Abstract
It the utility model is related to a kind of Generator Slip Ring aeration structure, it includes generator cooler, slip ring room, slip ring room bottom is provided with exhaust outlet, it is characterized in that, further include induced duct, the slip ring room top is equipped with air inlet, and one end of induced duct is connected with the air outlet of generator cooler, and the other end of induced duct is connected with the air inlet on slip ring room top.By generator cooler tail portion, the hot-air with certain temperature after heat exchange keeps the temperature of slip ring and carbon brush stable operation in slip ring room to the utility model, slip ring temperature is unlikely to too high or too low.So that it is guaranteed that slip ring establishes good oxide-film with carbon brush mating surface, carbon brush contact is good, and abrasion is normal, prolongs the service life.The utility model further relates to a kind of generator for including above-mentioned slip ring aeration structure.
Description
Technical field
It the utility model is related to a kind of Generator Slip Ring aeration structure and generator.
Background technology
Wound-rotor type doubly-fed wind turbine realizes energy exchange using slip ring carbon brush structure, is the important set of excitation system
Into part.Generator is cooled down by special cooler, and doubly-fed wind turbine running speed is higher, slip ring and carbon brush
High-speed friction is generated heat, and since ventilation cooling structure is unreasonable, is easy to cause slip ring overheat, carbon brush abrasion is abnormal.Carbon brush and cunning
During ring normal operation, layer oxide film need to be established in slip ring surface, carbon brush is contacted with slip ring well, carbon brush abrasion is uniform, oxygen
Changing the foundation of film needs certain temperature（70 DEG C or so）, therefore it is respectively arranged with heating in existing fed wind driven generator slip ring room
Device, for preventing slip ring indoor temperature too low.To prevent slip ring overheat from also needing to install outer fan additional, cool down slip ring and brush carbon dust
And carbon dust is blown out from the air outlet of slip ring room lower part.
Application number 201510513914.2, the patent of invention of entitled " outer air blast slip ring cooling structure ", the patent of invention
A kind of outer air blast slip ring cooling structure is provided, by outside slip ring cover additional independent cooling fan cooling is aerated to slip ring,
So as to avoid slip ring from overheating scaling loss.201510513914.2 patent of invention of application number mainly passes through the additional independent anti-on-slip of wind turbine
Ring overheats；Motor manufacturing cost is increased using this patent structure mode, and add generator from power consumption, simultaneously because
External fan is added, adds a potential trouble point.
Utility model content
The purpose of this utility model is to provide lower-cost Generator Slip Ring aeration structure simple in structure and generator.
The technical solution of the utility model is that a kind of Generator Slip Ring aeration structure, it includes generator cooler, slip ring
Room, slip ring room bottom are provided with exhaust outlet, further include induced duct, and the slip ring room top is equipped with air inlet, one end of induced duct with
The air outlet of generator cooler is connected, and the other end of induced duct is connected with the air inlet on slip ring room top.
Preferably, slip ring room partition plate is further included, slip ring room partition plate is by slip ring room and bearing with end cover cell isolation.
A kind of generator of the utility model, it includes Generator Slip Ring aeration structure, the Generator Slip Ring ventilation knot
Structure is Generator Slip Ring aeration structure described above.
During work, generator, which opens the machine stage, need to open slip ring chamber heater, and lifting slip ring indoor temperature to carbon brush works temperature
Spend, after generator stable operation, close slip ring chamber heater, open cooler wind turbine, utilize generator cooler to export and draw
Wind slip ring is cooled down.
The utility model has the technical effect that, a constant temperature is carried after heat exchange by generator cooler tail portion
The hot-air of degree keeps the temperature of slip ring and carbon brush stable operation in slip ring room, slip ring temperature is unlikely to too high or too low.
So that it is guaranteed that slip ring establishes good oxide-film with carbon brush mating surface, carbon brush contact is good, and abrasion is normal, prolongs the service life.
Brief description of the drawings
Fig. 1 is the utility model embodiment structure diagram.
Embodiment
The utility model is described further below in conjunction with attached drawing.
Referring to the drawings, a kind of Generator Slip Ring aeration structure, it includes generator cooler, slip ring room 3,3 bottom of slip ring room
Portion is provided with exhaust outlet, further includes induced duct 9, and 3 top of slip ring room is equipped with air inlet, and one end of induced duct 9 and generator are cold
But the air outlet of device is connected, and the other end of induced duct 9 is connected with the air inlet on 3 top of slip ring room.
The present embodiment further includes slip ring room partition plate 7, and slip ring room partition plate 7 isolates slip ring room 3 with bearing with end cover unit 8, prevents
Blocking ash enters end cap bearing unit 8, and from generator cooler afterbody air outlet 1, slip ring is led to by wind is cooled down by induced duct 9
Room air inlet 2, into slip ring room 3, brushes surplus carbon ash, slip ring room outlet air in slip ring 6 and sliding ring brush frame carbon brush 5 and slip ring room 3
Mouth 4 is positioned at the lower section of slip ring room 3.By triggering cooler of electric motor that there is the wind of equilibrium temperature after heat exchange, slip ring room 3 is kept
Inside there is stable running temperature.
During utility model works, generator, which opens the machine stage, need to open 3 heater of slip ring room, lift temperature in slip ring room 3
To carbon brush operating temperature, after generator stable operation, 3 heater of slip ring room is closed, opens cooler wind turbine, it is cold using generator
But the wind that device outlet is drawn cools down slip ring 6.
The utility model by generator cooler tail portion after heat exchange the hot-air with certain temperature come
Slip ring 6 and the temperature of carbon brush stable operation in slip ring room 3 are kept, 6 temperature of slip ring is unlikely to too high or too low.It is so that it is guaranteed that sliding
Ring 6 establishes good oxide-film with carbon brush mating surface, and carbon brush contact is good, and abrasion is normal, prolongs the service life.
A kind of generator of the utility model, it includes Generator Slip Ring aeration structure, the Generator Slip Ring ventilation knot
Structure is Generator Slip Ring aeration structure described above.
More than be the utility model a kind of embodiment, a preferred demonstration example.Present utility model application request is protected
The scope of shield is not only limited in the embodiment.All guarantors that the utility model is belonged to the equivalent technical solution of the present embodiment
Protect scope.
