Product Description
The CGV-HA series high-voltage variable frequency speed control system consists of a transformer cabinet, power cabinet, control cabinet, and optional bypass cabinet. The CGV-HA series high-voltage variable frequency speed control system adopts an independent and closed structural design, which improves the system's heat dissipation capability and significantly reduces the installation space required. The entire system has a simple, compact structure that is easy to maintain. It uses an optimized integrated design scheme that not only ensures the reliability of the entire system but also makes it more compact, reducing the installation space requirements for users.
• Independently developed sine wave PWM control technology, fast response, high precision, with a frequency conversion efficiency greater than 98%.
• Uses power unit series stacking technology, which is mature and reliable in performance.
• Modular design of power units for easy maintenance.
• The high-voltage variable frequency speed control system is suitable for a wide range of input voltage, making it more suitable for domestic power grid conditions.
• The high-voltage variable frequency speed control system has an AVR (automatic voltage regulation) function to prevent excessive voltage from damaging the motor's insulation and reducing the motor's no-load losses.
• Flywheel start (speed tracking) function allows the motor to restart while rotating, meeting the continuous production needs of customers.
• Torque boost function increases output voltage at low frequencies, enhancing motor output torque.
• Instant power loss restart function meets the needs of dual power source switching and recovery after power grid failure.
• Unit bypass function automatically removes faulty units when a few units fail, without affecting the overall operation of the inverter.
• Unit bypass reintegration function automatically reintegrates the faulty unit into operation after it returns to normal, improving the operational reliability of the inverter.
• Color TFT touch screen provides Chinese and English language options, with a user-friendly interface for easy parameter input and system status viewing.
• Power units and the main control board use fiber optic communication, providing complete electrical isolation and strong anti-interference capability.
• The main control power supply adopts a dual power source design with an additional UPS, greatly enhancing the safety of the control system.
• Complete protection function design to ensure the safety of the motor and inverter.
• Isolated RS485 interface, standard modbus communication protocol, providing multiple communication methods.
• Fault recording; records parameters during faults for precise fault location, facilitating troubleshooting.
• The output of the CGV-HA high-voltage inverter and its impact on the grid side meet national standards, eliminating the need for filters and reactive power compensation devices, thus reducing the costs of harmonic treatment and grid capacity expansion.
