摘要
详细分析了电流互感器(CT)的工作原理和对继电保护影响。建立了CT的电路模型,根据理论分析和仿真结果比较了不同条件下电流互感器的特性,分析了一次幅值大小、非周期分量大小、一次侧时间常数和二次侧负载的大小等因素对电流互感器饱和造成的影响,从而有针对性地提出了防止CT饱和的方法。
The paper analyzes the working principle of a current transformer and the effect on relay protection and a current transformer model has been set up. According to the theoretical analysis and simulation results, compare the cur- rent transformer characteristics under different conditions. Analyze primary amplitude size, aperiodic component size, pri- mary side time constand and secondary side load to the effect on current transformer saturation, thus putting forward stop- ping a method from current transformer saturation.
