摘要
阐述了保护用电流互感器的非线性和剩磁部题，对暂态保护用电流互感器的工作状态进行了理论分析，建立了相应的数学模型，并进行了计算机仿真，经仿真计算后，可方便地得到当电流互感器一次侧流过短路电流时的最大瞬时峰值误差。仿真计算实例得到的最大峰值误差为８．１％
The nonlinearity and remanene of the current transformer for transient protection are discnssed.Tneoretical analysis is made of the operational condition of the current transformer for transient protection,which matnematical model is set,and is taken to computer simulation.Based on the simulation,the error value of the transient maximal peak value is obtained conveniently.The error of transient maximal,from practical simulation,is 8.1%.
