摘要
本文中作者分析了现有消除或抑制变压器直流偏磁电流主要措施的运用效果,评估了大型变压器耐受直流偏磁电流的能力,从维护电力系统整体可靠性的角度对变压器耐受直流电流数值提出了一些建议。
The application effect of measures to restrain or eliminate DC bias current is analyzed by the authors in this paper. The ability of larger transformer to withstand DC bias current is evaluated based on experiments and Simulation calculation. Some suggestions on the value of DC bias current in large power transformer based on the reliability of power grid system are presented.
