Product Description
High Efficiency Wind turbine 20KW wind generator
1. FEATURE&MATERIAL
SCF Supercritical generator
Hummer's 20KW wind turbine power adopts SCF supercritical technology which won a gold award in the 37th Salon Eureka in Brussels. This technology significantly reduces generator's weight and size down to 25% to 30% of the traditional one, and the production efficiency is 25% to 30% higher. This ensures that the generator functions perfectly in small wind condition.
SKF bearings
Hummer wind turbine adopts 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. Ordinary bearings need to be changed every two or three years, while SKF bearings can greatly reduce the maintenance costs on this matter.
PLC integrated with Siemens module
Hummer wind turbine's controlling system adopts the smart touch-screen PLC (Programmable Logic Controller) which is integrated with Siemens controlling unit. The PLC will alarm and adjust the abnormal running status of the wind turbine automatically both timely and efficiently. Siemens module offers high reliability to our PLC and its customers worldwide can testify for that.
Low noise
The design of the rotor blade of Hummer 20KW wind turbine absorbs 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.
Triple braking protection
Hummer 20KW wind turbine power adopts triple braking protection system, which are the yawing mechanism, the electromagnetic braking system and the hydraulic braking system to regulate the rotation of the wind turbine. It is easy and convenient to shut down the whole system both manually and automatically.
2.20KW on grid wind generator system grid tied wind turbine is composed of:
Wind generating system: Generator, blades, yaw shaft, dogvane, anemometer power cables
PLC controller: Siemens PLC control module with touch screen
On grid retifier: Convert the unstable AC from generator to stable DC
Dumping load: Protect the system from over voltage, over current, over heat etc
On grid inverter: Single phase and three phase options
Tower: 16m free standing tower, 17.33m hydraulic tower are standard options
