摘要
对某变电站不接地系统中的一条由馈出线的断线故障引起的铁磁谐振进行了分析,并对各种可能的断线故障所引起的分频、基频、高频谐振进行了验算,总结了不接地系统的断线谐振的规律,并提出有关预防措施和对策。
Through analyzing the resonant overvoltage due to line-broken fault in the ungrounded system,this paper discusses the regularity of this type ferromagnetic resonance,which is important and significant to study other cases.In the end,some protective measures and the way to prevent the occurrence of resonance are suggested.
