Description
(1) technical field:
The utility model relates to a kind of improvement of air core reactor, particularly about a kind of series-parallel air core reactor.
(2) background technology:
Existing air core reactor, as the wrapped air core reactor of epoxy resin, all adopt multilayer and around structure.The width of cloth of this kind reactor winding depends primarily on size of current by reactor to thickness, under identical current density, the reactor of same inductance value, the consumption of its winding electric conducting material, active loss may be inequality fully, when the cross section of winding is that the ratio of square and the foursquare length of side and winding average diameter is most economical during for constant, just design the optimum value of this kind reactor, it is poor more that optimum value departs from big more its economy therewith.Because the width of cloth of existing air core reactor coil is to height and the average diameter of thickness much smaller than winding, therefore the consumption of winding electric conducting material and active loss and optimum value fall far short, and electric current is small size more more little with the ratio of winding average diameter to thickness, so economy is poor more.
(3) summary of the invention:
The purpose of this utility model is the defective that exists on the existing air core reactor structure, with the width of cloth that increases the air core reactor coil to thickness approach, make the electric conducting material consumption and the active loss trend optimum value of air core reactor, thereby reach the consumption that reduces electric conducting material, reduce active loss, dwindle overall dimension, the purpose of weight reduction.
Design of the present utility model is: organize series-parallel air core reactor, it is made up of lead-in line row, outlet row and coil more, it is characterized in that arranging in parallel with lead-in line row and outlet respectively after a plurality of coil series connection; A plurality of coils are in parallel with lead-in line row to be one group, in parallel with outlet row respectively after every group of corresponding coil connected respectively; Be in parallel with lead-in line row and outlet row respectively after the different layers windings in series.
The design feature of above-mentioned design is to be together in series earlier between coil or between winding, be connected in parallel on respectively again on lead-in line row and the outlet row, after too much group is connected, series connection group number is multiplied, also promptly increase the width of cloth of winding to size, make the width of cloth level off to the height and the average diameter of winding, make product structure trend optimum value to thickness.Be to have adopted different layers windings in series structure in parallel again that winding can be adopted with a kind of lead again, changed every layer of labyrinth that will adopt different conductor, the different numbers of turn, make effect thereby improve, make the air core reactor overall dimensions reduce 1/2, weight saving is more than 1/3, and active loss also reduces 1/3.Also expand the scope of application of air core reactor, as in cabinet, installing and using, and replaced core-type reactor etc.
