The 6kV medium voltage drives is a product accumulated by FGI for over 20 years. The 6000V medium voltage frequency converter adopts modular design, mainly including phase shift transformer cabinet, power unit cabinet and control cabinet, etc. The medium voltage motor starter has the advantages of low input harmonic content and high power factor. The 6kV MV VFD drives are widely used in pumps, fans, woodworking machinery, cement production and other industries. The MV inveter has high performance and super energy saving advantage.





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.
