当线圈通以交流电流时,在感应元件的电磁铁中,由于短路环的移相作用,产生两个相位不同的磁通,此磁通与其在铝盘中感应的涡流相互作用,产生电磁力知使铝盘旋转,当电流增大到整定电流时,电磁力矩大于弹簧的反作用力矩,铝支架转动,扇齿与蜗杆咬合,并随着蜗杆旋转而上升,其顶杆推动电磁元件的动铁,当动铁与电磁铁之间的气隙减小到一定程度时,动铁被吸合,动铁尾部的顶板推动接点闭合,并推下信号牌,显示继电器过电流状态。设备介绍编辑原理电磁式过流继电器的工作原理是复合式的，由公用一个线圈的感应式和电磁式的两个元件组成。当继电器的线圈通以交流电流时，则在铁芯的遮蔽与未遮蔽部分产生两个具有一定相位差的磁通。此磁通与其在圆盘中感应的涡流相互作用。

本人认为，启动时变频器输出电压和频率是逐渐上升的，电机被水淋湿后，会造成输出电流的变化率很高，从而引起直流回路过压。(2)控制辊道电机的AEGMaxiverter-170/380变频器出现速度反馈值大于速度设定值经观察发现:a)在轧钢过程中不存在这种情况，当钢离开辊道后，才出现这种情况;b)当速度反馈值大于速度设定值时，直流回路电压为额定电压的125%，超过115%的极限设定值;c)变频器的进线电压已超过上限;在轧钢过程中，该变频器控制的辊道电机将升速，当钢离开辊道后辊道电机速度降至原来的速度，因这台变频器未装设制动装置，减速时是通过电压调节器限制制动电流以保持直流回路电压不超过115%的极限设定值(缺省值)。

而负载电机的频率高于变频器的输出频率，负载电机处于发电状态，机械能转化为电能，并被变频器直流侧的平波电容吸收，当这种能量足够大时，就会产生所谓的“泵升现象”，变频器直流侧的电压会超过直流母线的电压而跳闸，对于这种故障，一是将减速时间参数设置长些或增大制动电阻或增加制动单元；二是将变频器的停止方式设置为自由停车。5)电机发热，变频器显示过载对于已经投入运行的变频器如果出现这种故障，就必须检查负载的状况；对于新安装的变频器如果出现这种故障，很可能是V/F曲线设置不当或电机参数设置有问题，如一台新装变频器，其驱动的是一台变频电机，电机额定参数为220V/50Hz，而变频器出厂时设置为380V/50Hz。

还可以延长设备的使用寿命，同时可以节能40%。实现电机软启动电机硬启动不仅会对电网造成严重的冲击，而且会对电网容量要求过高，启动时产生的大电流和震动对挡板和阀门的损害极大，对设备、管路的使用寿命极为不利。而使用变频器后，变频器的软启动功能将使启动电流从零开始变化，值也不超过额定电流，减轻了对电网的冲击和对供电容量的要求，延长了设备和阀门的使用寿命，同时也节省设备的维护费用。分类1．按输入电压等级分类变频器按输入电压等级可分低压变频器和高压变频器，低压变频器国内常见的有单相220V变频器、三相220V变频器、i相380V变频器。高压变频器常见有6kV、10kV变压器，控制方式一般是按高低一高变频器或高一高变频器方式进行变换的。

二次侧额定电流通常为1A或5A。其中2×a/C表示同一台产品有两种电流比，通过改变产品的连接片接线方式实现，当串联时，电流比为a/c，并联时电流比为2×a/C。一般情况下，计量用电流互感器变流比的选择应使其一次额定电流I1n不小于线路中的负荷电流（即计算IC）。如线路中负荷计算电流为350A，则电流互感器的变流比应选择400/5。保护用的电流互感器为保证其准确度要求，可以将变比选得大一些。准确级应根据测量准确度[8]要求选择电流互感器的准确级并进行校验。下表为不同准确级电流互感器的误差限值：电流互感器准确级和误差限值电流互感器准确级和误差限值准确级选择的原则：计费计量用的电流互感器其准确级不低于0．5级；
