摘要:

电动机节能对纺织业提高自身经济效益作用突出。为此概述了异步电动机在轻载状态下降压节能的原理,分析端电压变化对转子转速的影响,并对电动机稳压节能装置的原理及控制做了简要说明。将稳压装置用于纺织用异步电动机进行数值仿真,研究电动机输入电压、转速、有功消耗等电气量的相关变化及其对节能效果的影响。在电动机节能运行的基础上,综合考虑转速降低对生产效率的影响,并对纺织企业如何提高经济收益进行了探讨。

Abstract:

Energy saving of electric motor is an important factor for the improvement of economic returns in textile industry. In this paper, the principle of voltage reduction and energy saving of asynchronous motor under light-load condition is discussed and the effect of the change of end voltage on the speed of rotor is analyzed, along with brief description of the mechanism and operation of the voltage stabilizing and energy saving system of the motor. Digital Simulation of asynchronous motor equipped with stablizer used for twisters is performed and the effect on energy saving is investigated with a function of input voltage, rotation speed, power consumption of the motor. When the motor is running on the basis of energy saving, the influence of reduction of rotating speed on productivity should be considered. The methods for the textile industry to enhance its economic returns have been investigated.
