应用 Applications
变频器输出侧一般含较多高次谐波。当电机与变频器距离较远时,因线路中由较大的分布电容。其中某次谐波可能在回路中产生谐振,带来两个方面影响:
1) 破坏电机绝缘性能,长时间会损坏电机;
2) 产生大漏电流,引起变频器频繁保护。
一般变频器和电机超过100m,建议在变频器输出侧和电机之间靠近变频器加装交流输出电抗器。
The inverter output voltage usually has high frequency harmonics. The distributed capacitance will be big if the inverter is far away from the motor, therefore resonance may occur, which may result in:
1) Damaging the motor insulation and damaging motor that has been in this status for a long time;
2) Big leakage current and make the enter into protective status frequently.
If the distance between the inverter and the motor is longer than 100m, it is recommended to install the AC output reactor, which connected between the inverter output and the motor, and the reactor shall be as close to the inverter as possible.
