摘　　要：针对研制的点阵式霍尔电流传感器工程应用中的抗干扰能力及安装要求问题,基于点阵式霍尔电流传感器模型和应用环境,建立平行导线磁场对霍尔电流传感器测量准确度影响的计算模型,提出该情况下传感器测量准确度的计算方法,发现传感器测量准确度与点阵个数、点阵半径、干扰源电缆与被测电缆的距离、干扰源电流与被测电流之比值大小有关。理论计算和实验结果都显示了算法的正确性和实用性,该算法对传感器的设计及安装具有指导意义。Interference rejection and installation requirement must be taken into account for circular arrays of solid-state magnetic sensors applications..4 calculation formula is given in the unsaturated state of sensing elements, according to external interference rejection model in the parallel conductor magnetic field. Relationships between measuring accuracy and sensors number, radius of circular arrays, distance from measured conductor to parallel conductor, current intensity ratio of measured conductor and parallel conductor are discovered. Comparing the test result and theoretical derivation, conclusion can be drawn that the calculation formula is suitable for estimation error, this model and formula are useful for estimation error and transducer installation.
