GIS一体化局部放电缺陷模拟装置研制与应用

摘要

Real GIS device has poor repeatability,stability and controllability when used in field testing.Four typical insulation defects are studied and an integrated GIS simulation device is designed.The device has ability to simulate different kinds of partial discharge defects during online and offline operation and detection.Then a simulation test platform is set up to study four typical insulation defects.Testing data and graphs are studied to reflect GIS operation status.The proposed device provides important basis for GIS equipment maintenance,overcomes field environment constraints,improves efficiency and saves maintenance costs.%针对真实GIS设备内部绝缘缺陷稳定性不好、重复性差、无法在设备体外控制放电等缺陷,研究了4种典型绝缘缺陷对GIS局部放电的影响,并设计了一体化的GIS局部放电缺陷模拟装置.该装置能够模拟4种绝缘缺陷,实现了停电与带电的同步检测.通过搭建模拟实验平台,研究了4种典型绝缘缺陷的放电特征,并进行了数据、图谱对比,确切地反映了GIS运行状况,克服现场环境的约束,提高检修效率,节省检修费用,可以为电网GIS设备检修提供重要依据.
