摘要

本文讨论了单相常规变压器和超导变压器的数值模型。数学关系的添加使得确定后续阶段的平均和有效电流成为可能，并计算当将无负载的变压器切换到供电网络的全电压时，在绕组中释放的热量。对铜绕组和超导绕组的21 MVA变压器的涌流波形和脉冲进行了计算和比较。

Modeling of the Inrush Current in Superconducting Transformers Using PSpice

The paper discusses numerical models of single-phase conventional and superconducting transformers. The addition of mathematical relationships made it possible to determine the average and effective current in subsequent periods, and to calculate the amount of heat that is released in the windings when switching the unloaded transformer to the full voltage of the supply network. The waveforms and pulses of the inrush current of 21 MVA transformers with copper and superconducting windings were calculated and compared.
