2-25AMP,AC240V,PDA1系列PCB固态继电器unionelecom,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)。
