Background technology
The noise main source for the vertical hydropower generator that medium waterpower generator station uses is two parts of generator and the hydraulic turbine
Part, the noise of generator are mainly made up of noise of air, electromagnetic sound and bearing noise, and generator is one more complicated
Magneto converter, electric and magnetic oscillation can be caused by higher hamonic wave in transfer process, therefore the electromagnetic noise of generator is main
Be stator harmonic field and rotor harmonic field interaction and it is caused, there is the high frequency noise of hydrogenerator the origin cause of formation to answer
The drawbacks such as miscellaneous, hidden danger is serious, is difficult to eliminate, the normal operation for not only influenceing equipment is told somebody what one's real intentions are equipment operating efficiency, but also can be given
The staff of surrounding brings the mood of agitation, influences its physical and mental health, causes greatly to threaten to hydrogenerator operation, mesh
There is the problem of correlation in preceding multiple power stations existing both at home and abroad, greatly have impact on the stable operation of unit safety, reduce
The benefit in power station, therefore above mentioned problem turns into many power stations problem urgently to be resolved hurrily.
Utility model content
In view of this, the purpose of this utility model is in view of the shortcomings of the prior art, there is provided a kind of vertical hydrogenerator
Denoising structure, noise can also be effectively reduced in the case where not influenceing stable operation of unit, the throwing in power station will not be increased again
Money, the problem of can proposing to solve the problems mentioned in the above background technology
To reach above-mentioned purpose, the utility model uses following technical scheme：
A kind of vertical hydrogenerator denoising structure of this practicality, including pole shoe, pole body, coiling group, section evidence, stator coil magnetic
Pole punching, stator core trim ring and stator core pressure refer to, and the pole shoe and pole body are overall structure, and the pole body overhead surface is set
There is the bolt for support to be fixedly mounted, the bolt is handled by strengthening hardness.
Preferably, the width of pole shoe 1 reduces 3mm, the pole shoe than the width of former pole shoe（1）Making structure be oblique pole
Structure, the angle of inclination of the pole shoe 1 is 0.682 degree.
Preferably, the coiling group coiling section saves according to for six.
Preferably, the stator core trim ring refers to stator core pressure is connected by way of welding.
Preferably, the stator core pressure refers to provided with the gradient.
The beneficial effects of the utility model are：
By changing the oblique polar angle degree of stator coil section evidence and pole shoe and referring to stator core trim ring and stator core pressure
By the acclive design structure of welded bands, the noise sent during the work of vertical hydrogenerator unit is effectively reduced, its
It can accomplish that noise can also be effectively reduced in the case where not influenceing stable operation of unit, the throwing in power station will not be increased again
Money, has ensured the physical and mental health of power station staff, has improved the use that surrounding environment also increases generator unit well
Life-span.
A kind of vertical hydrogenerator denoising structure of the utility model, including pole shoe, pole body, coiling group, section evidence, stator line
Circle pole lamination, stator core trim ring and stator core pressure refer to, and the pole shoe and pole body are overall structure, table above the pole body
Face is provided with the bolt for being used for that support to be fixedly mounted, and the bolt is handled by strengthening hardness.
Further, the width of pole shoe reduces 3mm than the width of pole shoe that original uses, and the making structure of the pole shoe is oblique
Pole structure, the angle of inclination of the pole shoe is 0.682 degree, and the pole body angle is constant.By the design structure of the program with adding
Gu support, which is combined, can effectively avoid resonance region frequency up to 800 to 1000hz, the generation rate of noise is reduced well.
Further, the coiling group coiling section saves according to for six.Although have by the design structure winding coefficient of the program
Declined, but do not interfere with the key technical indexes of motor, improved according to statistics in the fault rate of short circuit in the case of 1.1 times
The good fortune value for having brought dangerous Reeb order 4 drops to 7.8.15% by 8.364%, and more favourable reduces electromagnetic noise.
Further, the stator core trim ring refers to stator core pressure is connected by way of welding, the stator iron
Core pressure refers to provided with the gradient.The design structure of the program be used in combination with said structure will not only increase the investment in power station can also
Noise is enough effectively reduced, and does not interfere with stable operation of unit, the physical and mental health of power station staff has been ensured well, has changed
It has been apt to the service life that surrounding environment also increases generator unit.
