| 摘 要： | 针对常规电流互感器呈现的不足，提出了用Rogowski线圈作为混合式光电电流互感器(HOCT)的传感头器件。根据Rogowski线圈测量原理，分析了Rogowski线圈的等效电路，对两种类型(外积分型和自积分型)Rogowski线圈测量系统的频率特性进行了分析，并就如何拓宽Rogowski线圈频带、提高线圈暂态性能进行了研究，提出了相应的改善方法。

| Abstract: | According to the model of Rogowski coil,tow types of Rogowski coil used to measure different duration of pulsed current with large amplitude are introduced, and their fre-quency characteristics are analyzed.At the same time,how to improve the frequency characteristics of Rogowski coil are discussed, and also means to broaden the bandwidth of frequency response.In addition, some optimal methods are simulated by means of advanced simulation tools based on MATLAB environment. |
