Abstract
The invention discloses an insulation technology used by a wind driven generator. The outer surface of a stator coil mica tape lapping flat type copper wire (1) is coated with two layers of glass cloth reinforced dry mica tape (2) in a semi-laminated mode and then is coated with a layer of glass cloth reinforced dry mica tape (2) flatly, and a straight line part is flatly coated with insulation paper (3); the outer surface of a rotor coil copper bus (4) is coated with a polyimide film reinforced dry mica tape (5) in a semi-laminated mode and is coated with two layers of corona resistant dry mica tape (6) in a semi-laminated mode. The invention improves the ageing resistance and corrosion resistance of a wind driven generator and causes the wind driven generator to have more excellent performance, more reliable structure, more stable operation and longer service life and solves the problems of difficult wind driven generator overhauling, maintenance and the like.
Description
Technical field
The present invention relates to the insulation technology that a kind of generator uses, particularly relate to the insulation technology that uses on a kind of wind-driven generator.
Background technology
Wind energy obtains the whole world national governments and the people's attention at present as a kind of cleaning and the reproducible energy.But wind-driven generator is installed on nearly hundred meters high-altitudes of wind field, and the wind field environment is abominable as dust storm big, ultraviolet ray is strong, so just the maintenance of wind-driven generator, safeguard and become the difficult problem that wind-powered electricity generation exploitation faces.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing wind-driven generator insulation technology, the insulation technology that uses on a kind of wind-driven generator is provided at aspects such as anticorrosive and stable, useful lifes.This insulation technology is anti-aging, anticorrosive, stable, function admirable, long service life.
For realizing that the technical scheme that purpose of the present invention adopts is: the insulation technology that a kind of wind-driven generator uses, two-layer and then the flat low resin mica tape that wraps the reinforcement of one deck glass cloth at the outer first half-stack package of the wrapped flat type copper wire of stator coil mica tape, the flat bag of straight line portion insulating paper; At the low resin mica tape of the outer first half-stack package one deck polyimide film of rotor coil copper busbar reinforcement, and then the two-layer anticorona low resin mica tape of half-stack package.
Through stator and the rotor after the above-mentioned processing, the whole dipping lacquer of difference VPI (Vacuum Pressure Impregnated, vacuum pressure impregnation) behind the rule.The whole dipping lacquer of VPI makes that motor performance is better, structure is more reliable, more stable, the long service life of operation.Solve wind-driven generator and be installed on nearly hundred meters high-altitudes of wind field, be used in the different wind fields of various environmental conditions, the maintenance that is brought, maintenance problems.The used low resin mica tape of generator coil must have compatibility with insulating varnish.The key property of few adhesive tape is that gel content is few, immersing glue process Zhong Yi Seepage is saturating, it is better that impregnation is handled the back integraty, reach higher dielectric strength with thin insulation thickness, this wind-driven generator adopts with few glue cloud bar of glass cloth reinforcement with the low resin mica tape of polyimide film reinforcement, efficiently solve the turn-to-turn insulation shock problem, improved corona resisting characteristics.
Beneficial effect of the present invention is: anti-aging, the corrosion resistance that have improved wind-driven generator, make more excellent performance, the structure of wind-driven generator more reliable, more stable, the longer service life of operation, solved the difficult problems such as maintenance, maintenance of wind-driven generator.
Description of drawings
The structural representation of Fig. 1 stator coil
The structural representation of Fig. 2 rotor coil
Among the figure, 1-flat type copper wire, the low resin mica tape of 2-glass cloth reinforcement, 3-insulating paper, 4-copper busbar, the low resin mica tape of 5-polyimide film reinforcement, the anticorona low resin mica tape of 6-.
Embodiment
Further describe technical scheme of the present invention below in conjunction with accompanying drawing, as Fig. 1, the insulation technology that a kind of wind-driven generator uses, the two-layer and then flat low resin mica tape 2 that wraps the reinforcement of one deck glass cloth of first half-stack package outside the wrapped flat type copper wire 1 of stator coil mica tape, the flat bag of straight line portion insulating paper 3; As Fig. 2, the low resin mica tape 5 of first half-stack package one deck polyimide film reinforcement outside rotor coil copper busbar 4, and then the two-layer anticorona low resin mica tape 6 of half-stack package.The insulating barrier dielectric strength of this scheme is 15KV, and hot dielectric loss＜15% has effectively satisfied the insulating requirements of wind-driven generator.
