Horizontal Shaft Wind Driven Generator Convenient Equipment Installation, Maintenance And Repair
Oct 12, 2017

Horizontal Shaft Wind Driven Generator can be divided into lift type and resistance type. Lift-type rotation speed, resistance type rotation speed is slow. For wind power, the use of lift-type horizontal axis wind turbine. Most Horizontal Shaft Wind Driven Generator have a windshield and are able to rotate as the wind changes. For small wind turbines, this type of wind rudder is used for wind turbines, and for large wind turbines, winds are used as sensors and servo motors.

Horizontal wind turbine style a lot, and some with a reverse blade of the wind wheel; some in a tower to install a number of wind wheels, in order to output power under certain conditions to reduce the cost of the tower; some use of conical cover, So that the air flow through the horizontal axis of the wind when the concentration or spread, so accelerate or slow down; there are horizontal axis wind turbine in the wind around the whirlpool, concentrated airflow. Increase airflow speed.

Horizontal axis wind turbine characteristics

1, start the wind speed is low, high wind energy utilization; small size, good looks, low operating vibration.

2, the installation of user-friendly design, convenient equipment installation, maintenance and repair.

3, the wind wheel blade using a new technology by precision injection molding, coupled with the optimization of aerodynamic shape design and structural design, high wind energy utilization factor, an increase of annual power generation.

4, the generator using patented permanent magnet rotor alternator, coupled with a special stator design, effectively reduce the resistance torque of the generator, while the wind wheel and the generator has a more good matching characteristics, the unit running reliability.

5, the use of maximum power tracking intelligent microprocessor control, effective regulation of current and voltage.

Wind turbine classification, according to its capacity can be divided into: small (10kw below), medium (10-100kw) and large (100kw above) wind turbine. According to the spindle and the ground relative position is divided into: horizontal axis and vertical axis wind turbine. Horizontal Shaft Wind Driven Generator are one of the most successful forms of wind turbines in the world. The main advantage is that the wind turbines can be set up relatively high from the ground, thus reducing the dynamic characteristics of wind turbines due to winds and winds influences. In this paper, after the special instructions do not refer to the wind turbine is a large and medium-sized horizontal axis wind turbine.

(1) fan cabin

The cabin is the key equipment for wind turbines, including gearboxes, generators, and control equipment.

(2) wind wheel hub

The blade is mounted on a fan hub called a wind wheel, which includes a blade, a hub, a main drive shaft, a pitch motor, and the like. One of the most critical components of a wind turbine is the blade, and most of the rotor blades are made of glass fiber reinforced plastic (GRP). Low speed shaft is the rotor shaft and gear box connected together, due to the greater working torque, the speed of less than 50r / min, made by 40Cr or other high-strength alloy steel made.

(3) fan speed changer

Fan gearbox is the gear box, wind turbine is one of the key components.

(4) fan coupling

Between the gear box and the generator is connected with the coupling, usually the coupling and brake design together.

(5) fan brake brake device

The brake is a device that stops the rotation of the wind turbine, also known as a brake brake.

(6) fan generator

Wind turbine is one of the most critical components of the generator, its performance is a direct impact on the overall efficiency and reliability.

(7) tower tower tower

The wind turbine tower tower tower is a support for the wind turbine.

(8) speed control mechanism

The speed of the fan will vary with the wind speed. In order to make the fan wheel running normally smooth the required speed under the device called speed control system, speed control device only in the rated wind speed above the speed of work.

(9) fan steering (yaw) device

The yawing device is a device that keeps the wind wheel upright against the wind.

(10) computer control system for wind turbine

Microcomputer control system is a discrete control, according to the design program gives a variety of instructions to achieve automatic start, running the unit failure of automatic shutdown, over vibration shutdown and other automatic control. Self-fault diagnosis and failure of the computer terminal failure to be repaired, the wind farm crew can achieve fiber optic network management, the failure of the fan in the substation control computer terminal computer terminals and display read out, call out procedures and modify procedures , Modern wind generators to achieve the scene of unattended automatic control.

(11) fan cable torsion cable counter

When the wind turbine is deflected in one direction for too long, the cable will become more distorted, causing the cable to break or other faults. So the wind turbine is equipped with a cable twist counter, and automatic alarm device and automatic cable device.
