Overview of New Vertical Axis Series Wind

Turbines1.1

Overview

At present, the vertical axis wind turbine in the market is a mixed bag of fish and dragon, with a wide variety of types. In practical applications, the efficiency is basically extremely low, and there are also safety issues in operation. The rotation mode of a vertical axis wind turbine is different from that of a horizontal axis. The rotation of the blades will damage the wind force themselves, resulting in a reaction force and extremely low power generation efficiency.

Our company has introduced a vertical axis that can rotate and revolve. During operation, the blades of this model can rotate themselves, and the entire impeller rotates around the center in a circular mode, effectively avoiding reverse forces caused by impeller rotation and wind direction. There is no reverse force or related resistance, thus greatly improving the efficiency of power generation.

1.2 Performance and advantages

performance

1. High power generation efficiency, able to achieve electricity output under low wind speeds.

2. Low speed, low noise, strong resistance to strong winds, and high safety factor. Due to the use of resistance type blades, the operating speed will never exceed the speed of the wind during operation. When the blade speed ratio is 0.7, it will operate safely at a wind speed of 30m/s.

3. The mechanical structure is reasonable and the failure rate is low.

4. The blade assembly can achieve self rotation and revolution, without causing wind resistance during operation and affecting power generation.

5. The utilization coefficient of wind energy is more than three times that of the conventional vertical axis.

6. Adopting a unique sealing structure, achieving thorough moisture and dust prevention.

7. Adopting direct drive permanent magnet generator and efficient rare earth material.

3.1 safety precautions

Ø The installation of the fan system must be carried out by qualified professionals.

Ø Before installation, wiring, operation or maintenance, it is necessary to have a comprehensive understanding of the installation, operation or maintenance requirements of the fan or system.

Ø Properly use appropriate insulation tools and protective devices to reduce the risk of electric shock.

Ø When installing the crane, personnel should not stand under the fan tower or its middle arm.

Ø Do not use unsafe equipment and tools.

Choose a sunny day with a wind speed of less than 5m/s for installation.

3.2 Readiness and precautions

Ø Count all equipment according to the shipping list and confirm that they are complete and undamaged;

Ø The electrical control equipment such as the wind turbine control system is indoor and must be placed indoors, otherwise it may cause equipment damage;

Ø When installing multiple wind turbines, they should be placed differently according to the labels on the equipment packaging to avoid situations where the outgoing lines cannot be connected properly;

Ø The distance between the wind turbine and the wind turbine control system is required to not exceed 50m to reduce transmission losses. Before installation, confirm the distance from the wind turbine installation point to the electrical control room and the layout of electrical equipment in the electrical control room. Purchase sufficient cables according to the manufacturer's cable
