How often should the leveling of wind turbines be checked?

Level inspection of wind turbines should only be carried out during routine maintenance. Generally, routine maintenance is:

1. Inspect, clean and lubricate all rotating parts once a year;

3. Every year of operation, clean the generator bearings. maintain once;

4. Clean, remove rust and paint all exposed parts of the wind turbine every two years.

The electrical energy generated by each rotation of the wind power generator is also different. For example, the most common 2MW direct drive wind power generator, when the wind power is sufficient and stable, the wind power generator generates electricity every 60 minutes. It can form 2000degrees of electricity.

It takes 3.5 seconds for the fan blades to rotate once, and 60 minutes is 3,600 seconds. Therefore, the electricity generated by the generator per second is 0.56 degrees, so the amount of electricity generated by the fan is. the wind power generator for each tower is The power generated is 0.56 × 3.5 seconds, or 1.94 kilowatt hours of electricity.

As the wind volume is unstable, the wind turbine produces 13~25V alternating current, which needs to be rectified by the charger, and then charge the battery to produce the wind. power The electrical energy produced by the generator is converted into chemical energy. Then use an inverter with a protection circuit to convert the chemical energy of the battery into AC 220V mains power to ensure stable use.

Mechanical connection and power transmission: The fan bladeslator with horizontal axis are connected to the universal elastic coupling via the gearbox and its high speed shaft to transmit the torque to the generator drive shaft. This coupling must be. Has good damping and vibration absorption properties.

Performed by absorbing the appropriate amount of radial, axial and some angular deviations, and the coupling can prevent overloading of the mechanical device. The other type is direct drive fan blades which are directly connected to the motor without going through the gearbox. Fan Motor Type
