摘　　要：文章详述了可调电抗器在电机磁控软启动中的应用,理论和实践证明,通过调节可调电抗器的电抗值,可降低定子电压,将电机启动电流限制在所要求范围内,电机启动平滑,对机械、电网冲击小,提高系统稳定性。In the article, the applications of adjustable electric reactors in soft start of magnetic control for motors are e- laborated in detail. The theories and practices have proved that the stator voltage could be lowered so that the starting cur- rent of motors could be limited within the required range by adjusting the values of reactance for adjustable electric reactors. As a result, the motors could be started smoothly so that the impact to machinery and power grids is small as well as the sta- bility of system could be improved.
