摘 要：励磁涌流是变压器空载合闸时不可避免的现象。从实验角度对励磁涌流的表现加以分析，并以晶闸管配合交流接触器作为核心器件，制造了合闸相位角可控的励磁涌流发生控制装置，模拟实际中可能出现的各种励磁涌流现象，进行相关励磁涌流峰值、衰减特性等的分析。试验结果表明该装置可作为励磁涌流计算的有效验证手段。

Abstract: The excitation inrush current is the inevitable phenomenon in transformer no-load closing. This paper analyzed the phenomenon of excitation inrush current from the corner of experiments. An excitation inrush current generation control device, controlled by the closing phase angle, with thyristors and AC contactor as the core components, was manufactured. This paper simulated various possible arisen phenomena of excitation inrush current in practice and analyzed the related peak value of excitation inrush current, the attenuation characteristics and so on. Experimental results show that the device could be the effective verification way to calculate excitation inrush current.
           Key words: excitation inrush current; thyristor; closing phase angle
