Abstract
The invention discloses a resonance reactor for an electric locomotive. A coil (1) has a double cake parallel connection structure; upper and lower magnet yokes (2) and a side magnet yoke (30 are formed by laminating and pressing silicon steel sheets; the upper and lower magnet yokes (2) are tensioned by clamp pieces (4) and screws (5); and the coil (1) is clamped between the upper and lower magnet yokes (2). The resonance reactor has a small volume and high inductance linearity, and is low in noise, a production process is simple, and inductance adjustment is not needed.
Description
Technical field
The present invention relates to the railway locomotive manufacturing technology, relate in particular to a kind of use for electric locomotive resonance air core reactor.
Background technology
Resonance reactor after the resonant capacitance in the unsteady flow cabinet is connected, is parallel to the intermediate dc loop of unsteady flow cabinet as the vitals of AC transmission electric power locomotive, constitutes the secondary filtering circuit, is used for the secondary power pulsation that absorption mesh side single-phase voltage causes.In general, this reactor has two kinds of structures.A kind of is iron core formula structure, and the silicon steel sheet that promptly adopts the normal lamination formula is as iron core, and coil is enclosed within on the iron core column.Adopt this iron core formula structure, when the high-frequency harmonic electric current of induction flow through, iron core can generate heat because of electromagnetic eddy, sends very big noise and vibration because of air gap is arranged between the iron core.Another kind is a hollow core structures, does not promptly have the pure loop construction of iron core.Adopt this open core structure, can produce strong electromagnetic interference surrounding environment, and bulky, can't be installed in the oil tank of transformer.
Summary of the invention
The object of the invention overcomes the deficiency of above-mentioned prior art exactly, provides that a kind of volume is little, noise is low, production technology is simple, the inductance value good linearity, need not to transfer the use for electric locomotive resonance reactor of sense.
The objective of the invention is existing like this: a kind of use for electric locomotive resonance reactor; Coil (1) is two cake formula parallel-connection structures; Upper and lower yoke (2), side magnetic yoke (3) are used the silicon steel plate stacking moulding; It is characterized in that upper and lower yoke (2) uses folder (4) by screw rod (5) tension respectively, coil (1) is sandwiched in the middle of the upper and lower yoke (2).
Adopt scheme of the present invention, coil is two cake formulas, owing to there is not iron core air gap, noise reduces greatly, and production technology is simple, the inductance value good linearity.Have the characteristic of good linear inductance, volume is little, compact conformation.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer; To combine the accompanying drawing in the embodiment of the invention below; Technical scheme in the embodiment of the invention is carried out clear, intactly description; Obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
Below with accompanying drawings embodiment of the present invention.As shown in Figure 1: the resonance reactor of present embodiment, its coil (1) adopt two cake formula structures.Upper and lower yoke (2), side magnetic yoke (3) are to use the silicon steel plate stacking moulding, constitute a degree of lip-rounding frame, as the path of the outside magnetic flux of coil (1).By screw rod (5) tension folder (4), coil (1) is sandwiched in upper and lower yoke (2) centre.Lead-in wire (6) is positioned at a side of coil (1).Owing to there is not the air gap of core-type reactor, so after coil turn confirmed, inductance value also just was fixed up, and need not to adjust again.
What should explain at last is: above embodiment is only in order to explaining technical scheme of the present invention, but not to its restriction; Although with reference to previous embodiment the present invention has been carried out detailed explanation, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these are revised or replacement, do not make the spirit and the scope of the essence disengaging various embodiments of the present invention technical scheme of relevant art scheme.
