The utility model is to adopt following technical scheme to realize: high pressure air water cooling double-fed wind power generator, comprise electric machine casing and the rotating shaft that is positioned at its center, in rotating shaft, be provided with the iron core that is positioned at electric machine casing and the slip ring that is positioned at electric machine casing right side, electric machine casing upper end is fixed with air/water cooler, the both ends, left and right of air/water cooler bottom have the air outlet communicating with electric machine casing, the middle part of air/water cooler bottom has the air inlet communicating with electric machine casing, and the air/water cooler top inner wall between air outlet and air inlet is arc structure, in rotating shaft, be provided with the aerofoil fan that is positioned at the left and right sides unshakable in one's determination, aerofoil fan arranged outside has the air conducting cover fixing with electric machine casing, between two air conducting covers, be provided with tightly paste with left and right unshakable in one's determination both ends of the surface and with the fixing end plate of electric machine casing, on end plate, have some ventilation holes, on iron core, be arranged at intervals with the ventilation channel plate that some left and right distribute.
During machine operation, main caloric value unshakable in one's determination conducts to air/water cooler by air by motor, at air/water cooler top by the radiator that guides to of arc structure, carry out exchange heat with circulating cooling liquid, and by cooling fluid, heat is taken away, by support, the form with thermal diffusion passes another part heat; Cold air, in air outlet conducts to electric machine casing, enters aerofoil fan under the guide effect of air conducting cover, and a road enters air inlet through ventilation channel plate, and another road enters air inlet through ventilation hole, takes away the caloric value of unshakable in one's determination and winding; Iterative cycles reduces the temperature rise of motor, to guarantee the normal operation of motor, has overcome the problem that existing high-pressure blast power generator exists quick heating, poor stability.
Slip ring comprises slip ring main body, slip ring main body is connected with cooling fan on right side, cooling fan is comprised of annular hub and the blade that is fixed on annular hub outside, in annular hub, be provided with and fix with slip ring main body right side and take some to conductive pole that slip ring main body axle center is the uniform setting in the center of circle, on every pair of conductive pole, cover has T-shaped conducting block, the inner side of T-shaped conducting block has wiring hole, conductive pole inner side is provided with the encoder support being connected with slip ring main body right side, encoder support comprises two disks that be arranged in parallel and between two disks and the insulating spacer that T-shaped conducting block is separated, encoder support right circles disk center is provided with coder connecting shaft.
By assemble cooling fan, T-shaped conducting block and encoder support in slip ring main body, support the use with special-purpose slip ring room, without increasing extra cooling device, also without redesigning encoder support, in the situation that guarantee that its basic serviceability does not reduce, effectively shortened motor axial dimension, reduced motor cost, overcome slip ring and had the problem that fault point is many, assembly precision is difficult to control, operation easier is large.
The utility model reasonable in design is reliable, by ventilation and heat structure and slip ring structure are set, has effectively controlled the programming rate of motor, has improved the stability of motor; And solved the heat dissipation problem of slip ring, and reduce axial dimension, make motor realize variable speed constant frequency generator under different rotating speeds.
