Description
Technical field
The utility model relates to enamel-cover twisted wire technical field, specifically, relates to a kind of individual layer silk bag enamel-cover twisted 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.Simultaneously, enamel-cover winds the line in use, and the insulation paint film on enamel-cover single line surface weares and teares easily, has reduced the useful life of enamelled wire.
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, efficient is low, enamel-cover twisted wire low problem in useful life, and a kind of individual layer silk bag enamel-cover twisted wire is provided.
The technical problem of the required solution of the utility model can be achieved through the following technical solutions:
A kind of individual layer silk bag enamel-cover twisted wire, described enamel-cover twisted wire be is characterized in that by at least two stranded forming of enamel-cover single line: the described enamel-cover twisted wire outside is wound with one deck dacron thread.
In the utility model, 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.
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, and the coiling direction of described dacron thread is identical with the direction of lay of enamel-cover single line.
The withstand voltage 2700-3500 volt that reaches of the utility model individual layer silk bag enamel-cover twisted wire, enamel-cover single line pinhole number is less than 1-2/6 meters, minimum resistance 0.0355 Europe/rice, the common relatively enamel-cover twisted wire of individual layer silk bag enamel-cover twisted wire heat radiation function, high frequency ability to bear are further enhanced, after individual layer silk bag 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, simultaneously, also be improved the useful life of individual layer silk bag enamel-cover twisted wire.
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 individual layer silk bag 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, individual layer silk bag enamel-cover twisted wire of the present utility model is no exception.Simultaneously, in order to increase the useful life of enamel-cover twisted wire, the utility model is wound with one deck dacron thread 2 in the enamel-cover twisted wire outside.
Stranded for the enamel-cover twisted wire, 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.
The coiling direction of the dacron thread 2 then direction of lay with the enamel-cover single line is identical, and promptly enamel-cover single line 1 is stranded clockwise, and dacron thread 2 is with regard to the clockwise direction coiling; Enamel-cover single line 1 is stranded counterclockwise, just coiling counterclockwise of dacron thread 2, and the wire rod pliability that coiling is good like this is better, and the enamel-cover single line that twists together can not be squeezed yet, and avoids producing concavo-convex.
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 2700-3500 volt that reaches, enamel-cover single line pinhole number is less than 1-2/6 meters, minimum resistance 0.0355 Europe/rice, the common relatively enamel-cover twisted wire of individual layer silk bag enamel-cover twisted wire heat radiation function, high frequency ability to bear are further enhanced, after individual layer silk bag 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, simultaneously, also be improved the useful life of individual layer silk bag enamel-cover twisted wire.
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.
