摘要
通过讨论三相异步电动机的效率和功率因数与负载率和电压的关系,对调压节能的基本原理和经济效益进行了较全面的分析,并通过实验验证。定量分析了轻载电动机调压节能的可能性。为如何调节电压提供了理论依据。
According to the basic theory of three phase asynchronous motor and through dis-
cussing the relationship between the efficiency, the voltage and the load rate, and the
relationship between the power factor, the voltage and the load rate of three phase asyn-
chronous motor, this article analyses the basic theory and economical benefit of saving
energy with regulating voltage and testifies themselves with experiments in all-round
way. Thereby, it is of the quantitative analysis of the feasibility of saving energy with
regulating voltage about the light-loaded motor. Furthermore it provides the theoreti-
cal fundamentals for the way of how to regulate voltage.
