Due to the fact that a one-way valve is arranged, drying and pureness of air inside the set are further guaranteed. Due to the fact that the multistage axial flow fans are arranged, the air mass flow is increased, and the cooling efficiency is strengthened.
Description
Technical field
The present invention relates to a kind of cooling system, especially relate to a kind of permanent magnet direct-driving aerogenerator group air-flow cooling system.
Background technique
It is necessary that large-scale permanent magnet direct-drive internal rotor air-cooled generator group arranges internal cooling.Have before this two different schemes.It is such that a kind of scheme is arranged: the cabin sealing, carry out temperature regulation with air-conditioning.The enforcement of this scheme is higher to air-conditioning requirement, and the power of air-conditioning must be very high, and air-conditioning must work under the environment of high temperature efficiently, can satisfy the requirement of this harshness and must select military air-conditioning; Unit vibration is also unfavorable to air-conditioning, in case air-conditioning breaks down, easily cause temperature fast rise in motor, might cause compressor emergency shutdown, cause economic loss, What is more, due to the rotor excess Temperature, cause the magnet steel loss of excitation, cause huger loss, so the air-conditioning of two platform independent must be installed, this can additionally increase cost; In addition, adopt this cooling system also will consume more electric energy.
Another feasible scheme is that air enters from the cabin, after motor, then discharges the cabin.This scheme also can be effective, but because the Spatial General 6 R in the cabin is all narrower and small, increases filtrating equipment and breather line from cabin air inlet meeting in the cabin, thereby further tied up the space.In addition, year replacing half a year to one of filter palpus is once changed filter and is changed more inconvenient under tower in the cabin.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of air mass flow that increased for the defective that overcomes above-mentioned prior art existence, has strengthened cooling efficient, and can save the permanent magnet direct-driving aerogenerator group air-flow cooling system in cost and space.
Purpose of the present invention can be achieved through the following technical solutions:
Permanent magnet direct-driving aerogenerator group air-flow cooling system is arranged in cabin and tower cylinder, and the tower cylinder is connected to the bottom in cabin, and this system is the circulating system of filter, axial-flow blower, exhaust duct, netted dividing plate formation, wherein:
Filter: be arranged on the tower cylinder door of wind power generating set, the air of inspiration is filtered;
Axial-flow blower: be arranged on the motor rear cover of tower cylinder door and wind power generating set inside, with air intake or to discharge generator set inner;
Exhaust duct: an end is connected with axial-flow blower on being arranged on motor rear cover, and the other end is communicated to the nacelle exterior of generator set, and the air that sucks generator set inside is discharged by exhaust duct;
Netted dividing plate: be arranged on the end of exhaust duct, prevent that birds and other foreign material from entering.
Described filter is selected air filter for automobile, and in order to reduce resistance of air, layout filter that should be as much as possible when design is to increase filter area.Also to consider the convenience changed during design.
Described tower cylinder door is double layer construction, and the internal layer of tower cylinder door is equipped with two axial-flow blowers.
Described tower cylinder is unimpeded from top to bottom, does not block air ventilation, and inner pylon platform is provided with and hangs thing hole and gap, as the passage of air ventilation.
The axial-flow blower of installing on motor rear cover is connected with the tower cylinder through pipeline section.
One-way valve is installed in described exhaust duct, is guaranteed that air can only be discharged to nacelle exterior in generator set, oppositely can not.
Also be provided with dehumidifier in tower cylinder and cabin, according to the different regions environmental conditions, the quantity that dehumidifier arranges is different.
After Cryogenic air is filtered, axial-flow blower air intake by the place's setting of tower cylinder door, enter again tower cylinder internal channel, sucked in motor by the air intake axial-flow blower that the motor rear cover place arranges by the motor air intake pipe to tower cylinder upper end, can carry out certain stirring to air during the motor operation, then discharge unit by motor row wind axis flow fan by one-way valve, exhaust duct.
Compared with prior art, the present invention takes full advantage of the structure of wind power generating set, utilize the tower cylinder as ventilation duct, saved cost and space, had and filter and dehumidification function, made unit inside form a good working environment, one-way valve the further drying that has guaranteed the unit inner air and pure is set, the multistage axial flow blower fan has increased air mass flow, has strengthened cooling efficient.
