The insulating structure for a collecting ring and an electric brush device in a wind-driven generator of the utility model is adapted to outdoor harsh conditions of wind, rain, ice snow and thunder, and particularly can bear corona under high voltage.
Description
Technical field
The utility model relates to a kind of insulation system, especially a kind of insulation system that is used for wind-driven generator collector ring and brushgear.
Background technology
The wind energy cleaning is renewable.Wind power generation is promoted rapidly in China.Promote the manufacturing of wind-driven generator, thereby needed to adapt to collector ring, the brushgear of harsh working condition.The core technology of collector ring, brushgear is insulation.Collector ring, brushgear are the main parts size of wind-driven generator.Wind-driven generator is loaded on the high frame about 60m.Standing the erosion of wind, rain, ice and snow, thunder and lightning.Working condition is harsh.Maintaining inconvenience.The function of collector ring in wind-driven generator is that rotor (armature) circuit and external circuit (power transmission network) are coupled together.Its reliability concerns the safe operation of wind-driven generator.And the reliability of collector ring, brushgear is good and bad inseparable with its insulation system.Present collector ring, the insulating material of brushgear are gone up substantially and are all used phenolic composition, perhaps use epoxy glass cloth laminated board, with this class material as collector ring insulation system material, the harsh working condition that can not adapt to open-air wind, rain, ice and snow, thunder and lightning, especially can not bear the corona under the condition of high voltage, thereby the necessity of improving the collector ring insulation system is arranged.
Collector ring is a rotating parts, and along with wind speed, wind direction change, height when hanging down during the collector ring rotating speed is also just followed and changeed, reverses, and this just requires collector ring to have higher mechanical strength and structure is loosening.And the wind-driven generator collector ring is in open-air harsh working condition again, therefore requires the collector ring insulation system to have: the dielectric property that (1) is high; (2) leakage current is little; (3) anti-corona under the high voltage condition; (4) high temperature resistant, anti-high and cold; (5) enough mechanical strengths are arranged.
The utility model content
(1) technical problem that will solve
Technical problem to be solved in the utility model provides a kind of insulation system that is used for wind-driven generator collector ring and brushgear at the existing in prior technology defective, can adapt to the harsh working condition of open-air wind, rain, ice and snow, thunder and lightning, especially can bear the corona under the condition of high voltage.
(2) technical scheme
The technical scheme that its technical problem that solves the utility model adopts is: a kind of insulation system that is used for wind-driven generator collector ring and brushgear, and collector ring and brushgear mainly are made up of axle sleeve, conducting ring and lead-out wire thereof, brush holder support, fishplate bar, insulating barrier; All be surrounded by insulating barrier at axle sleeve, lead-out wire, brush holder support external diameter.
Described insulating barrier is divided into inside and outside two-layer, is respectively mica powder belt and gob layer of cloth.
Described mica powder belt and gob layer of cloth impregnated insulating paint.
The insulating barrier that thickness 4mm is arranged between described conducting ring and the axle sleeve; The insulating barrier of brush holder support external diameter bag thickness 4mm.
(3) a kind of insulation system that is used for wind-driven generator collector ring and brushgear of the present utility model compared with prior art has following beneficial effect:
A kind of insulation system that is used for wind-driven generator collector ring and brushgear of the utility model is the innovation of insulation against ground, phase insulation.At first be the innovation of material selection, select the thermal endurance class height for use, the mica paper tape 5440 of high voltage withstanding, anti-corona as main insulation, is selected the intensity height for use, good insulation preformance, resistant to elevated temperatures 3640 glass grey cloths are as supporting material.Mica paper tape is the essential insulating material of generator high-tension coil.Dielectric strength 〉=35KV/mm, anti-corona, tensile strength 〉=100Mpa; 3640 glass cloth are epoxy phenolic glass cloth tube materials, manufactured goods tensile strength 〉=80Mpa, and dielectric strength, insulation resistance is also very high.Can adapt to the harsh working condition of open-air wind, rain, ice and snow, thunder and lightning, especially can bear the corona under the condition of high voltage.
