China Energy-saving Frequency Converter Begins to Accelerate Growth

Inverter is the development direction of electrical energy. Inverter is the first use of speed control, as technology development and social requirements for energy efficiency in the use of the rising gradually for energy conservation. With speed and high precision frequency control, start low energy consumption, can realize stepless speed regulation, easy operation, versatility, etc., is considered the best AC motor speed control program.

Market has great potential and broad application prospect. In China, fans, pumps, air compressors and other power equipment to meet the power requirements to run the highest output power often have great design redundancy. In the absence of Frequency Control of the case, generally through the valve, damper adjustable output power and other equipment required to meet the load changes, the output of energy is wasted on a large number of valves and throttle bezel.

In the case of using the inverter, these devices can be based on the actual load requirements by adjusting the motor speed to adjust the output power to the motor output of energy used efficiently. After using the converter of industrial enterprises, help to adjust the motor speed, optimized production technology, can achieve significant energy saving effect, widely used in lifting machinery, textile and chemical fiber, oil and gas drilling, metallurgical, petrochemical and chemical, coal, building materials , municipal and other industries.

Frequency Control System obvious economic value of energy conservation. According to the survey, our inverter market for at least 10 years before this becomes saturated, the overall market potential for the 120 billion to 180 billion yuan. According to the current average of about 800 kW high voltage inverter price estimate does not consider future additional demand for high voltage motor speed regulation, high-voltage inverter potential market as high as 81.2 billion yuan.

Inverter industry in China from 2000 to 2008 the average annual growth rate of market capacity for more than 15%. 2008 China’s low-voltage inverter in the market capacity of about 11.18 billion yuan, of which low-voltage inverter 97.7 billion, the pressure transducer was 14.1 billion, compared with 2007 is still growing, but due to the financial crisis by speed slowed down. With the economic recovery, the gradual promotion of electrical energy and identity, and it starts to accelerate future growth.

High voltage inverter market in China has maintained a high growth rate. From 2005 to 2008 the average annual compound growth rate of 40%, in 2008 China’s high-voltage inverter market sales of 34 billion yuan, grew by 47.8%, in 2009 the high-voltage inverter market growth will be smaller than in 2008 a certain decline, from 2009 to 2012 the annual market growth rate will remain at 40%. According to market statistics over the past few years, we have the next four years in the low voltage inverter market capacity in China was estimated: By 2012, China’s market capacity in the low voltage inverter more than 19 billion yuan, of which more than 160 low-voltage inverter market capacity billion, medium voltage inverter market capacity of more than 3.0 billion.

Compared to foreign markets, high-voltage inverter industry in China started late. Before 2004, foreign brands a virtual monopoly on the domestic market, high-voltage inverter. But after 2004, domestic manufacturers of quality performance products is close to or reach the level of similar foreign products. Currently, domestic enterprises completely dominated, with 80% market share. As the domestic brands through price and service advantages to seize the most common high-voltage inverter market share, Siemens, ABB and other foreign brands have gradually from general-purpose high-voltage inverter market contraction, to a focus on Technical Barriers to higher, more profitable high performance of high voltage inverter market.
