The energy conservation environmental protection requests electrical machinery industry intellectualization Cheng Biyao the tendency


Along with China industry economy’s development, the electrical machinery is obtaining the widespread application. According to the series idea, the electrical machinery system electricity consumption approximately composes the national electricity consumption 60%, its stroke machine uses electricity occupies the national electricity consumption 10.4%, the bike hub motor pump class electrical machinery accounts for 20.9%, the compressor accounts for 9.4%., but is, our country 80% above electrical machinery product efficiency ratio overseas advanced Shui Pingdi 2%-5%, electrical machinery system efficiency ratio overseas advanced Shui Pingdi 10%-20%., therefore, our country is proposing the high electrical machinery system efficiency, the Canadian strong system energy conservation management aspect has greatly must ask.
At present our country electric motor installing equipment aggregate capacity has reached more than 400,000,000 kW, the year power consumption reaches 1,200,000,000,000 kWh, occupies the national total electricity consumption 60%, occupies the industry electricity consumption 80%, in which air blower, the water pump, compressor’s installing equipment aggregate capacity has surpassed 200,000,000 kW, the year power consumption reaches 800,000,000,000 kWh, occupies the national total electricity consumption about 40%, therefore on electric motor’s energy conservation request is enormous, also conserves energy the place which the effect most can manifest. Uses the new electric machine design, the new craft and the new material, through reduces the electromagnetic energy, electric bike motor the heat energy, the mechanical energy loss enhances the output efficiency, conserves energy the electrical machinery high highly effective compared to the tradition electrical efficiency approximately 3%-5%, at present achieves 2 level of energy efficiency target electrical machinery’s occupying compared to insufficient 10%, therefore its growth space is broad.
“Implements the Electrical machinery Energy efficiency Promotion Plan about the Organization (20132015 Years) Notice” proposed that to 2015, realizes the electrical machinery product to turn to a new generation, 50% low pressure three-phase cage type asynchronous motor product, 40% high-tension motor product achieves the highly effective electrical machinery energy efficiency standard standard; The accumulation promotion highly effective electrical machinery 170,000,000 kilowatts, the elimination is using the low efficiency electrical machinery 160,000,000 kilowatts, implements Hub motor the electrical machinery system energy conservation technological transformation 100,000,000 kilowatts, the implementation elimination electrical machinery highly effective makes 20,000,000 kilowatts again. Estimated that in 2015 realized the electricity saving 80,000,000,000 degrees in the past, was equal in conserves energy 26,000,000 tons standard coals, reduced the row of carbon dioxide 68,000,000 tons.
Along with the electric power electronic technology, the computer technology, the microelectronic technology and control theory’s development and the application, the middle and small scale electrical machinery application domain is day by day widespread. In order to realize high quality, highly effective and the low cost movement, the middle and small scale electrical machinery under each kind of different operating mode with the computer, the electrical machinery controller, the power transformer, the sensor and so on many aspects connects, but also often must with the latter level implementing agency and the load (for example each kind of machinery, hydraulic pressure,Electric motorcycle motor pneumatics) the conformity gets up.
Thus, the electrical machinery already was not a spare part level implementing agency, but was one may realize the predetermined function integrity integration of machinery system. On international ABB, Simens, Mitsubishi and so on have developed from the electrical machinery Manufacturing firm for world famous the electrical machinery and the control system Production enterprise, its product scope already from the electrical machinery was a core, extended to motor control domains and so on frequency changer, soft starter, manifested the big technical superiority and the competitive advantage, occupied the big market share. Our country electrical machinery Manufacturing firm started to pay attention to the motor control technology, but must realize the electrical machinery system parameters optimization to match and to control the integration, and promotes the mature product, but must make the difficult Electric bike motor endeavor.
The electrical machinery and system efficiency’s promotion has become one of energy conservation potential biggest industries. On the international various countries’ government and the organization studies the different application domain, the different Industry sector’s various electrical machinery system’s energy conservation plan in abundance, the formulation energy conservation leads, the standard, the laws and regulations, and develops the related green energy conservation product, for example: IEC unifies global the electric motor energy efficiency and the test method standard: Electrical machinery systems and so on European Union’s EuroDEEM, American MMASTER conserve energy the platform; European Union’s ecology design plan and so on.
Our country is impelling and supports the highly effective electrical machinery and the electrical machinery system energy conservation project development and the implementation positively. Highly effective, the ultra highly effective middle and small scale electrical machinery, the velocity modulation special-purpose electrical machinery, developments and the electrical machinery and so on electrical machinery system energy conservation control product research and so on system green energy conservation technology have become potential of brushless motor the development.
At present on the international advanced electrical machinery system integrated functions and so on diagnosis, protection, control, communication, may realize the electrical machinery system’s self-diagnosis, protect oneself, the self-velocity modulation, the remote control and so on. Equips the manufacturing industry along with our country to high, the essence, the sharp direction develops and the industrialization, the informationization two fusions, the electrical machinery system intellectualization develops into the essential tendency.
