FIELD: power industry.

SUBSTANCE: rotor of segmental wind-driven electric generator includes rim, disc, hub and rotor elements. Rotor elements are made in the form of plates which are connected in the form of an angle and fixed on disc.

EFFECT: reducing the weight and dimensions of rotor of wind-driven electric generator at minimisation of its cost due to simplifying the manufacturing technology; providing high manufacturability and possibility of both classic design, and design in the form of magnetic flux modulator for inductor generator.

 

The invention relates to the field of wind energy, in particular wind power segment type.

Known rotors of wind power generators are the traditional type that contains the hub, blades and cores, in the more General case of curved elements can be closed (as the USSR №732572 / Vchalichob and other - wind farm. BI No. 17, 1980, F03D 3/30).

Also known direct-drive wind turbines, the rotor is made in the form of arcuate elements, and the stator is in the form of segmental blocks, which in General increases the weight and dimensions as the USSR №861716 / Ispropyl and other - Direct-drive wind turbines. BI No. 11, 1981, F03D 1/00).

Of all known analogues closest to the claimed combination of essential features is the rotor of wind power, which is part of microelectroporation installation and includes a permanent magnet mounted in the middle of the "C"-shaped bracket with a bandage of a non-magnetic wire and the rim, disk and hub (RF patent No. 2211951 / A.m.litvinenko - Microelectrochemistry installation. Publ. BI No. 25 dated 10.09.2003, application No. 20011359 46/06 from 27.12.2001, MKI F03D 9/00).

The disadvantage of this rotor is that it cannot be used with induction generator and the complexity of attachment associated with the use of remagnino what about the band, increased weight.

The invention is directed to reducing the weight and size of the rotor of the wind power while minimizing its cost by simplifying the manufacturing technology.

The achievement of the technical result due to the fact that the rotor of the wind power segment type, containing rim, disc, wheel hub and rotor elements, according to the invention the rotary elements in the form of plates, which are connected in the form of an angle and attached to the disk.

The invention is illustrated by drawings, where figure 1 shows the rotor with the stator in section, a side view, figure 2 is a view of the stator with the rotor front rotor in the active version in figure 3 - rotor in the passive execution.

The rotor is part of wind power segment performance, which contains the tower 1, the rotary base 2, head 3, on which is fixed a stator magnetic circuit 4, through which the air gap 5 is in magnetic contact rotor, having in its composition plates 6 and 7 connected in the corner of the stud 8. In the active variant is the source of the magnetic field of the permanent magnet 9. This stud 8 angular rotor element mounted on the ledge of the rim 10. The rim 10 is attached on the disk 11. To the disk by means of the mounting ring 12 attached to the blades 13 of the propeller. The hub 14 of the rotor strengthened in the head 3 by means of bearings is of nikov 15 and 16. The head is also provided with a tail beam 17 with a tail plane (not shown in figure 1, so as not to clutter the drawing). The stator in this embodiment is equipped with a coil 18. In the induction case, the source of the magnetic field is absent, and the rotor is formed of two plates 6 and 7, fastened by a pin 8. In this embodiment, shown in figure 3, the source of the magnetic field is located on the stator, one of the plates of the stator is a coil 19.

The operation of the device. In the presence of the wind flow, which exerts pressure on the blade 13, the rotor starts to rotate. Ferromagnetic cores 7 and 6 (in fact, the rotor teeth) modulate the magnetic flux of the stator. The stator is mounted on the lower end of the head 3, which is attached to a movable (rotatable) base 2, which also strengthened the cylinder 3 and the tail beam 17 of wind power. The stator, like all stators induction generators constitute a magnetic circuit, in which, in addition to the magnetic circuit, including a source of magnetic field is a permanent magnet or coil excitation, and the working coil 19, which senses changes in flow caused by its modulation by the rotor. The induced voltage is then fed to the control unit and then to the load. In the classic version, shown in figure 1 and figure 2, between the plates 6 and 7 of the rotor to set the len magnet 9, in this case, the plates of the stator is connected directly to the corner stud, with one or two of them covered by the coils.

Feasibility advantage of this rotor is its high adaptability, due to the use of a strip of magnetic circuits, as well as the possibility of classical performance and execution in the form of a modulator of the magnetic flux for induction generator.

The rotor of the wind power segment type, containing rim, disc, wheel hub and rotor elements, characterized in that the rotary elements in the form of plates, which are connected in the form of an angle and attached to the disc.
