软起动器在液压系统的应用及研究

Application and Research of Soft Starter in Hydraulic System

随着传动控制对自动化程度要求越来越高和电力电子技术的迅速发展,软起动器地应用也越来越广泛。软起动器是一种集软起动、软停车、轻载节能和多功能保护于一体的电机控制装置。它不仅在起动过程中能够无冲击而平滑的起动电机,而且能根据电动机负载的特性来调节起动过程中的参数,如限流值、起停时间等,达到最佳的起、停状态。同时,它还具有过载、过热、缺相等多种保护功能,从根本上解决了传统的降压起动等许多弊端。

With the development of power electronics technology,the application of soft starter is more and more extensive.Soft starter is a motor control device that integrates soft starting,soft stopping,light load energy saving and multi-function protection.It can not only start the motor without shock and smoothly,but also adjust the parameters in the starting process according to the characteristics of the motor load,such as current limit value,start and stop time,etc.,to achieve the best start and stop state.At the same time,it also has overload,overheating,open-phase protection functions,solve the problem of traditional reduced voltage start.
