摘要
介绍了局部放电检测技术的原理和应用,并结合某供电公司现场检测案例对3种检测方法进行分析和比较,结果表明特高频法具有较高的灵敏度,尤其适用于开关柜绝缘类缺陷的现场检测。当对开关柜进行局部放电检测时,建议侧重特高频检测。
The principle and application of partial discharge detection technology are introduced and three kinds of detection methods are analyzed and compared combining with the on-site detection cases in an electric power supply company.It is found out that UHF method has relatively higher sensitivity and is especially suitable for the on-site detection of switchgear insulation defects.The UHF detection method is more recommended when carrying out partial discharge detection on switchgears.
