In recent years, around the “shortage intensified this year comes early to late summer peak has passed, but the electricity shortage is still a long time does not leave people in the industry predicted, the” shortage “in China will become the norm.
According to the department published data, since the second quarter of this year, the Guangdong power shortfall of more than 5 million kilowatts, Shenzhen power shortfall of more than 1 million kilowatts, Guangxi is the plight of the most severe power shortage in the encounter 20 years ago, thousands of businesses were forced to stop production, Sichuan, Chongqing, Guizhou, Yunnan, Hainan, Jiangxi, Zhejiang and other southern provinces are the power shortage situation. According to the statistics of the China Southern Power Grid, the maximum peak shifting the load of the Southern Power Grid in August reached 11.2 million kilowatts, even in September and October, the China Southern Power Grid is still the overall lack of electricity for more than 8 percent, individual regional power shortage for more than 20%.
Increasingly serious “shortage” phenomenon with the southern provinces and cities in China, energy-efficient Electrical Equipment & Supplies in this process reveals its important position, limited by the power shortage in the enterprise potential increasing demand for energy-efficient electrical equipment.
As an important driving force of industrial production aspects of the energy efficient motor will effectively improve the energy issues, the experts believe, for the motor industry, the “shortage” will be the opportunity for market growth of energy-saving motors.
A number of advantages
Motor as the power source for fans, pumps, compressors and other equipment, widely used in industry, agriculture, transportation and other fields. According to statistics, the power consumption of the motor in the country’s total electricity consumption accounts for a sizeable proportion of industrial electricity consumption, electricity consumption accounted for about 66%, accounting for about 50 percent of the country’s total electricity consumption. So the industry, industrial energy efficiency must improve the efficient motor start.
According to experts, energy-saving motors with new design ideas, new technology and new materials, to improve output efficiency by reducing the electromagnetic energy, thermal and mechanical energy loss. Compared with standard motors, the use of energy-saving motor energy saving effect is very obvious, under normal circumstances efficiency can be increased by 4%.
First, high efficiency, energy saving. Compared with ordinary motor, the energy-saving motors through the use of quality materials and the optimization design, their design tends to give more consideration to the factors such as the motor iron loss loss, etc., in terms of materials, core materials commonly used silicon steel, while high-performance iron chip insulation coating technology to use one of its energy consumption fell by an average of about 20%.
The longer run, energy-saving effect is more obvious, the higher the product of economic For businesses, you want to obtain the recovery of funds in the fixed capital investment, a shorter useful life, high efficiency motor advantage in this regard is self-evident. According to statistics, a 45 kW motor efficiency by 1 percent, saving nearly 4000 kwh per year, while the energy-saving motors than ordinary motor efficiency increased by about 4%, generally 1 to 3 years to recover the investment of all the updated motor .
Third, long life, high reliability equipment. This is because the energy-saving motors to take a design to reduce losses, the temperature coefficient is small. Prices of energy-saving motors as compared with ordinary motor 15% to 30% more expensive, in general, energy-saving motors is higher than General Motors of investment can be recovered in a shorter useful life, throughout the life cycle, available for businesses to save electricity.
The fourth is to greatly reduce environmental pollution. The information shows that in 1997, the United Kingdom throughout the industry’s total energy consumption of 104,455 to one million kilowatts hours. Among them, only the motor consumption accounted for 65% (about 678 965 million kilowatt-hours). If the motor efficiency can be increased by 2% a year can save 135 million kilowatts hours of electricity, if the calculation of consumption of one kilowatt hour of electricity produces 0.57 kg of carbon dioxide, reduce emissions to the atmosphere 75 million tons a year carbon dioxide.
Worrying situation
According to statistics, over the years the motor power consumption in China accounted for 66 percent of the country’s power consumption, of which about 35% of the power consumption of the small three asynchronous motor is the power-hungry. According to the national small and medium-sized motors Quality Supervision and Inspection Center on a sample survey of 198 domestic key enterprises motor, which reached more than two of the proportion of energy-saving motors only 8%. This is a great waste of resources of the community as a whole.
On the contrary, the status of very low and the proportion of domestic energy-saving motors applications In recent years, the export of domestic small and medium-sized energy-saving motors showing the rapid trend of substantially year after year increments. Exports only $ 327 million from 2000, exports reached $ 1.633 billion in 2006, then 2010 is about the exports of 2.24 billion yuan.
Compared with the the fiery export of energy-saving motors sold on the domestic market of small and medium-sized induction motor is only reached EFF2 efficiency levels in Europe are very few products, energy-saving motors, and enterprises for the production of energy-saving motors less than one percent of Energy-saving motors market share of only about 5%.
In domestic energy-saving motors can only be exported to foreign and domestic products with high power consumption. It can be seen to promote the use of energy-saving motors, China and Europe and the United States and other developed countries there is a big gap. Why the energy-saving motors “wall flower wall red”?
First of all, most domestic enterprises and government agencies, lack of awareness of energy saving and environmental protection in the purchase of the motor in cost as the main factors to select products, energy-saving motors due to the use of raw materials more than the price above the normal motor 15 % to 30%, which resulted in businesses and government agencies tend to buy the ordinary motor.
Second, the importance of energy efficiency do not understand the motor life-cycle cost of the composition and motor, the same cause the motor to buy, there are errors, and only consider the initial cost to buy the motor, rather than on motor life cycle and its subsequent benefits, this concept largely makes energy-saving motors popularity of the road is quite difficult.
The experts pointed out that, to promote wide popularization and application of energy-saving motors in China, but also from a number of ways to proceed, not only necessary for the state’s policy to support the production, sales, procurement, and also the need for national environmental knowledge and education.
Seize the opportunity
The energy-saving motors were praised, has become a major concern. Experts believe that with the increasingly tough energy saving policies, the “12th Five-Year” period, in support of relevant national policies, the promotion and application of energy-saving motors bound to substantive progress.
National Standardization Management Committee in 2006 issued the mandatory standards for small and medium-sized three-phase asynchronous motor energy efficiency of limited value and energy-saving evaluation, since July 1, 2011, the regulations prohibit the sale of three energy-efficiency motor. This mandatory standard indicates that the energy-saving motors will fully replace the traditional inefficient motors.
On July 26 this year, the introduction of the notification of the Ministry of Finance, National Development and Reform Commission to promote the implementation details on the issuance of the energy-saving products that benefit the project “High Efficiency Motors”. “Notice” provisions of primary and secondary energy efficiency rating for the rated power of 0.55 kilowatts (inclusive) to 315 kilowatts (inclusive) of the low-voltage three-phase induction motor, to give 15 to 40 yuan subsidy per kilowatt; on the loss than the current prospective into the standard 20% rated power of 355 kilowatts (inclusive) to 25 000 kilowatts (inclusive) the high-pressure three-phase asynchronous motor, giving a 12 yuan subsidy per kilowatt; the rated power of 0.55 kilowatts (inclusive) to 315 kilowatts (inclusive) permanent magnet motor, giving a subsidy of 40 to 60 yuan per kilowatt; also released the third installment of “energy-saving products that benefit the project” High Efficiency Motors promotion directory, and electrical products have a total of 9896 models of the 34 companies short-listed in that directory.
The industry believes that the next two years, energy-saving motors account for the proportion of new small and medium-sized domestic motor will reach more than 60% of the energy-saving motors market will reach 48 billion to 57.6 billion yuan.
It should be said that the “shortage” in large part burns our economy, but the double promotion of mandatory energy saving measures and support policies, the motor industry is undoubtedly usher in a good opportunity. In order to seize this opportunity, the motor industry must strengthen energy-efficiency technology and innovation, so that the entire energy-saving motors production processes in the development process, the “shortage” really play the role of basic industry, driven by sustained, healthy development.
