【摘要】 为了解决介质阻挡放电 (DBD)反应器放电性能随激励频率提高反而下降的问题 ,采用电荷电压测量等方法对DBD系统主要放电参量的变化规律进行了实验研究。结果表明 :由激励变压器漏感与电介质层等效电容引起的系统谐振是造成这一问题的主要原因。DBD系统谐振不但能引起放电间隙等效电压、电介质层等效电压、放电间隙等效电阻等放电参量的异常变化 ,降低DBD反应器放电性能 ,而且会对激励变压器与DBD反应器中电介质层的绝缘产生危害 ,影响DBD系统工作稳定性。减小激励电源漏感与合理分布DBD电介质层等效电容是解决DBD谐振问题的有效措施。更多还原

【Abstract】 Abnormal phenomena that discharge performance declines when the frequency of power supply increase have been observed in many DBD device. In this paper, some discharge parameters of DBD device are studied. As a result, the resonance formed by the transformer leak inductance of power supply and the equivalent capacitance of dielectric layer is a key reason resulting in the abnormal phenomena. Therefore the discharge parameters of DBD device should be optimized for avoiding resonance damages and improving DBD discharge characteristics.更多还原
