Chinese and foreign brands compete in the domestic market
Not long ago, the Beijing Times Electric Co., Ltd. Jinneng independent research and development of new high-voltage large-capacity inverter Restime series obtained Innovation Competition Award Sixth Beijing invention. Allegedly, this has successfully developed products with independent intellectual property, so that China's large-capacity inverter technology is a world leader.
Researchers CCID investment adviser, told reporters that the domestic brands in the high-voltage inverter market has been firmly occupy a dominant position, but in the field of low-voltage inverter is still lost to foreign brands.
Huatai Securities Research believes that different in the low frequency and high voltage inverter prices accounted for the proportion of complete sets of equipment, resulting in a competition of two industry segments differentiated. Since the cost of high voltage inverter accounted for a higher proportion of complete sets of equipment, so the downstream enterprises are more sensitive to prices, which also led to cost-known domestic brands accounted for 80% of market share. The proportion of low and medium voltage variable frequency equipment prices lower, but its high performance requirements, so the downstream enterprises pay more attention to the use of the effect of the product.
It is understood that the domestic inverter market entry of foreign brands is the originator, foreign brand market share reached 70%. ABB, Siemens, Fuji Electric, Mitsubishi Electric, Yaskawa Electric, Schneider, Emerson and other foreign brands occupy the lion's share of the low-voltage inverter market. Domestic brands Shenzhen INVT places, Chengdu hope Shankland, Shenzhen Kymmene technology represented.With the upgrading of the status of the energy industry, the potential capacity of the inverter market has attracted many industry participants. According to statistics, the number of brands on the domestic inverter market more than 100, in addition, there are thousands of agents engaged in product sales and secondary development of the company.
Related statistics show that, at present, the domestic market, the growth rate of the inverter installed capacity of about 20 percent, according to the needs of this market development speed and to calculate, need about 10 years time, the inverter market to saturation.
Industrial energy efficiency by strong pull
According to reports, the initial purpose is to drive the speed control, along with the development of technology and society for increasing the use of energy efficiency requirements, gradually being used in the field of energy. Today, the inverter is the development direction of motor energy.
China's industrial energy industry CCID investment adviser provides investment and financing and M & Strategic Studies (2012) showed, according to the estimates, the drive motor system using common energy-saving rate of about 30%, in some places up to 40% higher -60% energy saving effect is very significant.
A coal equipment Enterprises official told reporters, mixing as a strength of electrical, mechanical and electrical integrated technology, the development of frequency control in recent years, the ongoing modernization of coal enterprises productive and efficient construction provides a good opportunity.
According to reports, frequency control technology for the coal industry is earlier mine hoist, currently widely used in developed countries have the drive belt conveyor belt conveyor speed or start control, fan speed (including primary fans and local fan) and pump speed. Inverter is used in addition to the above equipment to improve transmission performance, the more important is that you can save energy.
Electric power industry, energy, emissions, energy situation is even more grim. Because of the frequency converter can efficiently save energy in many industries, improve the technological level, and therefore, to some extent, reduce the drive to promote the application in various industries can reduce the amount of electricity power industry pressure indicators, while saving energy emissions , reducing energy consumption.
"On the other hand, is one of the important applications of power converter products industry from thermal power plants in our country associated with the inverter control process, the transmission of wind, coal, water, slag and exhaust systems are suitable for medium and low voltage inverter applications. "Beijing a technical responsible person said inverter manufacturers.
In addition, the reporter also learned that in the petrochemical industry, the drive is mainly used in various types of pumps, compressors and public works, in order to achieve the purpose of controlling the level of technology. At present, the inverter products in China's petrochemical industry assembly rate is not high, a huge potential for development.
Core device battle started
2011, the domestic market demand in low-voltage inverter, first appeared faster than the growth rate of the phenomenon of high-voltage inverter, high-voltage inverter is further intensified competition. "Normally, an increase in low-voltage inverter market size in 10% -15% level, but in 2011 the growth rate for the first time exceeded the high voltage inverter, reaching 30% of accelerated development," industry sources said.
Overall, our late start frequency control technology, compared to Europe, Japan and other countries sent to late 10-15 years. However, some experts believe that due to the current high-end inverter market applications are mainly occupied Europe, Japan brand, in terms of the long-term trends, nearly 80% of the import substitution space, low pressure will drive the future in the battle.
In recent years, with the core of the development of the inverter electronics industry, the drive from the initial SCR (thyristor), GTO (gate turn-off thyristor), after a BJT (bipolar power transistors), SITH (SITH ), MGT (MOS control transistor), MCT (MOS controlled thyristor), the development of today's IGBT (insulated gate bipolar transistor), HVIGBT (high voltage insulated Gate Bipolar transistor), led the drive to update the device application broader areas, along with the rapid expansion of market scale.
It is understood, IGBT case of microelectronic products, currently in the field of technology is relatively backward, domestic inverter enterprises generally used in Germany and Japan imported products. Medium and low voltage inverter needed for the production of IGBT, only a small number of domestic enterprises can supply.
"In the future, the inverter market competition is to develop the ability to compete for the core device IGBT, which is the effort to break through on the IGBT demand reasons." Shenzhen, a company official said inverter reporters.
