摘  要:
介绍盖州农电局66kV变电所内10kV电压互感器的运行情况和铁磁谐振过电压产生的机理,对当地运用的3种防铁磁谐振方法进行比对,结果表明:采用抗谐振型PT或在中性点串单相PT这两种装置,能有效抑制铁磁谐振。

摘  要:
The operation conditions of 10kV voltage transformer in the 66kv substation in Gaizhou Agriculture Bureau and the generation mechanism of ferromagnetic-resonance overvoltage were introduced in the paper, and the three kinds of anti ferromagnetic-resonance methods were compared here as well. The results showed that: the two devices such as anti-resonance PT or neutral point connecting single-phase PT could control ferromagnetic-resonance effectively.
