Product Details

1KV high voltage frequency inverter from China with V/F control WE

 

AS800 series high voltage inverter belongs to the constant voltage type, which will keep high power factor within full speed range, and its full load power factor can be over 0.95, so as to reduce low equipment utilization rate of the user power transformer and power factor compensation problem of the user side caused by low power factor. Fig.2-4 shows power factor comparison between high voltage inverter and phase control thyristor.

               

High reliability and convenient maintenance

IGBT power module of AS800 high voltage inverter has bigger voltage and current design margin, whose trigger and overcurrent protection uses the special driver module circuit with very high reliability. Control signal of inverter is transferred via optical fiber, realizing the reliable electrical isolation of high and low voltage weak current.

AS800 series high voltage inverter adopts modular design, with perfect structural process design and generality for the unit module with the same capacity. If any fault occurs, the simple tool will be used to replace it within several minutes, conveniently and quickly.


High-efficient energy-saving operation method

With the high-efficiently driven energy-saving operation method and new PWM dead zone compensation technology, the loss of motor is reduced efficiently and the energy-saving rate is maximized.

                           


Caring application functions

Several frequency setting method, to meet the complicated and changing site demands;

Special PID control function, to facilitate the process control;

Hopping frequency control function, to avoid the mechanical resonance point effectively;

Power-on self-check function, to provide safety and reliability for every startup.


Wiring

                


Frequency Hopping Function

AS800 series inverter supports to set frequency hopping, 3 frequency hopping points are available.

 Frequency hopping: in order to avoid equipment damage such as motor caused by that the inverter run at point of resonance of mechanical equipment, users can avoid this point of resonance by setting frequency hopping.

 Frequency hopping bandwidth: frequency width, when the inverter hops frequency, shall not be too large, for example (0.5-2), or it may cause overcurrent or overvoltage.


Torque Lifting Function Controlled by V/F

AS800 series high voltage speed governing system provides low frequency torque lifting function, the user may set torque lifting amplitude and speed scope that the torque needs to lift within user-defined V/F parameters adopting the relevant parameter.
