With the expansion of the market and the diversification of user demand, the functions of inverter products in the domestic market have been continuously improved, the degree of integration and systematization is getting higher and higher, and the operation is more convenient, and special inverter products in some industries have also appeared. In addition, the application field of frequency converters is also expanding. から 工場's 生産 そして 加工 設備 へ 中央 空気 調整, から 重い 機械 へ 繊維 産業, から 0}.4KW 小 電力 へ 20000KW 高出力 モーター 持っている されている されている 広く 中古, そして 明白 経済的 利点 持っている されている 達成
高 電圧 周波数 コンバーター
Due to the wide range of applications, high-voltage inverter speed regulation has become the mainstream speed regulation method of high-voltage AC motor, the actual power-saving effect range is between 20%-60%, acringing to the current average price of about 600 yuan per kW high-voltage inverter, regardless of the future new high-voltage motor frequency conversion speed regulation needs, the potential market of 高電圧 インバーター IS AS 高 AS 80 10億 元, of which 市場 容量 of 高性能 製品 is 約 10 10 10億元. In addition, China's installed motor capacity is still. increase. It is imperative to improve efficiency and tap the energy-saving potential of the motor itself, and the high-voltage variable frequency speed regulation technology has broad prospects.
At present, the situation of medium and high voltage inverters configured with medium and high voltage motors for domestic fan pumps is low, estimated to be less than 20%, and process improvement requirements and energy-saving requirements will exist in China for a long time, which will support the long-term prosperity of the high voltage inverter market. With the increasing importance of environmental protection issues and the continuous improvement of industrial production requirements, the demand for high-voltage inverter products will continue to strengthen, and the high-voltage inverter market is still expected to maintain long-term rapid growth. According to China's transmission network forecast, for emerging markets such as wind power, rail transit, and photovoltaics, the average growth rate of high-voltage inverters can reach 25%, and the local growth rate can reach 30% or even higher; For petrochemical, chemical and other industries, the growth rate is 15-25% on average; For industries such as steel, building materials and power, the growth rate has slowed down.
ミディアム および ロー 電圧 周波数 変換
At present, the users of domestic medium and low voltage inverter products are mainly domestic users, distributed in many economic fields, such as lifting machinery, municipal, coal, oil and gas drilling and mining, petrochemical, electric power, metallurgy, textile and chemical fiber, food and beverage industry, etc. しかし the products of individual excellent brands are exported abroad, the export proportion of the entire industry is still very limited on the whole. foreign brands in China's high-end market of medium and low voltage inverters still dominate, represented by ABB, Siemens and Yaskawa, and their business is mainly concentrated in steel, cement, lifting and elevator industries.
防爆 周波数 コンバーター
At present, China's frequency conversion technology has developed rapidly, but the explosion-proof frequency conversion speed regulation device used in flammable and explosive environments such as coal mines, petroleum and chemical industry has not been effective promoted. At present, only 約 10}% of all kinds of motors used in coal mines are equipped with 防爆 周波数 コンバーター, and acroling に the requirements of the country to save energy and reduce the energy consumption of tons of coal, more than 50% of the motors will achieve frequency conversion control in the next ten years. Aclying to the preliminary forecast of market research, China needs to use such products (1.0-15},000 units) every year, and the equipment that needs to be updated and transformed reaches 0.8-15},000 units, and the market demand is very large.
