摘要
针对于变压器空载合闸时励磁涌流的危害性,建立了变压器励磁涌流的数学模型,分析了励磁涌流与变压器剩磁、空载合闸角、励磁阻抗及其幅值之间的关系,在此基础上提出抑制励磁涌流的具体实现方法。
According to the harmful problem of magnetizing inrush current of transformer during no-load closing, the mathematical model of magnetizing inrush current in transformer is established. Based on the analysis of relation among magnetizing inrush current, residual magnetism, switch angle, magnetizing impedance and its magnitude, the approach to suppress the magnetizing inrush current is presented.
