Description

Technical Field

[0001] The present invention relates to the technical field of high-frequency power supply, and in particular to a high-frequency power supply with an intermittent power supply mode. Background Art

[0002] During the use of high-frequency power supply, due to the different characteristics of high-resistance dust inside the electric field, the charge carried by these dusts is not easy to release, and they are adsorbed on the anode plate, forming a residual negative ion layer on the ash layer of the anode plate. From the influence of space charge on the electric field, it can be seen that it will shield part of the electric lines leading to the corona electrode, thereby weakening the field strength near the corona electrode and increasing the field strength near the anode plate, causing the ionization of the corona zone to weaken and the corona current to decrease; as the ash layer on the anode plate area increases, a thin electric field is formed on the surface of the ash layer and the surface of the plate pole line, causing the high-frequency power supply to appear in this electric field. The voltage decreases as the power output current increases, affecting the dust collection effect of the electrostatic precipitator.

[0003] At present, the long-term vibration cleaning method is mostly used, but it is difficult to destroy the ash layer. Changing the output mode of the high voltage of the power supply, intermittent power supply, and instantaneous power supply pulse can destroy the ash layer on the anode plate, but the current high-frequency power supply does not have this function, so our company has developed this high-frequency power supply with intermittent pulse power supply control mode.
