Medium Voltage Solid Soft Start Device
Medium Voltage Frequency Inverter
The system adopts the current stable, reliable and advanced power unit cascade technology, with DSP+FPGA+CPL D processor as the control core, PLC as the user interface, and touch screen as the human-computer interaction interface.

Medium voltage Arc Extinction Cabinet
In normal operation, the microcomputer controller continuously detects the voltage signal provided by PT. Once the system has PT disconnection, single-phase metal grounding or single-phase arc grounding, its auxiliary secondary open triangle voltage will immediately change from electrical low level to high level.

Active Harmonic Power Filter
The active filter detects the load current in real time through the external current transformer CT, and extracts the harmonic components of the load current through the internal DSP calculation. Then the PWM signal is sent to the internal IGBT to control the inverter to generate a current equal to the load harmonic and in the opposite direction into the power grid to compensate the harmonic current, to achieve the filtering
function.
