摘要: 对光学电流传感器测量电流时存在的相邻导线磁串扰问题进行了研究,提出了一种利用传感头的摆放位置和角度来消除磁串扰对电流测量影响的方法.通过理论分析给出了磁串扰的大小与两导线间距以及传感头与主导线的距离和夹角之间的定量关系,从而确定测量条件下的传感头的最佳摆放方案,并以此为依据进行了相应的实验测量和分析,结果表明当传感头处于最佳摆放位置时较好的消除了相邻导线磁串扰的影响,提高了光学电流传感器的测量精度.

Abstract: A method was presented to eliminate the effect of magnetic crosstalk on the current measurement by adjusting the position and angle of the optical current sensor.The quantitative relationship between the magnetic crosstalk and the distance between the two conductors and the distance and the angle between the sensor head and the main conductor is analyzed theoretically, and the optimal position of the sensor was determined.The experimental results show that the influence of the magnetic crosstalk of adjacent conductors can be minimized by adjusting the sensor's position, and the measurement precision of the optical current sensor is improved.
