Abstract
An insulating structure used on a wind generator is disclosed, comprising an electromagnetic wire rod, the electromagnetic wire rod is wrapped with a self-adhesive polyimide film wrapped with glue powder mica tapes bonded integrally via an insulating soakage resin, and the glue powder mica tapes of the electromagnetic wire rod is wrapped with surface insulating enamel, thus a complex insulating structure is formed. The surface insulating enamel may be sprayed or coated out of the glue powder mica tapes. The insulating structure, which is applied to the wind generator with addition of a layer of self-adhesive polyimide film and the surface insulating enamel having strong salt spray resistance thereon, can meet the demands of mechanical intensity, salt spray resistance, moisture resistance and cold/hot resistance of the wind generator under execrable operating ambience.
Description
Technical field
The utility model relates to a kind of insulating material and structure, relates to a kind of insulating material that uses on wind-driven generator and structure specifically.Be mainly used in wind-driven generator as insulation system.
Background technology
Wind energy more and more is subjected to the attention of countries in the world as a kind of regenerative resource of cleaning.But wind power generation plant generally all under rugged environment (as: dust storm is big, ultraviolet ray is strong, marine climate) carry out work, this operational environment is very serious to the corrosion of wind power generation plant.To be electromagnetic wire constitute with being wrapped on the described electromagnetic wire and by the dry mica paper tape that insulating impregnating varnish is bonded as one the insulation system of making wind-driven generator in the prior art.The salt fog resistance and the weatherability of this structure are relatively poor, the insulation system premature aging, and insulation resistance descends.Therefore necessary this is improved.
The utility model content
The purpose of this utility model is the deficiency at the insulation system that uses on the existing wind-driven generator, the insulation system that uses on a kind of novel wind generator is provided, this kind wind-driven generator insulation system can improve the salt spray resistance and the weather resistance of insulation system, thereby improves the service life of insulation system.
According to the purpose of this utility model, the technology implementation scheme that is put forward is: the insulation system on a kind of wind-driven generator, comprise the electromagnetic wire rod, the self-adhering-type polyimide film has been wrapped on described electromagnetic wire rod, and be wrapped with the dry mica paper tape that is bonded as one by insulated impregnating resin at the self-adhering-type polyimide film, be wrapped with surface insulation enamel paint at electromagnetic wire rod dry mica paper tape again, formed a kind of composite insulation structure.Surface insulation enamel paint can be spraying or brush outside dry mica paper tape.This insulation system increases the surface insulation enamel paint of one deck tack polyimide film and the strong salt fog resistance of surface spraying, be applied on the wind-driven generator, can satisfy mechanical strength, salt spray resistance, the humidity cold-resistant heat request of wind-driven generator under abominable running environment.
This insulation system is strengthened intercoil insulation resistance, salt fog resistance and moisture resistance greatly, has guaranteed the dielectric strength of coil.Mainly contain following characteristics:
1, coil insulation intensity has obtained reliable assurance;
2, the salt fog resistance of coil and weatherability are improved;
3, technology is simple, workable.
Description of drawings
Fig. 1 is a three-dimensional structure diagram of the present utility model;
Fig. 2 is structure master's cutaway view of the present utility model;
Fig. 3 is the A-A direction cutaway view of Fig. 2.
Wherein: 1, electromagnetic wire rod; 2, self-adhering-type polyimide film; 3, dry mica paper tape; 4, surface insulation enamel paint.
Embodiment
Accompanying drawing has provided embodiment of the present utility model, from accompanying drawing as can be seen, the utility model is the insulation system on a kind of wind-driven generator, comprise electromagnetic wire rod 1, self-adhering-type polyimide film 2 has been wrapped on described electromagnetic wire rod 1, and be wrapped with the dry mica paper tape 3 that is bonded as one by insulated impregnating resin at self-adhering-type polyimide film 2, and outside electromagnetic wire rod dry mica paper tape 3, be coated with surface insulation enamel paint 4 again, form a kind of composite insulation structure.This insulation system increases the surface insulation enamel paint of one deck tack polyimide film and the strong salt fog resistance of surface spraying, can improve mechanical strength, salt spray resistance, the humidity cold-resistant hot property of wind-driven generator under abominable running environment.
