摘要: 随着大型同步电机的广泛应用,高压变频软起动装置越来越来广泛的应用于大型电机的起动中,本文以某钢厂27 MW高压同步电机一拖二变频软起动项目为例,介绍了变频软起动技术在大功率高压同步电机中的应用,应用表明高压同步电机采用变频软起动装置时,起动电流小于电机额定电流,旁路运行投切过程平稳无冲击,操作简单使用方便。
Abstract: With the wide application of the large synchronous machines, the variable frequency soft starter is more and more widely used in starting of them. Taking an iron & steel company’s 27 MW high-voltage synchronous motor using the variable frequency soft starter as an example, this paper introduces the variable frequency soft start technology in the application of the large synchronous motor. It is shown that when the large synchronous motor is started by the variable frequency soft starter, the starting current is less than the motor rated current, the bypass operation process is smooth and steady, and the operation is simple and easy to use.
