50 Hz / 60HZ High Voltage Power Inverter DSP Cpld Control Up To 10000 KW
1: The modular design of electronic building blocks, power units cascade high voltage inverter.
2: Use multiple rectifier technology with small harmonics and high power factor, meet the most stringent requirements for power quality management.
3: Use multiple inversion technology with small output harmonic and motor torque pulsation, have high operating effiency.
4: Use DSP and CPLD control platform with system control of real-time and high reliability.
5: Built-in PID regulator and terminal programmable function, easy to achieve change control to meet the requirements of process control.
6: Touch screen, program running, analog potentiometers, voltage source, current source, communication interface,etc. Varieties of control instruction input channels, flexible and convenient control mode.
7: AVR functional design: even if there is a large fluctuation in the power grid voltage, output voltage can remain unchanged.
8: Perfect protection function: short circuit overcurrent, overload, phase loss, phase imbalance, rectifier transformer overheating fault can be reliably protected.
9: Multiple bypass design: can bypass the power unit in the system charged situation and frequency conversion system runs continuously.
1. Voltage resource VFD, direct input of 3,3.3,4.16,6,606 and 10 kV,direct output of3,4.16, 6,6.6 and10 kV,no output transformer necessary. High input power factor, low harmonic current, no power factor corrective capacities and harmonic filters required.
2. Sinusoidal multi-level PWM output waveform, no output filter required, can be directly connected to standard induction motor,no harm to the insulation of the cable or the motor, low harmonics of the motor, reduction of vibration of the shafts or the vanes,with the maximal length of the output cable of 1000m.
3. Friendly human-machine interface.
4. Modular design of the power circuits simplifies maintenance routine.
5. The medium voltage circuits are linked with the controller by the optical fibers,which keep the controller safe and away from the disturbance.
6. The complete fault monitor circuit, accurate fault alarm and protection.
7. Integrated cooling blower
8. The control logic can be conveniently changed with the help of the integrated PLC.
9. Offer both field control and remote control in monitor station, providing convenient controlling options.
