Product Features of 1000W wind turbine:
1) High quality
Hummer 1kW wind generator adopt two SKF (Svenska Kullager Fabriken) bearings which are produced by the largest bearing manufacturer in the world, with the perfect internal geometric structure, known for its life-time endurance and reliable quality.
2) Low noise
The design of the rotor blade of Hummer 1kW wind generator absorb the highlights of the small aircraft's airfoil, which is compliance with the aerodynamic standards. It provides a more aesthetic look and a higher efficiency and reduces the noise production as much as possible.
3) Double braking protection
Hummer 1kW wind generator adopt the double braking protection system, which are the yawing mechanism and the electromagnetic braking system to regulate the rotation of the wind turbine. It is safe and convenient to shut down the whole system both manually and automatically.
Structure and component parts:
1. Generator Part
It is composed of the patented SCF generator, the nose cone, and the protection cover.
2. SKF Bearings
Two SKF bearings ensure the reliability the longevity of our generator. Wide temperature ranges: 150-350º C. Long life span, reach up to 60000-100000 hours. User may not change the bearing during the wind turbine using.
3. Flange & Blades
The flange is made of fine steel, used to fix the blades to the rotor. The blades are made of glass reinforced plastic, efficiently turn the wind energy into the mechanical energy. Every set of the three blades has passed the strict balance test before the shipping.
4. Yaw Shaft
It is made of fine steel and used to connect the generator and the blades to the tower. Powered with a 24V motor and integrated with a gear box, which are able to regulate the direction of the generator.
5. Dogvane & Anemometer
They receive the signals of the wind direction and the wind speed.
The dogvane reads the average value of the wind direction every 120 seconds. If the angle between the dogvane and the wind generator axis depasses 10° , the 24V motor will drive the yaw shaft to turn and follow the wind direction automatically.
The anemometer mesures the realtime wind speed. If the wind blows non-stop over 3m/s during 20 seconds, the automactic wind tracking program will start to make the rotor blades surface face the wind correctly; If the wind speed drops below 3m/s, the tracking program will turn to stand-by.
6. Off-grid Inverter & On-grid Inverter
Hummer off-grid inverter adopts SPWM (Sinusoidal Pulse Width Modulation) technology, is able to invert DC with higer efficiency into AC with stable frequency and voltage, filters the noise as well.
Hummer on-grid inverter adopts MPPT (Maximum Power Point Tracking) technology and IGBT (Insulated Gate Bipolar Transistor), is able to invert DC with a high power producing capacity and a wider AC voltage output range. It connects to the public grid and there is no need for any power storage device.
7. Siemens Module PLC
Hummer PLC (Programmable Logic Controller) adopts the Siemens controlling module and is equiped with a touch screen. It can alarm and adjust the abnormal running status of the wind turbine automatically. Siemens module offers high reliability to our PLC and its customers worldwide can testify for that. It easy to control and operate your wind turbine via our PLC easily and efficiently.
8. Rectifier/Dump Load Controller & Dump Load Box
The controller controls the process of which the alternative current produced by wind turbine into direct current and eventually charges the battery bank with DC. It also controls the switching on and off of the dump load to protect the system against the risk of being overloaded with too much power.
Metal box design of the dump load radiates the heat of the resistance inside quickly via the air convection. So there is no need for an extra fan.
