污秽绝缘子可听噪声和电晕关系试验研究

Dianci bileiqi
污秽绝缘子在不同的污秽等级、湿度环境下发生电晕现象的同时会产生可听噪声。本研究试验测试了绝缘子可听噪声和污秽等级以及电晕电流之间的关系，获得了不同污秽等级、湿度条件下绝缘子电晕放电产生可听噪声和脉冲电流的时域波形，从可听噪声频谱产生角度，分析了电晕电流和可听噪声的关联规律，利用统计方法分析了电晕电流1/3倍频谱不同频点处幅值与可听噪声A声级的关联关系，分析测量并获取可听噪声频谱特征与电晕电流的关系趋势。结果发现了随着污秽等级和湿度的增加，污秽绝缘子可听噪声和电晕电流成增大趋势，并且二者之间存在线性关系 ...

盘形悬式绝缘子电晕的研究

Dianci bileiqi, 1994
盘形悬式绝缘子电晕的研究绝缘子元件电晕放电会产生噪音。为了提高决定噪音水平的绝缘子容许电压，开展了悬式绝缘子电晕的研究。连续地升高工频电压，就可求出发生可见流光电晕的电压与其结构的关系。还求出了与水泥胶合剂端场强最大部位的圆断面的半径的关系。［摘译自...
