在直流回路过压跳闸后将斩波器和制动电阻投入，结果跳闸更加频繁。变频器操作手册上对直流回路过压原因的解释通常有2点:a)进线电压过高;b)减速时间太短;因该变频器已投入运行2个月，且跳闸时进线电压在允许的范围之内，其它变频器工作正常，结合以前处理变频器故障时对直流回路过压的认识，认为在使用电压控制器调节回馈电流防止直流回路过压的情况下，负载电流的变化率过大是引起过压的一个重要原因，到现场查看被控设备时，发现有一块物料卡在传送带的间隙中，清除后，变频器工作正常。拆开变频器外壳检查，发现制动斩波器上设有三档进线电压选择装置(400V、500V、690V)以适应不同的进线电压，其中短接环插在690V档上。

设计时应根据具体情况通过编程来选择保护功能或使某些保护功能失效。《低压配电设计规范》GB50054-95第4.3.5条规定：“突然断电比过负载造成的损失更大的线路，其过负载保护应作用于信号而不应作用于切断电路。”在前面提到的消防泵控制系统中，由于消防泵是消防应急负荷，它是在消防救火的紧要关头工作的。当火灾发生时，重要的问题是消防泵能地运转打水到消防管网中，而对消防泵电机的保护就不是重要问题。所以上面提到的某些保护功能可以通过编程使它失效，或者使保护动作于信号而不是作于使消防泵电机停机。前面提到的过载保护功能也只应动作于信号。2）支路保护由于软起动器本身没有短路保护，为保护其中的晶闸管，应该采用快速熔断器（自动空气开关的开断时间较长。

软启动器面临的替代压力越来越大，科技进步带来的产品更新换代应该会是一个趋势。这就如同节能灯替代白炽灯一样，这是科技和生活进步的必然结果，变频器替代软启动器也是同样道理。特别是的变频器产业在近十多年的发展中已经实现国产化，国产变频器技术已经比较成熟，制造成本明显下降。软启动器行业从兴旺到衰弱也经历了一个性价比的变革，价格从以前的每千瓦150元降到每千瓦不到50元左右，国内很多企业产品质量非常稳定，但市场在逐渐萎缩。从直起、自耦和星三角启动器的发展演变，到变频调速器的出现，软启动器是这当中的过渡产品。现只有很小部分工况采用软启动器，比如电动机工作负载在90%以上的，其他工况以前是采用软启动方式起动的。

变频器（Variable-frequencyDrive，VFD）是应用变频技术与微电子技术，通过改变电机工作电源频率方式来控制交流电动机的电力控制设备。[1]变频器主要由整流（交流变直流）、滤波、逆变（直流变交流）、制动单元、驱动单元、检测单元微处理单元等组成。变频器靠内部IGBT的开断来调整输出电源的电压和频率，根据电机的实际需要来提供其所需要的电源电压，进而达到节能、调速的目的，另外，变频器还有很多的保护功能，如过流、过压、过载保护等等。随着工业自动化程度的不断提高，变频器也得到了非常广泛的应用。[2]中文名变频器外文名Variable-frequencyDrive、ACDrive简称VFD类别电机控制设备应用变频技术与微电子技术目录1发展历程2变频器组成?主电路?整流器?平波回路?逆变器3功能作用?变频节能?在自动化系统中应用?在提高工艺水平和产品质量方面的应用?实现电机软启动4分类5给定方式6控制方式?正弦脉宽调制(SPWM)控制方式?电压空间矢量(SVPWM)控制方式?矢量控制(VC)方式?直接转矩控制(DTC)方式?矩阵式交—交控制方式7变频器的选用?需要控制的电机及变频器自身?变频器功率的选用?变频器箱体结构的选用?变频器容量的确定?主电源8发展方向?网络智能化?专门化和一体化?节能环保无公害?适应新能源发展历程变频技术诞生背景是交流电机无级调速的广泛需求。
