[description of drawings]
Fig. 1 is the partial enlarged drawing of main frame;
Fig. 2 is a stereogram of the present invention.
[embodiment]
Describe the present invention below in conjunction with accompanying drawing:
As shown in the figure, a kind of wind power generating set that adapts to the ultralow temperature area surroundings includes pylon 1 and the main frame 2 that is installed in pylon 1 top.The input end of main frame 2 is connected with wheel hub 4, is connected with impeller 3 on wheel hub 4.In wheel hub 4, be provided with variable pitch speed reducer 5.Described main frame 2 includes support 21, is provided with gearbox 22 on support 21, is provided with bearing support 23 on the axle that gearbox 22 is connected with wheel hub 4.On support 21, be provided with yawing reducer 6.
In order to adapt to ultra-low temperature surroundings, described pylon 1, support 21 adopt the High-Strength Low-Alloy material, and in the present invention, it is Q345E that the High-Strength Low-Alloy material adopts model.Described wheel hub 4, bearing support 23, variable pitch speed reducer shell, yawing reducer shell adopt ductile cast iron material, and in the present invention, it is QT350-22AL that ductile cast iron material adopts model.The High-Strength Low-Alloy material is the test for low temperature impact property under-45 ℃ environment, requires to reach the relevant art index, prevents the brittle failure under ultralow temperature of main machine structure spare.Ductile cast iron material is the test for low temperature impact property under the environment of-45 ℃ of tests, requires to reach the relevant art index, prevents the brittle failure under ultralow temperature of main machine structure spare.
In order further to improve the low temperature resistivity energy of main frame, on described support 21, be provided with heater 7, and can increase the power of heater 7 main frame 2 inner piece heat temperature raisings.When making main frame under low temperature, prepare to start, can heat temperature rise faster to allowing operating temperature.
On described support 21, be provided with air radiator 8 or oil cooling radiator 8 that main frame 2 inner pieces are dispelled the heat.Adopt air radiator 8 or oil cooling radiator 8 can effectively prevent cooling liquid frozen at low temperatures.
In addition, all select for use can be at-45 ℃ of down existence ,-40 ℃ components and parts of work down for each electronic parts and components of master control system of the present invention, frequency conversion system, pitch-controlled system.The hydraulic oil of hydraulic station of the present invention changes Tellus Arctic 32 hydraulic oil that shell gets the man of great strength into, and Tellus Arctic 32 hydraulic oil are that high-performance does not have the zinc antiwear hydraulic oil, and it can be used under extremely low temperature.Also have, some backflow of hot blast that generator of the present invention is discharged enters the cabin.
When outdoor temperature more than-40 ℃ the time, main frame is opened the preparation start-up routine: promptly open equipment such as gear-box heater, control cabinet heater, engine compartment heater, column foot heater earlier; Treat to recover generating gradually after gear case oil temperature, control cabinet are raised to suitable temperature.
After the present invention adopts such scheme, can make blower fan-45 ℃ of-+50 ℃ of existence ,-40 ℃ of-+40 ℃ of normal power generation.
