Familiar with China's high-voltage inverter industry, in 2006 2007, the market blowout and fierce competition is impressive, with increased support for the maturity of the market and the state, industry insiders believe that in 2008 the market will enter the golden period of high voltage inverter stable growth.
However, the global financial crisis, electric power, metallurgy and other industrial growth slowed down or even stagnation, people have to adjust to market expectations of high voltage inverter industry, the pattern is undergoing new changes.
High growth stopped abruptly
According to the China Electrical Equipment Industry Association branch statistics, in 2007 the amount of high voltage inverter contract reached 1 billion 650 million yuan, an increase of 61.8%. As for the market situation in 2008, Zhao Xiangbin, Secretary General of the frequency converter branch, told reporters that the current situation of the development of the market statistics and research work in progress, it is not convenient to disclose the relevant information.
Nevertheless, the high-voltage inverter companies have felt the changes in the market. Beijing Edward Fu electrical technology limited company experienced a sustained increase of 8 the previous month in 2008 of September, the market suddenly turned, a marked decline in sales growth; Beijing hiconics Technology Co. Ltd. from December 2008 began, obviously felt less demand than in previous years.
A high energy consuming industry with a close contact with the China Energy Conservation Association, told reporters: by the economic crisis, the domestic electricity, metallurgy and other industrial development is slow, downward pressure on profit margins gradually increased." In the power industry as an example, in 2008 1 to November, the national electricity consumption, showing the monthly growth rate accelerated decline trend, October, November is a continuous negative growth, the national electricity appeared in history has been a big turning point. From the CLP announced the cumulative average utilization hours of power generation equipment from 1 to October, China's power generation hours of H, has broken the lowest point of history of 4800 H.
Electric power, metallurgy and other large industrial users are mostly state-owned enterprises, has been mainly through energy-saving transformation to achieve their commitment to the country's energy efficiency indicators. However, in the case of production decline, they may consider delaying or canceling the procurement of energy-saving equipment. As one of the main industrial energy-saving equipment, high voltage inverter bear the brunt." China Energy Conservation Association said. It is understood that China's high voltage inverter in the industrial field is mainly used in fan and water pump start or variable speed, to improve the power, reduce energy consumption, especially the motor energy saving effect is very significant, is the main means to realize energy saving and emission reduction of industrial users.
Although China's energy situation is still grim will boost on 2009 high voltage inverter market, but these people also expressed their concerns about the economic crisis made the whole industrial production slowdown, high consumption and low efficiency in the first enterprise to be eliminated, which may have a positive effect to achieve the goal of energy saving and emission reduction in China, but from another point of view, the economic crisis has also reduced the desire for energy saving companies."
Market transformation does not turn
Different from the traditional market cooling, the state's investment in energy-saving emission reduction does not fall. The day before the national development and Reform Commission announced that the central government will add 100 billion yuan investment from the budget allocated 2 billion 500 million yuan earmarked for the ten major energy conservation projects, recycling economy and industrial pollution in key drainage treatment project construction.
The "ten key energy-saving projects in the motor system energy-saving projects every year the corresponding indexes, which will stimulate the demand of high voltage inverter, although the short-term decline, the long term, the market will not change the direction of development." An expert in the field of domestic high voltage inverter.
In addition, with the start of stimulating domestic demand policy, to build wind power construction of the Three Gorges and the construction of high-speed rail trillion funds, but also provides a new market demand for high voltage inverter.
The excitation converter is mainly used in the direct wind or double fed type terminal. As domestic products are still under development, so the market is mainly imported products. It is noteworthy that the State Ministry of science and technology has set up a special support for wind power project plan, the establishment of the 30 wind power research projects, there are 6 projects related to the inverter, is brewing a major breakthrough." The expert said, on the other hand, high-speed rail inverter products in the field is mainly 1~3.3 kV, precision control requirements are also very high, so it is mainly dependent on imported products."
There are few domestic enterprises to get involved in the emerging field, and even today the potential for a period of time is very large, but the technical threshold is high, becoming the biggest bottleneck for domestic enterprises to enjoy the market feast. "Emerging markets will face more challenges in technology. Such as vehicle power supply, high demand against vibration, voltage fluctuations and other special considerations should also be considered; wind power on the environment is more demanding, but also to achieve self inspection, adaptive remote automatic control system." Tianjin Electric Drive Design Institute of product development department chief engineer surnamed Wu told reporters, "the domestic high voltage inverter companies should take advantage of its production period, will focus more on research and development, technical reserves, waiting for the market to pick up or when opportunities arise to have enough strength in."
Technological innovation "does not slack off"
Through technological innovation across the threshold of the market, is China's high voltage inverter business "glorious tradition". Domestic enterprises from the introduction of imitation, through independent research and development, and constantly realize the innovation of intellectual property rights, and again and again to narrow the gap between foreign products and technology. Even in the recession of 2008, high voltage inverter industry in the field of technology has also made a lot of sudden
