摘要
对电网运行经常出现铁磁谐振过电压的现象进行了分析和研究 ,提出了一种新的检测和控制技术。应用该技术研制的监测装置适用于一般电网情况下的运行监测 ,有利于电网避免 PT因谐振过电压而烧毁、爆炸 。
The ferromagnetic resonance over-voltage usually occurs in network is analyzed in this paper. and put forward a new inspecting and controlling technology. Based on the technology, an inspecting device is developed, which is suitable for common working network, and beneficial to avoiding burn, explosion and severe accident happening.
