Abstract:

探究了暂态对地电压(transient earth voltage,TEV)法对于开关柜局部放电现象的检测性能,并与脉冲电流检测的效果进行了对比。研究了二者对于不同类型局部放电的检出能力;分析了2种方法测量下4种局部放电PRPD(phase resolved partial discharge)图谱的相似性与差异;通过统计特征参数计算研究了2种检测方法的测量结果随外施电压变化而变化的趋势。结果表明,与传统的高频脉冲电流检测法(highfrequency current transformer,HFCT)相比,暂态对地电压法对于开关柜局部放电的测量信噪比较低,检测效果稍逊,但更适用于微弱尖端放电...
