【摘要】 介绍一种由乌克兰“汉姆斯”引进的高压同步电动机的变频起动装置。该装置采用磁场定向的矢量控制原理，对高压同步电动机实现变频起动，可大幅度降低电机起动电流和功率，减小网上容量，降低机械冲击。使起动过程平滑、起动时间可调。在几个大型钢厂使用，效果很好。更多还原

【Abstract】 The paper introduces principle and application of variable frequency starting system of high voltage synchronous motor by UKL "Khemz" import. It has the features that starting current is small, starting pro-cess is smooth and starting time can be adjusted. The starting power is far srnaller than rate power.更多还原
