SPWM滤波器手册
一.由于变频器的输出含有高次谐波,增加了动力电缆及电机的损耗。
如果电机需要长线传输时(电机线缆超过50米),由于行波反射引起电机端电压叠加,使电机绝缘破坏,甚至使电缆爆裂。
能同时解决以上问题的有效方法使在变频器输出侧加装滤波器,将PWM调制波形成近似正弦的电压波形,并使电机和变频器的线缆延长
二. 技术规格
1.工作电压:AC660/690V 可选择
2.额定电流:5到2000A
3.基波频率:50/60Hz
4.载波频率:2KHz到20KHz
5.耐压测试:3000V AC 3秒
6.防护等级:IP00
7.绝缘等级:/F (155℃)
8.温度范围:-25℃ to +85℃(风机)
9.过载:1.35倍电流60s(基波电流)
10.周围无有害气体,无易燃易爆物品 周围环境应有良好的通风条件,如装在柜内应加装通风设备。
订货须知.电压.电流.载波频率.变频器是重载或轻载。
