摘要
对几种典型的现代电器设备进行了谐波电流实测,发现大多数现代办公室和家用电器的谐波电流超标严重,分析了波形畸变的原因;设计出了适合现代电器设备的滤波电路,并通过实验验证了此种滤波方法效果较好,可以在电器设备中推广。
Harmonic currents of several topical modern electrical facilities have been measured.It is found that most present modern offices and household electric appliances harmonic current are badly exceed,analyze the reason of waveform abnormalities,and designe a filtering circuit suit for electrical facilities.This filtering method is verified better by the experiment.It can be promoted on electrical facilities.
