Audited Supplier Wind Power Generation Pole Turbine Tower Pipe Facility Tubular Metal Steel Fabrication with Preassembly
As the professional foreign standards metal fabricators, we are quite capable to fabricate various wind power generation poles turbile tower based on either EU-US or UK AU etc standard and requirements.
Wind power generation, thermal power generation, nuclear power generation, the electricity they generate has no essential difference except for the size of the capacity; as for the poles used, they are all used to support the wires, so as to maintain a safe distance from others, and the wires on the poles are transmitted. Whether it is wind power or nuclear power, there is no difference in daily life, and there is no difference in utility poles.
The principle of wind power generation is to use the wind to drive the blades of the windmill to rotate, and then increase the speed of rotation through the speed increaser to promote the generator to generate electricity. According to current windmill technology, it is about three meters per second of breeze speed (the degree of breeze) to start generating electricity.
Wind power is becoming a craze in the world because wind power has no fuel issues and no radiation or air pollution.
Wind power generation is very popular in Finland, Denmark and other countries; my country is also vigorously promoting it in the western region. The small wind power generation system is very efficient, but it is not composed of only one generator head, but a small system with certain technological content: wind generator + charger + digital inverter.
A wind turbine consists of a nose, a swivel, a tail, and blades. Each part is very important, and the functions of each part are: the blades are used to receive the wind and turn into electrical energy through the nose; the tail makes the blades always face the direction of the incoming wind to obtain the maximum wind energy; the swivel can make the nose flexibly rotate to achieve The function of adjusting the direction of the tail; the rotor of the nose is a permanent magnet, and the stator windings cut the magnetic lines of force to generate electricity.
Due to the unstable air volume of the wind turbine, the output of the wind turbine is 13-25V alternating current, which must be rectified by the charger, and then the battery is charged, so that the electrical energy generated by the wind turbine can be turned into chemical energy. Then use an inverter power supply with a protection circuit to convert the chemical energy in the battery into AC 220V mains power to ensure stable use.
Mechanical connection and power transmission The horizontal axis fan blade is connected to the universal elastic coupling through the gearbox and its high-speed shaft to transmit the torque to the drive shaft of the generator.
This coupling should have good absorption, damping and vibration. The characteristic is to absorb the right amount of radial, axial and angular offset, and the coupling can prevent the overload of the mechanical device. The other is a direct-drive fan motor type that is directly connected to the motor without a gearbox. Generator: Often referred to as an induction motor or an asynchronous generator.
On modern wind turbines, the maximum electrical output is typically 500 to 1500 kilowatts. Yaw device: Turn the nacelle with the help of an electric motor so that the rotor is facing the wind. The yaw device is operated by an electronic controller, which can sense the wind direction through the wind vane. The picture shows the wind turbine yaw. Typically, wind turbines only deflect a few degrees at a time when the wind changes its direction.
