为探寻提高臭氧发生器功率因数、降低能量消耗的途径,优化臭氧发生器结构参数及其与高压高频电源的匹配,设计了介质阻挡放电型臭氧发生器试验系统,研究了介质材料、介质厚度以及放电气隙等因素对臭氧发生器功率因数的影响,并进行了理论分析。结果表明:选择相对介电常数较大、较薄的材料作为放电介质更易获得较大的功率因素;较小的放电气隙有利于提高放电的均匀性和功率因素;增大激励电压或频率同样会使功率因素增加。
To explore the way of improving ozone generator's power factor,reducing energy consumption,optimizing its structural parameters and improving its matching with high-voltage andhigh-frequency power supply,an experimental system for dielectric barrier discharge(DBD)-typeozone generator was designed.The impact of dielectric material,dielectric thickness,discharge gap and other parameters on the power factor was researched and theoretically analyzed.The results show that the intensity of discharge and power factor rise with the increase of dielectric constant and drop with the increase of dielectric thickness.Reducing the air gap will promote the steadiness and intensity of the discharge and increase the power factor;and increasing the voltage and frequency of power supply will make the discharge much more intense.
