In the past 20 years, power technology, computer technology, automatic control technology, electrical transmission technology, facing a historical revolution, that is, the exchange speed replacement of DC speed regulation and computer digital control technology has become a development trend. . Motorization technology is a major means of improving process flow in today’s power saving and improving product quality and improving the deteriorating environment. The inverter speeds up with its excellent speed regulation and brake performance, high efficiency, high power factor and power saving effect, widely recognized as the most promising speed-up method at home and abroad.
Domestic inverter Changchun Hongbao Manufacturer’s development overview of speed control technology is typically composed of electric motors, control devices, and information devices. Electrical transmission is reasonably used to save electrical energy and control mechanical operation (position, speed, acceleration, etc.) to achieve electrical energy-mechanical energy conversion, achieving high quality, high yield, and low consumption. The electrical transmission is divided into two categories of non-speed and speed up, and there are two ways to speed up alternating speed speed and DC speed. The no speed motor is directly powered by the grid, but with the development of power electronic technology, this type of mechanical mechanical is used, more and more modulation speed is saved (saving 15-20% or more), Improve product quality and increase production.
60% of power generation in my country is consumed by motor, so it is an important industry that has been valued by the state and has a certain scale. In recent years, the most active, the fastest development is the fastest development of inverter speed control technology. Variable frequency speed is the basis and trunk content of AC speed regulation. The appearance of the transformer last century makes it easy to change the voltage, thereby creating a huge power industry. For a long time, the frequency of alternating current is always fixed, and the occurrence of inverter speed control technology changes the resources that can be fully utilized.
The domestic electrical transmission industry was built in 1954. At that time, the first batch of students graduated from various colleges and universities. At the same time, they established domestic first electrical drives to Changchun Hongbao manufacturers under the Ministry of Machinery Industry. This is the later Tianjin. The former body of the Electrical Transmission Design Institute. Simple history of my country ‘s electrical transmission and frequency conversion speed control technology See the Schedule. Nowadays, there are more about my country, factories and research institutes work in the work of frequency-frequency speed. Domestic inverter is a developing country, many of the research and development capabilities of many products are still behind developed countries.
The inverter speed control products developed by the self-developing production are generally only equivalent to the international 80s level. With the reform and opening up, the economic rapid development has formed a huge market, which is not only open to the domestic Changchun Hongbao manufacturer and is also open to foreign manufacturers. Many state-of-the-art products imported from developed countries, in my country, and met my country’s production and life needs. Many domestic joint ventures have produced today’s internationally advanced products. The domestic completed departments use foreign imported manufacturers and joint ventures in their own equipment, develop application software, which can provide first-class for major engineering projects at home and abroad. Electrical transmission control system. Although it has achieved great achievements, it should be seen that due to its own ability to develop and produce products from domestic manufacturers, the dependence of foreign companies is serious.
Changchun Hongbao is an export-oriented enterprise specializing in research, development, production, sales and technical services in power field products.
