摘要
基于Rogowski线圈的电流互感器与传统电流互感器相比具有广泛应用前景,备受关注。但Rogowski线圈的自身特性以及后续信号处理电路一直影响着电子电流互感器的测量精度,本文对Rogowski线圈的积分算法进行了研究,分别叙述了模拟和数字两种算法及其实现形式,并对其性能进行了分析。从中得到了一些有益结论,可进一步改善积分环节,提高电子电流互感器的测量精度。
The current transducers based on Rogowski coil will be applied more extensively than traditional current transducers. But the characteristic and the follow-up signal processing electronic circuits of the Rogowski coil have affected the measurement accuracy of the electric current transducers. The integral arithmetic of coil Rogowski is studied in this paper, the arithmetic of analog and digital, the format of implement are described, whose performances are analyzed respectively. Some beneficial conclusions are gained ,which can improve the integral circuit further, the measurement accuracy of electronic current transducers is improved.
