中压交流电机软启动技术问题探讨

Probe into technical problem of soft start for mid-voltage AC motor

针对中压大功率交流电机软启动器的工作特点,对装置主电路及保护参数、高压脉冲电源、脉冲触发方式及软启动软停机控制中的一些问题进行了分析讨论,提出合理实施意见。

Based on the working characteristics of soft starter for mid-voltage & high power AC motor, analysis and discussions aremade to the main circuit, protection parameters, high voltage pulse supply, pulse trigger mode and the control problems in soft start & softstop. Feasible and practical proposals are put forward.
