一种实用的电子式电流互感器研制

The Development for a Applied Electronic Current Transducer

本文对于电子式电流互感器传感头采用的模拟积分调理电路存在的缺陷,提出了实用改进型模拟积分器,降低了模拟积分器的积分漂移,提高了其抑制低频噪声能力。研制了由Rogowski线圈和改进型积分电路组成的实用电子式电流互感器,并对其进行了整体性能测试,得到了较好的效果。

Direct against insufficient of analog integrator, this paper has put forward a kind of practical improvement analog integrator, which can reduce drift of the integrator, and restrain low frequency noise. And manufactures an electronic current transducer which composed of Rogowski coil and analog integrator. By the view of experimental result, the whole system has the higher precision of measurement and the ability to measure the instantaneous response of current.
