Recently, in the "2012 National Torch Program Project" issued by the Ministry of Science and Technology of the People's Republic of China, the "RNB6000 Frequency Conversion Governor" independently developed by Reynolds was included in the "2012 National Torch Program Project List" with its domestic leading skills and efficient energy-saving conversion power. This marks that Reynolds has received further support from the state in promoting the industrial development of "frequency conversion speed regulation", and proves that Reynolds has obtained the leading advantage of skills in the field of frequency conversion speed regulation through independent innovation.
It is understood that the "Torch Program" is approved by the State Council and organized by the Ministry of Science and Technology of the People's Republic of China, aiming to promote the productization of high-tech achievements, the industrialization of high-tech products, and the internationalization of high-tech industries. The program is market-oriented, mainly supporting high-tech products with independent intellectual property rights, giving priority to supporting serious special projects of industrial clusters that have a leading and supporting role in economic development and high-tech product development projects with core skills and in line with national key support skills.
Frequency conversion speed regulation technology is one of the main directions of modern electrical transmission, it is not only smooth speed regulation curve, large speed regulation range, high power, small starting current, stable operation, and good energy-saving effect, is the best energy-saving products for all transmission equipment such as fans and pumps, and is the key implementation skills to complete the "Twelfth Five-Year Plan" energy conservation and emission reduction policy. The use of frequency conversion speed regulation technology can improve the control accuracy, production power and product quality of the production machinery, which is conducive to the automation of the production process, so that the AC drag system has excellent control performance, and has a significant energy-saving effect in many production occasions. The use of inverter to drag the motor, the starting current is small, can complete the soft start and stepless speed regulation, convenient for acceleration and deceleration control operations, so that the motor greatly saves electric energy, in line with the current international and domestic vigorously advocate the use of energy-saving and consumption-reducing products of the creative, is now the national encouragement production project.
Reynolds high and low voltage variable frequency governor can achieve an average power saving of 30% without replacing the host equipment, saving a lot of power for the country. It has an important driving force and huge radiation to promote the adjustment of China's industrial structure, optimize and upgrade the industrial structure, and develop the intelligent control industry of electrical appliances and high-efficiency, energy-saving and consumption-reducing products.
