铝电解槽中与阴极母线连接的柔性线的电阻布置被概括为三种模式。在每种模式下，分别引入了选择适当的弯曲电阻率的通用方法，以确保局部弯曲组中的电流相等。此外，通过有限元方法建立了基于350 kA铝电解槽的电场模型来评估该方法的效果。并对三种模式的选择提出了建议。结果表明，与原始情况相比，电阻优化方法可以减少约180 A的电流变化。
The resistance arrangements of the flexes connecting with the cathode bus bar in aluminum reduction cells were generalized as three modes. In each mode the universal method to select proper resistivity of the flexes was induced respectively to insure that the current in local group of flexes was equal. Furthermore, a 350 kA aluminum reduction cell based electric field model was developed by finite element method to evaluate the effect of the method. Suggestions on selection of three modes were also put forward. The results show that the methods of resistance optimization can reduce the current variation about 180 A compared with that in original case.
