| 摘 要： | 运用有限元法分析计算大型铝电解槽的磁场分布和主要影响因素。用Biot-Savart定律的线电流形式直接计算槽周母线电流产生的磁场，结果与用有限元法计算的差别是不大的。槽内电流产生的磁场需用矢量磁位表示，其满足泊松方程。铁磁物质的影响为铁磁屏蔽作用。将各项计算结果进行矢量叠加，便可得出总的磁场分布，与实测值基本相符。

| Abstract: | The magnetic field distribution and influencing factors of large aluminum reduction cell are investigated by using the finite element method The calculation result of magnetic field produced by conducting wire around the cell with Biot-Savart direct calculation is similar to that with finite element method The magnetic field from current inside the cell should be presented with magnetic vector potential, it is consonant with Poisson equation The ferromagnetic substances play the role of ferromagnetic shield The distribution of total magnetic field in the cell derived from vector addition of every factor approximately corresponds with the result of actual measurement |
