Since the early days of human development, wind energy has been used as an energy source, and with the development of science and technology, people have begun to use wind energy more accurately. How to make better use of wind energy to bring convenience to human life has always been the direction of human efforts to explore.
The application of high voltage, high current sensors, vibration sensors, temperature, humidity, wind, position and pressure sensors has been promoting the steady development of the wind power industry. Among them, because the position sensor is an essential component in the variable pitch control system and transmission, it is particularly important in the wind power industry.
Look! How LANBAO sensors gallop in wind power industry!
一. Wind Turbine Composition
1.Blade + fairing + variable motor
2.Gearbox (planetary gear structure)
3.Electric generator
4.Transformer
5.Swivel
6.Tail wing
7.Control cabinet
8.Pylon
二. Two Control Systems
1.Variable pitch control system: to adjust the windward angle of the blade.
2.Yaw control system: adjust the windward angle so that the windmill is always facing the wind direction to obtain maximum wind power.
LANBAO position sensor LR18X series controls the aerodynamic torque captured by the wind wheel by adjusting the pitch angle of the blade and changing the attack angle of the air flow to the blade in the variable pitch control system.
LANBAO Proximity position sensor LR18 series uses a set of planetary gear structures in the gearbox to convert the low speed of the main shaft into a high speed to drive the generator. The proximity sensor is mainly used to detect the spindle speed.
三.LANBAO Product Recommendation
LR18X-IP68 Inductive sensor with high protection grade
•The shell is made of stainless steel SUS304 material, which can resist the high salt and high humidity environment, making the product unbreakable.
•IP68 protection grade, suitable for long-term wet and heavy washing applications.
•The combination of nuts and inner tooth gaskets makes the installation more firm, even in a vibrating environment, it also works as one.
•With extended temperature range of -40-85°C, it is stable regardless of cold or heat.
•With a response frequency of up to 700Hz, even if the wind power is at stall, it remains in control
