电力设备的状态检测技术在电力系统中得到越来越广泛的应用,并取得了显著成效.本文首先对状态检测特别是带电检测技术的研究应用现状及面临的问题进行了总结,结合实际情况提出了输变配电设备状态检测实验平台的设计方案.然后,利用110kV GIS、变压器、电缆及10kV开关柜、箱变等真型设备,在机械结构、绝缘性能、内置传感器优化布局、典型缺陷设置等方面进行了设计改进,研制了变压器、GIS内置特高频局放传感器、高压电缆内置电容型高频局放传感器,并建设完成了包括GIS、变压器、高压电缆、配网设备在内的输变配电设备状态检测实验平台.并在该真型实验平台上对变压器、GIS、高压电缆、配电设备典型局部放缺陷进行了同步模拟与检测实验.结果表明,该平台能够完成输变配电设备状态检测技术的研究开发、技能培训、仪器校验与比对等工作,能够真实模拟变电站运行工况、复杂电磁环境下各种输变配设备典型缺陷,对推动状态检测技术的研究与应用具有重要的实际意义.

众所周知,当电缆在恶劣环境下运行时,容易造成绝缘性能的劣化,而电缆附件(包括中间接头和终端)是电缆线路的薄弱环节,其绝缘屏蔽口处的电应力集中容易发生故障。有研究表明,对于高压电缆线路运行故障,约80%以上都是由电缆附件引起的。因此局部放电试验能够有效检测并定位电缆附件中的潜在绝缘缺陷,是电缆状态评估工作的重要组成部分.本文从电缆附件的制作过程和安装工艺,分析了电缆附件发生局部放电的原因,其次详细介
