摘要(Abstract):
对某变电站非有效接地系统的一条馈出线的断线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、高频谐振分别进行了验算。总结非有效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 analysing a resonant voltage resulting from phase-broken fault in the non_effective ground 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 ocˉcurrence of resonance are suggested.
