Description

ABB S-073H 3BHB030477R0207 phase module

Function and Principle
It belongs to the same series as the S-073H 3BHB009884R0204 module. The modular multilevel converter (MMC) technology is adopted to convert direct current electrical energy into alternating current electrical energy with adjustable frequency and voltage and precisely controlled phase, providing power for high-voltage alternating current motors and achieving the speed control of the motors. By controlling the on and off of components such as IGBT in the sub-module, the required AC voltage waveform is output to meet the operational requirements of the motor under different loads.

Main application fields:
Power industry: It is used for the speed control of large motors in power stations, such as induced draft fans, forced draft fans, feed water pumps, etc. By precisely adjusting the motor speed, the air volume and water volume can be flexibly adjusted according to the actual operation requirements of the power station, improving the motor operation efficiency, reducing energy consumption, and at the same time optimizing the power production process to ensure the stable and efficient operation of the power station.
Petrochemical industry: It plays a significant role in equipment such as oil pipeline pumps, chemical process pumps, and compressors. It can precisely control the motor speed according to different working conditions in the production process, achieve precise adjustment of process parameters such as flow and pressure, ensure the stability of chemical production and product quality, and at the same time reduce energy consumption and production costs.
Metallurgical industry: It can be applied to equipment such as blast furnace blowers and steel rolling mills. It can quickly adjust the motor speed according to the requirements of the steel production process, achieve precise control of the blast furnace air volume and the rolling speed of the steel rolling mill, improve production efficiency and product quality, reduce energy waste, and enhance the overall benefits of metallurgical production.
Mining industry: Applicable to motor control of equipment such as mine hoists, ventilators, and crushers. According to the actual situation of mine production, the motor speed can be flexibly adjusted to improve the operational efficiency and reliability of the equipment, reduce equipment wear and energy consumption, and ensure the safety and efficiency of mine production.
