摘要
本文对电流互感器的工作原理、线路进行了理论分析与介绍。并且根据换算到副边的等值电路图进行特性参数计算。最后举例说明其在电动机控制与保护装置中作为电流检测元件是不可缺少的。
The operating principle and the circuit of the current transformer are thcoretically analyzed and presented in the article.The characteristic parameters of the equivalent circuit diagram are calculated according to the reduction to the secordary.At last the article illustrates with examples that it is indispensable to them as current detecting elements in the motor control and protective device.
