摘　　要：随着电网发展系统容量增大,具有成本低、额外占地面积小、限制系统短路电流能力强等特点的高阻抗变压器应用率不断提高。目前国外对于高阻抗变压器的研究较少,而国内对于高阻抗变压器未形成系统性研究。首先介绍高阻抗变压器的定义和设计原理,对不同高阻抗变压器的实现方式进行总结。其次,针对高阻抗变压器应用过程中凸显的励磁涌流问题开展理论分析。最后,对高阻抗变压器励磁涌流抑制措施进行总结和对比,并对高阻抗变压器的研究和应用前景进行展望。With the increase of system capacity in the development of power grid,the application rate of high impedance transformer with low cost,small extra floor area and strong ability to limit system short-circuit current is increasing.At present,there are few studies on high impedance transformers abroad,and there is no systematic study on high impedance transformers in China.Firstly,the definition and design principle of high impedance transformer are introduced,and the realization methods of different high impedance transformers are summarized.Secondly,the excitation inrush current of high impedance transformer is analyzed theoretically.Finally,the excitation inrush current suppression measures of high impedance transformer are summarized and compared,and the prospects of research and application of high impedance transformer are prospected.
