Abstract:

笔者对GIS断路器与隔离开关动作时所产生的VFTO辐射场进行了测量与分析。首先研制了一套基于光纤传输的VFTO辐射电场测量系统,并对该测量系统进行了标定实验,结果显示该测量系统具有响应频带宽、抗干扰能力强和传输距离远的特点。然后选取了典型的330kV超高压GIS变电站,应用光纤测量系统对其开关正常动作时所引发的VFTO辐射场信号进行了测量。比较了断路器与隔离开关动作所产生的VFTO辐射场之间的差异,分析了差异产生的机理。同时也比较分析了相同开关的不同操作所产生VFTO辐射场之间的差异和机理。结论显示开关电弧放电位置与其引起的辐射场信号的频谱幅值分布具有紧密的联系。文中的研究成果对GIS变电站的在线监测提供了测量手段与依据。
