690V Liquid-Cooled Doubly-Fed Converter
2.0MW, 2.5MW, 3.2MW, 4.2MW, 5.0MW, 6.25MW
Performance characteristics
High Power Density
The maximum unit power is up to 6.XMW and the power density is raised by 100%
High Reliability Design
The product's high IP rating makes it particularly suitable for highly saline and misty, polluted, and humid environments
Flexible Layout
The block-style design supports flexible arrangement and facilitates the expansion into one converter unit integrated with master control unit/liquid cooler
Lightweight Parts
A single power module weighs 11kg, and the maximum weight of wearing parts does not exceed 20kg, making it convenient for one-person maintenance
Customized Inlet and Outlet
The cable entry of the grid, stator, and rotor can be customized to meet diverse requirements of the tower base and nacelle
Remote Monitoring and Intelligent Diagnosis
The remote network system of the converter can intelligently diagnose wind turbine faults
