The air-core reactor comprises concentric multilayer ring-shaped contraction bands (1) which are respectively arranged up and down, wherein covered windings (2) are arranged between the ring-shaped contraction bands (1); the ring-shaped contraction bands (1) are connected by radially arranged support bars (3) and form ventilating air ducts (4) between the two adjacent covered windings (2); taps of the covered windings (2) are connected with cold-pressed terminals (5); and the covered windings (2) are formed by multiple silk-covered wires or multiple stranded wires combined by enamelled wires. The air-core reactor can be widely applied in the field of reactors.
Description
Technical field
The utility model relates to a kind of air core reactor.
Background technology
At present, the reactor product that is adopted in the known active electric filter device is the copper cash air core reactor, and it is formed by multiply transposition copper cash or aluminum steel coiling.Its current density value is less, and the copper cash or the aluminum steel of consumption are more, and the product operating temperature is high, and processing technology is complicated, and cost is high.
The utility model content
The utility model technical problem to be solved is the deficiency that overcomes prior art, provides a kind of and can effectively reduce copper cash or aluminum steel consumption and reduce conductor temperature and can greatly reduce the air core reactor of production cost.
The technical scheme that the utility model adopted is: the utility model comprises respectively at the concentric multi-layer annular contraction bands that is provided with up and down; Be provided with the envelope curve winding between the said annular contraction bands that is provided with up and down; Be in and connect through the stay that radially is provided with between the said annular contraction bands of same position and between two adjacent envelope curve windings, form the ventilation air channel; The tap of said envelope curve winding is connected with cold end terminal, and said envelope curve winding is made up of multiply silk-covered wire or the stranded wire that the magnetic enamelled wire is combined into.
Said envelope curve winding is combined by copper-in-aluminum enameled wire.
Be coated with insulating paper in said every layer of envelope curve winding periphery.
Arranged outside at outer envelope curve winding has insulating barrier and surrounds whole air core reactor.
The beneficial effect of the utility model is: the utility model comprises respectively at the concentric multi-layer annular contraction bands that is provided with up and down; Be provided with the envelope curve winding between the said annular contraction bands that is provided with up and down, be in and connect through the stay that radially is provided with between the said annular contraction bands of same position and between two adjacent envelope curve windings, form the ventilation air channel, the tap of said envelope curve winding is connected with cold end terminal; Said envelope curve winding is made up of multiply silk-covered wire or the stranded wire that the magnetic enamelled wire is combined into; Because said envelope curve winding is made up of multiply silk-covered wire or the stranded wire that the magnetic enamelled wire is combined into, so the envelope curve winding is set to the magnetic enamelled wire and with the form setting of multiply silk-covered wire or stranded wire; Utilize the kelvin effect principle; Adopt little line footpath, multiply to count lead, increase the high-frequency current circulation area, when reducing the lead consumption; Reduce the temperature rise of lead effectively, greatly reduced production cost of products.

Embodiment
Like Fig. 1, Fig. 2, shown in Figure 3; In the present embodiment; The utility model comprises respectively at the concentric multi-layer annular contraction bands 1 that is provided with up and down; Be provided with envelope curve winding 2 between the said annular contraction bands 1 that is provided with up and down, be in and connect through the stay 3 that radially is provided with between the said annular contraction bands 1 of same position and between two adjacent envelope curve windings 2, form ventilation air channel 4, the tap of said envelope curve winding 2 is connected with cold end terminal 5.Said envelope curve winding 2 is made up of multiply silk-covered wire or the stranded wire that the magnetic enamelled wire is combined into.In the present embodiment, said envelope curve winding 2 is made up of the stranded wire that copper-in-aluminum enameled wire combines.Be coated with insulating paper 6 in said every layer of envelope curve winding 2 periphery.Arranged outside at outer envelope curve winding 2 has insulating barrier 7 and surrounds whole air core reactor.Said insulating barrier 7 is an epoxy plate.
Said annular contraction bands 1 is a shrink belt.Said stay 3 is the expoxy glass stay.Said insulating paper 6 is the DMD insulating paper.The utility model is with reference to the winding of copper cash air core reactor; According to the requirement of active electric filter device to the reactor parameter; Designing and calculating is specifically used specification, quantity, length and the weight of multiply silk-covered wire or twisted wire, with the multiply silk-covered wire or twisted wire is close equably is wound on the winding module frame.The line footpath of said envelope curve winding 2 is soft, and the bar number is more, and tap is removed insulating paint and selected the depainting king that can slough H class F insulation paint for use, to reach the purpose that the tap coating removal is complete, contact is good.In addition; Consider the problem of reactor winding in running medium-high frequency Effects of Noise and winding insulation intensity, mechanical strength, reactor is carried out varnished insulation oil, baking processing after, apply epoxy resin again and handle; With splicing thread pack arrangement intensity, reduce noise.
Multiply copper cover aluminum silk-covered wire or twisted wire are with reference to the winding method of multiply winding transposition wire air core reactor; According to the requirement of the number of turn that designs, the number of plies, internal diameter, height and insulation, structural strength, turn to an air core reactor that meets specification requirement; According to the line length that goes out of designing requirement, reasonably cut out tap length again, and peel off the glass fiber (to the silk-covered wire material) on the winding wire multiply silk-covered wire, (perhaps direct) pressed the cold end terminal of appropriate size again; The tap of pressing good cold end terminal is immersed in appropriate depth in the scaling powder, proposes and immersed solder line bag tap in the solder furnace that is warmed up to suitable temperature, tap line is contacted with cold end terminal well; After carrying out Preliminary detection; The semi-finished product that meet performance requirement are carried out prebake conditions handle, soak F class F insulation oil or H class F insulation oil again, drip lacquer; Baking processing applies the epoxy resin processing with oil of varnished insulation and the good reactor upper and lower end insulation of baking processing again.
In sum, the utility model can be widely used in the reactor field.
