新型磁控式可控电抗器在电网电容电流自动补偿中的应用

Application of Magnetism-controlled Reactors to Capacitive Current Automatic Compensation in Networks

提出将磁控式可控电抗器用作消弧线圈,叙述了单相接地电容电流实时检测方法。由于电抗器本身的优良特性,该补偿方法较好地解决了补偿电网运行时谐振过电压与单相接地后最佳补偿之间的矛盾。制作了低压模型装置,试验结果良好。

The method of using magnetismcontrolled reactors as arcextinguishing coil is put forward. A realtime measuring method for capacitive current in singlephase earth faults is described. Because of the excellent characteristics of magnetismcontrolled reactors, the contradictory between the resonance overvoltage in normal operating networks and optimal compensation in singlephase earth fault can be solved. A low voltage simulation device was built and the satisfactory simulation test results are obtained.
