摘要 为了研究直流电晕放电产生的可听噪声时域特性,基于实验室搭建的电晕放电测试平台,获得了正负极性直流单点电晕放电产生的可听噪声的时域波形,并对放电产生的可听噪声的时域特性进行了分析。同时,基于该实验平台,也获得了可听噪声脉冲与电晕电流脉冲在时间上的关联特性。实验结果表明:直流电晕放电产生的可听噪声时域波形具有双极性脉冲性质,正极性电晕放电产生的噪声脉冲幅值和脉冲上升时间比负极性电晕放电产生的噪声的相应值大;在时域上可听噪声脉冲与电晕电流脉冲具有一一对应关系。结合实验结果与正负极性电晕放电通道的发展过程,定性地解释了正负极性电晕放电噪声特性的差异及电晕放电噪声与电晕电流在时间上存在一一对应的原因。 In order to obtain the time-domain characteristics of the audible noise caused by direct current (DC) corona discharge, an experiment platform was built in the indoor laboratory. The time domain characteristics of audible noise generated by single corona source on the conductor DC voltage were obtained and analyzed. Besides, the correlated characteristics between the audible noise and the corona current in time domain were also presented based on the test platform. The results show that the audible noise generated by the DC corona discharge has bipolar pulse property. The maximum pulse amplitude and the rise time of the noise pulse caused by positive discharge are both higher than those from the negative discharge. The audible noise pulses and the corona current pulses have one-to-one relationship in time domain. Based on the development process of the discharge avalanche, some qualitative explanations were given to explain the differences audible noise characteristics between the positive and negative. Furthermore, the correlation characteristics of audible noise and corona current are also explained.
