Abstract
The asynchronous generator consists of the chassis, the formed stator winding, the stator iron core and the rotator. Special points are that the chassis possesses a water cooling twin layers; the wind tube is buried within this twin layers; two sets of twin formed stator windings with different pole numbers are adopted; A centrifugal fan is set on the rotator. The end of the formed winding is colligated with a soft end hoop. The two windings are separated by a discontinuous colligation with the double soft end hoops. The axis directional vent holes are made on the rotator core. The invention ensures a stable, safe, reliable and efficient running. Its power can reach 1300/ 250 KW.
Description
Technical field
The present invention relates to a kind of generator, be specially powerful asynchronous wind driven generator with duplex winding in dual speeds.
Background technology
At present, main force's type necessary electromotor of 600kW and 750kW wind turbine generator is a double winding air cooling asynchronous generator.For improving the wind turbine generator designing and manufacturing level, catch up with the development trend of large-scale unit, with MW level double speed double winding wind turbine generator as one of main force's type of Stall Type wind-force unit.The MW level wind asynchronous-generator that the structure of existing general asynchronous generator is not suitable for the present invention relates to, be in particular in: general double speed double winding wind-driven generator adopts air-cooled cooling structure, epitrochanterian internal fan, external fan produce bigger wind abrasion, have reduced electric efficiency.Winding adopts the embedding winding that looses, and damages the conductive line surfaces insulation in the process of rule easily, causes motor turn-to-turn and phase insulation weak link easily, and the motor feels hot, to such an extent as to insulation breakdown influences normal operation of motor and generating.At present, the above double speed double winding of MW level wind-driven generator adopts air-cooled structure, and the motor cooling effect is bad, and volume is big, is not suitable for the little requirement of Stall Type wind turbine generator moment of inertia.
Summary of the invention
The part-structure that the present invention is directed to general double speed double winding wind-driven generator is not suitable for the deficiency that the above wind asynchronous-generator of MW level exists on cooling structure and insulation system, a kind of high-power double speed double winding wind asynchronous-generator of novel simple structure is provided.
The objective of the invention is by realizing with following technical scheme: it comprises casing, the moulding stator winding, stator core, rotor, casing is made the water cooling interlayer, and embedding in the casing interlayer ventilation duct arranged, employing two is socketed into two moulding stator winding of different numbers of poles, one centrifugal fan is installed on the rotor, the hot blast that produces on the rotor is pressed into the cold wind that carries out in the water jacket ventilation duct after the heat exchange from anti-drive end, in the time of the cooling stator winding end, axially enter rotor and enter motor internal from drive end, so circulation constitutes motor internal ventilation wind path and water-cooling structure.
The invention has the beneficial effects as follows: for high-power double speed double winding wind asynchronous-generator provides reasonable and practical structural design, casing water-cooling structure and two moulding winding construction have been provided, make the operation of this high-power double speed double winding wind asynchronous-generator more stable, safe and reliable, the efficient height, power can reach 1300/250Kw.
Description of drawings
Fig. 1 is the overall structure schematic diagram of one embodiment of the invention.
Among the figure: 1, casing, 2. moulding stator winding, 3, stator core, 4, rotor, 5, ventilation duct, 6, centrifugal fan, 7, the colligation of soft end hoop, 8, two soft end hoop, 9, ventilation hole.
Embodiment
The present invention is further described below in conjunction with drawings and Examples.
With reference to Fig. 1, present embodiment comprises casing 1, moulding stator winding 2, stator core 3, rotor 4, and casing 1 is made the water cooling interlayer, and embedding in casing 1 interlayer ventilation duct 5 is arranged, employing two is socketed into two moulding stator winding 2 of different numbers of poles, and a centrifugal fan 6 is installed on the rotor.Adopt two soft end hoops 8 to be interrupted colligation between the end of moulding winding 2 soft end hoop colligation 7, two windings and separate, have axial ventilation hole 9 in the rotor core 3.Centrifugal fan 6 is pressed into the cold wind that carries out in the water jacket ventilation duct after the heat exchange with the hot blast that produces on the rotor from anti-drive end, in the time of the cooling stator winding end, axially enter rotor and enter motor internal from drive end, so circulation constitutes motor internal ventilation wind path and water-cooling structure.
Moulding winding 2 adopts the high-strength magnetic line of reinforced insulation, end soft end hoop colligation, two windings adopt electrical apparatus insulation and machinery to emphasize high composite material to separate, and to the infringement of winding insulation, have guaranteed generator reliable and stable operation when running up when guaranteeing behind rule integer.
