1台变频器并联驱动多台电机,请使电机额定容量的总和在变频器的额定输出电流以下,并保留10%余量.
2:怎么解决高次谐波问题?
二极管整流电路会产生……5、7、11、13次……的高次谐波.
影响:电流增大、功率因数下降
对策:请装上AC或DC电抗器(3%压降左右)
3:对于变频器输入侧变压器有什么要求?
当安装大容量机器时,请事先确认变压器阻抗值,变压器容量是否合适.
另外,在下面3个情况下,请在变频器输入侧装上AC电抗器.
特别在小容量变频器和大容量变频器安装在同一地方时要注意以下三点:
①变压器容量超过500KVA时
②变压器与变频器之间的距离小于10M时
③输入电流值大于变频器额定输出电流值时
由于电网电感越小高次谐波电流就会越大,故甚至可能会引起变频器整流桥损坏
