摘　　要：本文在分析CT的暂态特性及其动态磁化过程的基础上,建立了计及铁芯饱和、局部磁滞回环、动态剩磁影响的CT单、复励磁暂态过程数字仿真模型,提出了继电保护用P、TPX、TPY、TPz级CT的电磁优化设计方法,编制了计算机程序,用于CT的电磁优化设计及数字仿真分析.Based on the analysis of the transient characteristics and the dynamic magnetization process of the current transformer, this paper proposes a numerical simulation model for the single and double magnetization transient process of the current transformer, in which the core saturation, partial magnetic domain loop and dynamic remanence are considered. We also present an electromagnetic optimum design method of the P, TPX,TPY and TPZ class for the current transformer in protective relays, and give the calculation program for the electromagnetic optimum design and numerical simulation analysis of the current transformer.
