局部放电缺陷在运行过程中会逐渐劣化甚至引发高能放电故障,严重威胁变压器的安全运行。文中基于一台110 kV真型变压器搭建局部放电试验平台,设计了高压引线悬浮金属颗粒、高压引线附近金属尖刺悬浮、静电环悬浮3种悬浮放电缺陷,采用阶梯升压法进行试验,记录局部放电发展过程中脉冲电流、特高频和声信号的变化规律并进行对比分析。发现3种悬浮放电缺陷的“剧烈”放电阶段均不明显,击穿前的放电能量均比较低,声信号频谱没有出现“主频左移”的现象。3种缺陷虽然都是悬浮电位放电,但是其局部放电特征明显不同 ...

气体绝缘金属封闭设备(GIS设备)内部绝缘缺陷导致的局部放电会影响设备的绝缘性能,其中沿面放电是引发GIS设备闪络故障的主要原因。为有效实现局放异常严重程度判定,指导现场GIS局放异常处置,本文提出了基于多物理量的GIS绝缘件沿面放电精细化放电阶段划分策略。首先建立了气体绝缘多物理信号检测试验平台,应用光学传感器、特高频(UHF)传感器和超声波(AE)传感器测量绝缘件不同阶段沿面放电电气量,并与脉冲电流法局放进行数据对照,依照GIS设备绝缘件实际沿面放电可能因素设计沿面放电缺陷模型 ...
