Abstract:
An electrostatic painting device comprising:a painting device body; a high-voltage booster circuit in said painting device body, said high-voltage booster circuit being operable to receive a high-frequency low voltage and to rectify the high-frequency low voltage and generate a DC high voltage for electrostatic painting; a high-frequency low-voltage generator independent of said painting device body, said high-frequency low-voltage generator being operable to generate the high-frequency low voltage; a low-voltage cable connecting said high-frequency low-voltage generator to said high-voltage booster circuit; a current sensor for detecting a current value of an intrinsic consumed current at said high-voltage booster circuit; and a frequency control device for adjusting a frequency of the high-frequency low voltage such that the current value detected by said current sensor does not exceed a prescribed value.
