| 摘 要： | 针对开关柜局部放电检测环境复杂,故障信号定位时间长,准确性差的问题,结合现场实际进行分析研究,提出了基于特高频(Ultra High Frequency,UHF)、暂态地电压(TransientEarth Voltages,TEV)和超声波等检测技术的开关柜局部放电综合检测方法。应用结果表明:综合检测方法能避免干扰信号对检测结果分析判断的影响,快速、有效地检测出开关柜局部放电缺陷。

| Abstract: | Aiming at the problems such as complicated environment,long positioning time and lowlocalization accuracy of fault signal in switch cabinet partial discharge detection,by analyzing andresearching for site actual conditions,puts forward the switch cabinet partial discharge integrateddetection method based on the detection technology of ultra high frequency,transient earth voltageand ultrasonic wave etc.. The application result shows that the integrated detection method can avoidthe influence of interference signal on analyse detection result,and detect quickly and effectivelythe partial discharge fault in switch cabinet. |
