Abstract

In this work measurements of atmospheric AC electric arc discharge acoustic spectrum have been performed. Electric and acoustic parameters of discharge are recorder simultaneously. Correlation of acoustic spectrum to electric voltage, current and power has been estimated. Analysis of harmonic spectrums of electric and acoustic discharge dynamic parameters has been performed. Overlapping of electric and acoustic results is presented in the frequency domain. There is a good agreement between electric power spectrum and acoustic power spectrum of the AC arc discharge.

交流电弧放电声谱的测量
本文对大气交流电弧放电声谱进行了测量。同时记录放电的电学和声学参数。估计了声谱与电压、电流和功率的相关性。进行了电声放电动态参数的谐波谱分析。电声结果在频域呈现重叠。交流电弧放电的电功率谱与声功率谱具有较好的一致性。
