Abstract
The utility model discloses a slip ring cooling system, comprising a cooling device and a wind guiding device, one end of the wind guiding device is communicated with the cooling device, and the other end is communicated with the slip ring. When cooling of the slip ring is performed, the wind guiding device is used to blow wind generated by the cooling device to the slip ring, thereby taking effect of cooling the slip ring, and eliminating carbon powder. The slip ring cooling system is advantageous in that, since wind of a wind outlet of the cooling device is directly used to perform cooling, compared with a cooling mode of an external cooling blower fan or an internal centrifugal blower fan, since rotary parts of the external cooling blower fan or the internal centrifugal blower fan and a rotary shaft are reduced, the slip ring cooling system is characterized by low cost and high motor efficiency.
Description
Technical field
The utility model relates to technical field of wind power generation, particularly a kind of slip ring cooling device.
Background technology
Double-fed wind generating is a kind of Wound-rotor type induction generator, is the core component of speed-variable frequency-constant wind-driven generator group, is also one of critical component of wind turbine generator production domesticization, in the production domesticization ratio of whole wind turbine generator in occupation of very important status.
Slip ring is the important composition parts of double-fed wind power generator.Slip ring is cooling is an importance of slip ring.The cooling commonplace cooler mode of slip ring is at present: built-in centrifugal fan is cooling or external cooling fan is cooling.But the rotating parts that has increased in cooling blower and rotating shaft due to external cooling fan and the built-in centrifugal fan type of cooling is many, causes cooling cost to improve, and also causes the Efficiency Decreasing of motor simultaneously.
Therefore, how solving the problem that cooling cost is high and electric efficiency is low, is those skilled in the art's technical issues that need to address.
The utility model content
The purpose of this utility model is to provide a kind of slip ring cooling system, can reduce cooling cost, improves simultaneously electric efficiency.
For addressing the above problem, the utility model provides a kind of slip ring cooling system, comprises cooler and air ducting, and an end of described air ducting is communicated with described cooler, and the other end is communicated with described slip ring.
Preferably, described air ducting comprises wind scooper and ventilating duct, and described wind scooper is communicated with described cooler and described ventilating duct respectively, and described ventilating duct is communicated with described slip ring.
Preferably, the material of described ventilating duct is for being bellows or steel.
Preferably, described ventilating duct is communicated with described wind scooper by bolt.
With respect to the above-mentioned background technology, slip ring cooling system provided by the utility model comprises cooler and the air ducting that is communicated with cooler and slip ring respectively.When cooling to slip ring, utilize air ducting that the cold wind that cooler produces is blowed to slip ring, slip ring is carried out cooling down.This slip ring cooling system, due to the wind of the air outlet that has directly utilized cooler carry out cooling, with respect to the type of cooling of external cooling fan and built-in centrifugal fan, due to the rotating parts that reduces in external cooling fan or centrifugal fan and rotating shaft, has cost low, the electric efficiency high.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only embodiment of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to the accompanying drawing that provides other accompanying drawing.
Fig. 1 is the structural representation of slip ring cooling system provided by the utility model.
In Fig. 1:
The 1-cooler, 2-ventilating duct, 3-slip ring, 4-wind scooper.
Embodiment
Core of the present utility model is to provide a kind of slip ring cooling system, can reduce cooling cost, improves simultaneously electric efficiency.
In order to make those skilled in the art person understand better the utility model scheme, below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
Please refer to Fig. 1, Fig. 1 is the structural representation of slip ring cooling system provided by the utility model.
Slip ring cooling system provided by the utility model comprises cooler 1 and air ducting, and the two ends of air ducting are connected with the air-guiding hole that the air outlet of cooler 1 is connected with slip ring respectively.The cold wind that cooler 1 produces enters in slip ring 3 by air ducting, and slip ring 3 is cooled.
With respect to prior art, the utility model has the advantages that: when cooling to slip ring, utilize wind that air ducting produces cooler to slip ring, slip ring is not only played cooling effect, also play the function of getting rid of carbon dust.This kind slip ring cooling system, because the wind of the air outlet that has directly utilized cooler carries out cooling, the type of cooling with respect to external cooling fan or built-in centrifugal fan, due to the rotating parts that reduces in external cooling fan or built-in centrifugal fan and rotating shaft, has cost low, the characteristics that electric efficiency is high.
In a kind of embodiment, air ducting comprises ventilating duct 2 and wind scooper 4, and an end of wind scooper 4 is arranged on the air outlet place of cooler 1, is communicated with the air outlet of cooler 1 is airtight, and the other end is communicated with the air-guiding hole of ventilating duct 2 is airtight.The opposite end of an end that is connected with wind scooper 4 of ventilating duct 2 is communicated with slip ring 3.
So arrange, simple in structure, process easy for installationly, further reduce the cooling cost of cooling slip ring 3.
The barrel of ventilating duct 2 can be the bellows barrel, also can be the barrel of other materials such as steel.The plasticity of bellows is strong, easily regulates; The durability of steel is strong.
The shape of ventilating duct 2 can be for square, circular etc., determines according to the shape of the air-guiding hole of slip ring 4.
As other execution mode, ventilating duct 2 also can use the mode of riveted joint or welding to be connected with the lower part outlet of wind scooper 4 and the air-guiding hole of slip ring 3.
Above slip ring cooling system provided by the utility model is described in detail.Used specific case herein principle of the present utility model and execution mode are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection range of the utility model claim.
