摘要
为了能安全合理地应用异步电动机串级调速的方法,从串级调速系统装置的电压和容量、系统效率、系统功率因数,分析了串级调速系统性能。表明了串级调速方式适合的场合和该系统存在的缺点及改善措施。
Reasonably apply a difference step for the sake of the ability safety the electric motor string class adjusts speed of method, the power factor of the efficiency, system of electric voltage and capacity, adjust speed system equipe from the string class, analyzed string class to adjust speed system function.Express the string class adjusts soon the way suits of the situation is with the weakness and improvement measure of the system existence.
