Description
Technical field
The utility model relates to generator and manufactures field, especially a kind of collector ring of generator cooling sound arrester.
Background technology
Collector ring of generator is alloy steel forging, and its surf zone is the most concentrated position of heat, if too concentrate in running and can not distribute in time, collector ring temperature will be caused constantly to rise, eventually exceed limiting temperature, collector ring cannot normally be used, the consequence of damaging property time serious.Harbin Electric Machinery Plant 600MW generator configuration Sound Proof Brush Holder structure, collector ring cooling air adopts " under enter under go out " mode, namely be arranged in the platen of bottom into and out of air duct, air outlet and air inlet are positioned at generator platform lower floor top and vicinity, because hot blast accumulates in top, the hot blast of air outlet blowout is again inhaled into air inlet and goes to cool collector ring, make cooling air temperature rise, and carry a large amount of carbon dust, blocking collector ring louvre, vicious circle like this, causes collector ring temperature to raise, and threatens the safe operation of turbo generator.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, provides one can effectively reduce cooling air temperature, decreases collector ring region carbon powder content, ensures the cooling sound arrester of collector ring of generator stability and safety work.
For solving the problems of the technologies described above, the basic conception of the utility model employing technical scheme is:
A kind of collector ring of generator cooling sound arrester, comprise armature spindle, be arranged on the collector ring on armature spindle, the centrifugal fan be disposed adjacent with collector ring, the carbon brush contacted with collector ring, connect the carbon brush supports of carbon brush, cover centrifugal fan and be provided with the fan housing of inlet and outlet, described fan housing air inlet is coaxially disposed adjacent with collector ring, also comprise and cover above-mentioned collector ring, the blimp of carbon brush and fan housing, it is characterized in that: described blimp offers air inlet and air outlet, described air outlet is arranged higher than collector ring horizontal level, described fan housing outlet upwards arranges and is connected with described air outlet.
Also comprise an operating room be connected with described blimp, described operating room covers described armature spindle, described operating room is offered and is equipped with operating room air inlet.

Armature spindle 1, carbon brush supports 2, collector ring 3, carbon brush 4, centrifugal fan 5, fan housing 6, blimp 7, air inlet 8, air outlet 9, goes out blast cap 10, filter screen 11, platen 12, air inlet duct 13, exhaust passage 14, operating room 15, operating room air inlet 16.
Embodiment
If Fig. 1 is collector ring of generator cooling sound arrester in prior art, as seen from the figure prior art blimp 7 does not arrange inlet and outlet, but below platen, be provided with turnover air channel, fan housing 6 exports to arrange downwards and is connected with the exhaust passage 14 below platen 12.Hot-air is discharged blimp 7 (figure represented by dotted arrows hot-air) from fan housing outlet by high pressure during operation in fan housing 6 downward through exhaust passage 14, simultaneously because the air inlet duct 13 of cool exterior air below platen is sucked blimp (realizing in figure representing cold air) by the suction function of centrifugal fan, thus achieve the circulation of air inside and outside blimp.
But this design has a lot of defect, such as, shown in Fig. 2, air inlet duct 13 and exhaust passage 14 are disposed adjacent, the phenomenon that the hot blast that air outlet easily occurs at inlet and outlet place is sucked by air inlet, and are sucked by the carbon dust of air outlet simultaneously.Which results in the rising making cooling wind-warm syndrome, electric ring region carbon powder content raises simultaneously, easily blocking collector ring louvre, and vicious circle, causes collector ring temperature to raise, there is hidden trouble, threatens the safe operation of turbo generator.Simultaneously owing to having air inlet duct and exhaust passage, increase the path of air-flow operation, turning and reducing, thus add windage.
For solving the problems referred to above in prior art, the utility model devises a kind of collector ring of generator cooling sound arrester.
A kind of collector ring of generator cooling of the utility model sound arrester as shown in Figure 3, comprise armature spindle 1, be arranged on the collector ring 3 on armature spindle, the centrifugal fan 5 be disposed adjacent with collector ring 3, the carbon brush 4 touched with current collection articulating 3, connect the carbon brush supports 2 of carbon brush 4, cover centrifugal fan 5 and be provided with the fan housing 6 of inlet and outlet, described fan housing 6 air inlet is coaxially disposed adjacent with collector ring, also comprise and cover above-mentioned collector ring 3, the blimp 7 of carbon brush 4 and fan housing 6, it is characterized in that: described blimp 7 offers air inlet 8 and air outlet 9, described air outlet 9 is arranged higher than collector ring horizontal level, described fan housing 6 exports and upwards arranges and be connected with described air outlet 9.
The feature that this kind is arranged is the fan housing 6 arranged in prior art outlet to change into downwards upwards to arrange, its advantage is, make use of the principle that hot-air rises, hot-air is discharged by the ascendant trend by hot-air itself, discharge hot-air also the carbon dust that carbon brush comes off to be discharged in the lump smoothly simultaneously, and the principle of similar chimney, adds the negative pressure in blimp 6, is conducive to the suction of cold air.
A kind of collector ring of generator cooling of the utility model sound arrester, also comprise an operating room 15 be connected with described blimp, described operating room 15 covers described armature spindle 1, described operating room 15 is offered and is equipped with operating room air inlet 16.
The object arranging this operating room 15 is, part armature spindle can being exposed blimp is also covered, and is conducive to strengthening soundproof effect further, is covered by armature spindle simultaneously and also ensure that production safety.On operating room 15, offer operating room air inlet 16 simultaneously, make blimp 7 can get wind from operating room 15 side, more enhance soundproof effect.Therefore preferably also comprising an operating room 15 be connected with described blimp, described operating room 15 covers described armature spindle 1, and the scheme being equipped with operating room air inlet 16 offered by described operating room 15.
A kind of collector ring of generator cooling of the utility model sound arrester, described air outlet 9 is arranged on the top of described blimp 7.
Air outlet 9 is arranged on higher than playing the effect utilizing hot-air ascendant trend to help hot gas discharge during collector ring horizontal level.But when air outlet 9 is arranged on blimp 7 top, air outlet 9 position is the highest, and effect is better, and therefore preferred described air outlet 9 is arranged on the technical scheme at the top of described blimp 7.
A kind of collector ring of generator cooling of the utility model sound arrester, described air intake 8 mouthfuls is arranged on blimp 6 side.
