The FGI`s 10kV series MV drivers have provided reliable service for almost 20 years. To keep that record intact, FGI`s high voltage inveter has developed its high performance characteristics, including vector control technology, multi master-slave control technology, star drift technology, frequency conversion without disturbance switching technology and so on. The medium voltage VFD shows the super energy saving, easy maintenance and high reliability. The high voltage power converter is widely used in harsh fields of coal, mining, metallurgical and chemical industry.





Structure





HMI: Provide users with friendly all-round document operation interface, responsible for dealing with information.


Power cabinet


Each phase is connected in series by a multi-level unit;
Unit standardized structure, 3kV/6kV/10kV unit junction is the same;
The unit communicates with the control cabinet through the optical fiber to control good performance.


Control cabinet


The control core is based on DSP+FPGA, the system is powerful and can meet the customer's needs to the greatest extent;
Independent main control box, plug-in control board, easy to install and maintain;
Rich interface with multiple choices.


Operating Principle


     


The medium voltage drive is composed of switch cabinet, phase shift transformer cabinet, power unit cabinet control cabinet. Among them, the switch cabinet is different according to different sites.The equipment adopts the high-high voltage source type inverter circuit structure, the power units are connected in series, the output is superimposed into high voltage, and directly output to the high voltage motor.
