Abstract
The utility model relates to a slip ring for a wind power generator, which belongs to the technical field of manufacturing of a wind power generator component. The slip ring is composed of a shaft sleeve, a grounded ring connected at the end part of the shaft sleeve, a fixed disc, a small encoder shaft, a phase conducting rod, an insulating disc, a fixed screw rod arranged between the grounded ring and the fixed disc, phase rings arranged on the fixed screw rod, and a separation piece arranged among the phase rings, the fixed disc and the grounded ring. The slip ring is characterized in that: a gap is respectively arranged between an inner ring of each phase ring and the shaft sleeve; the separation piece among the phase rings, the fixed disc and the grounded ring is modified electric porcelain; and a gap is arranged between the outer rim of the modified electric porcelain and the shaft sleeve. With the advantages of good radiating property and good hydrophobic property, the slip ring is especially suitable for the high-power wind power generator.
Description
Technical field
The utility model relates to a kind of slip ring of wind-driven generator.Belong to wind-driven generator parts manufacture technology field.
Background technology
The slip ring that is used for wind-driven generator at present by axle sleeve, the ground loop that is connected sleeve end, fixed disk, the little axle of encoder, phase conducting rod, insulating disc, be installed in standing screw between ground loop and the fixed disk, be installed in and encircle mutually and be located at mutually that the distance piece between ring and fixed disk, the ground loop constitutes on the standing screw, the distance piece that encircles inner ring and each phase interannular mutually of slip ring all is close to installation with axle sleeve.The shortcoming of this slip ring is a poor radiation, is unwell to high-power wind-driven generator and uses.In addition, the used spacer surface hydrophobicity of each phase interannular is poor, slip ring under the more moistening air ambient in operation process with carbon brush move mutually the carbon dust that produces easily attached to spacer surface on, reduce the insulation resistance of distance piece, easily produce electrical breakdown, cause equipment breakdown.
The utility model content
For overcoming the shortcoming of slip ring poor radiation, the utility model provides a kind of slip ring of perfect heat-dissipating for wind-driven generator.
This slip ring by axle sleeve, the ground loop that is connected sleeve end, fixed disk, the little axle of encoder, phase conducting rod, insulating disc, be installed in standing screw between ground loop and the fixed disk, be installed in and encircle mutually and be located at mutually that the distance piece between ring and fixed disk, the ground loop constitutes on the standing screw, it is characterized in that having a gap between described each inner ring that encircles mutually and the axle sleeve, at the distance piece between ring and fixed disk, the ground loop mutually is the modification electroceramics, has a gap between the outer rim of modification electroceramics and the axle sleeve.
This slip ring adopts fabricated construction, between each inner ring and axle sleeve that encircles mutually, all hold certain space length between the cylindrical of each distance piece outer rim and axle sleeve to guarantee that air can free flow, thereby can make things convenient for the heat that produces when in time slip ring being worked to take away, use to satisfy high-power wind-driven generator.
As a same reason, can offer the end face through hole on ring, fixed disk, ground loop, the insulating disc mutually, these end face through holes help to form the circulation passage of air, make things convenient for air to take away the heat of slip ring.
The utility model compared with prior art has the following advantages:
1, the temperature rise of slip ring is little, can make the more stable work of motor, is beneficial to the expansion of the slip ring scope of application, especially under harsh conditions, such as using in the wind-driven generator of installing in the very high place of surface temperature.Be particularly suitable for high-power wind-driven generator.
2., be difficult for to improve effectively the generator operation time, reduce downtime and reach interference electrical network attached on the electroceramics with carbon ash after the moving carbon brush wearing and tearing that contacts of slip ring.
Provide embodiment below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Embodiment
Referring to Fig. 1, this slip ring by the little axle 11 of axle sleeve 4, the ground loop 1 that is connected axle sleeve 4 ends, fixed disk 7, encoder, phase conducting rod 10, insulating disc 9, be installed in standing screw 8 between ground loop 1 and the fixed disk 7, be installed in and encircle 3,5,6 and be located at mutually that the distance piece 2 between ring and fixed disk, the ground loop constitutes mutually on the standing screw 8, more than each parts all continue to use prior art.This slip ring be characterised in that described each have a gap 12 between inner ring of ring and the axle sleeve mutually, be the modification electroceramics at the distance piece between ring and fixed disk, the ground loop mutually 2, have a gap 13 between the outer rim of modification electroceramics and the axle sleeve.
Can also screwed hole 14 be set at the close cylindrical place of fixed disk 7 and ground loop 1, adjust mass distribution when making things convenient for slip ring to do dynamic balancing.
Claims (2)
1. the slip ring of a wind-driven generator, by axle sleeve, the ground loop that is connected sleeve end, fixed disk, the little axle of encoder, phase conducting rod, insulating disc, be installed in standing screw between ground loop and the fixed disk, be installed in and encircle mutually and be located at mutually that the distance piece between ring and fixed disk, the ground loop constitutes on the standing screw, it is characterized in that having a gap between described each inner ring that encircles mutually and the axle sleeve, at the distance piece between ring and fixed disk, the ground loop mutually is the modification electroceramics, has a gap between the outer rim of modification electroceramics and the axle sleeve.
2. the slip ring of wind-driven generator as claimed in claim 1 is characterized in that being provided with screwed hole at the close cylindrical place of described fixed disk and ground loop.
