The electric field intensity carried by the pulse power supply is low, so that the dust removal efficiency is lower, but the electric field operates well. Under the condition that the spark rate of an electric field carried by a high-frequency power supply is suddenly increased, the spark rate is out of standard when the secondary current is low, and effective dust removal cannot be achieved, and the failure causes mainly include 1 power failure and 2 internal failure of the electric field for electric dust removal. But the two causes of the fault cannot be accurately judged. When judging that the fault exists in the electric field carried by the high-frequency power supply, the fault needs to be treated after the machine set is stopped, and the high-frequency power supply has high dust removal ratio, so that once the electric field is stopped, the load of the machine set is influenced due to long treatment time of complex structure in the electric field.
