摘要
针对配电网架空线和电缆较多、线路比较长、单相接地电容电流较大从而对电网安全运行构成隐患的问题,采用智能消弧线圈成套装置自动检测电网的电容电流并进行实时补偿,实际应用证明该装置安全、可靠,消除了以往各类自动跟踪消弧线圈的缺陷,获得了很好的效果。
Because of the over-head distribution lines,more cables,long lines,and larger single-phase-to-ground capacitance current,there are hidden troubles in the safe operation of power system,so intelligent arcsuppression coil system is adopted to detect the capacitive current of distribution network automatically and take real-time compensate.Practical applications show that the system is safe,reliable,and can overcome the local shortcomings of previous automatic tracking arc-suppression coil to achieve better results.
