High voltage converter has remarkable energy saving effect. Without changing the main engine equipment, the average energy saving rate can be achieved by changing the speed only, among which the average energy saving rate of petroleum system is 38%, that of petrochemical system is 46%, that of metallurgical system is 42%, that of urban water supply and drainage system is 45% and that of chemical system is 24%. The total installed capacity of the fan, water pump and compressor system in China is about 160 million kw, and the annual power consumption is nearly 500 billion KWH. By changing the adjustment mode, the system can save 10 ~ 15% of the power, which is about 50 billion ~ 70 billion KWH. From the speed regulation effect, frequency conversion speed regulation technology is the best speed regulation technology, its speed range is the widest, can reach 100% ~ 5%, speed regulation accuracy is the highest, can reach ±0.5%. Therefore, driven by the policy of energy conservation and emission reduction, the domestic high voltage inverter market will continue to show a high growth trend.
Under the huge market demand stimulation, our country high voltage inverter market growth speed is rapid. In 2005, the market size of high-voltage inverter was about 1.09 billion yuan, while in 2008 it had reached 3.4 billion yuan, with a compound growth rate of over 40%. According to the 2009 China High Voltage Frequency Converter Market Research Report, the market scale of China high voltage frequency converter will reach 15 billion yuan in 2012, and the market growth rate in the next few years will remain at a high level of more than 40%.
An expert in the field of frequency conversion in China said: The motor system energy conservation projects in the top ten key energy conservation projects will have corresponding hard targets every year, which will certainly stimulate the demand for high-voltage frequency converter, although there is a recession in the short term, in the long run, the market potential is huge, broad application prospects. The inverter market in China will be saturated for at least 10 years, and the total market potential is 120 billion yuan to 180 billion yuan. According to the current price estimate of about 800 yuan per kW high voltage frequency converter, the potential market of high voltage frequency converter is as high as 81.2 billion yuan, and the application prospect is broad. Frequency converter industry from 2000 to 2008 the average annual growth rate of market capacity in more than 15%.
Some research points out that by 2012, the market capacity of high voltage inverter in China is expected to reach about 8.8 billion yuan. The huge market space has attracted the attention of all sides naturally, according to the incomplete estimate at present the domestic high voltage inverter market main manufacturer has more than 20. Domestic brands have developed rapidly. In recent years, a large number of enterprises with obvious competitive advantages have emerged, such as Lidflafu, Hekang Yisheng and Rongxin Group. At present, the market share of domestic brands has exceeded 50%.
High voltage inverter market demand is still very large, but foreign enterprises have been the first, to break the foreign enterprises in high power, super power high voltage converter monopoly, is now the focus of the development of domestic electrical enterprises. The power devices used in the high voltage frequency converter have always been the bottleneck of the development of high voltage frequency converter technology in China.
