Abstract
The invention discloses a coil-out inclined hole of a 5MW doubly-fed wind generator rotor shaft. The coil-out inclined hole comprises an coil-out inclined hole body, wherein the coil-out inclined hole body and a horizontal direction can form a 40-degree angle, the length of the coil-out inclined hole body on the rotor shaft is increased, the coil-out inclined hole body internally adopts a circular bead polishing manner, and the number of rotor wires is increased to six. The coil-out inclined hole provided by the invention has the advantages that the coil-out inclined hole body with the 40-degree angle is adopted, so that the rotor wires are convenient to insert; meanwhile, the bending angles of the rotor wires are reduced, and the reliability of the rotor wires is increased; the distance of the inclined hole body in the rotor shaft is increased, the stress is dispersed, and the mechanical strength of the shaft is increased.
Description
Technical field
The present invention relates to a kind of novel rotor shaft outlet inclined hole, particularly a kind of inclined hole outlet of 5MW double-fed wind power generator rotor axle.
Background technique
In recent years, wind-power electricity generation shared ratio in the first annual amount of world's energy improves gradually.International wind-powered electricity generation is devoted for years to boundary in improving wind powered generator system Security, reliability, generating efficiency and developing more large-scale wind driven generator and super sized type coastal waters Special wind generator, adopt novel set structure and control mode and material, improve wind energy turbine set addressing and designing technique, can economic utilization wind energy resources amount constantly to reduce cost of wind power generation and to expand.
Along with economic development, increasing to energy demand, power supply shortage sustainable existence, wind-driven generator, as new energy resource power machine tool, is the developing direction of low-carbon energy-saving new technology.Double-fed wind power generator rotor is Wound-rotor type structure, three-phase winding leading-out wire is generally drawn with slip ring and is connected from the axis hole of rotor shaft end by elastic cable paper, and axis hole is by rotor axial blind hole and open on rotor shaft cylndrical surface and the inclined hole communicating with rotor axial blind hole forms.Current original small-power double-fed wind power generator rotor rotating shaft inclined hole outlet adopts three wire outlet holes, and when wind-driven generator power ascension, rotor shaft intensity can die down.Threephase cable lighting outlet is the mobile vitals of bidirectional energy between frequency variator and rotor; Therefore, its reliability design in axis hole is directly connected to the reliable operation of wind power generating set.
Summary of the invention
In order to guarantee that wind power generating set safely and steadily runs, the invention provides a kind of outlet inclined hole of 5MW double-fed wind power generator rotor axle.
Technological scheme of the present invention is specific as follows:
The outlet inclined hole of 5MW double-fed wind power generator rotor axle, comprising: outlet inclined hole; Described outlet inclined hole, from the horizontal by 40 ° of angles, increases the length of outlet inclined hole on rotor shaft, adopt fillet polishing mode, and increase rotor wire is the six roots of sensation in outlet inclined hole.
Beneficial effect of the present invention is:
(1) take the outlet inclined hole at 40 ° of angles; Facilitate rotor wire to insert, reduce rotor wire bend angle simultaneously, increased the reliability of rotor wire; Increased outlet inclined hole at rotor shaft middle distance, dispersive stress, thus increased the mechanical strength of axle;
(2) edge of outlet inclined hole adopts manual grinding fillet, increases the area of contact of rotor shaft and rotor wire, reduces pressure, has also reduced the wearing and tearing of rotor shaft to rotor wire, increases the reliability of rotor wire;
(3) in 5MW double-fed wind power generator, adopting rotor wire is six roots of sensation outlet, has reduced the aperture of outlet inclined hole when reducing electric density, and the stress on rotor shaft is disperseed more, increases the mechanical strength of axle, increases the reliability of axle.
The present invention has not only chosen suitable outlet angle, facilitates outlet, but also has guaranteed that processing technology is easy, easily realizes, and has guaranteed on this basis the mechanical strength of rotor shaft.

The present invention has accompanying drawing 1 width.
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is further described:
The outlet inclined hole of 5MW double-fed wind power generator rotor axle, comprising: outlet inclined hole; Described outlet inclined hole is from the horizontal by 40 ° of angles, reduce to insert the difficulty of rotor wire, increase the length of outlet inclined hole on rotor shaft, reduce stress and concentrate, increase the mechanical strength of rotor shaft, thereby increased the Security of motor operation, in outlet inclined hole, adopted fillet polishing mode, reduced the wear damage of the corner angle of outlet inclined hole to wire, and increase rotor wire is the six roots of sensation, stress on rotor shaft is disperseed more, increase the mechanical strength of axle, increase the reliability of axle.
Claims (1)
- The outlet inclined hole of 1.5MW double-fed wind power generator rotor axle, is characterized in that comprising: outlet inclined hole; Described outlet inclined hole, from the horizontal by 40 ° of angles, increases the length of outlet inclined hole on rotor shaft, adopt fillet polishing mode, and increase rotor wire is the six roots of sensation in outlet inclined hole.
