Green development is the background color of high-quality development, and new quality productivity itself is green productivity. In industrial production, the improvement of the energy efficiency level of motors, pumps, compressors and other equipment is an effective means to help enterprises achieve efficient production and green transformation. As a new, high-tech energy-saving equipment, high-voltage inverter is the key to achieve energy saving and consumption reduction and improve the process level of motors, pumps and compressors.
The R&D team of high-voltage inverter of CCID Electric Co., Ltd. has conducted in-depth research on key processes such as sintering main pumping and descaling pump in the metallurgical industry, combined with frequency conversion speed regulation technology, to create a highly reliable, intelligent and professional MVC1200 series of high-voltage inverters, which have obtained 8 patents such as "a control system and control method for synchronous switching of high-voltage inverters", "a vector control system without speed sensors for high-voltage inverters", "a high-power high-voltage inverter power unit", etc. It has obtained the Beijing New Technology and New Product Certificate, and has been selected into the recommended catalogue of industrial energy-saving technology and equipment in the field of national industry and information technology, and has been widely used in various industries such as metallurgy, mining, electric power, petroleum, chemical industry, municipal administration, etc., and has been widely praised by customers, making positive contributions to energy conservation and emission reduction in the industry.

Combined with process requirements, the frequency output can be accurately controlled, energy waste can be reduced, and energy saving, consumption reduction and efficient production can be realized.
Applied Practice
The MVC1200 series high-voltage inverter is equipped with the exclusive model of CCID process, which has a more significant energy-saving effect and is currently being applied in all scenarios in the metallurgical industry. For example, in a steel plant, the average power saving rate of the high-voltage inverter of the hot-rolled descaling pump is more than 33%, and the average power saving rate of the converter of a steel mill is more than 25%, which reduces the mechanical impact of the system and prolongs the service life of the equipment, while bringing economic value and environmental protection benefits to customers.
In the early morning of May 21, 2024, the 25-day overhaul of the first workshop of shagang hot coil was successfully completed, and the steel was successfully tested at one time. In view of the application scenario of the synchronous motor drive transformation of the V1 main rolling mill in this project, CCID Electric independently developed and produced the special high-voltage inverter for the synchronous machine based on the MVC1200 series of general-purpose high-voltage inverters, which realized the control of the V1 main motor to switch to the power frequency without disturbance, broke the monopoly of foreign technology, and completed the localization of the equipment. The product adopts advanced control algorithm, which makes the operation of the motor more stable, reduces the vibration and noise during the start-up process, improves the quality of the working environment, increases the protection functions of the motor, and ensures the stable and reliable operation of the motor. At the same time, its start and stop time is faster, so that the whole rolling cycle is shortened, the output is increased, and greater economic benefits are obtained.
