Description

Single-phase amorphous alternating current-direct current reactance device
Technical field
The utility model relates to a kind of single-phase amorphous alternating current-direct current reactance device, and rated operational current 30-250A scope, can be used in frequency converter, and the utility model belongs to electric automobile built-in reactor structure-design technique field.
Background technology
As shown in Figure 1, for the single-phase amorphous AC and DC electric automobile built-in reactor structural representation between traditional rated operational current 30-250A, the single-phase amorphous AC and DC electric automobile built-in reactor between described traditional rated operational current 30-250A is comprised of winding 11, skeleton 12, the first amorphous iron core 13, the second amorphous iron core 14, air gap plate 15 and stainless steel band 16.Winding 11 (two-layer or multi-layer flat winding) is directly flat to be processed into after coil on skeleton 12, then is arranged on the first amorphous iron core 13, the second amorphous iron core 14, and adds air gap plate 15, finally with stainless steel band 16, fixedly assembles.Its shortcoming is: one or more keeps flat and is wound on skeleton to use tape insulation copper strap wire, and general coiling multilayer, is unfavorable for reactor heat radiation; In the middle of amorphous iron core structure adopts, a place disconnects and adds air gap, causes single place air gap larger, and the loss of air gap place is large, and the heating of air gap place is serious, has limited reactor power, can not meet more large power, electrically electrical automobile mileages of continuation requirement.
Summary of the invention
The purpose of this utility model is to provide that a kind of efficiency of assembling is high, air gap loss is little, can meet the single-phase amorphous alternating current-direct current reactance device that the larger inductor design of larger electric current requires.
In order to achieve the above object, the utility model provides a kind of single-phase amorphous alternating current-direct current reactance device, comprise the first amorphous iron core and the second amorphous iron core that are oppositely arranged, the outside of the first amorphous iron core and the second amorphous iron core is provided with skeleton, skeleton is provided with winding outward, it is characterized in that, the first described amorphous iron core is gripped with two the first amorphous stem stems and is formed by the first amorphous iron, the second described amorphous iron core is gripped with two the second amorphous stem stems and is formed by the second amorphous iron, the first amorphous iron grip and the first amorphous stem stem between, the second amorphous iron grip and the second amorphous stem stem between, and first be all provided with air gap plate between amorphous stem stem and the second amorphous stem stem.
Preferably, described skeleton consists of upper skeleton and lower skeleton, adopts angle mutual-inserting type to connect between upper skeleton and lower skeleton.
Preferably, described winding is the winding of vertical winding forming.
Preferably, the first described amorphous iron is gripped, two the first amorphous stem stems, the second amorphous iron is gripped and two the second amorphous stem stems fix by stainless steel band.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model provides in the single-phase amorphous AC and DC of electric current 30-250A electric automobile built-in reactor, design coil is the vertical winding technologe of single enameling copper strap wire, shaping in advance winds the line coil on the vertical winding forming machine of coil, design adopts angle mutual-inserting type support framework structure again, solves the not high problem of flat mouth mutual-inserting type Skeleton assembly efficiency;
2, the utility model is enclosed within coil on skeleton, adopt each stem stem of amorphous iron core to divide three-stage structure, air gap divides six places to be evenly distributed in stem stem two legs, effectively reduce single place air gap thickness, reduce air gap loss, reduce iron core temperature rise, make reactor can meet the larger inductor design requirement of larger electric current, meeting more large power, electrically electrical automobile mileages of continuation requirement. skeleton and coil belong to the mode of being installed separately, solved the above reactor of electric current 100A because wire diameter is large, the excessive skeleton cracking phenomena that occurs of the stress that winds the line on skeleton.
The features such as 3, the vertical coiling winding appearance of reactor of the present utility model is neatly beautiful, simple for structure reliable, and heat radiation is good, and iron core temperature rise is low, maximum can realize electric current 250A reactor design, reduces volume weight reduction in the situation of identical magnetic energy product.
