Mining Flameproof and Intrinsically Safe High-Voltage Variable Frequency Speed Regulation Integrated Machine
The frequency converter and motor are integrated with a detachable and compact structure;
Disconnection function between the frequency converter and motor input/output, enabling quick switch between power frequency and variable frequency modes. Independent operation of both components facilitates easier maintenance;
Advanced NPC Type I three-level topology technology with low output harmonic distortion and reduced voltage reflection; it is more motor-friendly;
New DSP control technology to carry out intelligent online diagnosis of system faults;
Adaptive power balancing for multiple units based on CAN bus without manual intervention;
Overall efficiency ≥95% under full-load and overload conditions;
Multiple protection functions including overload, short circuit, overvoltage, undervoltage, phase loss, phase failure, and power component overheating protection;
Suitable for various operational requirements of scraper conveyors, including soft start, controlled variable-speed or fixed-speed load operation, normal shutdown, emergency shutdown, and forward/reverse rotation control.
