摘要
电力电缆局放测试中,传感器的灵敏度、带宽、信号品质等特性决定了局放测试的成败,利用电磁耦合技术(ECT)对电缆进行宽频带局放检测,结果表明,ECT技术可对超低电压下的XLPE电缆绝缘缺陷进行有效检测。文章简单讨论用于XLPE电力电缆局放检测的宽频带电磁耦合法,深入探讨和研究应用要点。
In partial discharge testing of power cables,the sensitivity,bandwidth,signal quality,and other characteristics of sensors determine the success or failure of partial discharge testing.Electromagnetic coupling technology(ECT)is used for broadband partial discharge detection of cables.Research has shown that ECT technology can effectively detect insulation defects in XLPE cables under ultra-low voltage.Based on this,this article briefly discusses the overview of broadband live magnetic coupling method for partial discharge detection of XLPE power cables,and deeply explores the research and application points for reference.
