摘要
为了研究电压形式对SF_6气体放电分解特性的影响,搭建了SF_6气体分解实验平台,对比研究了SOF_2、SO_2F_2、SO_2等3种含氟含硫气体在正负极性直流及交流电压下的生成情况。结果表明:正极性电压下的平均局部放电量和最大放电量明显大于负极性电压;电荷分布随电压极性变化,正极性电压下的SF_6分解率高于负极性电压;受到峰值电压、极性反转、电荷分布等的影响,交流电压下的SF_6分解率高于正极性直流电压。
In order to study the influence of discharge form on decomposition characteristics of SF6, an experimental and testing platform for SF6 was designed. The content variation of SOF2, SO2F2, and SO2 were comparative studied under AC voltage and positive and negative DC voltage. The results indicate that the mean discharge magnitude and maximum discharge quantity under positive DC voltage are obvi- ously higher than those under negative DC voltage. Because the charge distribution would change with voltage polarity, the decomposition rate of SF6 is higher under positive DC voltage than that under nega- tive DC voltage. Because of the effect of peak voltage, polarity reversal, and charge distribution, the decomposition rate of SF6 under AC voltage is higher than that under positive DC voltage.
