软起动与传统减压起动方式的不同之处在哪里。笼型电机传统的减压起动方式有Y-q起动、自耦减压起动、电抗器起动等。这些起动方式都属于有级减压起动，存在明显缺点，即起动过程中出现二次冲击电流。软起动与传统减压起动方式的不同之处是：⑴无冲击电流。西门子模块代理商|云浮PLC模块代理商
FPGA一般来说比ASIC(*集成芯片）的速度要慢，无法完成复杂的设计，消耗更多的电能。他们也有很多的优点比如可以*成品，可以被修改来改正程序中的错误和*便宜的造价。厂商也可能会提供便宜的编辑能力差的，部界面后，一旦其内部开发完成后，其他的设计就可以直接调用这个实体。
在此向学院工程系的全体老师表示由衷的谢意。近年来，随着微电子技术及1GBT功率器件的迅速发展，作为交流电机主要调速方式的变频调速技术也获得了**的发展。尤其是矢量控制变频器，以其优异的控制性能在调速领域*树一帜，在机械、冶金、造纸、电梯等多个领域得到迅速推广。西门子模块代理商|云浮PLC模块代理商
我们在信号系统中大多使用PLC处理接口信息，在设计过程中要尽量将接口信息容易识别，这样在出现故障时，能够尽快判断故障的归属方，便于地铁的运营管理。分析故障或处理故障时也要注意系统性，要综合的考虑系统的各个输入输出才能能准确地判断故障点。
当时，国内鼠笼型异步电动机一般采用直接启动，或用自耦、星三角启动器启动。上世纪九十年代，以单片机为**、半导体可控硅为执行元件的智能化电机软启动器进入中国市场，并在2000年以后开始加速发展，目前市场规模约为20亿。Motors/gearunits and connection systems from Siemens Product Partners

变频器世西门子模块代理商|云浮PLC模块代理商界,2009,(04).变频器应用技术论文篇二变频调速技术应用问题研究，摘要：随着工业自动化程度的不断提高和能源全球性短缺,变频器越来越广泛地应用在冶金、机械、石油、化工、纺织、造纸、食品等各个行业以及风机、水泵等节能场合,并**了显著的经济效益。
其缺点是，由于不限流，在电机起动过程中，有时要产生较大的冲击电流使晶闸管损坏，对电网影响较大，实际很少应用。折叠斜坡恒流软起动这种起动方式是在电动机起动的初始阶段起动电流逐渐增加，当电流达到预先所设定的值后保持恒定（t1至t2阶段），直至起动完毕。西门子模块代理商|云浮PLC模块代理商到世纪之交时期，我国经济实力已有较大的发展，生产手段和生产工具亦有了较大发展，电机容量也有了很大增长，人们开始不满足液态起动装置的低性能，于是晶闸管串联式(固态)软起动装置的应用开始增加，继而又出现了开关变压器式软起动装置和磁饱和电抗器式(磁控)起动装置，变频装置用于电机软起动的情况也越来越多，当前。西门子模块代理商|云浮PLC模块代理商从工作原理上看，软驱动器实际上是--个调压器，输出只改变电压，并没有改变频率。这-点与变频器不同。4)、可以频繁的启动电动机，软启动允许10次/小时，而不致电动机过热。(笼型电动机传统的减压起动方式有:Y-△起动、自耦减压起动、电抗器起动等，皆属于有级减压起动，其缺点是在起动过程中会出现二次冲击电流。
目前，国内外的电机软启动器控制系统一般都采用1台软启动器配1台电机的控制方案，为了节省投资，经过多方论证，并且与上海津信变频器有限公司的技术一起进行了模拟试验，较终决定采用1台软启动器带多台电机的方案。西门子模块代理商|云浮PLC模块代理商其启动控制原理请见图3，启动时为电流闭环控制，等到电机加速至额定转速时，电流也降至额定电流，可控硅开足，较后软启动器发出运行信号。折叠应用领域：软起动器安装调节方便，所有控制连接及参数调节均在正面上完成。
该软启动器可不带旁路持续在线运行。软启动器为旁路和故障单独设置了控制继电器。该软启动器所有参数均通过前面板上的三只旋钮电位计和一只拔码开关设定,直观准确。它甚至可以工作在有振动和环境温度较高的应用场合。
