[technical field]
The utility model relates to a kind of DC power system, particularly a kind of medium-frequency high-voltage dual output DC power system.
[background technology]
The routine intravenous electric precipitation adopts the high direct voltage supply power mode.Under this supply power mode, because dust layer equivalent capacity effect can cause back corona phenomenon, cause dust removal efficiency to descend.When adopting pulse power supply, the equivalent capacity of deduster dust layer is only filled electric charge seldom with during pulse applies, during pulse disappears, the lotus of charging discharges substantially, so can not make dust cause anti-corona because stored charge forms high voltage on the deduster dust layer.Therefore with the deduster of conventional DC power supply, compare, the dust removing effects of pulse power supply power supply deduster is better.Electric cleaner pulse power supply power supply adopts the design of superposition pulse voltage on the direct current basic voltage mostly both at home and abroad at present, therefore, need to form two cover power supplys with two transformers, be respectively used to produce DC base voltage and pulse voltage, this just causes all more complicated of the structure of power supply and control system, expensive.
