DEVICE FOR SUPPLY OF ELECTRIC APPARATUSES WITH DISCHARGE CORONA-FORMING ELECTRODES Russian patent published in 1998 - IPC

FIELD: pulse supply of electric apparatuses with corona-forming discharge electrodes, for instance, electrostatic precipitators, ozone generators and other apparatuses. SUBSTANCE: supply unit at least of two electric apparatuses with discharge corona-forming electrodes has DC voltage sources according to the number of electric apparatuses, whose one of the poles is connected to the common bus, and the other - to the corona-forming electrodes of one of the apparatuses via current-limiting elements, and a pulse voltage generator with one DC voltage source connected to the common bus through one of its poles opposite with respect to the common bus of the other specified DC voltage sources, and a key system of pulse switching connected to the generator DC voltage source via current-limiting element, and to the corona - forming electrodes-via blocking capacitors according to the number of electric apparatuses, and the voltage generator is connected to a reservoir capacitor. EFFECT: simplified circuitry and improved economic and reliability characteristics. 2 cl, 1 dwg
