摘要
针对非有效接地系统易发生谐振的问题,分析了系统产生谐振电压的机理,并着重阐述了电压互感器铁磁谐振及系统断相接地引起谐振的产生及消除措施,提出了防止非有效接地系统发生谐振的方法。
Analyses the mechanism of resonant voltage generated in the non-effective earthing system,which is susceptible to resonance,discusses the ferromagnetic resonance of voltage transformer and the resonance resulting from phase-broken earthing of the system and the measures to eliminate them in particular,and suggests the way to prevent the occurrence of resonance in the non -effective earthing system.
