Cause and Precautionary Measures for the Resonance of the Electric Wire Netting Overvoltage

在10kV电力系统中经常发生谐振过电压现象,造成电气设备损坏和大面积的停电事故,严重影响设备的安全运行和供电可靠性,是极大的不安全因素。本文作者对谐振过电压现象不安全产生的原因作了简单分析论述,并提出了相关防范措施。

For a long time, the phenomenon of voltage of resonance often takes place in 10kV power system. Once overvoltage happens, it often causes the accident of electric equipment damage and power cut in a large area, it seriously influences the safe operation of equipment and power supply reliability. So it is the greatest unsafe factor. This paper introduces the unsafe reasons for the phenomenon of resonance overvoltage, and puts forward the relevant precautionary measures.
