Abstract
The utility model discloses an enameled wire capable of resisting high-frequency pulses, which comprises a metal core and a polyester layer coated on the surface of the metal core. A polyamidoimide coating layer is coated on the outer surface of the polyester layer. A polyurethane layer is further coated on the outer surface of the polyamidoimide coating layer. The thickness ratio of the polyester layer, the polyamidoimide coating layer and the polyurethane layer is 1:1-1.1:0.4-0.5. The enameled wire capable of resisting high-frequency pulses has high anti-corona performances and relatively longer anti-pulse service lifetime when compared with a conventional product. The enameled wire provided in the utility model further prolongs the service lifetime of a motor and has energy-saving effects. The using demands of a variable frequency motor are further satisfied.
Description
Technical field
The utility model relates to a kind of enamelled wire of anti-high-frequency impulse, belongs to the enamelled wire technical field.
Background technology
The existing enamelled wire that is coated with polyester layer has good adhesive force, insulating properties and mechanical performance, but its anti-high-frequency impulse poor-performing, in recent years, along with developing rapidly of variable-frequency control technique, the application of variable-frequency motor is more and more extensive, especially alternating-current variable frequency motor, electricity was impulse wave when alternating-current variable frequency motor used, waveform has towering spike, and have precipitous rise time and a high frequency, the existing enamelled wire that is coated with polyester layer is used on this alternating-current variable frequency motor, and a little less than the ability of anti-high frequency and momentary pulse peak voltage, the enamelled wire winding is easy to occur the breakdown between adjacent turns phenomenon, shortened motor useful life, under these circumstances, the exploitation of the enamelled wire of the anti-high-frequency impulse that variable-frequency motor is used becomes the direction that those of ordinary skills make great efforts.
Summary of the invention
The utility model purpose provides a kind of enamelled wire of anti-high-frequency impulse, this enamelled wire has very high anti-corona performance, anti-relative existing product of pulse life-span has obtained promoting greatly, played useful life of prolonging motor and and have energy-conservation effect, satisfied the instructions for use of variable-frequency motor.
For achieving the above object, the technical solution adopted in the utility model is: a kind of enamelled wire of anti-high-frequency impulse, and comprise the metal core and be coated on its surperficial polyester layer, described polyester layer outer surface is coated with a polyamidoimide coating.
Further improved technical scheme is as follows in the technique scheme:
As preferably, described polyamidoimide coating outer surface is coated with layer of polyurethane.
As preferably, described polyester layer, polyamidoimide coating and layer of polyurethane Thickness Ratio are 1: 1～1.1: 0.4～0.5, described polyamidoimide coating in 1～1.1 during value, described layer of polyurethane any value in 0.4～0.5.
Because technique scheme is used, the utility model compared with prior art has following advantages and effect:
The enamelled wire of the anti-high-frequency impulse of the utility model, its metal core and be coated on its surperficial polyester layer, described polyester layer outer surface is coated with a polyamidoimide coating, has very high anti-corona performance, correlation test proves, the anti-pulse life-span of this enamelled wire is about 10 times of other enamelled wire, has played to prolong the useful life of motor and energy-conservation effect the fully instructions for use of variable-frequency motor; Secondly, described polyamidoimide coating outer surface is coated with layer of polyurethane, the raising to a certain degree that thermal endurance, insulating properties, machinery and the chemical-resistance of enameled wire coat integral body have been obtained.
Description of drawings
Accompanying drawing 1 is the enamelled wire structural representation of the anti-high-frequency impulse of the utility model;
Accompanying drawing 2 is A-A place cross-sectional view in the accompanying drawing 1.
In the above accompanying drawing: 1, metal core; 2, polyester layer; 3, polyamidoimide coating; 4, layer of polyurethane.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: a kind of enamelled wire of anti-high-frequency impulse, comprise metal core 1 and be coated on its surperficial polyester layer 2, described polyester layer 2 outer surfaces are coated with a polyamidoimide coating 3.
Above-mentioned polyamidoimide coating 3 outer surfaces are coated with layer of polyurethane 4.
Above-mentioned polyester layer 2, polyamidoimide coating 3 and layer of polyurethane 4 Thickness Ratios are 1: 1～1.1: 0.4～0.5, described polyamidoimide coating 3 in 1～1.1 during value, described layer of polyurethane 4 any value in 0.4～0.5.
When adopting the enamelled wire of above-mentioned anti-high-frequency impulse, its metal core 1 and be coated on its surperficial polyester layer 2, described polyester layer 2 outer surfaces are coated with a polyamidoimide coating 3, has very high anti-corona performance, correlation test proves, the anti-pulse life-span of this enamelled wire is about 10 times of other enamelled wire, has played to prolong the useful life of motor and energy-conservation effect the fully instructions for use of variable-frequency motor; Secondly, described polyamidoimide coating 3 outer surfaces are coated with layer of polyurethane 4, the raising to a certain degree that thermal endurance, insulating properties, machinery and the chemical-resistance of enameled wire coat integral body have been obtained.
Use the anti-high-frequency impulse enamelled wire of this enforcement structure, by the multiple pulses life test, the pulse life-span can reach more than 27 hours or be higher, and existing conventional enamelled wire only had about 3～4 hours.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present utility model and according to this enforcement, can not limit protection range of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed within the protection range of the present utility model.
