微缩GIS中VFTO的传播特性研究

Gaoya dianqi
气体绝缘金属封闭开关设备（gas-insulated metal-enclosed switchgear, GIS）在进行开关操作时会产生严重电磁干扰，为了减小特快速暂态过电压（very fast transient overvoltage, VFTO）等电磁暂态过程对二次设备的影响，文中搭建微缩GIS模拟实验平台，对VFTO在GIS中的传播特性进行研究。结果表明，线路末端VFTO的波形在空载情况下剧烈振荡，阻性负载下单调衰减，容性负载下阻尼性波动衰减。VFTO最大幅值与传输距离和负载性质有关 ...

特高压GIS用磁环型阻尼母线VFTO抑制性能试验研究

Gaoya dianqi
GIS中的隔离开关在操作过程中由于断口重复击穿会产生特快速瞬态过电压（very fast transient overvoltage，VFTO）。VFTO幅值高、波前陡，严重威胁电气一次绝缘，并会产生电磁干扰问题。目前，实际工程中除采用带投切电阻的隔离开关抑制VFTO外，还可以采用磁环型阻尼母线对VFTO进行抑制。为了保证GIS的可靠性，磁环型阻尼母线抑制性能的优劣至关重要。为此，亟需研究提出一种在试验室进行磁环抑制效果的评定方法。文中针对磁环型阻尼母线的抑制性能，设计了专门的抑制性能试验回路 ...
