【正文】 Overvoltage research status Mechanism of ferromagic resonance at home and abroad has been exhaustive research, the main reason is when the voltage increases, (then , Of closing the persistent failure resection can cause), PT39。s core saturation, the inductive reactance Xm Linetoground capacitance or circuit breaker equalizing the capacitance of the capacitor and capacitor equipment close to inspire Since a resonant frequency. In the power system to determine Ferromagic resonance occurs in any case will prevent And analysis play a very important role. Opinion at home and abroad in accordance with the above results of ferromagic resonance overvoltage are generally taken to prevent and eliminate Methods, prevention and to eliminate ferroresonance overvoltage is generally considered from two aspects of the running operation, equipment. From running operation Considerations during operation ferroresonance overvoltage, the operation of the equipment or line Road re ored to the state before the operation, and then reoperate. The bus charging power Shi
