Abstract
The utility model discloses a conductive shaft applied to a 3.0 MW high-power wind power slip ring. The conductive shaft applied to the 3.0 MW high-power wind power slip ring comprises a lay plate, a shaft body, a lower pressure plate, a plurality of ring pieces, a plurality of insulating spacers, an upper pressure plate and a bearing seat. The insulating spacers are arranged between every two adjacent ring pieces. An insulation paste is primed by vacuum on an outer side wall of the shaft body. The conductive shaft applied to the 3.0 MW high-power wind power slip ring is characterized in that the diameter of the insulating spacers is larger than the diameter of the ring pieces by 0.3-0.7 mm, and grooves are processed on outer side walls of the insulating spacers. According to the utility model, through the protrusion height of the insulating spacers and the design of the grooves, the electric arc phenomena between adjacent ring pieces are solved, the insulating resistance and the dielectric strength of the conductive shaft are improved, the insulating resistance can reach 1000 M Omega/DC/500 V, the dielectric strength can reach 2000 V/AC/50 Hz, the structure rigidity of the conductive shaft is improved, the service reliability and the service life of the wind power slip ring are improved, the service life of the wind power slip ring applied with the conductive shaft of the utility model can reach 100 million revolutions, and the operating requirement of the high-power wind power slip ring assembly of 3.0 MW and above is satisfied.
Description
Technical field
The utility model relates to wind power equipment, especially relates to a kind of conductive shaft of the 3.0MW of being applied to high-power wind turbine slip ring.
Background technology
Conductive shaft is one of core component of wind-powered electricity generation slip ring assembly; The rigidity of the insulation resistance of conductive shaft, dielectric strength and axis body directly has influence on the relevant art index height of whole wind electric slip ring assembly, thereby influences the dependability and the stability of whole wind electric slip ring assembly.
At present; Traditional conductive shaft mainly is made up of axis body, some ring plates and some insulation spacers; Between adjacent two ring plates, be provided with insulation spacer; It is lower that it is applied in the wind-powered electricity generation slip ring assembly dielectric strength and insulation resistance, can not satisfy the relevant art requirement of 3.0MW and above high-power wind turbine slip ring.Especially when the electric energy transmitting of 3.0MW and above high-power wind turbine slip ring; Because the diameter of insulation spacer equals the diameter of ring plate; The insulation effect of insulation spacer is undesirable; Thereby be prone between the ring plate of conductive shaft, arc phenomenon take place, and then damage wind-powered electricity generation slip ring assembly, the dependability and the life-span of having reduced the wind-powered electricity generation slip ring assembly.
Summary of the invention
The purpose of the utility model is to provide a kind of conductive shaft of the 3.0MW of being applied to high-power wind turbine slip ring; This conductive shaft has not only solved the arc phenomenon between the adjacent ring plate; The insulation resistance and the dielectric strength of conductive shaft have been improved; And improved the structural rigidity of conductive shaft and the dependability of wind-powered electricity generation slip ring assembly and life-span.
The purpose of the utility model is achieved in that
A kind of conductive shaft that is applied to 3.0MW high-power wind turbine slip ring; Form by distributor plate, axis body, lower platen, some ring plates, some insulation spacers, top board and bearing pedestals; On the lateral wall at axis body middle part, be with lower platen, some ring plates, some insulation spacers and top board from left to right successively; Between adjacent two ring plates, be provided with insulation spacer; The lead-in wire of some ring plates passes from the cable-through hole of distributor plate respectively; Priming by vacuum has lower platen, some ring plates, the some blocks of insulating cements that insulation spacer, top board seal on the lateral wall of axis body, and characteristic is: the diameter of insulation spacer is processed with groove than the big 0.3～0.7mm of diameter of ring plate on the lateral wall of insulation spacer.
The width of the groove of insulation spacer is 0.2mm, and the degree of depth is 0.1mm.
The utility model since on the basis of the conductive shaft of routine through strengthening the diameter of insulation spacer, and on the lateral wall of insulation spacer, be processed with groove, the width of groove is 0.2mm; The degree of depth is 0.1mm; I.e. projecting height and groove design through insulation spacer, not only prevented between adjacent ring plate the electric arc effect, solved the arc phenomenon between the adjacent ring plate, improved the insulation resistance and the dielectric strength of conductive shaft; Insulation resistance can reach 1000M Ω/DC/500V; Dielectric strength can reach 2000V/AC/50Hz, and has improved the structural rigidity of conductive shaft, and the dependability of wind-powered electricity generation slip ring assembly and life-span; The wind-powered electricity generation slip ring assembly life-span of using the utility model can reach 100,000,000 commentaries on classics, has satisfied the instructions for use of 3.0MW and above high-power wind turbine slip ring assembly.
