Grid-Adaptive Wind Turbine Frequency Converters with Model No.: 30

1. Overcurrent tripping of the frequency converter: The cause may be sudden changes in the load of the frequency converter or motor stalling. The solution is that you can check for mechanical jamming and extend the acceleration time. 2. Motor abnormal noise: This may be caused by harmonic interference or bearing wear. It is recommended that you install an output reactor and replace the motor bearing. 3. Overheating of the frequency converter: It is caused by poor heat dissipation of the frequenc

Choose according to the rated power of the motor, and it is recommended to reserve 10%-20% redundancy. If the load includes impact equipment, it should be selected according to 1.5 times the rated current of the motor. For example, a 110kW water pump should choose a 132kW frequency converter.

Enable the 'automatic energy-saving operation' function, and the frequency converter will automatically adjust the V/F curve to the optimal efficiency point. Adopt the combination of variable frequency pump and power frequency pump, and dynamically distribute the load through PID adjustment to avoid long-term high-load operation of a single pump.
