摘要
在线-板电晕放电反应器模型上,分别采用电阻率较高的镍铬不锈钢线和电阻率较低的青铜线作为电晕线进行了脉冲电晕放电试验研究。结果表明,在其它条件相同的情况下,镍铬不锈钢线比青铜线上的纳秒脉冲衰减要大,两者的差别达15％。这表明,在纳秒脉冲电晕放电的实际应用中,电晕线的电阻率对纳秒脉冲电晕放电的衰减影响不容忽视。
A line-plate corona discharge model is setup. Two corona wires with different resistivity are used in the model respectively. The pulse amplitudes are measured along the wire and the corona discharge images are taken with a high sensitive image record system. The nanosecond pulse corona discharge attenuation data from these corona wires are compared and discussed. The results show that the nanosecond pulse and the corona image along the wire with high resistivity are attenuated more sharply than that with lower resistivity. The attenuation difference is up to 15%. Therefore, the attenuation shouldn't be ignored in the pulse corona discharge application.
