摘要
通过特高频检测诊断技术,成功定位了一起开关柜绝缘放电缺陷,结合停电耐压试验进行验证,证明了特高频检测技术在开关柜局部放电诊断中的有效性,且通过特高频及高速示波器可准确定位,并准确评估缺陷严重程度,实现精准检修。
In this paper,an insulation discharge defect of switchgears is successfully located through UHF detection and diagnosis technology.Combined with withstand voltage test,it is proved that UHF detection technology is effective in partial discharge diagnosis of switchgears.The wave detector can accurately locate and accurately evaluate the severity of defects,so as to realize precise maintenance.
