Abstract
The utility model relates to a lead wire for an H-grade fluoride-resistant motor. The lead wire consists of a metal conductor, an inner braid ply, a wrapping layer and an outer braid ply; and the inner braid ply and the outer braid ply are woven by polyester fibers. The lead wire is characterized in that the using material of the wrapping layer is polyimide film of which the thickness is 0.020 to 0.030mm. The lead wire has the advantages of simple structure, low cost and high heat resistant grade, and is the lead wire dedicatedly designed for the H-grade fluoride-resistant motor.
Description
Technical field
The utility model relates to a kind of cable in the electromechanical equipment, especially a kind of H level motor lead of anti-the fluorine.
Background technology
Motor is a kind of visual plant in the electromechanical equipment, and it provides power for other electromechanical equipment, has played the part of the key player in industrial automated process.It is the limiting temperature division that allows by the used insulating material of motor that the class of insulation of motor is divided, several grades such as Y, A, E, B, F, H, C are arranged, tolerance limit temperature at different levels is respectively 90,105,120,130,155,180 ℃, reaches more than 180 ℃, limiting temperature is meant the permission maximum operating temperature of motor insulation material, the heat resistance of its reaction insulating material.Lead wire is the connecting line that is used to connect motor windings and casing binding post, heat-resisting requirement according to each grade motor, the limiting temperature of the insulating material of employed cable should reach the limiting temperature of the corresponding motor class of insulation, and the structure of the common cable of anti-the fluorine is: be followed successively by metallic conductor from inside to outside, the interior braid that is made into by the polyster fibre material, the lapping layer of making by polytetrafluoroethylene film, the lapping layer of making by polyester film, the outer braid that is made into by the polyster fibre material, the greatest limit temperature that the cable of assembling by said structure generally reaches is 120～130 ℃, and the cable that this structure is formed can't be used for H level motor.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, with low cost, thermal endurance class height, the H level motor lead of anti-fluorine of saving production cost.
The technical scheme that the utility model is taked is:
A kind of H level motor lead of anti-the fluorine is made up of metallic conductor, interior braid, lapping layer and outer braid, and described interior braid and outer braid are made into by polyster fibre, it is characterized in that: the material that described lapping layer uses is a polyimide film.
And the thickness of described polyimide film is 0.020～0.030 millimeter.
Advantage of the present utility model and good effect are:
1. the lapping layer of this lead wire uses polyimide film material, this material is a kind of high temperature resistant organic polymer thin film, be by pyromellitic acid anhydride (PMDA) and diaminodiphenyl ether (ODA) in extremely strong property solvent dimethylacetylamide (DMAC) through polycondensation and hydrostomia film forming, forming through imidization again. it is the present best film class insulating material of performance in the world, has excellent mechanical property, electrical property, chemical stability and very high radiation resistance, and its limiting temperature is-269 ℃ to+400 ℃, temperature span is very big, is applicable to that each common grade motor uses.
2. the polyimide film material of the lapping layer of this lead wire use adopts processing method commonly used to make, and manufacturer does not need more exchange device, has reduced the processing cost of manufacturer.
3. the utility model is simple in structure, with low cost, the thermal endurance class height, and its insulation thickness is thin, has reduced the volume of cable, and radiating effect has been strengthened in the space of having improved each equipment room after installing in electromechanical equipment, has improved service life of equipment.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of cable in the prior art.
Embodiment
Below in conjunction with embodiment, the utility model is further specified, following embodiment is illustrative, is not determinate, can not limit protection range of the present utility model with following embodiment.
A kind of H level motor lead of anti-the fluorine as shown in Figure 1, is made up of metallic conductor 1, interior braid 2, lapping layer 3 and outer braid 4, and interior braid and outer braid are polyster fibre and are made into, and the material that lapping layer uses is a polyimide film.O.020～0.030 millimeter the thickness of polyimide film is, the film thickness in the present embodiment is 0.025 millimeter.
Compare (as Fig. 2) with the existing common construction of cable, the lapping layer 6 that has replaced original lapping layer of making by polytetrafluoroethylene film 5, made by polyester film by the lapping layer of polyimide film coiled in the utility model, not only reduced the thickness of lapping layer, and its temperature range limit is also very big, has reached-269 ℃ to+400 ℃.Cable behind the employing polyimide film internal layer has reduced the aging speed of cable inner insulating layer under hot conditions, the useful life and the scope of application of cable have been improved, and reducing owing to layer thickness in the polyimide film, it is very little that the diameter of cable and volume also become, and increased the heat-dissipating space between each equipment in the electromechanical equipment system.
Claims (2)
1, a kind of H level motor lead of anti-the fluorine is made up of metallic conductor, interior braid, lapping layer and outer braid, and described interior braid and outer braid are made into by polyster fibre, it is characterized in that: the material that described lapping layer uses is a polyimide film.
2, the H level motor lead of anti-fluorine the according to claim 1, it is characterized in that: the thickness of described polyimide film is 0.020～0.030 millimeter.
