Sinochem New Network News Anshan City Quanyu Electronic Power Co., Ltd.'s capacity-enhancing high-low voltage variable frequency speed control energy-saving technology is a combination of "frequency conversion + energy saving + capacity + material". It can be used in high-voltage (3~10 kV), medium-high power (200-2000 kW) motor frequency control of medium and large-sized wind turbines, pumps, compressors and other drag systems in metallurgy, chemical, mining, petrochemical, coal and other industries. In the transformation and new construction projects, the purpose of large-scale power saving, material saving, capacity enhancement and efficiency increase will be realized.
The technical principle is to use the patented technology to make the high-voltage motor improve the rated power of the motor while keeping the magnetic flux density and current density basically unchanged. At the same time, the high-power inverter input voltage compensation technology is used to realize the best motor excitation of the high-voltage motor. Frequency control and maximum power output, finally improve the output power of high-voltage motor 1 to 3 power levels, increase the output power of the inverter 1 to 2 power levels, improve the production capacity of transmission equipment by 10% to 20%, and achieve a power saving rate of 20 % to 60% of the indicator.
At present, the technology products have been widely used in petrochemical, metallurgy, coal and other industries more than 60 medium and large pumps, wind turbines, air compressors and other transmission equipment high-voltage motors, including Liaoyang Chemical Fiber Corporation power plant 4 sets of water supply pump high-voltage motor capacity Energy-saving technology renovation project; Liaoning Jinhua Machine Company Centrifugal Compressor Experimental Bench imported high-voltage motor capacity-enhancing energy-saving new project; 6 sets of slurry pump high-voltage motor capacity-increasing energy-saving technical transformation project of Qigangshan iron ore dressing plant of Anshan Iron and Steel Co., Ltd.; Iron and steel pumping station 2 sets of high-voltage motor capacity-enhancing energy-saving technical transformation project; Fushun Xinfu Steel dust removal system induced draft fan high-voltage motor capacity-enhancing energy-saving technical transformation project; Jilin Petrochemical Company power plant 3 sets of water supply system implementation of high-voltage motor energy-saving water-saving technology transformation Wait.
