中文摘要: 提出一种通过测量有限长矩形导体周围磁场来计算导体内电流的方法。该方法基于毕奥—萨伐尔(Biot-Savart)定律，通过MATLAB仿真，建立了能对有限长矩形导体周围磁感应强度求精确解的三重积分模型，并拟合数据得出形状系数的简化解析式。在此基础上，提出了一种能够消除干扰磁场的方法并给出了数学表达式。最后，推导出电流计算模型。理论验证和现场数据分析表明，该方法可以实时监测阳极电流分布。
Abstract:A method to measure magnetic field around conductor to calculate current in finite rectangle conductor was put forward based on Biot-Savart law. The triple integral model for a precise calculation of magnetic induction intensity around the conductor was established by MATLAB simulation and the simplified analysis formula of shape factor was obtained by fitting data. A method to eliminate interference fields was proposed, the mathematical expressions were provided, and the anode current calculation model for aluminum reduction cell was derived. The feasibility of this method in real-time monitoring of anode current distribution is verified by both theoretical verification and field measurements analysis.
