The heavy-current increductor is characterized in that the inductive winding 1 is formed by the way that a plurality of windings with same winding and turn number as well as identical direction are overlapped on the framework through the successive layer and one-layer-one-winding way, each winding is flat wound on the framework 4 or the wound winding by the way that a single strand or a plurality of strands of lacquered wires with suitable diameter just meet the needed turn number of the increductor, leading-out wires 5 of the head end and the tail end of each winding are respectively connected in parallel together, and the magnetic core 3 is arranged in the hole of the framework 4. The winging method of the increductor is simple, the contact among the turns of the lead in the winding is tight and the leakage inductance is very little, and the heat transmission is better. One single winding is flat wound and is hardly repeated and overlapped without the contact of striding several turns and the head end close to the tail end, the distributed capacitance is very low, and the overall characteristic of the increductor is better. The heavy current increductor can be widely applied to occasions of the transformer needing to feed to an electric network such as switching mode power supplies, filtration of inverters, active power factor correction, wind power generation, and the like.
Description
Affiliated technical field
The utility model relates to a kind of inductor in high frequency, requires under the high-frequency high-voltage occasion especially that distributed capacitance is low, leakage inductance is little, density is high and conduct heat good high-current inductor.Be mainly used in high frequency switch power, Active Power Factor Correction, UPS or generatings such as inverter filtering, wind-force or solar energy and be fed to current transformer of electrical network etc.
Background technology
At present, known big electric current inductor in high frequency is for reducing kelvin effect, the general enamelled wire that all adopts strands on the magnetic core skeleton back and forth from level to level coiling repeatedly form, for high voltage inductors, at the insulation film isolated insulation that every interlayer also must be better with dielectric strength, heatproof is higher, also must keep certain electric clearance and creepage spacing or necessary insulating spacer at every layer of winding end face, to guarantee that each interlayer can not produce arcing or arcing under the high voltage.But the insulation measures of stranded wire and interlayer, end face not only makes winding construction loose, the electric conductor duty ratio descends, unavoidable produce bigger leakage inductance and be unfavorable for that the conduction of heat distributes, and winding repeatedly coiling back and forth, also there is bigger distributed capacitance between winding layers between contact-making surface.These leakage inductances and distributed capacitance all can the grievous injury high-frequency inductor performance and parameter.
Summary of the invention
In order to overcome existing inductor in high frequency leakage inductance big, conduct heat difference and the big deficiency of distributed capacitance, the utility model provides a kind of inductor in high frequency, and this inductor not only coiling is convenient, and leakage inductance is little, distributed capacitance is low and density is high, conduct heat.
The technical scheme that its technical problem that solves the utility model adopts is: the stranded and multilayer structure of coiling repeatedly back and forth of multiply enamelled wire originally, make into sub-thread or multiply enamelled wire only in individual layer folk prescription to flat around, promptly when design, select the enamelled wire diameter according to the winding length and the number of turn, making in the length that single layer winding allows can just be around the required number of turn down, and then with each single layer winding superposition one by one on skeleton and be connected in parallel.Not only technology is simple for this technical scheme, enamelled wire flat around compact structure, folk prescription to not back and forth repeatedly coiling can realize that winding leakage inductance minimum and distributed capacitance are minimum, and every layer of every turn-to-turn contact between the lead current potential very near or approximate equipotential, need other insulation measures hardly, density and heat-transfer character that this just greatly reduces the technology insulating requirements and has improved the line bag.Thereby realized that coiling is convenient, leakage inductance is little, distributed capacitance is low and density is high, the good purpose of conducting heat.
The beneficial effects of the utility model are: the inductor high frequency characteristics is good, technology is simple, reliability is high.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is a structural profile schematic diagram of the present utility model, and its code name is represented respectively: 1. enamelled wire winding, 2. insulation film between winding layers, 3. inductor core, 4. winding skeleton, 5. winding lead-out wire.
Embodiment
In the accompanying drawings, winding 1 is flat on skeleton 4 with the enamelled wire layering: every layer according to winding length and need around number of turn choose reasonable enamelled wire diameter, make flat can just reach the required number of turn around one deck; Pad uses the same method behind the thin film 2 again, the same number of turn and the direction coiling second layer, the 3rd layer So in layer flat around be arranged on the skeleton 4, have how many layers what windings are promptly arranged, till the sectional area of individual layer enamelled wire multiply by the number of plies and satisfies the required lead gross area of inductance.Being lined with film 2 at every interlayer is that the surface is all more smooth during for every layer of coiling; Because the number of turn and the coiling direction of every layer of each winding are in full accord, the electromotive force of being responded to during their work also is identical, so potential difference can be greater than the magnitude of voltage of 1 circle between the enamelled wire of each locational enamelled wire and levels, only depend on the insulation of enameled wire coat all enough like this, make the insulating requirements of interlayer film 2 drop to minimum; Just because of induced potential is equal fully, after the drawing separately end to end of every layer of each winding, just can simply be connected in parallel in the inductor outside, as go between 5, the total current of inductor is all assigned to each layer winding during work, can bear very big electric current, and its effect is equal to twisted wire; Line bag after the coiling inserts magnetic core 3 and has just constituted described inductor in high frequency with relevant technology.
" specification digest accompanying drawing " is identical with " Figure of description ".
