SPWM Air Cooled medium High Voltage VFD Variable Frequency Drive ODM

ZF-BP Series Air Cooled High Voltage Variable Frequency Drive

Air cooled high-voltage frequency converter is a high-voltage motor speed control equipment based on advanced power electronics technology, which achieves efficient operation through air cooling and heat dissipation. It is widely used in industrial fields such as power, petrochemical, metallurgy, water, cement, etc.

Technical Principles and Structural Characteristics

The air-cooled high-voltage inverter adopts IGBT power unit series multilevel technology, combined with vector control and SPWM control technology, to achieve variable frequency speed regulation of high-voltage motors. The core cooling system is designed with forced air cooling, utilizing fans to accelerate air flow and efficiently dissipate heat from power devices and transformer coils, ensuring stable operation of the equipment. Typical structures include:

• Power unit: Built in forced air cooling module, working in conjunction with the air duct through a radiator.
• Control cabinet: integrates the main control unit and fiber optic communication module to achieve rectification, inversion, and real-time monitoring.
• Cooling system: adopting modular heat pipe shovel tooth radiator and phase change heat conduction technology, breaking through the power limitation of traditional air cooling

Application advantages

• Efficient and energy-saving: By adjusting the motor speed to achieve precise load matching, energy consumption is reduced by 20% -40%.
• High reliability: With redundant design and long-life components, the system's MTBF (mean time between failures) exceeds 20 years.
• Strong environmental adaptability: It can operate stably in environments ranging from -5 ℃ to 40 ℃, meeting the requirements of harsh industrial scenarios.
• Low maintenance cost: Combining natural convection with forced air cooling reduces the need for water cooling system maintenance.
