摘要

摘要: 在常规大气环境条件下，基于单极性纳秒脉冲电源对表面介质阻挡放电特性进行了实验研究。结果表明:纳秒脉冲表面介质阻挡放电的本质是丝状放电，放电集中在电压脉冲的上升沿；激励电压和脉冲重复频率越大，放电越强烈，越接近均匀放电，但电压的作用更侧重于均匀性，而频率的作用则侧重于放电的强度；电极间隙的优化可以使表面介质阻挡放电特性最好；玻璃作为阻挡介质时容易发生沿面闪络。

Abstract: The characteristics of nanosecond-pulse surface dielectric barrier discharge (DBD)are investigated in air at atmospheric pressure with the domestic repetitive unipolar nanosecond-pulse generator， the characteristic of surface DBD is investigated in this paper. It is found that nanosecond-pulse surface DBD is a filamentary discharge in essence. The discharge happens during the rising time of the applied voltage pulse. Higher applied voltage and Higher repetitive frequency lead to intenser and more uniform discharge. Voltage amplitudeaffects the discharge uniformity more， while pulse repetition frequency affects the discharge intensity more. There is an optimum electrode gap width to get the best electrical characteristics of surface DBD. Moreover， surface flashover is prone to happen when glass is chosen as dielectric barrier.
