Le fournisseur d'unités de retour d'information rappelle que les convertisseurs de fréquence constituent un investissement important dans le secteur de l'énergie et de l'électricité, principalement utilisés pour économiser l'énergie et améliorer les processus de production. Leur développement futur sur le marché reste toutefois incertain. Les convertisseurs de fréquence, dispositifs d'économie d'énergie et de régulation de vitesse pour moteurs, sont largement utilisés dans la métallurgie, l'énergie, la distribution d'eau, le pétrole, la chimie, le charbon et d'autres secteurs. Leur analyse de marché est présentée ci-dessous :
1. Industrie métallurgique :
L'application des convertisseurs de fréquence dans le secteur métallurgique concerne principalement les laminoirs, les bobineuses, les ventilateurs, les pompes à boues, etc., pour les tôles et les fils, avec pour objectif principal l'économie d'énergie des moteurs.
2. Industrie de l'énergie électrique :
China's power generation capacity ranks second in the world, second only to the United States. The power industry is also one of the important application areas of frequency converter products. From the perspective of the control process associated with frequency converters in China's thermal power plants, the transmission devices of wind, coal, water, slag, and exhaust systems are all suitable for the use of frequency converters. Among them, except for the coal system (powder discharge machine, coal feeder), the other four types of systems are mainly loaded with fans and water pumps. The products of frequency converters are primarily used to modify coal, powder, water, etc., in order to adapt to changes in load and ultimately achieve the intention of saving power and improving control technology. They are of great significance for energy conservation, consumption reduction, emission reduction, safety, and stable operation of thermal power plants.
3. Water supply:
The water supply and drainage system, sewage treatment system, etc. in the shared project. These devices are primarily wind turbines, water pumps, and motor loads. The energy-saving effect of using high-voltage frequency converters is very outstanding, usually achieving a power saving of about 30%.
4. Oil and gas drilling and production industry:
Since 2004, the oil and gas drilling and production industry has been in a period of high prosperity, with China's three major oil companies maintaining an increase of over 20% in exploration expenses. Recently, China has made a series of serious resource discoveries in the field of oil and gas, such as the Hebei Jidongnanbao oilfield with a geological reserve of 1 billion tons of crude oil, the Sichuan Longgang gas field with a geological reserve of 500 billion cubic meters, and the 12th district of the Tahe oilfield in Xinjiang with a geological reserve of nearly 200 million tons of crude oil. It is estimated that the investment in oil and gas exploration by major oil companies will continue to improve in the coming years. Frequency converters are mainly used in the oil mining industry, primarily for motors of load types such as oil extraction machines (knocking machines), water injection pumps, submersible pumps, oil transfer pumps, gas compressors, etc., with the aim of energy conservation for motors.
5. Petrochemical industry:
The petrochemical industry is the artery of national economic development. Frequency converters are primarily used in various pumps, compressors, and shared projects in petroleum processing (refining) to achieve energy-saving and process control capabilities.
6. Building materials industry:
The building materials industry is an important information industry in China, and its products include three categories: building materials and products, non-metallic minerals and products, and inorganic non-metallic new materials. The products of frequency converters are mainly used in equipment such as blowers, crushers, belt conveyors, exhaust fans, rotary kilns, etc. in the building materials industry. According to calculations by affiliated organizations, about 70% of China's cement production capacity is in the form of shaft kilns with outdated skills and high energy consumption. Through the transformation of the frequency converter, energy savings of 10% to 20% can be achieved, which can improve the controllability of product quality. According to Dongfang Securities' analysis, the demand for high-voltage frequency converters in the market will continue to grow at a rate of over 40% in the coming years. It is estimated that by 2012, the capacity of China's high-voltage frequency converter market will reach about 8.8 billion yuan, and it is estimated that the capacity of the frequency converter market will exceed 50 billion yuan in the next ten years. The potential of China's high-voltage inverter market is enormous. Currently, the utilization rate of high-voltage inverters in China is less than 30%, while in developed countries it has reached 70% Due to the fact that the installation of a frequency converter can achieve a uniform power saving of 30%, the use of high-voltage frequency converters is accelerated in a low-carbon economic environment. In 2008, the sales revenue of China's high-voltage inverter market reached 3.4 billion yuan, and it is expected to maintain a growth rate of over 40% in the next four years. If only 30% of existing and newly added motors are retrofitted for speed regulation and energy conservation, there will be approximately 70 million KW and 70000 units of shopping mall capacity. In the next ten years, the shopping mall capacity will exceed 70000 units and the output will exceed 50 billion yuan.
7. Coal industry:
La Chine est le premier producteur mondial de charbon. Secteur énergétique fondamental du pays, l'industrie charbonnière a toujours été à forte intensité de main-d'œuvre. Pour la transformer en une industrie à forte intensité de compétences et s'engager sur la voie d'une nouvelle industrialisation, il est nécessaire de promouvoir activement les compétences de haute technologie, d'améliorer la puissance de fonctionnement des équipements et le niveau d'automatisation. La régulation de vitesse par convertisseur de fréquence peut contribuer significativement aux économies d'énergie des treuils utilisés dans les mines. Actuellement, les pays développés utilisent largement les convertisseurs de fréquence pour la régulation de vitesse des convoyeurs à bande, le contrôle de leur démarrage, la régulation de la vitesse des ventilateurs (y compris les ventilateurs d'extraction principaux et secondaires) et la régulation de la vitesse des pompes à eau. Outre l'amélioration de la transmission de la chaleur, l'avantage principal de l'intégration d'un convertisseur de fréquence dans les moteurs de ces équipements est la réduction de la consommation d'énergie.
Il ressort des informations ci-dessus que les convertisseurs de fréquence trouvent de nombreuses applications dans divers secteurs de contrôle industriel et que la demande du marché est très forte. Leur potentiel de développement futur est donc considérable.
