Description
Technical field
The present invention relates to slip ring chamber structure of electric motor, specially fed wind driven generator slip ring cell structure.
Background technology
Double-fed wind power generator in the process of running, the friction of slip ring and carbon brush in slip ring room, can cause slip ring and carbon brush
Temperature steeply rise, can cause to shut down when reaching temperature trip limit value, it is therefore necessary to try every possible means to slip ring, carbon brush cooling.
Secondly carbon dust caused by both frictions, which is assembled, is attached to slip ring surface, causes slip ring ring fire even couple corrosion, causes slip ring surface
It is uneven, it is therefore necessary to handle carbon dust collection in time.Prior art（As shown in Figure 1）To be reserved at the top of slip ring room
Have air inlet, be provided with into air duct, from generator hollow cooler introduce wind regime, double-fed wind power generator in the process of running,
By the way of drying from the top down, slip ring is flowed through, brush holder is cooled, and infundibulate air-out is installed in slip ring room bottom
Caused carbon dust, is collected by cylinder in chimney fan bottom.
Above-mentioned prior art has the disadvantage that：Wind regime is introduced using from hollow cooler first, due to absolutely empty
Cooler air outlet wind regime has been the later wind regime of motor heat exchange, and self-temperature is higher, is dropped again to slip ring, carbon brush with it
Temperature, it is difficult to reach preferable effect, furthermore because part air quantity does not flow through slip ring, brush holder, utilization rate is low, it is difficult to reaches low-temperature-rise
Effect.Secondly by the way of drying from the top down, during carbon dust is discharged into bottom chimney fan, due to one on brush holder, brush box
A little stops of the annex to wind path, cause carbon dust to be adhered to slip ring room peripheral part, cause secondary pollution, and it is even more difficult to safeguard
To accomplish to clean comprehensively.
The content of the invention
The present invention solves the prior art cooling of fed wind driven generator slip ring room and row's carbon dust effect is undesirable
A kind of problem, there is provided new fed wind driven generator slip ring cell structure.
The present invention adopts the following technical scheme that realization：Fed wind driven generator slip ring cell structure, including slip ring room master
Body, insulation wind deflector one, insulation wind deflector two, insulation wind deflector three, insulation wind deflector four, spiral case of the bottom with powder outlet are prevented
Shield and centrifugal fan；Air inlet is provided with slip ring room main body side plate；Insulation wind deflector one is installed on slip ring room main body bottom plate
On, for preventing air quantity from directly passing through from slip ring bottom；Insulation wind deflector two is circular slab, and its center is provided with via, via wheel
Exterior feature is formed by connecting by small arc-shaped and orthodrome, and the radius of small arc-shaped ensures that slip ring stretches out insulation wind deflector two, the arc length of small arc-shaped
Whole carbon brush can be streaked, insulation wind deflector two is installed between the adpting flange plate and spiral case protective cover of slip ring room main body one end,
Small arc-shaped in the same side and makes the arc length of small arc-shaped streak whole carbon brush with the air inlet on slip ring room main body side plate during installation,
For preventing air quantity to be directly entered centrifugal fan；Insulation wind deflector three is installed on the slip ring room main body side plate above air inlet,
Insulation wind deflector four is installed in slip ring room top body plate, and spiral case protective cover surrounding is fixed on the connection method of slip ring room main body one end
On blue plate；Centrifugal fan is located in spiral case protective cover and is fixed on slip ring or in rotating shaft（Centrifugal fan is fixed on slip ring
On can reduce the axial length of double-fed wind power generator）.
The fed wind driven generator slip ring cell structure using install when, make carbon brush brush holder system be installed on slip ring room just on
Side, is on the one hand easy to carbon brush to change, on the other hand on wind path；The effect of insulation wind deflector one is to prevent air quantity directly from cunning
Ring bottom is passed through, and is not passed through carbon brush brush holder；The effect of insulation wind deflector two is to prevent air quantity to be directly entered centrifugal fan, only surplus
Sub-fraction passes through the brush rocker and carbon brush of surface；The effect of insulation wind deflector three and the wind deflector four that insulate is located at wind path flowing through channel
On, play wind-guiding；Carbon dust collecting protective cover uses spiral case type of design, improves fan efficiency, and carbon dust enters spiral case protective cover,
In bottom collection processing.In motor operation, centrifugal fan rotates with axle, produces suction；Outside wind regime is through air inlet
After, due to the effect for the wind deflector one, two, three, four that insulate so that air quantity largely flows through brush holder, brush box, flowing through channel
For：Air inlet --- insulation wind deflector three --- brush holder, brush box --- insulation wind deflector four --- insulation wind deflector two（Orthodrome
Gap between slip ring）--- centrifugal fan --- spiral case protective cover, the purpose to slip ring, carbon brush cooling is played, simultaneously
Exhausting takes away caused carbon dust, is collected in spiral case bottom.
Fed wind driven generator slip ring cell structure of the present invention uses sidepiece air intake, and wind deflector is used inside slip ring room
Wind-guiding wind path is formed, cooling air largely flows through slip ring carbon brush, reaches the effect of slip ring room low-temperature-rise；Using with slip ring room master
The spiral case protective cover of body isolation is collected to carbon dust, is avoided causing secondary pollution to slip ring room peripheral part, is reached cleaning mesh
, reduce the workload of attendant.
