摘要

提出了一种用于小电流测量的印制电路板（PCB）平面型Rogowski线圈电流互感器，给出了其结构和工作原理，推导出了线圈互感系数的计算公式，并分析了其抗外磁场干扰的机理，设计了实验模型。测试结果显示:额定100 A的小电流测量准确度达到了0.2级，具有较强的抗电磁干扰能力和抗直流能力，适合作为电子式电能表和继电保护专用电流变换器，也可用于抗直流领域的小电流测量。这对于开发新型电流互感器具有积极的意义。

Abstract

This paper presents a planar Rogowski coil current transformer based on PCB for low current measurement. Its structure and working principle are given. Formula for calculating the coil's coefficient of mutual inductance is derived. Anti-interference mechanism of external magnetic field is analyzed. Experimental model is designed， and the test results show that the transformer model of rated 100 A has an accuracy of 0.2 for low current measurement， strong anti-electromagnetic interference ability and anti-DC interference ability. It is suitable for a special current converter of electronic power meter and relay protection， and can also be used for low current measurement in areas of anti-DC. So it has a positive significance for the development of new current transformer.
