Qingdao Richuan Precision Machinery Co., Ltd.
Richuan brand direct drive 20kw vertical shaft wind turbine
Introduction
Use 20KW Wind Generator System to generate electricity which charge into storage battery group (off grid) or feed into the grid net (on grid). Through the multi-voltages power supply system, the 3 phase wind power voltage can be rectified into DC and convert to AC power used for home, commercial or other industry power supply application
when the wind speed 1.8 m/s breeze, vertical axis wind turbines can start, the improve the efficiency of the wind.
Rated power:20 kw
Yawing mode: PLC automatic yawing
Start-up wind speed:3 m/s
Rated wind speed:12m/s
Rated voltage: 3AC 360v
1. When the wind speed 2.5m/s breeze, vertical axis wind turbines can start, the improve the efficiency of the wind, it is out of reach for other wind power equipment.
2. The windward side orientation can be determined by the wind vane sensors to automatically track the direction of the wind, the wind blades can automatically adjust the windward surface deflection Angle, according to the size of the wind speed increase or decrease the windward area, maximum efficiency of using wind and under the condition of the high wind speed limit power equipment high-speed rotation and at a constant speed, in order to protect the whole system.
3. This product for a low speed 40 RPM reach the rated speed, low noise, noise under 59 db.
4. When the device's current, voltage, high speed, wind speed, automatically realize wind yaw protection. For cold area, we have blades heating function, to prevent freezing..
5. Our products can also set the man-machine interface to control the entire system, as long as there is network, can remotely monitor and check the working state of wind turbines and information material.
6. Our wind generator is a kind of ideal power supply system, will be, off-grid grid. Widely used in mountains, island, grassland, desert region, such as farm, and ships, meteorological station, TV ChaZhuanTai, observatory, resorts, such as wind farms abundant local and grid is difficult to reach areas.
Feature
