IONIC PURIFICATION DEVICE, AND FREQUENCY MODULATION METHOD AND SYSTEM OF TRANSFORMER

摘要

The present invention provides a high-pressure ionic purification device, comprising: a generation electrode, a collector, and a support body. The generation electrode is used for imposing high pressure. The collector is disposed opposite to the generation electrode, and is used for imposing high pressure and forming a high-pressure electric field with the generation electrode, and the generation electrode and the collector have a gas channel. The support body supports edges of the generation electrode and the collector, and is used for performing electrical isolation on the generation electrode and the collector, and fixing the generation electrode and the collector mechanically, and a surface of the support body between the generation electrode and the collector comprises a surface covering layer with characteristics of ion bombardment resistance and accidental arc discharge resistance. Because the surface of the support body comprises the surface covering layer with characteristics of ion bombardment resistance and accidental arc discharge resistance, in high-humidity environment, a discharge channel along the surface of the support body is not formed between the generation electrode and the collector, which can effectively lengthen a life span of the purification device. The present invention also provides a method and a system for modulating an operation frequency of a transformer. The method comprises: selecting, in a preset range, at least three frequencies comprising an initial frequency, a frequency smaller than the initial frequency, and a frequency greater than the initial frequency; respectively inputting driving voltage of the selected frequencies to the transformer and operating for a same preset time, and respectively recording output voltage of the transformer corresponding to the driving voltage of the selected frequencies; determining a frequency corresponding to the minimum output voltage as a modulated frequency of the driving voltage of the transformer; and inputting the driving voltage of the modulated frequency to the transformer. By means of the method in the present invention, an operation frequency of the transformer is close to an optimal operation frequency as far as possible, and if a preset range is selected appropriately, an optimal operation frequency of the transformer can be determined, thereby ensuring maximum development of performance of the transformer, and eliminating influences caused by a frequency offset.
