Description
Technical field
The utility model relates to a kind of electric components, particularly a kind of iron core reactor.
Background technology
At present, known iron core reactor, mainly comprise upper yoke, lower yoke, be provided with at least one group of winding between upper yoke and the lower yoke, be provided with stem stem in the hollow space of winding, upper yoke lower yoke and stem stem are formed by stacking by the metal material of number of plate-shaped, and the outside of upper yoke, lower yoke is provided with and presses down beam, on press down between beam to adopt and draw screw rod that stem stem is fastening; Winding is rounded by the cross section, the copper cash of flat or aluminum steel coiling form.This iron core reactor generally air gap between upper yoke, lower yoke and stem is bigger, and dispersion loss is also very big, draws the existence of steel constructions such as screw rod, folder to make stray loss very big accordingly, also has certain eddy current loss in the conductor structure winding.Can't satisfy current energy-saving and cost-reducing trend.
The utility model content
In order to overcome the deficiency of the high loss of existing iron core reactor, the utility model provides a kind of low-loss iron core reactor of brand new, and its loss is reduced.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of low-loss iron core reactor, comprise upper yoke, lower yoke, be provided with at least one group of winding between upper yoke and the lower yoke, be provided with stem stem in the hollow space of winding, upper yoke, lower yoke and stem stem are formed by stacking by the metal material of number of plate-shaped, be fitted with two arm-ties of making by low-permeability material in the hollow space of winding, two arm-ties correspondence respectively are arranged on upper yoke, the both sides of lower yoke and stem stem, upper and lower between two arm-ties is respectively equipped with runs through upper yoke, the through hole of lower yoke, be provided with in two through holes run through screw rod and by nut with upper yoke, lower yoke and stem stem clamp, and run through screw rod, nut and corresponding upper yoke, lower yoke, be provided with insulation cushion between the arm-tie.
Compared with prior art, the utility model has been cancelled steel structures such as drawing screw rod, folder from top to bottom, pressure beam and pad pin, and arm-tie adopts the material of low permeability to make, and clamps with running through screw rod, can reduce eddy current loss; The path of insulation cushion linkage eddy current capable of blocking has reduced stray loss.The utility model has also been simplified the structure of reactor simultaneously, has reduced manufacturing cost, and its field of employment is identical with the field of employment of existing iron core reactor, is used in the low-frequency channel, to suppress the electric current variation or to make the alternating current phase shift more.
As further improvement of the utility model, stem stem is separated into plurality of sections in the longitudinal direction, is separated by insulation board between each section.This scheme can subtract the air gap between upper yoke, lower yoke and the stem stem, can reduce stem stem dispersion loss and noise.
Winding can adopt Copper Foil or aluminium foil coiling to form, and can effectively improve the winding activity coefficient, reduces the eddy current loss in the winding.
