摘　　要：阐明了在一般情况下,电流互感器的变比是一定的。从建立电流互感器的电路和磁路方程出发,通过对比普通电流互感器和有气隙存在的特殊的电流互感器的电路和磁路,从原理上研究当电流互感器内部存在气隙时,二次负载对电流互感器变比的影响。Usually, the TA＇ s ratio of its current in the first side and the second side is certain. Based on the establishment of electric circuit and magnetic circuit, and the comparison between the common current transformer and air gap current transformer, the influence of current transformer to the secondary load when the current transformer are filled with the air gap is analyzed theoretically.
