摘要
研究了用铁氧体磁环抑制全封闭组合电器 (GIS)的特快速暂态过电压 (VFTO)的可能性。低电压模拟试验表明 ,在导体上放置铁氧体磁环等效于在导体中接入一个并联的电感和电阻 ,能够阻尼行波的传播 ,抑制快速暂态过程。
Investigation was performed on the possibility of suppressing Very Fast Transient Overvoltage(VFTO)in Gas Insulated Substations(GIS)by ferrite rings.A low voltage simulation test showed that putting ferrite rings around a conductor is equivalent to placing into the circuit an inductance and a resistance in parallel which can damp the travelling waves propagating through and suppress the fast transients.
