Yuanda Group launches large capacity high voltage frequency conversion drive system
Recently, the reporter learned from Shenyang Yuanda technology electrician Co. , Ltd. that the company produces 25MVA (Mega-volt-ampere)
The large-capacity inverter will be sent to Laos in next January for gold mining.
The advent of 25MVA inverter not only brings economic benefits to Yuanda Enterprise Group, but also breaks the long-term monopoly of international brands such as Siemens, ABB and GE in the field of Mill Drive, it ended the history that our country was controlled by foreign enterprises in the field of high-end mining equipment drive.
Yan Lingyu, vice president of technology of Shenyang Yuanda Science and Technology electrical company, told reporters that the personalized demand of the market brings personalized demand for motor control, and these personalized speed regulation requirements are realized by frequency converters.
Inverter is the core supporting system of the motor. It can control the power control equipment of AC motor by changing the frequency of the motor's working power supply, and can provide the required power supply voltage according to the actual needs of the motor, to achieve energy saving, speed regulation, and then change the speed of the motor, to achieve special process performance or energy saving.
With the continuous improvement of industrial automation, frequency converters have also been widely used. '
Inverter has been applied in China's industry for 20 years. At present, it has been widely used in the fields of motor drive such as petroleum and petrochemical, metallurgy, electric power, mining, ship and marine engineering.
However, high-power, high-performance and high-reliability high-end products are still controlled and monopolized by foreign companies. '
Yan Lingyu said that the inverter has a market of tens of billions of yuan every year, and its market share is still growing rapidly, with domestic inverters accounting for 60% of the market, however, this 60% market share rarely includes high-end and core technology products with high added value.
Because of the monopoly and technology blockade of foreign enterprises, the high profits are earned by foreign enterprises in vain, so the localization of the high-power Mine Mill frequency conversion drive system project is of great significance.
Yuanda Science and Technology electrician has targeted at this market, and has been developing high-end market applications of frequency converters since 2009. It took five years to successfully develop large-capacity high-voltage frequency converters.
Its successful research and development has made Yuanda Science and Technology electrician a domestic manufacturer that can provide such high-power motors and frequency converters at the same time. '
The inverter has the largest capacity in the world in the field of mill matching, and is characterized by being able to make adjustments according to technological requirements and personalize the motor control.
It can not only be used in traditional industries, but also in high-end markets such as long-distance pipelines and nuclear power main pumps. 'Yan Lingyu said.
