Description
Technical field
The utility model belongs to lead, relates to the electromagnetic wire that electric coil windings such as motor, generator, transformer are used.
Background technology
At present, high-tension motor, wind energy (power) generator, water energy (power) generator, gas energy generator, the electromagnetic wire that coil windings adopted of power transmission and transformation line transformer has following several: adopt the polyimide film band or be equipped with adhesive, insulating varnish again, the electromagnetic wire of anaerobic glass fiber (cloth) wrapped (insulation) (claiming the imines line on the market); With mica (powder, paper) and polyester film composite band or be equipped with adhesive, insulating varnish, the electromagnetic wire (claiming the mica line on the market) that anaerobic glass fiber (cloth) is wrapped; Be with wrapped sintering line with polyimide film sintered, perhaps be equipped with adhesive again, anaerobic glass fiber (cloth) lapping electromagnetic wire (claiming the imines sintering line on the market); The electromagnetic wire (claiming paper covered wire on the market) that paper is wrapped.
More than the problem that exists of all kinds of electromagnetic wires:
1. imines line heatproof is stronger than mica line, but withstand voltage properties is poorer than the mica line, and anti-corona performance is also poor than the mica line.
2. mica line proof voltage, anti-corona are all strong than imines line, but heat resistance differs about about two times than imines line, because it is the mica tape that mica (paper, powder) and polyester film are composited that the mica line is produced employed twining package tape, though mica is resistant to elevated temperatures material, but after it and polyester film are compound, when temperature reaches about 120 when spending, polyester film meeting strain cracking, cause being compounded in the mica (paper on the polyester film, powder) also distortion simultaneously, cracking causes the performance of coil windings puncture short or the anti-corona of its proof voltage to descend significantly.
Existing electromagnetic wire is because of the problems referred to above, and the instructions for use when making it can not satisfy the equipment operation operating mode and with environment bigger variation takes place is unfavorable for saving energy and reduce the cost, and can not adapt to the requirement of economic development and scientific and technological progress.
The utility model content
The purpose of this utility model is to provide a kind of electromagnetic wire and coil windings that has heatproof and voltage endurance simultaneously.
The purpose of this utility model is realized by following technical scheme:
Electromagnetic wire of the present utility model comprises the bare copper flat wire core, be surrounded with the compound inslation band on the bare copper flat wire core, described compound inslation band is composited by one deck polyimide film and one deck mica (paper, powder), also one deck mica (paper, powder) can be compounded in centre, also available simultaneously multilayer polyimide film and alternate being composited of mica (paper, powder) of two strata imide membranes.This kind electromagnetic wire is called the FY recombination line.
In the production process with described compound inslation band lapping electromagnetic wire, but also coordinated insulation coats with lacquer, the anaerobic glass fiber, and adhesive uses together, forms to add layer on the compound inslation band of coiling, to strengthen the protective capability on electromagnetic wire adhesive force and surface.
Another kind of electromagnetic wire of the present utility model comprises the bare copper flat wire core, sintering has the polyimide sintered film band on the bare copper flat wire core, be surrounded with the compound inslation band on the polyimide sintered film band, described compound inslation band is composited by one deck polyimide film and one deck mica (paper, powder).In production process with described compound inslation band lapping electromagnetic wire, also can cooperate anaerobic glass fiber, insulating varnish and adhesive to use together, between wrapped compound inslation band, form and add layer, to strengthen the protective capability on electromagnetic wire adhesive force and surface.This kind electromagnetic wire is called FS mica sintering line.
Coil windings of the present utility model is formed by above-mentioned electromagnetic wire (comprising FY recombination line and FS mica sintering line) coiling.
The characteristics of electromagnetic wire of the present utility model are that the compound inslation band adopts the insulating material with different premium properties to be composited, and combines their advantage, makes it have heatproof and performance withstand voltage, anti-corona simultaneously.That is: the composite band of polyimide film and mica (paper, powder) replaces the mica tape (polyester film and mica (paper, powder) are compound) that existing market is used.Show (shown in subordinate list) through tens of result of the tests, the mica tape that uses on insulated compound band of the present utility model and the market is compared, and heatproof is three times of mica tape, and proof voltage is the twice of mica tape, tensile strength high approximately 30%.More crucial the more important thing is, original insulation thickness standard 70cmm can be reduced to 40cmm ~ 45cmm, (insulation thickness of this insulated compound girdle tests data is that 45cmm, mica tape then are 70cmm), if equal insulation thickness, the insulation of composite band, heatproof, anti-corona performance also can be higher.
Subordinate list
| Puncture voltage (effective value) | Temperature tolerance | Insulation thickness | |
| Mica line on the open market | 6000-7000V | <155℃(120℃) | 70cmm |
| The FY recombination line | 12000-13000V | >260℃(340℃) | 45cmm |
For example, one 10,000 volts motor 90 grooves, one groove (circle) coil is around 30 circles, one circle attenuate 25cmm, 30 circles, one groove attenuate insulation thickness 750cmm (promptly 7.5 millimeters), but 675 millimeters of 90 groove attenuate insulation thicknesses press motor manufacturing technology, electromagnetic scheme calculating, it is about about 30% that the motor of equal model specification can improve power, otherwise can reduce the material cost more than 20%.At present, 10,000 volts of voltage motors that China's motor manufacturing is produced can only be produced on the support of height of center 450mm, had the electromagnetic wire (FY recombination line) of the wrapped production of insulated compound band of the present utility model just can make 10,000 volts of motor fully on the support of 400mm, this will be the breakthrough technological progress of motor manufacturing.The coil windings of wind energy (power), water energy (power), gas energy generator, if use FY recombination line or FS mica sintering line, its efficient, benefit, quality all have the lifting than Datong District's degree.
The utility model is described in further detail below in conjunction with accompanying drawing.
