Abstract (en)

[origin: WO8809214A1] A device for power supply to gas-cleaning electrofilters comprises two direct-voltage sources (1, 2) the opposite poles (5, 6) of each of them being earthed. Between the other opposite poles of each of the direct-voltage sources (1, 2) and a corona electrode (16) of an electrofilter (17) two high-voltage commutators are connected consisting of triode-type electron-ray rectifiers (7, 8) with a hollow anode (11). To the cathode (9) and to the control electrode (10) of each electron-ray rectifier (7, 8) are connected alternating voltage modulators (18, 19) connected, through dividing transformers (38, 39), to a control unit (40) connected in turn to sensors (49, 50, 51, 52) of electrical and physical parameters. Each electrical circuit contains, connected in series, the direct-voltage source (1, 2), the electron-ray rectifier (7, 8) and the corona electrode (16) of the electrofilter (17) and comprises inductive accumulating elements (13, 15) connected in series.
