摘　　要：针对大电流直流铜排电流测量,提出了一种基于矩形阵列的非接触式电流测量方法,该方法在保证测量精度的同时,很好地简化了铜排电流的测量。对测量方法及原理进行了详细阐述,并提出了一种能自动反馈调整的去偏心误差方法。利用有限元分析法对铜排的磁场分布进行了仿真。并对去偏心误差方法及电流测量方法进行了仿真验证,仿真结果证明电流测量方法能够有效地测出铜排电流,且去偏心误差方法很好地降低了偏心误差的影响,进一步提高了电流测量精度。In order to measure the current of high-current DC copper bar, a non-contact current measurement method based on rectangular array was proposed, which simplified the measurement of copper bar current while ensuring the measurement accuracy.The measurement method and principle were elaborated in detail, and a method of eliminating eccentricity error with automatic feedback adjustment was proposed.The magnetic field distribution of copper bar was simulated by finite element analysis.And the method of removing eccentricity error and current measurement were verified by simulation.The simulation results show that the current measurement method can measure copper bar current effectively, and the effect of eccentricity error is reduced by the method of removing eccentricity error, and the current measurement accuracy is further improved.
