The development describe of China ELECTRIC MOTOR and system in energy saving technology
Electric motor’s application in the modern society is relatively common. However, motor and its system is in the process of using, because of its energy-saving system not perfect and the electric energy waste phenomenon. Electrical energy waste not only reduce the efficiency of energy utilization, also greatly reduces the overall economic benefits of our country's industry. So, in view of this phenomenon, this article will be the development of energy saving technology of ac motor and its system to conduct a comprehensive analysis and inquiry.
1, Introduces energy saving technology of electric motor and its system
(1) on the analysis of the motor. Electric-motor is an indispensable important equipment of industry in our country, its working principle is: in accordance with the law of electromagnetic induction in physics to achieve energy conversion. Its role is: use electricity to generate torque, and then provide power supply for all kinds of mechanical equipment.
(2) has analyzed the present situation of the motor and system energy conservation. In terms of the current situation, industrial power consumption situation is very serious in our country, such as: in 2013, China's overall industrial electricity consumption reached three 5 of the total generating capacity. And in such a huge power consumption, there is a large portion of the energy loss because the electric motor itself and wasted. The electric energy waste, not only let the plight of our country into a power arid, also caused huge economic loss to our country. So, in order to effectively avoid the occurrence of these phenomena, it is necessary to improve the energy saving technology of motor and its existing system, to make the motors in the process of operation, to minimize power consumption.
(3) the analysis of energy saving technology of motor and its system in our country at present. The content of the motor and its system energy-saving projects mainly has the following five aspects: (1) with the emergence of high-tech technology, more energy saving effect of mechanical equipment has been derived. So, this time should be the enterprises efficiency low mechanical equipment, removed before then in some new and highly efficient mechanical equipment. (2) improve the operation efficiency of the motor and its system. (3) change the operation mode of mechanical equipment itself. (4) improve the overall operation mode of the motor and its system, and real-time monitoring. (5) in the process of motor and its system reform should strengthen the oil industry, electrical and mechanical industry, power industry and coal industry transformation of work.
In general, the establishment of a perfect system of electromechanical and energy-saving projects, that is helpful for the whole industry. Because it not only can effectively improve the present situation of industrial electric energy waste in China, will also be able to further improve the level of the overall development of China's industry.
2, To explore the development of motor and system in energy saving technology
(1) Try to analysis the development of variable frequency speed regulation and energy saving technology.
Speed of the electric motors drive can be divided into two kinds: dc and ac. And now, in the ac speed regulation of motor application of energy-saving technology is the most widely variable frequency speed regulation and energy saving technology. The advantages of energy saving technology has four, they are: (1), allowed to drive motor speed to keep in the running state of a relatively stable (2) make motor drive can be infinitely adjustable-speed operation process and system (3) improve the motor startup ability is greatly decreased (4) motor and its current needed for system boot. It is because the frequency control of motor speed and energy saving technology has these advantages, so it is in the motor and its energy efficiency of the system is has a significant effect. And the ordinary frequency control of motor speed technology is only a single want to control speed, it on the motor and its system does not play any role in energy saving. Then, the frequency control of motor speed and energy saving technology and applied to the motor system, is the less waste and its system can effectively improve motor electric status quo.
(2) "no-load step-down" energy saving technology. In the whole process of the motor running, the electric motors did not achieve full load operation, most of the time but at the moment of voltage are always under a high state. In this way, will not only make the whole system fall into a state of overload, also will be more electric power is wasted. So, in order to effectively improve the phenomenon, will "no-load step-down" energy saving technology is applied to the motor and its system.
The principle of "no-load step-down" energy saving technology is: when there is light load or no-load motor, according to the actual operation situation of the motor to the appropriate voltage adjustment. At the same time, the power consumed by a stator iron will also make the corresponding changes with the change of the voltage. In this way, can largely reduce the power loss of the stator iron.
Above all, energy conservation of the motor and its system is the premise condition of industry in our country can realize high-efficiency operation. If the energy saving effect of the motor and its system is the country did not meet the requirements, this makes the motor in the process of actual operation, and wasted a lot of electricity. So, in order to effectively reduce the amount of waste of electricity, motor and its system in order to improve the overall development of China's industrial level, also have to set up a perfect motor and system energy conservation projects.
