ABSTRACT:
The method of supplying voltage to an electrostatic precipitator, includes periodically reversing the polarity of a supply voltage; intermittently supplying voltage to the precipitator; and the supply voltage polarity being reversed during no-voltage intervals, with the reversing of polarity being delayed with respect to the beginning of the no-voltage interval. An apparatus, for supplying voltage to a high-ohmic dust electrostatic precipitator, includes a step-up transformer including a thyristor controller placed in a primary winding circuit of the step-up transformer; a switching device connected to a secondary winding circuit of the transformer and to the precipitator, the switching device being made in the form of two transit pentodes having control solenoids whose axes are perpendicular to the axis of the corresponding pentode, the pentodes being in an inverse-parallel relationship; a regulating unit including a protection unit and being connected to the input of a thyristor controller, the protection unit having a thyristor key; and a control unit including a master oscillator having one output connected to a control electrode of the thyristor key in the protection unit and its other output connected through a flip-flop and power amplifiers to control solenoids of the transit pentodes.
