Abstract
In order to solve the problems of the existing enameled stranded-wire of low voltage resistance, large resistance, poor heat dissipation efficacy, low high-frequency bearing capability as well as low inductance Q value and low efficiency after the existing enameled stranded-wire is wound into an inductance coil, the utility model provides an enamelled stranded-wire containing a self-fluxing polyurethane enammelled round copper wire. The enamelled stranded-wire is formed by stranding at least two enamelled single wires. Each enamelled single wire comprises a round copper wire and an insulating paint film on the surface of the round copper wire. The insulating paint film is made of self-fluxing polyurethane paint. The voltage resistance of the enamelled stranded-wire containing the self-fluxing polyurethane enammelled round copper wire can reach 1,700V to 2,500V, and the pinhole number of each enamelled single wire is less than 1 to 2 pieces per 6m, and the minimum resistance is 0.0355 ohm/m. The stranded enamelled stranded-wire has the characteristics of good heat dissipation efficacy, strong high-frequency bearing capability and the like. The enamelled stranded-wire is wound into the inductance coil, so that the inductance Q value and the efficiency of the coiler are obviously improved, and the demand of various high-end application occasions is fully met.
Description
Technical field
The utility model relates to enamel-cover twisted wire technical field, specifically, relates to a kind of enamel-cover twisted wire that comprises straight weldering based polyurethane enamel insulated round copper wire.
Background technology
Common enamel-cover twisted wire is by stranded the forming of enamel-cover single line more than two, compare it with the enamel-cover single line and improved surface area, and Distribution of Magnetic Field is more even, kelvin effect is little, and the high frequency equivalent resistance is lower, and eddy current is little, temperature rise is low, transmission characteristic is good, and anti-corona ability and high frequency voltage bearing capacity are stronger, therefore applies to the making of winding, coil in common electric machine, transformer, electrical equipment, the instrument widely.
But that general enamel-cover twisted wire is withstand voltage is low, resistance big, heat radiation function is poor, the high frequency ability to bear is low, behind the coiled inductance coil, inductance Q value is low, and efficient is low, is difficult to satisfy the user demand such as products such as electromagnetic stove, microwave oven, special transformer, high-speed induction motors.
The utility model content
The utility model be big at withstand voltage low, the resistance of existing enamel-cover twisted wire, heat radiation function is poor, the high frequency ability to bear is low, behind the coiled inductance coil, inductance Q value is low, inefficient problem provides a kind of enamel-cover twisted wire that comprises straight weldering based polyurethane enamel insulated round copper wire.
The technical problem of the required solution of the utility model can be achieved through the following technical solutions:
A kind of enamel-cover twisted wire that comprises straight weldering based polyurethane enamel insulated round copper wire, described enamel-cover twisted wire is by at least two stranded forming of enamel-cover single line, it is characterized in that: described enamel-cover single line is made of the insulation paint film on circular copper wire and circular copper wire surface, and described insulation paint film adopts straight weldering based polyurethane lacquer.
In the utility model, the thickness of described insulation paint film is the 3%-10% of circular copper wire diameter, and film thickness reduces with the increase of circular copper wire diameter.
According to the actual needs, described at least two enamel-cover single lines adopt clockwise direction stranded or counterclockwise stranded.
The utility model comprises the withstand voltage 1700-2500 of the reaching volt of the enamel-cover twisted wire of straight weldering based polyurethane enamel insulated round copper wire, enamel-cover single line pinhole number is less than 1-2/6 meters, minimum resistance 0.0355 Europe/rice, stranded good enamel-cover twisted wire has characteristics such as heat radiation function is good, the high frequency ability to bear is strong, after the enamel-cover twisted wire turns to inductance coil again, make the inductance Q value and the efficient of coil all be significantly improved, can satisfy the demand of a lot of high-end use occasions fully.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is the cross section structure schematic diagram of the utility model enamel-cover twisted wire.
Fig. 2 is the cross section structure schematic diagram of the utility model enamel-cover single line.
Embodiment
In order to make technological means of the present utility model, creation characteristic, to reach purpose and effect is easy to understand,, further set forth the utility model below in conjunction with concrete diagram.
Referring to Fig. 1, for any enamel-cover twisted wire, its all by at least two enamel-cover single lines 1 around being twisted into, the enamel-cover twisted wire that comprises straight weldering based polyurethane enamel insulated round copper wire of the present utility model is no exception, according to actual needs, enamel-cover single line 1 of the present utility model can adopt clockwise direction (S to) stranded, also can adopt counterclockwise (Z to) stranded, because no matter adopt the sort of mode stranded, cross section structure all is identical.Those skilled in the art's strand mode is also known, and is not repeated herein.
Referring to Fig. 2, enamel-cover single line 1 of the present utility model is made of the insulation paint film 12 on circular copper wire 11 and circular copper wire 11 surfaces, insulation paint film 12 adopts straight weldering based polyurethane lacquer, this is because straight weldering based polyurethane paint film has tough, gloss is plentiful, strong adhesion, characteristics such as water proof and wearable, corrosion resistance can satisfy the user demand as required coil on the products such as electromagnetic stove, microwave oven, special transformer, high-speed induction motor.
Straight weldering based polyurethane film thickness can not be too little, otherwise can reduce withstand voltage, increase the pinhole number of enamel-cover single line 1 unit length, therefore, the thickness of straight weldering based polyurethane varnished insulation paint film 12 is the 3%-10% of circular copper wire 11 diameters in the utility model, and film thickness reduces with the increase of circular copper wire 11 diameters.Like this, promptly satisfied withstand voltage and the requirement unit length pinhole number, can not increase production cost again, and the external diameter after making the enamel-cover twisted wire finish can be not excessive because film thickness is bigger than normal.
By above-mentioned setting, the withstand voltage 1700-2500 volt that reaches of enamel-cover twisted wire of the present utility model, enamel-cover single line 1 pinhole number is less than 1-2/6 meters, stranded good enamel-cover twisted wire has characteristics such as heat radiation function is good, the high frequency ability to bear is strong, after the enamel-cover twisted wire turns to inductance coil again, make the inductance Q value and the efficient of coil all be significantly improved, can satisfy the demand of a lot of high-end use occasions fully.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
