wind turbine/windmill/wind power/wind energy

Characteristic of our products

1. Special design of magnetic circuit is to generate the power at low wind speed. The cut in wind speed is 3m/s.

2. The superior brand raw materials for bearings and alnico, which has good capacity of thermal diffusivity and magnetic.

3. To make the cable of top part of wind turbine do not twist and broken, we take the 3slip rings and 3copper brushes technique to transport the power.

4. The generator is made of ductile cast iron pipe or steel tube which is good at working even at severe atmosphere.

5. The blades are made of the good glass fibre reinforced plastic, which are good at starting up quickly and can work normally at throng wind weather.

6. Safe protection methods are done well through rotating shaft, swing-tail and electric controls of variable propeller pitch technique and the wind turbine systems do not need workers to maintain.

7. Our wind turbine can be used in base station of power, wind-solar hybrid-street lamp system series, small power supplier and wind field

8. Systems of 10kw-50kw take downwind structure and do not have frequently mechanical controls. The wind turbine systems adjust automatically according to the different wind direction and wind force. The control systems of wind pressure which powers the variable pitch are well used in variable pitch. When the wind turns stronger and stronger and even over the rated wind speed, the blades adjust themselves to reasonable angles to meet the present wind speed and the max angle is 90°. Then the whole system protects itself by this way. For 20kw, 30kw and 50kw, manpower brake apparatus are used. When the wind is very strong or repairing the system, the manpower brake apparatus makes double safety of the whole system. Closed collecting rings which is intense current and brushes are used in transmission of the power generating by wind. Its strong point is making the cable work normally when the wind directions are unstable, no twist.

Kinds of variable pitch are, adjusting the blades direction according to the wind speed and the max angle is 90°.

     We abandon the technique of worm and gear, hydraulic technology and gear rotary. Out loading part: when the battery is full, the box of out loading will use up the extra power and hen the blades will stop under the electric controls of variable propeller pitch

Controls inverter system

1. The non mechanical-contact of field effect transistor (FET) is well design and is applicable in controls, which is high reliability, shockproof and longed-lived.

2. Mature technique of high frequency circuit is applicable in not big rated power inverters. The strong point of our inverters is light weight, good efficient and low heat productivity.

3. The controls and inverters can protect itself when we take wrong operation.

4. The controls have special self-protection capacity of out loading, which can guarantee the controls inverter work normally.
