【摘要】 变频器产生的高次谐波会使供电系统产生附加损耗,导致电机过热,影响系统安全和补偿电容的使用寿命及效果。通过使用有源电力滤波器,降低了平均视在功率和变压器损耗,提高了导线的使用寿命,保证了设备的安全运行。更多还原

【Abstract】 The high order harmonic generated by frequency converter will cause additional loss in the power supply system, resulting in motor overheating, affecting the system safety and the service life and effect of compensation capacitor. By using active power filter, the average apparent power and transformer loss are reduced, the service life of the wire is improved, and the safe operation of the equipment is guaranteed.更多还原
