| Abstract: | After the reform of the gantry crane by electricity instead of oil,the harmonic wave of the power supply circuit has been produced.Restraining the harmonic wave is an important method to improve the quality of the power supplied.This paper analyses the causes of the harmonic wave in the current and voltage of power supply circuit after electricity instead of oil,states the damage of the harmonic wave.Then it introduces 3 methods for restraining the harmonic wave of current and voltage in the power supply ci... |
