The high efficiency and energy saving 11kV medium voltage drives offered by FGI lead to wide application in iron and steel plants, textile plants and paper mills. Operating at high supply voltages, medium voltage variable frequency drives minimize losses while increasing drive efficiency, reducing system cost and enhancing redundancy possibilities. With 20 years of the leading industrial experiences, FGI aims to give you a range of high voltage motor driver options that meet your every requirement.





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.
