【正文】 on 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 ShiningHub circuit breaker, and then close then Transformer or voltage transformer and inductor device on the bus. Ferromagic resonance occurs in the operation, the temporary investment of Into the arc suppression coil or specified in advance some of the lines or equipment, such as shunt capacitor banks or standby line. From the device Considerations, (1) in the star connection voltage transformer primary winding neutral point and ground installation of harmonic elimination, such as: 635 type LXQ (Resistor R), R in series by a SiC nonlinear resistor and a linear resistor (6 7kΩ ), this Sample can directly absorb vibration energy, to prevent resonance occurs, this damping method is particularly suitable for large capacitance on Grid。 (4) 10 to 35 kV power The pressure transformer used in all the harmonic elimination voltage transformer. More than the prevention and elimination of ferroresonance overvo
