Abstract
The invention relates to an H-class composite protection sleeve for a winding of a motor of a refrigeration compressor, which comprises a winding sleeve and a woven layer. The woven layer is coaxially wrapped on the outer surface of the winding sleeve. The H-class composite protection sleeve is simple in structure, scientific in design, simple in manufacture and safe and reliable in use. The composite protection sleeve consists of the winding sleeve and the aramid fiber woven layer, can work in working environments of the motor of the refrigeration compressor, and can meet the H-class (180 DEG C) insulating requirement. In addition, the composite sleeve is thin and soft and is applicable to motors mounted in narrow spaces.
Description
Technical field:
The present invention relates to motor windings protective casing field, especially a kind of H level refrigeration compressor motor winding composite protective sleeve.
Background technology:
Be to guarantee the fail safe of motor, a part of motor overlaps tubing on the enamelled wire between winding and the binding post, improving the insulation property of enamelled wire, and prevents that enamelled coating because of enamelled wire from damaging and causes winding to be scrapped even motor is scrapped.
At present the sleeve pipe of suit enamelled wire is glass braid sleeve pipe and two kinds of teflon sleeves, and wherein the glass braid sleeve pipe is that glass braid and dip-coating organosilicon coating form, and this sleeve pipe can not be in the use of the workplace of refrigeration compressor motor.The cost of teflon sleeve is high, and hardness is also high, and owing to the reason of material property can't be with the wall thickness reduction of sleeve pipe, so, though use its workplace that can be used in refrigeration compressor motor, consider all improper from cost, serviceability aspect.
Summary of the invention:
The objective of the invention is to overcome the deficiency of prior art, provide a kind of reasonable in design, cost is low, tube wall approaches, be particluarly suitable for the H level refrigeration compressor motor winding composite protective sleeve that use the workplace of refrigeration compressor motor.
The objective of the invention is to realize through following technological means:
A kind of H level refrigeration compressor motor winding composite protective sleeve is characterized in that: comprise coiling sleeve pipe and braid, the coaxial outer surface that is wrapped in the coiling sleeve pipe of this braid.
And described coiling sleeve pipe is to apply the multilayer polyimide winding film of polytetrafluoroethylene and the sleeve pipe that high-temperature shaping forms with single face.
And described braid is an aramid fiber braided layer.
And described braid and coiling sleeve pipe bond together.
Advantage of the present invention and good effect are:
1, the present invention is that an inside is the coiling sleeve pipe; Composite bushing in that the cover tube outside of reeling forms with the aramid fiber braiding because the internal layer of sleeve pipe is the coiling sleeve pipe, passes through when threading easily; And the braid of outside has good pliability; Can play the effect of protection coiling sleeve pipe and enamelled wire wherein, thereby overcome the defective of single laminate roll, prolong the useful life of enamelled wire and motor around sleeve pipe or individual layer braided sleeving.
2, because the employed polytetrafluoroethylene of this composite bushing, polyimide film and aramid fiber all are the materials that is applicable to that refrigerant compressor uses; And can be for a long time 200 ℃ of work down; So sleeve pipe can bear the operational environment of refrigeration compressor motor too, can reach H (180 ℃) class F insulation requirement.
3, this composite bushing can be controlled at wall thickness below the 0.25mm, and its woven outer layer is very soft simultaneously, so whole sleeve pipe is very soft, is adapted at using in the narrow and small motor of the such installing space of refrigeration compressor motor.
4, braid of this composite bushing and coiling sleeve pipe bond together earnestly adding man-hour, thereby have effectively avoided the possibility of braid and the layering of coiling sleeve pipe, and the possibility of also having avoided braid to scatter has simultaneously guaranteed serviceability.
5, the present invention is a kind of simple in structure, design science, easy to manufacture, safe and reliable H level refrigeration compressor motor winding composite protective sleeve; This composite protective sleeve is made up of coiling sleeve pipe and aramid fiber braided layer; It can bear the operational environment of refrigeration compressor motor, can reach H (180 ℃) class F insulation requirement.In addition, this composite bushing is thin and soft, is adapted at using in the narrow and small motor of installing space.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the left view of Fig. 1.
Embodiment:
Be described in detail embodiments of the invention below in conjunction with accompanying drawing; Need to prove that present embodiment is narrative, is not determinate, can not limit protection scope of the present invention with this.
A kind of H level refrigeration compressor motor winding composite protective sleeve; Comprise coiling sleeve pipe 1 and braid 2; The coiling sleeve pipe is to form at the excellent core of certain diameter with the multilayer polyimide winding film that single face applies polytetrafluoroethylene; Through high temperature process polyimide film is bonded together behind the coiling, take out excellent core and the sleeve pipe that forms.
Braid is an aramid fiber braided layer, and the coaxial outer surface that is wrapped in the coiling sleeve pipe of braid, this braid and coiling sleeve pipe bond together earnestly adding man-hour.
