Abstract
The utility model relates to a cantilever double feed wound asynchronous wind driven generator, which comprises a motor machine base and an end cover arranged at a motor driving end, wherein the motor machine base is connected with the end cover through a ring flange; a plurality of axially extending reinforcing ribs are welded on the outer side face of the motor machine base; the end parts of the reinforcing ribs close to the motor driving end are welded with the motor ring flange; stress releasing holes are formed at positions on the reinforcing ribs where the ring flange is connected with the motor machine base; and the stress releasing holes are one-quarter circular holes. Due to the adoption of the cantilever double feed wound asynchronous wind driven generator, the technical problems of the needs of overcoming installation intensity and rigidness as well as vibration caused by the adoption of a cantilever structure existing in a conventional wind driven generator are solved, stress can be released, and the rigidness of the machine base is enhanced.
Description
Technical field
The utility model relates to a kind of cantilever wind-driven generator.
Background technology
Along with the expansion gradually at home of wind-powered electricity generation industry, wind power technology is also in continuous innovation, but because motor weight reason, need overcome the strength and stiffness of installation and therefore and the vibration that produces causes the 1.1MW wind-driven generator can't adopt cantilever structure.
The utility model content
The utility model purpose provides the Wound-rotor asynchronous wind-driven generator of a kind of cantilever double-fed, and it has solved existing wind-driven generator and has adopted cantilever structure need overcome the strength and stiffness of installation and therefore and the technical problem of the vibration that produces.
The Wound-rotor asynchronous wind-driven generator of a kind of cantilever double-fed, comprise electric machine stand 4, be arranged on the end cap 3 of motor-driven end, 3 employing ring flanges 1 of described electric machine stand 4 and end cap are connected, described electric machine stand 4 lateral surfaces are welded with a plurality of axially extended reinforcements 2, described reinforcement 2 is near the end and the welding of motor flange dish of motor-driven end
Its special character is:
Be positioned at ring flange 1 on the described reinforcement 2 and have stress relief hole 5 with the position that electric machine stand 4 joins, described stress relief hole 5 is the quadrant hole.
Advantage of the present utility model:
1, the utility model is opened the quadrant hole as stress relief hole in order to guarantee motor rigidity and control vibration with the bottom of reinforcement and ring flange junction, can reach release stress, strengthens the effect of support rigidity.
2, the utility model stress relief hole can slacken vibration.
3, the utility model stress relief hole can be with the condensation discharging of aerogenerator machine base top.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the enlarged drawing of A part among Fig. 1;
Wherein: 1-ring flange, 2-reinforcement, 3-end cap, 4-electric machine stand, 5-stress relief hole.
Embodiment
When being applied in the 1.1MW double-fed asynchronous generator, adopts the utility model air-water cooling mode, the hot-air of motor internal is via carrying out heat exchange in the support during cooling duct, the be cooled recirculated cooling water of airduct outside of heat is taken away, thereby reaches the cooling to motor internal.Cooling duct is evenly distributed on the motor inner core outside, separate with dividing plate between each pipe, as water channel, during the motor operation, cooling water circulates between the dividing plate in the airduct outside, also takes away the stator core heat of being derived by the motor inner core in the hot-air cooling to the airduct of flowing through.Electrical installation is: IBM10, when whole motor is installed on the complete machine ring flange, form a cantilever beam, therefore on electric machine stand, be welded with the reinforcement of 10mm, the quadrant hole is opened as stress relief hole in the bottom of reinforcement and ring flange junction, make globality better, increase its strength and stiffness, in motor operation course, be unlikely to produce excessive vibration, guarantee the useful life of normal operation of motor and bearing.
