China Shipbuilding Heavy Industry News, recently, from the July 12th, good news came from the National Development and Reform Commission's major industrial technology development project - high - voltage, large-capacity inverter energy-saving technology development, after more than three years of research and development of scientific and technical personnel, Successfully tackled key core technologies and developed a high-voltage variable-frequency speed control system with a capacity level of 8MVA , and achieved stable operation at full power.
At present, the current situation of energy shortage and environmental pollution restricts the sustainable development of China's industry. How to use energy in an efficient and sustainable way has become a top priority. The frequency conversion energy-saving technology is known as the “ energy-saving crown †of modern industry , especially the high-capacity high-voltage inverter, which is the core equipment used in the safe operation and energy saving of large-scale motors in the current high-energy-consuming industry. The successful development of the project marks that China's high-pressure large-capacity converter technology has reached the international leading level, breaking the long-term monopoly of a few manufacturers, filling the domestic gap and promoting the leap-forward development of the domestic variable-frequency transmission technology. This type of frequency converter has the advantages of high voltage level, high power density, improved system efficiency, frequency conversion and energy saving, etc. It can be widely used in power grid and other industrial control fields. If it is popularized in large-scale motor energy consumption systems such as mining, metallurgy, chemical industry, petroleum, textile, power plant, etc., it will save a lot of energy for the country, and the economic benefits are very significant.
712 has long been committed to the research and development of high-power power electronics technology, and strive to create high-end inverter products with independent intellectual property rights. In the second half of 2008 began supporting research major national industrial technology development, "high-power high-voltage inverter" key project, after more than three years of research and prototype development, broke through several key technical high voltage power inverter system, and successfully applied for One invention patent, one utility model patent. Subsequent tests have proved that the system greatly reduces the power consumption of the motor load, saving more than 30% , greatly improving the utilization of electric energy.
At the same time, 712 actively built a high-end inverter industry development platform, accumulated process and manufacturing experience, effectively formed a product conversion of superior technology, and related products have been successfully applied to large-scale motor test platforms and ship propulsion systems, boosting technology and products. Continuous innovation. The successful development of the project has also laid a solid foundation for the industrialization of high-end inverters, which will greatly promote the service life of major equipment and improve the development level of the entire national economy.
