the air gap that its path is coil height primarily of two length is formed, and the magnetic in two iron yokes 3,4 is close very little, and therefore the linearity of coil inductance is very good.Again because this length of magnetic path is fixing, can not be diffused into that other is local, thus to around without electromagnetic interference, winding inductance quantity is not also subject to the impact of surrounding environment (as there is ferromagnetic material around).
