摘要
为检测10kV开关柜内部绝缘缺陷或劣化、接触不良等问题,分别介绍了基于暂态对地电压(TEV)、超声波(AE)、超高频(UHF)检测方法,采用3种原理联合测试的方法,能为检修工作提供数据依据,保障10kV开关柜的安全运行。
To detect the insulation defects in 10 kV switchgear such as deterioration and bad contact,a combined partial discharge detection technique based on transient voltage（TEV）,ultrasonic（AE） and ultra-high frequency（UHF） was proposed,which provides a data basis for the repairing of 10 kV switchgear and ensures the safety operation.
